The ADA4945-1 is a low noise, low distortion, fully differential amplifier with two selectable power modes. The device operates over a broad power supply range of 3 V to 10 V. The low dc offset, dc offset drift, and excellent dynamic performance of the ADA4945-1 makes it well suited for a variety of data acquisition and signal processing applications. The device is an ideal choice for driving high resolution, high performance successive approximation register (SAR) and ?-? analog-to-digital converters (ADCs) on 4 mA of quiescent current (full power mode). The device can also be selected to operate on 1.4 mA of quiescent current (low power mode) to scale the power consumption to the desired performance necessary for an ADC drive application. The adjustable common-mode voltage allows the ADA4945-1 to match the input common-mode voltage of multiple ADCs. The internal common-mode feedback loop provides exceptional output balance, as well as suppression of even order harmonic distortion products.With the ADA4945-1, differential gain configurations are achieved with a simple external feedback network of four resistors determining the closed-loop gain of the amplifier. The ADA4945-1 is fabricated using Analog Devices, Inc., proprietary, silicon germanium (SiGe), complementary bipolar process, enabling the device to achieve low levels of distortion with an input voltage noise of only 1.8 nV/?Hz (full power mode).The ADA4945-1 is available in a RoHS-complaint, 3 mm ? 3 mm, 16-lead LFCSP. The ADA4945-1 is specified to operate from ?40?C to +125?C.Applications Low power ?-?, PulSAR?, and SAR ADC drivers Single-ended to differential converters Differential buffers Medical imaging Process control Portable electronics

TPS25940x Evaluation Module

The ADuCM410 is a fully integrated, single package device that includes high performance analog peripherals together with digital peripherals (controlled by a 160 MHz Arm? Cortex?-M33 processor) and integrated flash for code and data.The analog-to-digital converter (ADC) on the ADuCM410 provides 16-bit, 2 MSPS data acquisition using up to 16 input pins that can be programmed for single-ended or differential operation with a programmable gain amplifier (PGA) or transimpedance amplifier (TIA) for voltage and current measurements. Additionally, the die temperature and supply voltages can be measured.The ADC input voltage is 0 V to VREF. A sequencer is provided that allows a user to select a set of ADC channels to be measured in sequence without software involvement during the sequence. The sequence can optionally repeat automatically at a user-selectable rate.Up to 12 channels of 12-bit voltage digital-to-analog converters (VDACs) are provided with output buffers supported.The ADuCM410 can be configured so that the digital and analog outputs retain their output voltages through a watchdog or software reset sequence. Therefore, a product can remain functional even while the ADuCM410 is resetting itself.The ADuCM410 has a low power Arm Cortex-M33 processor and a 32-bit reduced instruction set computer (RISC) machine that offers up to 240 MIPS peak performance with a floating-point unit (FPU). Also integrated are 2? 512 kB Flash/EE memories and 128 kB static random access memory (SRAM)?both with single-error correction (SEC) and double error detection (DED) error checking and correction (ECC). The flash comprises two separate 512 kB blocks supporting execution from one flash block and simultaneous writing and/or erasing of the other flash block.The ADuCM410 operates from an on-chip oscillator and has a phase-locked loop (PLL) of 160 MHz. This clock can optionally be divided down to reduce current consumption. Additional low power modes can be set via the ADuCM410 software.The device includes a management data input/output (MDIO) interface capable of operating up to 10 MHz. User programming is eased by incorporating physical address (PHYADR) and device address (DEVAD) hardware comparators. The nonerasable kernel code combined with flags in user flash allow user code to reliably switch between the two hardware independent flash blocks.The ADuCM410 integrates a range of on-chip peripherals that can be configured under software control, as required in the application. These peripherals include 2? universal asynchronous receiver transmitter (UART), 3? I2C, and 3? serial peripheral interface (SPI) serial input/output communication controllers, general-purpose inputs/outputs (GPIOs), 32-element programmable logic arrays (PLAs), five general-purpose timers, a wake-up timer (WUT), and a system watchdog timer (WDT). A 16-bit pulse-width modulation (PWM) with eight output channels is also provided.The GPIO pins (Px.x) power up in high impedance input mode. In output mode, the software chooses between open-drain mode and push/pull mode. The pull-up and pull-down resistors can be disabled and enabled in the software. The GPIO pins can be configured with different voltage levels according to the IOVDDx pin, such as 3.3 V, 1.8 V, and 1.2 V. In GPIO output mode, the inputs can remain enabled to monitor the GPIO pins. The GPIO pins can also be programmed to handle digital or analog peripheral signals, in which case, the pin characteristics are matched to the specific requirement.A large support ecosystem is available for the Arm Cortex-M33 processor to ease product development of the ADuCM410. Access is via the Arm serial wire debug port. On-chip factory firmware supports in-circuit serial download via MDIO or I2C. These features are incorporated into a low cost, quick start development system supporting this precision analog microcontroller.Note that throughout this data sheet, multifunction pins, such as VDAC7/P4.2, are referred to either by the entire pin name or by a single function of the pin, for example, P4.2, when only that function is relevant.APPLICATIONS Optical networking 100 Gbps/200 Gbps/400 Gbps and higher frequency modules Industrial control, automation, and instrumentation systems

The Analog Devices, Inc., amplifier mezzanine card (AMC) analog-to-digital converter (ADC) driver evaluates the performance of amplifiers in 8-lead, single and dual SOIC, 6-lead single SOT23, 8-lead dual MSOP, and 16-lead LFCSP packages. This add on board can be inserted on ADC evaluation boards using its 7-pin header. Figure 1 shows the AMC mounted on an Analog Devices, Inc., ADC evaluation board. The AMC can support any of Analog Devices operational amplifiers and ADC drivers in different packages. The user can configure the ADC driver as a Sallen-Key low-pass, high-pass, or band-pass filter, as a multiple feedback low-pass, high-pass, or band-pass filter, or as an inverting and noninverting operational amplifier. The user can also configure the AMC to drive a single-ended, fully differential, or a single-ended signal to a differential ADC. Optimized power and ground planes ensure low noise and high speed operation. Component placement and power supply bypassing are optimized for maximum circuit flexibility and performance. The AMC evaluation board accepts 0402 or 0603 surface mount technology (SMT) components, 1206 bypass capacitors, and 2.54 mm headers. All components are placed on the primary side.
