The AD9253 is a quad, 14-bit, 80 MSPS/105 MSPS/125 MSPSanalog-to-digital converter (ADC) with an on-chip sample-and-holdcircuit designed for low cost, low power, small size,and ease of use. The product operates at a conversion rate ofup to 125 MSPS and is optimized for outstanding dynamicperformance and low power in applications where a smallpackage size is critical.The ADC requires a single 1.8 V power supply and LVPECL-/CMOS-/LVDS-compatible sample rate clock for full performanceoperation. No external reference or driver components arerequired for many applications.The ADC automatically multiplies the sample rate clock for theappropriate LVDS serial data rate. A data clock output (DCO) forcapturing data on the output and a frame clock output (FCO)for signaling a new output byte are provided. Individual-channelpower-down is supported and typically consumes less than 2 mWwhen all channels are disabled. The ADC contains several featuresdesigned to maximize flexibility and minimize system cost, such as programmable output clock and data alignment and digitaltest pattern generation. The available digital test patternsinclude built-in deterministic and pseudorandom patterns, alongwith custom user-defined test patterns entered via the serial portinterface (SPI).The AD9253 is available in a RoHS-compliant, 48-lead LFCSP.It is specified over the industrial temperature range of ?40?C to+85?C. This product is protected by a U.S. patent.PRODUCT HIGHLIGHTS Small Footprint. Four ADCs are contained in a small, spacesaving package.

The AD7176-2 is a fast settling, highly accurate, high resolution,multiplexed Σ-Δ analog-to-digital converter (ADC) for low bandwidthinput signals. Its inputs can be configured as two fullydifferential or four pseudo differential inputs via the integratedcrosspoint multiplexer. An integrated precision, 2.5 V, low drift(2 ppm/°C), band gap internal reference (with an outputreference buffer) adds functionality and reduces the externalcomponent count.The maximum channel scan data rate is 50 kSPS/channel(settling time of 20 µs), resulting in fully settled data with17 noise free bits. User-selectable output data rates range from5 SPS to 250 kSPS. The resolution increases at lower speeds.The AD7176-2 offers three key digital filters. The fast settlingsinc5 + sinc1 filter maximizes the channel scan rate. The sinc3filter maximizes the resolution for single-channel, low speedapplications. For 50 Hz and 60 Hz environments, the AD7176-2specific filter minimizes the settling times or maximizes therejection of the line frequency. These enhanced filters enablesimultaneous 50 Hz and 60 Hz rejection with a 27 SPS outputdata rate (with a settling time of 36 ms).System offset and gain errors can be corrected on a per channelbasis. This per channel configurability extends to the output datarate used for each channel when using a sinc5 + sinc1 filter. Allswitching of the crosspoint multiplexer is controlled by the ADCand can be configured to automatically control an externalmultiplexer via the GPIO pins.The specified operating temperature range is −40°C to +105°C.The AD7176-2 is housed in a 24-lead TSSOP package.Applications Process control: PLC/DCS modules - Temperature and pressure measurement Medical and scientific multichannel instrumentation Chromatography

The AD7237A / AD7247A is an enhanced version of the industry standard AD7237 / AD7247. Improvements include operation from 12 V to 15 V supplies, faster interface times and better reference variations with VDD. Additional features include faster settling times.The AD7237A / AD7247A is a complete, dual, 12-bit, voltage output digital-to-analog converter with output amplifiers and Zener voltage reference on a monolithic CMOS chip. No external user trims are required to achieve full specified performance.Both parts are microprocessor compatible, with high speed data latches and interface logic. The AD7247A accepts 12-bit parallel data which is loaded into the respective DAC latch using the WR input and a separate Chip Select input for each DAC. The AD7237A has a double buffered interface structure and an 8-bit wide data bus with data loaded to the respective input latch in two write operations. An asynchronous LDAC signal on the AD7237A updates the DAC latches and analog outputs.A REF OUT/REF IN function is provided which allows either the on-chip 5 V reference or an external reference to be used as a reference voltage for the part. For single supply operation, two output ranges of 0 V to +5 V and 0 V to +10 V are available, while these two ranges plus an additional ±5 V range are available with dual supplies. The output amplifiers are capable of developing +10 V across a 2 kΩ load to GND.The AD7237A / AD7247A is fabricated in Linear Compatible CMOS (LC2MOS), an advanced, mixed technology process that combines precision bipolar circuits with low power CMOS logic. Both parts are available in a 24-pin, 0.3' wide plastic and hermetic dual-in-line package (DIP) and are also packaged in a 24-lead small outline (SOIC) package.

The AD5426 / AD5432 / AD5443 are CMOS 8-, 10-, and 12-bit current output digital-to-analog converters (DACs), respectively. These devices operate from a 2.5 V to 5.5 V power supply, making them suitable for battery-powered applications and many other applications.These DACs use a double buffered, 3-wire serial interface that is compatible with SPI, QSPI™, MICROWIRE™, and most DSP interface standards. In addition, a serial data out pin (SDO) allows for daisy-chaining when multiple packages are used. Data readback allows the user to read the contents of the DAC register via the SDO pin. On power-up, the internal shift register and latches are filled with 0s and the DAC outputs are at zero scale.As a result of manufacturing on a CMOS submicron process, the parts offer excellent 4-quadrant multiplication characteristics with large signal multiplying bandwidths of 10 MHz. The applied external reference input voltage, VREF, determines the full-scale output current. An integrated feedback resistor, RFB, provides temperature tracking and full-scale voltage output when combined with an external current to voltage precision amplifier.The AD5426 / AD5432 / AD5443 DACs are available in small, 10-lead MSOP packages.The EVAL-AD5443SDZ / EVAL-AD5446SDZ / EVAL-AD5453SDZ evaluation board is available for evaluating DAC performance.
