The AD7767/AD7767-1/AD7767-2 are high performance, 24-bit, oversampled SAR analog-to-digital converters (ADCs). The AD7767/AD7767-1/AD7767-2 combine the benefits of a large dynamic range and input bandwidth, consuming 15 mW, 10.5 mW, and 8.5 mW power, respectively, and are contained in a 16-lead TSSOP package.Ideal for ultralow power data acquisition (such as PCI- and USB-based systems), the AD7767/AD7767-1/AD7767-2 provide 24-bit resolution. The combination of exceptional SNR, wide dynamic range, and outstanding dc accuracy make the AD7767/AD7767-1/AD7767-2 ideally suited for measuring small signal changes over a wide dynamic range. This is particularly suitable for applications where small changes on the input are measured on larger ac or dc signals. In such an application, the AD7767/AD7767-1/AD7767-2 accurately gather both ac and dc information.The AD7767/AD7767-1/AD7767-2 include an on-board digital filter (complete with linear phase response) that acts to elimi-nate out-of-band noise by filtering the oversampled input voltage. The oversampled architecture also reduces front-end antialias requirements. Other features of the AD7767 include a SYNC/PD (synchronization/power-down) pin, allowing the synchronization of multiple AD7767 devices. The addition of an SDI pin provides the option of daisy chaining multiple AD7767 devices.The AD7767/AD7767-1/AD7767-2 operate from a 2.5 V supply using a 5 V reference. The devices operate from ?40?C to +105?C.ApplicationsLow power PCI/USB data acquisition systems Low power wireless acquisition systems Vibration analysis Instrumentation High precision medical acquisition

DC1747A-B: Demo Board for LTM2882 Dual Isolated RS232 µModule Transceiver + Power.

Demonstration circuit 1750A is a 42V, 2.5A micropower synchronous step-down regulator with current sense featuring the LT8611. The LT8611 is a compact, high efficiency, high speed synchronous monolithic step-down switching regulator that consumes only 2.5μA of quiescent current when the output is regulated at 3.3V. The demo board has an input voltage range from 3.8V to 42V and provides an output of 3.3V @ 2.5A. The current limit can be moved to the input side for application where input supply current is limited, such as energy harvesting application. ICTRL and IMON on the board set and monitor the regulated current respectively.

Demonstration Circuit 1754A features the LTC3104, a high efficiency, monolithic synchronous step-down converter using a current mode architecture capable of supplying 300mA of output current. The IC operates with a fixed frequency oscillator at 1.2MHz. The LTC3104 also incorporates a programmable LDO which can be operated from VIN, VOUT or an independent supply. The LDO can also be independently turned off or on. The LTC3104 operates with a 2.5V to 15V input voltage range. The demo board has been designed with the main output set to 3.3V and the LDO output (VLDO) to 1.8V.

Demonstration circuit DC1755A provides the user with two high current dual phase synchronous buck converters driven by the LTC3860. These buck converters provide outputs of 1.5V/50A and 1.2V/50A over an input voltage range of 6V to 14V and a switching frequency of 500kHz. The board can be easily modified for a 4-phase, single VO, 100A supply. The power stage for each phase consists of the tri-state PWM compatible 6mm × 6mm Fairchild DrMOS module and a 0.47μH 13.2mm × 12.8mm iron powder type inductor from Würth. A high density, two sided drop-in layout is used. The entire converter, excluding the bulk output and input capacitors, fits within a 2.25” × 1.38” area on the board.

The LTC3122 is a synchronous step-up DC/DC converter with true output disconnect and inrush current limiting. The 2.5A current limit along with the ability to program output voltages up to 15V makes the LTC3122 well suited for a variety of demanding applications. Once started, operation will continue with inputs down to 500mV, extending runtime in many applications.The LTC3122 features output disconnect in shutdown, dramatically reducing input power drain and enabling VOUT to completely discharge. Adjustable PWM switching from 100kHz to 3MHz optimizes applications for highest efficiency or smallest solution footprint. The oscillator can also be synchronized to an external clock for noise sensitive applications. Selectable Burst Mode operation reduces quiescent current to 25?A, ensuring high efficiency across the entire load range. An internal soft-start limits inrush current during start-up.Other features include a <1?A shutdown current and robust protection under short-circuit, thermal overload, and output overvoltage conditions. The LTC3122 is offered in both a low profile 12-lead (3mm ? 4mm ? 0.75 mm) DFN package and a 12-lead thermally enhanced MSOP package.Applications RF Power Piezo Actuators Small DC Motors 12V Analog Rail From Battery, 5V, or Backup Capacitor
