AD738x-4 Series Analog-to-Digital (ADC)

ADI's AD738x-4 family of quad ADCs offer a unique combination of simultaneous sampling channels and high speeds in a tiny package to optimize system responsiveness in closed-loop applications and reduce form factor by enhancing signal chain channel density. These products significantly simplify both the analog front end and digital back end around the ADC with an integrated on-chip oversampling block and an ability to process wide common mode signals without the need for complex analog input circuitry.

• AD7380-4: Differential input, quad, external reference simultaneous sampling, 16-bit, SAR ADC
• AD7381-4: Differential input, quad,14-bit, simultaneous sampling, SAR ADC
• AD7389-4: Differential input, quad, internal reference simultaneous sampling, 16-bit SAR ADC

The EVAL-AD7380-4FMCZ is a fully featured evaluation board designed to evaluate all features of the AD7380-4 analog-to-digital converter (ADC). It can be controlled by the high-speed system demonstration platform, EVAL-SDP-H1 controller board via the 160-way system demonstration platform (SDP) connector, P7. The SDP-H1 board controls the EVAL-AD7380-4FMCZ through the USB port of the PC using the analysis, control, evaluation (ACE) software, which is available for download on the ACE software page. Note that the EVAL-AD7380-4FMCZ can also be used to evaluate the AD7389-4 by moving JP4 to Position 3 and removing R5 to select the internal reference. The EVAL-AD7380-4FMCZ can also be used to evaluate the AD7381-4 by adjusting the number of clock cycles in the software.
