Analog Devices Inc. EV-AD4020REFDGNZ Reference Design Board
Analog Devices EV-AD4020REFDGNZ Reference Design Board integrates a unique Analog Devices programmable gain instrumentation amplifier (PGIA). The EV-AD4020-REF-DGNZ is optimized for 20-bit precision and provides superior linearity. The Board offers a typical integral nonlinearity (INL) of ±2ppm, low offset/gain, error drift, and trackable noise. Furthermore, the Reference Board features distortion (over -115dB) performance at a full speed of 1.8MSPS for all gain options.
The Reference Design Board incorporates a 20-bit, 1.8MSPS, successive approximation register (SAR) analog-to-digital converter (ADC), a 5V reference, a reference buffer, and onboard power supply circuitry. The EV-AD4020-REF-DGNZ is ideal for high-end data acquisition instruments and automated test equipment applications that typically require high input impedance.
The EV-AD4020-REF-DGNZ Board is compatible with the Analog Devices EVAL-SDPCH1Z system demonstration platform (SDP-H1) controller board and interfaces to the SDP-H1 controller board via a 120-pin connector.
