AD7902BRQZ Description

Short technical summary and product information.

The AD7902BRQZ from Analog Devices is a high-speed, low-power, dual 16-bit successive approximation analog-to-digital converter (ADC). It offers a throughput rate of 1 MSPS and consumes only 12.0 mW at this speed.

 

This ADC features a pseudo-differential analog input range from 0 V to VREF, with an externally applied reference voltage between 2.4 V and 5.1 V. It operates from a single 2.5 V supply and is compatible with 1.8 V, 2.5 V, 3 V, or 5 V logic interfaces via separate VIOx supplies. The device includes a versatile serial port interface (SPI) that is QSPI/MICROWIRE/DSP compatible.

 

Designed for applications requiring precise data acquisition, the AD7902BRQZ is suitable for battery-powered equipment, communications systems, and medical instrumentation. It is available in a compact 20-lead QSOP package and operates across a wide temperature range of -40°C to +125°C.

 

Key electrical specifications include an Integral Non-Linearity (INL) of ±1.0 LSB typical, a Signal-to-Noise and Distortion Ratio (SINAD) of 91 dB at 1 kHz, and Total Harmonic Distortion (THD) of -105 dB at 1 kHz. The device supports simultaneous sampling and has a 1:1 ratio.
