24-bit sigma-delta ADC with integrated PGA and temperature sensor
The AD7794BRUZ is a 24-bit sigma-delta ADC from Analog Devices, sampling at 470 SPS, designed for precision measurement applications where low noise and high resolution are critical. It integrates a programmable gain amplifier (PGA) and an on-chip temperature sensor, allowing direct connection to low-level sensor outputs without external signal conditioning. With six differential inputs and a MUX-ADC configuration, it handles multi-channel sensor arrays in a single package, reducing BOM count and board space.
Operates from a single 2.7V to 5.25V supply on both analog and digital rails, simplifying power distribution — no separate AVDD/DVDD sequencing needed.
RoHS3 compliant (2011/65/EU + 2015/863), with full material declaration available from Analog Devices for regulatory submittals.
