16-bit sigma-delta ADC with on-chip PGA and temperature sensor
The AD7795BRUZ is a 16-bit sigma-delta ADC from Analog Devices, integrating a programmable gain amplifier (PGA) and a temperature sensor on-chip. It samples at 470 SPS and accepts up to six differential inputs through an internal MUX, making it a single-chip front-end for precision measurement chains.
Resolution, sampling rate, and input architecture
The on-chip PGA amplifies low-level sensor signals before conversion, reducing the noise contribution from downstream stages. The integrated temperature sensor provides a local die-temperature readout useful for cold-junction compensation in thermocouple applications.
Supply, interface, and temperature grade
The SPI/DSP-compatible serial interface connects directly to a microcontroller or DSP without glue logic.
Package and board-fit
The 24-TSSOP footprint is common across the AD779x family, so a single PCB layout can accommodate multiple resolution grades.
Analog Devices lists the AD7795BRUZ as Active. It is ROHS3 Compliant.
