The AD7192 is a 4.8 kHz ultra-low noise 24-bit Sigma-Delta ADC with PGA.
The AD7192 is a low‑noise, 24‑bit sigma‑delta analog‑to‑digital converter with a programmable gain amplifier (1‑128). It is designed for high‑precision measurement applications such as strain‑gauge transducers, pressure, temperature, and data‑acquisition systems.
The device operates from a 3 V to 5.25 V supply, consumes 3.5 mA, and offers an output data rate from 4.7 Hz to 4.8 kHz. It features a 3‑wire serial interface compatible with SPI®, QSPI™, and MICROWIRE™, four general‑purpose digital outputs, and extensive timing and register specifications for flexible integration.
