AD7791BRMZ Description

Short technical summary and product information.

The AD7791BRMZ is a low power, 24-bit Sigma-Delta analog-to-digital converter (ADC) from Analog Devices. It features a single differential input with a rail-to-rail input buffer and operates from an internal clock oscillator. The device supports a sampling rate of 120 Hz and provides simultaneous 50 Hz and 60 Hz rejection, making it suitable for low-frequency measurement applications.

 

The ADC achieves 19.5-bit peak-to-peak resolution (22 bits effective) with typical RMS noise of 1.1 µV at 9.5 Hz update rate. Integral nonlinearity is typically 3.5 ppm. The converter operates from a supply voltage range of 2.5V to 5.25V, drawing only 75 µA in normal mode and 1 µA in power-down mode.

 

The AD7791BRMZ is housed in a 10-MSOP surface-mount package and operates over -40°C to +105°C temperature range. The serial interface is SPI/DSP compatible. Typical applications include smart transmitters, battery-powered instruments, portable instrumentation, sensor measurement, temperature measurement, pressure measurement, weigh scales, and 4-20 mA loops.
