AD7789BRMZ Description

Short technical summary and product information.

The AD7789BRMZ is a low-power, low-noise 24-bit sigma-delta analog-to-digital converter (ADC) from Analog Devices. It offers a resolution of 24 bits with a typical RMS noise of 1.5 µV and integral nonlinearity of 3.5 ppm. The device operates from a single 2.5V to 5.25V supply, consuming a maximum of 225 µW at 3V. It includes an internal clock oscillator and provides simultaneous 50 Hz and 60 Hz rejection, making it suitable for noisy environments.

 

The ADC features one differential input and requires an external voltage reference. The data interface is SPI and DSP compatible, with a Schmitt trigger on the SCLK input for robust communication. The sampling rate is 16.6 S/s, corresponding to an output data rate of 16.6 Hz.

 

The AD7789BRMZ is housed in a 10-lead MSOP package (10-MSOP) and is designed for surface-mount assembly. It operates over a temperature range of -40°C to 85°C. Typical applications include smart transmitters, battery-powered instrumentation, portable measurement devices, sensor signal conditioning, temperature and pressure measurement, weigh scales, and 4-20 mA loop systems.
