AD7719BRZ Description

Short technical summary and product information.

The AD7719BRZ is a complete analog front end for low frequency measurement applications, integrating two high-resolution sigma-delta ADCs. The main ADC provides 24-bit no missing codes performance, while the auxiliary ADC offers 16-bit resolution. Both converters operate from a 2.7V to 3.6V or 5V supply and feature a programmable gain amplifier (PGA) and multiplexer for flexible input configuration.

 

The device supports differential, pseudo-differential, and single-ended inputs, with up to six input channels. It includes on-chip functions such as a temperature sensor, dual switchable excitation current sources, and low-side power switches. The SPI/DSP serial interface allows easy connection to microcontrollers and DSPs.

 

Housed in a 28-SOIC surface-mount package, the AD7719BRZ operates over the industrial temperature range of -40°C to 85°C. Typical power dissipation is 4.5 mW with both ADCs enabled at 3V. The device is specified for single 3V and 5V operation, making it suitable for battery-powered and portable instrumentation.
