AD7731BR Description

Short technical summary and product information.

The AD7731BR is a complete analog front-end for process control applications, integrating a 24-bit Sigma-Delta ADC with a programmable gain amplifier (PGA). It accepts three buffered differential analog inputs configurable as five pseudo-differential inputs, with a differential reference input. The device operates from a single +5 V supply and supports unipolar and bipolar input ranges. The maximum sampling rate is 6.4 kHz, and the peak-to-peak resolution reaches 16 bits at 800 Hz output rate. The data interface includes SPI and DSP-compatible serial interfaces. The ADC is housed in a 24-SOIC surface mount package and operates over the industrial temperature range of -40°C to 85°C.
