The AD7732 is a high precision, high throughput analog front end. With a total conversion time of 500 µs (2 kHz channel switching), true 16-bit p-p resolution is achievable, making it ideally suitable for high resolution multiplexing applications. The part can be configured via a simple digital interface, which allows users to balance the noise performance against data throughput up to a 15.4 kHz.
The AD7732 is a high precision analog front-end featuring two fully differential input channels with unipolar or true bipolar ranges up to +10 V. It operates from a single +5 V analog supply and includes an overvoltage tolerant design capable of handling inputs up to +16.5 V without affecting adjacent channels.
The device supports high data throughput rates, achieving 24-bit resolution with no missing codes at conversion rates up to 15.4 kHz when chopping is disabled. It features a 3-wire serial interface compatible with SPI, QSPI, MICROWIRE, and DSP protocols, allowing for flexible configuration via digital registers.
