The AD7723 is a complete 16-bit, sigma-delta ADC with a 1.2 MSPS output word rate and a 32×/16× oversampling ratio. It features low-pass and band-pass digital filters, linear phase, on-chip 2.5V voltage reference, standby mode, flexible parallel or serial interface, and more.
The AD7723 is a complete 16‑bit sigma‑delta analog‑to‑digital converter that operates from a single 5 V supply. It continuously samples the analog input, eliminating the need for an external sample‑and‑hold, and uses an on‑chip FIR digital filter with selectable oversampling ratios to achieve high performance.
Key features include a 1.2 MSPS output word rate, flexible parallel or serial data interfaces (including a stereo mode), an on‑chip 2.5 V reference (or external reference option), and operation over an industrial temperature range of –40 °C to +85 °C. The device is offered in a 44‑lead MQFP package.
