This document describes the features and characteristics of the AD7813 8-/10-bit sampling ADC from Analog Devices, including operating voltage range, conversion time, interface type, power consumption, etc.
The AD7813 is a microprocessor‑compatible analog‑to‑digital converter offering 8‑/10‑bit resolution, a 2.3 µs conversion time, and automatic power‑down for low‑power operation. It operates from a single 2.7 V to 5.5 V supply and is available in DIP, SOIC and TSSOP packages.
The device features an 8‑bit parallel interface, on‑chip track‑and‑hold, and dynamic specifications such as SNR and THD for DSP applications. Power consumption is 10.5 mW in normal mode and as low as 34.6 µW at 1 kSPS in power‑down mode.
