Overview
The AD7813YN, produced by Analog Devices Inc., is a high-speed, microprocessor-compatible, 8-/10-bit analog-to-digital converter (ADC). This device operates on a single supply voltage ranging from 2.7 V to 5.5 V and features a maximum throughput of 400 kSPS. The AD7813YN includes on-chip track and hold circuitry, a successive approximation A/D converter, and an 8-bit wide parallel interface, making it easy to interface with microprocessors and DSPs. The converter supports both 8-bit and 10-bit conversion results, with the 10-bit result read through two 8-bit read operations. The device is available in a 16-lead plastic dual-in-line package (DIP).
