Overview
The AD7899ARZ-2 is a high-performance, 14-bit analog-to-digital converter (ADC) produced by Analog Devices Inc. This component operates from a single +5 V supply and is designed for fast and low-power applications. It includes a successive approximation ADC, a track/hold amplifier, a 2.5 V reference, an on-chip clock oscillator, and signal conditioning circuitry. The AD7899ARZ-2 also features a high-speed parallel interface and supports various analog input ranges, including ±10 V, ±5 V, ±2.5 V, 0 V to +2.5 V, and 0 V to +5 V. Additionally, it has overvoltage protection on the analog inputs to prevent damage during conversions.
