Introduction
The AD7858 is a high-performance, low-power, 12-bit successive approximation analog-to-digital converter (ADC) that operates from a single 3 V to 5.5 V power supply. The device can convert analog input signals in the range of 0 V to VREF or ±VREF to a 12-bit digital word. The AD7858 features an on-chip track-and-hold circuit, allowing it to accurately convert ac as well as dc signals.
