Overview
The AD7298-1BCPZ is a high-performance, 10-bit, 8-channel successive approximation analog-to-digital converter (ADC) produced by Analog Devices Inc. This device is designed for high-speed, low-power applications and operates from a single 3.3 V power supply. It features a throughput rate of up to 1 MSPS and includes a low noise, wide bandwidth track-and-hold amplifier capable of handling input frequencies exceeding 30 MHz. The AD7298-1BCPZ also includes a programmable sequencer, allowing for the selection of a preprogrammable sequence of channels for conversion, and an on-chip 2.5 V reference voltage.
