Overview
The AD7888ARU-REEL is a high-speed, low-power, 12-bit analog-to-digital converter (ADC) produced by Analog Devices Inc. This component operates from a single 2.7 V to 5.25 V power supply and is designed for applications requiring high throughput rates and low power consumption. The AD7888 features eight single-ended analog input channels, an on-chip track-and-hold circuit, and a successive-approximation ADC architecture. It is housed in a compact 16-lead TSSOP package, offering significant space-saving advantages.
