7.1 Overview

The ADS7066 is a 16-bit, successive approximation register (SAR) analog-to-digital converter (ADC) with an analog multiplexer. This device integrates a reference, reference buffer, low-dropout regulator (LDO), and features high performance at full throughput and low-power consumption.

The ADS7066 supports unipolar, single-ended analog input signals. The internal reference generates a low-drift, buffered, 2.5-V reference output. The device uses an internal clock to perform conversions. At the end of the conversion process, the device enters an acquisition phase.
