Overview
The AD7719BRZ, produced by Analog Devices Inc., is a low voltage, low power, 16-/24-bit dual sigma delta Analog-to-Digital Converter (ADC). This component is designed as a complete analog front-end for low frequency measurement applications. It integrates two high-resolution sigma delta ADCs, switchable matched excitation current sources, low-side power switches, a digital I/O port, and a temperature sensor. This makes it highly suitable for direct conversion of signals from transducers without the need for additional signal conditioning.
