Overview
The AD7788ARMZ, produced by Analog Devices Inc., is a 16-bit, single-channel, ultra-low power, sigma-delta analog-to-digital converter (ADC). This device is designed for low frequency measurement applications and is known for its low power consumption and high precision. The AD7788 operates from an internal clock, eliminating the need for an external clock source, and it supports a single power supply from 2.5 V to 5.25 V. The device is available in a 10-lead Mini Small Outline Package (MSOP).
