INTRODUCTION

This Technical Note describes the evaluation board for the AD7719, Low Voltage, Low Power, 16&24-Bit, Dual Sigma Delta ADC. The AD7719 is a complete analog front end for low frequency measurement applications. The AD7719 is factory calibrated and therefore does not require field calibration. The device can accept low level input signals directly from a transducer and produce a serial digital output. It employs a sigma-delta conversion technique to realize up to 24 bits (Main ADC) or 16 bits (Auxiliary ADC) of no missing codes performance.
