AD7783, READ ONLY, PIN CONFIGURED, 24-BIT SIGMA-DELTA ADC

Introduction

This Technical Note describes the evaluation board for the AD7783 which is a read-only, pin-configured, 24-Bit, Sigma Delta ADC. The AD7783 is a complete analog front end for low frequency measurement applications. 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 of no missing codes performance. The selected input signal is applied to a proprietary programmable gain front end based around an analog modulator. The modulator output is processed by an on-chip digital filter. Full data on the AD7783 is available in the AD7783 datasheet (available on the AD7783 Product Page) and should be consulted in conjunction with this Technical Note when using the evaluation board.
