AD7715, Sigma-Delta ADC

Data Sheet .
The AD7715 is a complete analog front end for low frequency measurement applications.

Features

* Charge-balancing ADC 16-bits no missing codes 0.0015% nonlinearity Programmable gain front end Gains of 1, 2, 32 and 128 Differential input capability Three-wire serial interface SPI-, QSPI™-, MICROWIRE™-, and DSP-compatible Ability to buffer the analog input 3 V (AD7715-3) or 5 V (AD7715-5) operati

Applications

* The part can accept low level input signals directly from a transducer and outputs a serial digital word. It employs a Σ-Δ conversion technique to realize up to 16 bits of no missing codes performance. The input signal is applied to a proprietary programmable gain front end based around an analog m
