Overview
Data Sheet 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) operation Low supply current: 450 µA maximum @ 3 V supplies Low-pass filter with programmable output update 16-lead SOIC/PDIP/TSSOP GENERAL DESCRIPTION The AD7715 is a complete analog front end for low frequency measurement 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 modulator.
The modulator output is processed by an on-chip digital filter.
The first notch of this digital filter can be programmed via the on-c...
