AD7714 - ADI Function Overview

Product Details
The AD7714 is a complete analog front end for low-frequency measurement applications. The device accepts low level signals directly from a transducer and outputs a serial digital word. It employs a sigma-delta conversion technique to realize up to 24 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-chip control register allowing adjustment of the filter cutoff and settling time.
The part features three differential analog inputs (which can also be configured as five pseudo-differential analog inputs) as well as a differential reference input. The AD7714 thus performs all signal conditioning and conversion for a system consisting of up to five channels. A new Y grade has recently been added to the existing range. Compared to the A grades this new grade has an extended operating temperature range, schmitt trigger inputs on SCLK and DIN, tighter linearity specifications, lower power consumption and is available in a smaller package.
The AD7714 is ideal for use in smart microcontroller- or DSP-based systems. It features a serial interface that can be configured for three-wire operation. Gain settings, signal polarity and channel selection can be configured in software using the serial port. The AD7714 provides self-calibration, system calibration and background calibration options and also allows the user to read and write the on-chip calibration registers.
CMOS construction ensures very low power dissipation, and the power-down mode reduces the standby power consumption to 15 µW typical at 3 V. Minimum operating voltage for the A grades is 3 V and 2.7 V for the Y grades. The A grades are available in a 24-pin, 0.3 inch-wide, plastic dual-in-line package (DIP); a 24 lead small outline (SOIC) package and a 28-lead shrink small outline package (SSOP). The new Y grade is available in a 24-pin, 0.3 inch-wide, plastic dual-in-line package (DIP); a 24 lead small outline (SOIC) package and a 24-lead Thin Shrink Small Outline Package (TSSOP).
