AD7714YRUZ 5 Channel Analog to Digital Converters ADC 24-BIT SIGMA
DELTA A/D IC Data Converter ICs
PRODUCT HIGHLIGHTS
1. The AD7714Y offers the following features in addition to the
standard AD7714: wider temperature range, Schmitt trigger on SCLK
and DIN, operation down to 2.7 V, lower power consumption, better
linearity, and availability in 24-lead TSSOP package.
2. The AD7714 consumes less than 500 µA (fCLK IN = 1␣ MHz) or 1 mA
(fCLK IN = 2.5␣ MHz) in total supply current, making it ideal for
use in loop-powered systems.
3. The programmable gain channels allow the AD7714 to accept input
signals directly from a strain gage or transducer removing a
considerable amount of signal conditioning.
4. The AD7714 is ideal for microcontroller or DSP processor
applications with a three-wire serial interface reducing the number
of interconnect lines and reducing the number of optocouplers
required in isolated systems. The part contains on-chip registers
that allow control over filter cutoff, input gain, channel
selection, signal polarity and calibration modes.
5. The part features excellent static performance specifications
with 24-bit no missing codes, ±0.0015% accuracy and low rms noise
(140 nV). Endpoint errors and the effects of temperature drift are
eliminated by on-chip self-calibration, which removes zero-scale
and full-scale errors.
