AD7705/AD7706
PRODUCT HIGHLIGHTS
1.
2.
The AD7705/AD7706 devices consume less than 1 mW at
3 V supplies and 1 MHz master clock, making them ideal
for use in low power systems. Standby current is less than 8
μA.
The programmable gain input allows the AD7705/AD7706
to accept input signals directly from a strain gage or
transducer, removing a considerable amount of signal
conditioning.

4.
The AD7705/AD7706 are ideal for microcontroller or DSP
processor applications with a 3-wire serial interface,
reducing the number of interconnect lines and reducing
the number of opto-couplers required in isolated systems.
The parts feature excellent static performance
specifications with 16 bits, no missing codes, ±0.003%
accuracy, and low rms noise (<600 nV). Endpoint errors
and the effects of temperature drift are eliminated by on-
chip calibration options, which remove zero-scale and full-
scale errors.
