1. The AD7705/AD7706 consumes less than 1 mW at 3 V supplies and 1Ê MHz master clock, making it ideal for use in low power systems. Standby current is less than 8Ê mA. 2. 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. 3. The AD7705/AD7706 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 opto-couplers required in isolated systems. 4. The part features excellent static performance specifications with 16 bits, no missing codes, ±0.003% accuracy and low rms noise (<600Ê nV). Endpoint errors and the effects of temperature drift are eliminated by on-chip calibration options, which remove zero-scale and full-scale errors.
