Dual 16-Bit ADC + Prog Gain

The AD7705/AD7706 are complete analog front ends for low frequency measurement applications. These 2-/3-channel devices can accept low level input signals directly from a transducer and produce serial digital output. The devices employ a Σ-Δ conversion technique to realize up to 16 bits of no missing codes performance. The selected input signal is applied to a proprietary, programmable-gain front end based around an analog modulator. The modulator output is processed by an onchip digital filter. The first notch of this digital filter can be programmed via an on-chip control register, allowing adjustment of the filter cutoff and output update rate.

The CJMCU-7705 TM7705 is ideal for intelligent systems, microcontroller systems and DSP-based systems. The serial interface can be configured as a three-wire interface. The gain value, the polarity of the signal, and the selection of the update rate can be configured by software using the serial input port. The device also includes self-calibration and system calibration options to eliminate the gain and offset errors of the device itself or the system. CMOS architecture ensures extremely low power consumption, power-down mode reduces power consumption to 20μW (typical).
