Описание
AD7705 is a Sigma-Delta ADC acts as a complete analogue front ends for low frequency measurement application. The device employ a Σ-∆ conversion technique to realize up to 16bits of no missing codes performance. The selected input signal is applied to a proprietary, programmable-gain front end based around an analogue modulator. The modulator output is processed by an on chip digital filter. The first notch of this digital filter can be programmed via an on-chip control register, allowing adjustment of the filter cut-off and output update rate. It is ideal for use in smart, microcontroller, or DSP-based systems. The devices feature a serial interface that can be configured for 3-wire operation. Gain settings, signal polarity, and update rate selection can be configured in software using the input serial port. The parts contains self calibration and system calibration options to eliminate gain and offset errors on the part itself or in the system.
