Аналогово Цифровые Преобразователи (АЦП) AD7706BNZ

АЦП , 16 бит, 500 выборок/с, Дифференциальный, Последовательный, 4.75 В

The AD7706BNZ is a 3-channel 16-bit Sigma-Delta (Σ-Δ) Analogue to Digital Converter (ADC) for low frequency measurement applications. This 3-channel complete analogue front end device can accept low level input signals directly from a transducer and produce serial digital output. The selected input signal is applied to a proprietary, programmable-gain front end based around an analogue modulator. 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. Gain settings, signal polarity and update rate selection can be configured in software using the input serial port. The parts contain self-calibration and system calibration options to eliminate gain and offset errors on the part itself or in the system.
