AD7386-4BCPZ

AD7386-4BCPZ is a 16bit compatible, quad, simultaneous sampling, high-speed, successive approximation register (SAR), analogue-to-digital converter (ADC). It operates from a 3V to 3.3V power supply with throughput rates upto 4MSPS. The single-ended analogue input accepts voltage from 0V to VREF and is sampled and converted on the falling edge of (active-low) CS. It has on-chip oversampling blocks to improve dynamic range and reduce noise at lower bandwidths. The oversampling can boost upto two bits of added resolution. The REFIO pin can have a reference voltage (VREF) of 2.5V to 3.3V. The conversion process and data acquisition use standard control inputs, allowing easy interfacing to microprocessors or digital signal processors (DSPs). It is used in applications such as motor control position feedback, motor control current sense, data acquisition systems, erbium-doped fibre amplifier (EDFA) applications, traveling wave fault detection, and in-phase and quadrature demodulation.
