AD7380-4BCPZ

AD7380-4 is a differential input, quad, external reference simultaneous sampling, 16bit, SAR ADC operating from a 3.3V power supply with throughput rates upto 4MSPS. The differential analogue input accepts a wide common-mode input voltage and is sampled and converted on the falling edge of CS (active high). It has on-chip oversampling blocks to improve dynamic range and reduce noise at lower bandwidths. The oversampling can boost up to two bits of added resolution. The REFIN pin can have a reference voltage 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). Application includes motor control position feedback, motor control current sense, data acquisition systems, erbium doped fibre amplifier (EDFA) applications, in phase and quadrature demodulation.
