AD4683BCPZ-RL7

AD4683 is a 16bit, pin-compatible family of dual, simultaneous sampling, high speed, low power, successive approximation register (SAR), analogue-to-digital converter(ADC) that operate from a 3V to 3.6V power supply and feature throughput rates upto 500kSPS for the device. The analogue input type is pseudo differential and is sampled and converted on the falling edge of CS. Integrated on-chip oversampling blocks improve dynamic range and reduce noise at lower bandwidths. A buffered internal 2.5V reference is included. The conversion process and data acquisition use standard control inputs that allow simple interfacing to microprocessors or digital signal processors (DSPs). It is used in applications such as motor control position feedback, motor control current sense, sonar, power quality, data acquisition systems, erbium doped fibre amplifier (EDFA) applications, inphase (I) and quadrature (Q) demodulation.
