AD7383BCPZ-RL7

AD7383 is a 16bit pin-compatible, dual simultaneous sampling, high speed, low power, successive approximation register (SAR), analogue-to-digital converter (ADC) that operate from a 3.0V to 3.6V power supply and feature throughput rates up to 4MSPS. The analogue input type is pseudo differential and is sampled and converted on the falling edge of CS (active low). Integrated on-chip oversampling blocks improve dynamic range and reduce noise at lower bandwidths. A buffered internal 2.5V reference is included. Alternatively, an external reference up to 3.3V can be used. The conversion process and data acquisition use standard control inputs that allow simple interfacing to microprocessors or digital signal processors (DSPs). Application includes motor control position feedback, motor control current sense, sonar, power quality, data acquisition systems, erbium doped fibre amplifier (EDFA) applications, I and Q demodulation.
