Analog Devices AD7380

The AD7380/AD7381 are a 16-bit and 14-bit pin-compatible family of dual simultaneous sampling, high speed, low power, successive approximation register (SAR) analog-to-digital converters (ADCs) that operate from a 3.0 V to 3.6 V power supply and feature throughput rates up to 4 MSPS. The analog input type is differential, accepts a wide common-mode input voltage, and is sampled and converted on the falling edge of CS.

APPLICATIONS

Motor control position feedback Motor control current sense Sonar Power quality Data acquisition systems Erbium doped fiber amplifier (EDFA) applications I and Q demodulation

GENERAL DESCRIPTION

An integrated on-chip oversampling block improves dynamic range and reduces noise at lower bandwidths. A buffered internal 2.5 V reference is included. Alternatively, an external reference up to 3.3 V can be used. The conversion process and data acquisition use standard control inputs allowing simple interfacing to microprocessors or digital signal processors (DSPs).
