Analog Devices 16-Bit SAR Analog to Digital Converter

Added to your shopping cart

The AD7380 is a 16-bit pin-compatible analog-to-digital converter (ADC) that is part of the family of dual simultaneous sampling, high speed, low power, successive approximation registers (SAR) 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.

Integrated on-chip oversampling blocks improve dynamic range and reduce 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 easy interfacing to microprocessors or digital signal processors (DSPs). It is compatible with 1.8 V, 2.5 V, and 3.3 V interfaces, using the separate logic supply.
