GENERAL DESCRIPTION

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 (ADC) 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,

The AD7380/AD7381 are available in a 16-lead lead frame chip

scale package (LFCSP) with operation specified from −40°C to

+125°C.

PRODUCT HIGHLIGHTS

1. Dual simultaneous sampling and conversion with two

complete ADC functions.

2. Pin-compatible product family.

and is sampled and converted on the falling edge of

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.

3. High 4 MSPS throughput rate.

4. Space saving 3 mm × 3 mm LFCSP package.

5. Integrated oversampling block to increase dynamic range,

reduce noise, and reduce SCLK speed requirements.

6. Differential analog inputs with wide common-mode range.

7. Small sampling capacitor reduces amplifier drive burden.

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.
