GENERAL DESCRIPTION

The AD7380-4 is a 16-bit compatible, quad, simultaneous

sampling, high speed, successive approximation register (SAR),

analog-to-digital converters (ADC) operating from a 3.3 V

power supply with throughput rates up to 4 MSPS. The

differential analog input accepts a wide common-mode input

The AD7380-4 has on-chip oversampling blocks to improve

dynamic range and reduce noise at lower bandwidths. The

oversampling can boost up to two bits of added resolution. The

Single-ended AD7386

AD7388

REFIN pin can have a reference voltage of 2.5 V to 3.3 V.

PRODUCT HIGHLIGHTS

The conversion process and data acquisition use standard

control inputs allowing easy interfacing to microprocessors or

digital signal processors (DSPs). The conversion result can

clock out simultaneously via 4-wire mode for faster throughput

or via 1-wire serial mode when slower throughput is allowed.

The device is compatible with 1.8 V, 2.5 V, and 3.3 V interfaces

using the separate logic supply.

1. Quad simultaneous sampling and conversion

2. Pin-compatible product family.

3. High throughput rate, 4 MSPS at 16-bit.

4. Space-saving, 4 mm × 4 mm LFCSP.

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 AD7380-4 is available in a 24-lead lead frame chip scale

package (LFCSP) and operates over a temperature range of −40°C

to +125°C.
