ADS7813

Low-Power, Serial 16-Bit Sampling

ANALOG-TO-DIGITAL CONVERTER

FEATURES

DESCRIPTION

● 20µs max CONVERSION TIME

● SINGLE +5V SUPPLY OPERATION

● PIN-COMPATIBLE WITH 12-BIT ADS7812

● EASY-TO-USE SERIAL INTERFACE

● 16-PIN 0.3" PLASTIC DIP AND SOIC

● ±2.0LSB max INL

The ADS7813 is a low-power, single +5V supply, 16-

bit sampling analog-to-digital converter. It contains a

complete 16-bit capacitor-based SAR A/D with a

sample/hold, clock, reference, and serial data inter-

face.

The converter can be configured for a variety of input

ranges including ±10V, ±5V, 0V to 10V, and 0.5V to

4.5V. A high impedance 0.3V to 2.8V input range is

also available (input impedance > 10MΩ). For most

input ranges, the input voltage can swing to +16.5V or

–16.5V without damage to the converter.

● 87dB min SINAD

● USES INTERNAL OR EXTERNAL

REFERENCE

● MULTIPLE INPUT RANGES

● 35mW max POWER DISSIPATION

● NO MISSING CODES

A flexible SPI compatible serial interface allows data

to be synchronized to an internal or external clock.

The ADS7813 is specified at a 40kHz sampling rate

over the –40°C to +85°C temperature range. It is

available in a 16-pin 0.3" plastic DIP or a 16-lead

SOIC package.

● 50µW POWER DOWN MODE
