SBAS043C – MARCH 1997 – REVISED SEPTEMBER 2005

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

ꢀ 0.3" DIP-16 AND SO-16

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

sampling analog-to-digital (A/D) converter. It contains a

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

sample/hold, clock, reference, and serial data interface.

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.

ꢀ ±2.0LSB max INL

ꢀ 87dB min SINAD

ꢀ USES INTERNAL OR EXTERNAL

REFERENCE

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 0.3" DIP-16 or

an SO-16 package.

ꢀ MULTIPLE INPUT RANGES

ꢀ 35mW max POWER DISSIPATION

ꢀ NO MISSING CODES

ꢀ 50µW POWER DOWN MODE
