ADS1000

SBAS357A–SEPTEMBER 2006–REVISED OCTOBER 2007

LOW-POWER, 12-Bit ANALOG-TO-DIGITAL CONVERTER

with I²C™ INTERFACE

FEATURES

DESCRIPTION

The ADS1000 is an I²C-compatible serial interface

Analog-to-Digital (A/D) converter with differential

inputs and 12 bits of resolution in a tiny SOT23-6

package. Conversions are performed ratiometrically,

using the power supply as the reference voltage. The

ADS1000 operates from a single power supply

ranging from 2.7V to 5.5V.

•

Complete 12-Bit Data Acquisition System in

a Tiny SOT-23 Package

•

Low Current Consumption: Only 90μA

Integral Nonlinearity: 1LSB Max

Single-Cycle Conversion

Programmable Gain Amplifier

Gain = 1, 2, 4, or 8

The ADS1000 performs conversions at a rate of 128

samples per second (SPS). The onboard

programmable gain amplifier (PGA), which offers

gains of up to 8, allows smaller signals to be

measured with high resolution. In single-conversion

mode, the ADS1000 automatically powers down after

a conversion, greatly reducing current consumption

during idle periods.

•

128SPS Data Rate

I²C Interface with Two Available Addresses

Power Supply: 2.7V to 5.5V

Pin- and Software-Compatible with 16-Bit

ADS1100

APPLICATIONS

The ADS1000 is designed for applications where

space and power consumption are major

considerations. Typical applications include portable

instrumentation, consumer goods, and voltage

monitoring.
