FEATURES

DESCRIPTION

240SPS Data Rate with 4MHz Clock

20-Bit Effective Resolution

The ADS1224 is a 4-channel, 24-bit, delta-sigma ana-

log-to-digital (A/D) converter. It offers excellent perfor-

mance and low power in a TSSOP-20 package. The

ADS1224 is well-suited for demanding, high-resolution

measurements, especially in portable systems and oth-

er space-saving and power-constrained applications.

Input Multiplexer with Four Differential

Channels

Pin-Selectable, High-Impedance Input Buffer

5V Differential Input Range

A delta-sigma (∆Σ) modulator and digital filter form the

basis of the A/D converter. The analog modulator has

0.0003% INL (typ), 0.0015% INL (max)

Self-Calibrating

5V differential input range. An input multiplexer

(MUX) is used to select between four separate

differential input channels. A buffer can be selected to

increase the input impedance of the measurement.

Simple 2-Wire Serial Interface

On-Chip Temperature Sensor

Single Conversions with Standby Mode

Low Current Consumption: 300µA

Analog Supply: 2.7V to 5.5V

A simple, 2-wire serial interface provides all the

necessary control. Data retrieval, self-calibration, and

Standby mode are handled with a few simple

waveforms. When only single conversions are needed,

the ADS1224 can be quickly shut down (Standby mode)

while idle between measurements to dramatically

reduce the overall power consumption. Multiple

ADS1224s can be connected together to create a

synchronously sampling multichannel measurement

system. The ADS1224 is designed to easily connect to

microcontrollers, such as the MSP430.

Digital Supply: 2.7V to 5.5V

APPLICATIONS

Hand-Held Instrumentation

Portable Medical Equipment

Industrial Process Control

Weigh Scales

The ADS1224 supports 2.7V to 5.5V analog supplies

and 2.7V to 5.5V digital supplies. Power is typically less

than 1mW in 3V operation and less than 1µW during

Standby mode.
