ADS1230

SBAS366–OCTOBER 2006

20-Bit Analog-to-Digital Converter

For Bridge Sensors

FEATURES

DESCRIPTION

•

Complete Front-End for Bridge Sensor

Onboard PGA with Gain of 64 or 128

Onboard Oscillator

The ADS1230 is a precision 20-bit analog-to-digital

converter (ADC). With an onboard low-noise

programmable gain amplifier (PGA), onboard

oscillator, and precision 20-bit delta-sigma ADC, the

ADS1230 provides a complete front-end solution for

bridge sensor applications including weigh scales,

strain gauges, and pressure sensors.

RMS Noise:

40nV at 10SPS (G = 128)

88nV at 80SPS (G = 128)

•

18-Bit Noise-Free Resolution

The low-noise PGA has a gain of 64 or 128,

supporting a full-scale differential input of ±39mV or

±19.5mV, respectively. The delta-sigma ADC has

20-bit effective resolution and is comprised of a

3rd-order modulator and 4th-order digital filter. Two

data rates are supported: 10SPS (with both 50Hz

and 60Hz rejection) and 80SPS. The ADS1230 can

be clocked by the internal oscillator or an external

clock source. Offset calibration is performed

on-demand, and the ADS1230 can be put in a

low-power standby mode or shut off completely in

power-down mode.

Selectable 10SPS or 80SPS Data Rates

Simultaneous 50Hz and 60Hz Rejection at

10SPS

•

External Voltage Reference up to 5V for

Ratiometric Measurements

•

Simple, Pin-Driven Control

Two-Wire Serial Digital Interface

Tiny 16-pin TSSOP Package

Supply Range: 2.7V to 5.3V

–40°C to +85°C Temperature Range

All of the features of the ADS1230 are controlled by

dedicated pins; there are no digital registers to

program. Data are output over an easily-isolated

serial interface that connects directly to the MSP430

and other microcontrollers.

APPLICATIONS

•

Weigh Scales

Strain Gauges

Pressure Sensors

Industrial Process Control

The ADS1230 is available in a TSSOP-16 package

and is specified from –40°C to +85°C.
