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.

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.

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.

The ADS1230 is available in a TSSOP-16 package and is specified from -40°C to +85°C.
