The ADS1230IPW is a precision Analog-to-digital Converter (ADC) with an on board low-noise programmable gain amplifier (PGA), on board oscillator and precision 20-bit delta-sigma ADC. The ADC provides a complete front-end solution for bridge sensor applications. The low-noise PGA has a gain of 64 or 128, supporting a full-scale differential input of ±39 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 and 80SPS. The ADC can be clocked by the internal oscillator or an external clock source. Offset calibration is performed on-demand and the ADC can be put in a low-power standby mode or shut off completely in power-down mode. All of the features of the ADC 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.
