ADS1232IPW .

The ADS1232IPW is a 24-bit precision Analog-to-digital Converter (ADC) with an on board, low-noise programmable gain amplifier (PGA), precision delta-sigma ADC and internal oscillator. The ADC provides a complete front-end solution for bridge sensor applications. The delta-sigma ADC has 23.5-bit effective resolution and is comprised of a 3rd-order modulator and 4th-order digital filter. The ADC can be clocked externally using an oscillator or a crystal. There is also an internal oscillator available that requires no external components. 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 operated through simple pin-driven control. There are no digital registers to program in order to simplify software development. Data are output over an easily-isolated serial interface that connects directly to the MSP430 and other microcontrollers.
