5pcs CJMCU-1232 ADS1232 Analog-to-Digital Converter Board ADS1232IPWR Ultra Low Noise

Description The ADS1232 and ADS1234 are precision 24 bit analog to digital converters ADCs With an onboard low noise programmable gain amplifier PGA precision ADC and internal oscillator the ADS1232 4 provide a complete front end solution for bridge sensor applications including weigh scales strain gauges and pressure sensors The input multiplexer accepts either two ADS1232 or four ADS1234 differential inputs The ADS1232 also includes an onboard temperature sensor to monitor ambient temperature The onboard low noise PGA has a selectable gain of 1 2 64 or 128 supporting a full scale differential input of 2 5V 1 25V 39mV or 19 5mV The ADC has 23 5 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 ADS1232 4 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 ADS1232 4 can be put in a low power standby mode or shut off completely in power down mode All of the features of the ADS1232 4 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 The ADS1232 is available in a TSSOP 24 package and
