ADS1232IPWR -24-Bit, Delta-Sigma ADCs for Bridge Sensors
₹650.00
ADS1232IPWR is 24-bit precision analog-to-digital converter (ADCs). The ADS123x provides a full front-end solution for bridge sensor applications such as weigh scales, strain gauges, and pressure sensors thanks to its low-noise programmable gain amplifier (PGA), precision delta-sigma ADC, and internal oscillator. A differential input multiplexer (MUX) can receive two (ADS1232) or four (ADS1234) differential inputs. The ADS1232 also has a temperature sensor to monitor the outside temperature. The low-noise PGA supports a full scale differential input of 2.5 V, 1.25 V, 39 mV, or 19.5 mV and has a selectable gain of 1, 2, 64, or 128. The delta-sigma ADC has a maximum effective resolution of 23.5 bits and two data rates: 10 SPS (with 50-Hz and 60-Hz rejection) and 80 SPS.? directly connected to the MSP430 and other microcontrollers.
ADS1232IPWR -24-Bit, Delta-Sigma ADCs for Bridge Sensors – ADS1232 and ADS1234 (ADS123x) are precision, 24-bit, analog-to-digital converters (ADCs). With a low-noise programmable gain amplifier (PGA), a precision delta-sigma ADC, and an internal oscillator, the ADS123x provides a complete front-end solution for bridge sensor applications including weigh scales, strain gauges, and pressure sensors.
An input multiplexer (MUX) accepts either two (ADS1232) or four (ADS1234) differential inputs. The ADS1232 also includes a temperature sensor to monitor the ambient temperature. The low-noise PGA has a selectable gain of 1, 2, 64, or 128, supporting a full-scale differential input of ?2.5 V, ?1.25 V, ?39 mV, or ?19.5 mV.
The delta-sigma ADC provides a maximum of 23.5-bits effective resolution and supports two data rates: 10 SPS (providing 50-Hz and 60-Hz rejection) and 80 SPS. The ADS123x can be clocked externally using an oscillator or a crystal, or by the internal oscillator.
Offset calibration is performed on-demand, and the ADS123x can be put in a low-power standby mode or shut off completely in power-down mode. The ADS123x is operated through simple pin-driven control?there are no digital registers to program.
Data are output over a two-wire serial interface that connects directly to the MSP430 and other microcontrollers.
