ADS1234IPW

TEXAS INSTRUMENTS  ADS1234IPW.  模数转换器, 24 bit, 80 SPS, 单, 2.7 V, 5.3 V, TSSOP

The is a 24-bit Analogue-to-digital Converter with an onboard, low-noise programmable gain amplifier PGA, precision delta-sigma ADC and internal oscillator, this ultra ADS1234 provides a complete front-end solution for bridge sensor applications including weigh scales, strain gauges and pressure sensors. The input multiplexer accepts four differential inputs. The ADC also includes an onboard temperature sensor to monitor ambient temperature. The delta-sigma ADC has 23.5-bit effective resolution and is comprised of a 3rd-order modulator and 4th-order digital filter. Supports 80SPS of data rate and 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 this ADC are operated through simple pin-driven control.
