PGA302 Sensor Signal Conditioners

Texas Instruments PGA302 Sensor Signal Conditioners with 0V-to-5V Ratiometric Output exhibit low drift and noise with both analog and digital features. The device creates 2.5V bridge excitation along with a current output source with programmable current output up to 1mA. Two identical analog front-end (AFE) channels followed by a 16-bit Sigma-Delta ADC are available at the input. Additionally, each AFE channel has a dedicated programmable gain amplifier with a gain of up to 200 V/V. The Texas Instruments PGA302 Sensor Signal Conditioners offer various sensing element types, including piezoresistive, ceramic film, strain gauge, and steel membrane. Other features include memory built-in self-test (MBIST), watchdog timer, and power management control.
