PGA970 LVDT Sensor Signal Conditioner

Texas Instruments PGA970 LVDT Sensor Signal Conditioner is a highly integrated system-on-chip LVDT sensor-signal conditioner with advanced signal-processing capabilities. The PGA970 contains a three-channel, low-noise, programmable-gain, analog front end that allows direct connection to the sensing element, followed by three independent 24-bit delta-sigma ADCs. The Texas Instruments PGA970 also contains a digital signal-demodulation block that interfaces to an integrated Arm®-Cortex® M0 MCU, allowing custom sensor-compensation algorithms to be implemented in the device's non-volatile memory. External system communication is achieved using SPI, OWI, GPIO, or PWM digital interfaces. The analog output is supported through a 14-bit DAC and programmable-gain amplifier offering reference or absolute-voltage output. Sensing-element excitation is achieved by using an integrated waveform generator and waveform amplifier. The waveform signal data is user-defined and stored in a designated RAM memory area.
