Product Summary
The PGA308AIDGSR is a programmable analog sensor signal conditioner. The analog signal path amplifies the sensor signal and provides digital calibration for offset and gain. Calibration is done via the 1W pin, a digital One-Wire, UART-compatible interface. For three-terminal sensor modules, 1W may be connected to VOUT and the assembly programmed through the VOUT pin. Gain and offset calibration parameters of PGA308AIDGSR are stored onboard in seven banks of one-time programmable (OTP) memory. The power-on reset (POR) OTP bank may be programmed a total of four times. The applications of the PGA308AIDGSR include Bridge Sensors, Remote 4-20mA Transmitters, Strain, Load, Weigh Scales, Automotive Sensors.
