产品概述
The PGA308AIDGST is a single supply auto-zero Sensor Amplifier for use with 4 to 20mA remote transmitters. 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 are stored on board 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 all-analog signal path contains a 2x2 input multiplexer (MUX) to allow electronic sensor lead swapping, a coarse offset adjust, an auto-zero programmable gain instrumentation amplifier (PGA), a fine gain adjust, a fine offset adjust and a programmable gain output amplifier. Fault monitor circuitry detects and signals sensor burnout, overload and system fault conditions.
