Description

The PGA309 is a programmable analog signal conditioner designed for bridge sensors. The analog signal path amplifies the sensor signal and provides digital calibration for zero, span, zero drift, span drift, and sensor linearization errors with applied stress (pressure, strain, etc.). The calibration is done via a One-Wire digital serial interface or through a Two-Wire industry-standard connection. The calibration parameters are stored in external nonvolatile memory (typically SOT23-5) to eliminate manual trimming and achieve long-term stability.

The all-analog signal path contains a 2x2 input multiplexer (mux), auto-zero programmable-gain instrumentation amplifier, linearization circuit, voltage reference, internal oscillator, control logic, and an output amplifier.
