PGA309-HT - Programmable Sensor Conditioner

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.).

Features

  • 2 Complete Bridge Sensor Conditioner.
  • Voltage Output: Ratiometric or Absolute.
  • Digital Cal: No Potentiometers/Sensor Trims.
  • Sensor Error Compensation.
  • Span, Offset, and Temperature Drifts.
  • Low Error, Time-Stable.
  • Sensor Linearization Circuitry.
  • Temperature Sense: Internal or External.
  • Calibration Lookup Table Logic.
  • Uses External EEPROM (SOT23-5).
  • Over/Under-Scale Limiting.
  • Sensor Fault.
