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. Programmable level shifting
compensates for sensor dc offsets.
The core of the PGA309 is the precision, low-drift, no
1/f noise Front-End PGA (Programmable Gain
Amplifier). The overall gain of the Front-End PGA +
Output Amplifier can be adjusted from 2.7V/V to
1152V/V. The polarity of the inputs can be switched
through the input mux to accommodate sensors with
unknown polarity output. The Fault Monitor circuit
detects and signals sensor burnout, overload, and
system fault conditions.
