Application Notes
- PGA309 Microcontroller ApplicationPDF, 58 Kb, File published: Jun 7, 2005
The PGA309 programmable gain amplifier can be used with an external microcontroller. In this type of application, the PGA309 becomes a programmable sensor signal conditioner block that also measures temperature. One key feature of the PGA309 reviewed in this report is the test pin. This document then discusses two general applications for the PGA309 with an external microcontroller. - PGA309 Quick Start System Reference Guide (Rev.

PGA309 Quick Start System Reference Guide - Practical Technique for Minimizing the Number of Measurements in Sensor SignalPDF, 155 Kb, File published: Jun 28, 2005
The output of many modern bridge type sensors contains errors that must be eliminated through calibration. One major source of error is variation of sensor span and offset from device to device and their respective drifts with temperature. These drifts can be non-linear. Another source of error is the nonlinearity of the sensor output with applied stimulus. Signal conditioning electronics can also - PGA309 Noise Filtering (Rev. A)PDF, 704 Kb, Revision: A, File published: Nov 28, 2005
The PGA309 programmable gain amplifier generates three primary types of noise: broadband noise, noise from the instrumentation amplifier auto-zero circuit, and noise from the Coarse Offset auto-zero circuit. Noise at the PGA309 output can be reduced by limiting the bandwidth with a simple filter. This application note describes how to select the filter components in order to get the desired bandwi - Ratiometric measurement in the context of LVDT-sensor signal conditioningPDF, 228 Kb, File published: Jul 21, 2016
