System Reference Guide

1. Offset and Span: Generates the bridge output voltages.

2. Diode Vo: Generates the temperature sensor output voltages for the diode

method.

3. Rt-: Generates the temperature sensor voltages for the Rt-method.

4. Rt+: Generates the temperature sensor voltages for the Rt-method.

5. PGA309_Error: Allows you to read the PGA309 via the ADS1100.

If the raw output of the sensor is not known, the generate_emu_values.xls

spreadsheet (SBOC065, available for download at www.ti.com) can be used to

translate the specifications of your bridge sensor and temperature sensor to system

voltage levels. The spreadsheet contains five sections:
