set at 10 kΩ (Design # 1). The thermistor was at room temperature. The MCP6S22
PGA was at its default settings, input CH0 and gain = 1. The results using the
PICA2Dlab.hex file (Section 3.2.6 “Choosing Firmware for the Signal Analysis
PICtail Daughter Board”) are shown in Figure 3-7. The output voltage is 2.568V.
