Programmable amplifier 2 (PGA2)
This block amplifies (with a programmable gain) the output voltages of PGA1 and of the DAC, following the
equation:
Where:
Gain2 is the gain of the Programmable Amplifier 2
A/D converter (ADC)
This block converts into a digital format the output voltage of PGA2.

Rev 007
PGA2_Out = Gain2 * [ PGA1_Out – DAC_Out ]
PGA1_Out is the differential output voltage of the Programmable Amplifier 1
PGA2_Out is the differential output voltage of the Programmable Amplifier 2
DAC_Out is the differential output voltage of D/A converter
