gain of 650 V/V. The thermopile outputs only a few
millivolts when subjected to infrared radiation. The
amplifier is compensated and bandlimited by C1 in
combination with R2.

amplifier with a gain of 768 V/V. The load cell is
excited with +5 V and has a 1 mV/V sensitivity. Its
full scale output signal is amplified to produce a
fully differential ± 3.8 V into the CS5510/12 A/D
converter. This circuit operates from +5 V.
