A Precise Amplifier for Digitally Synthesized Source

• Abstract:

  A precise power amplifier is described in the paper. It was designed to amplify the output ac voltage of a digitally synthesized source from 5 V to 5, 10, 20, 30 or 50 V in 0… 1 kHz frequency range. The five voltage gain coefficients may be selected by GPIB and RS-232 interfaces or from the keyboard. The main application of the amplifier is the ac-dc voltage calibration system, especially useful for evaluation of thermal converters at low frequencies.
