CA3080A operational transconductance amplifier uses bridge to provide automat;c temperature com-pensation of gain that is controlled by voltage between 0 and +10V applied to op amp A3. With values shown, input and output signal-handling range is ±10 V. Once balanced, circuit provides linear gain control up to four decades.-W.G.Jung, IC Op Amp Cookbook, Howard W.Sams, Indianapolis, IN, 1974, p 455-456.
