Published:2009/6/29 23:52:00 Author:May | From:SeekIC

Using linear and log pots with tone control network in feedback path of CA3140 bipolar MOS opamp, circuit provides 20-dB gain in flat position and ±15dB bass and treble boost and cut at 100 and 10,000 Hz.Output is 25 V P-P at 20 kHz and is -3 dB at 24 kHz from 1-kHz reference. Optional connection for ±15V supply is also shown.- Circuit Ideas for RCA Linear ICs, RCA Solid State Division, Somerville, NJ, 1977, p 10.
