Test Circuit
LC89950
Notes: 1. Adjust VR (2 kΩ) so that the output amplitudes when SW3 is set to the a and b positions are equal.
2. LPF is a 2-MHz low-pass filter. Use a filter with an attenuation of –60 dB at 4 MHz.
3. The operational amplifier (AD842JN) is a non-inverting amplifier, and the gain from the SW1 output to the operational amplifier output should be 0 dB.
