Internal feedback provides wide bandwidth, low phase distortion, and excellent gain stability. Variable gain
based on signal summation provides large AGC control over a wide bandwidth with low harmonic distortion.
Emitter-follower outputs enable the device to drive capacitive loads. All stages are current-source biased to
obtain high common-mode and supply-voltage rejection ratios. The gain may be electronically attenuated by
applying a control voltage to the AGC pin. No external compensation components are required.
This device is particularly useful in TV and radio IF and RF AGC circuits, as well as magnetic-tape and disk-file
systems where AGC is needed. Other applications include video and pulse amplifiers where a large AGC range,
wide bandwidth, low phase shift, and excellent gain stability are required.
The TL026C is characterized for operation from 0°C to 70°C.

Stresses beyond those listed under absolute maximum ratings may cause permanent damage to the device. This is a stress rating only, and
functional operation of the device at these or any other conditions beyond those indicated in the recommended operating conditions section of
this specification is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTE 1: All voltages are with respect to the midpoint of VCC+ and VCC except differential input and output voltages.
