NTE1439
Integrated Circuit
Dual Attenuator
Description:
The NTE1439 is an integrated circuit in a 14–Lead DIP type package which logarithmically controls
the throughput (gain) of an audio signal by the DC voltage or resistance value and has 2 circuits. Since
voltage is internally stabilized, the stable operations are assured at the allowable supply voltage range
(8V to 14.4V). The current source is provided with control circuit so that operation can be controlled
by the voltage drop. This device is used for electronic volume control in radio, television, stereo, tape
recorder, an transceiver applications.
Features:
D Wide Operating Voltage Range
D High Attenuation Level
D Easy to Control Signal Gain with a Simple Circuit
D Less Crosstalk Between Each Channel
Absolute Maximum Ratings: (TA = +25°C unless otherwise specified)

Note 1. DC voltage must not be applied to Pin1, Pin2, Pin8, and Pin9 from the outside. 6V is used
as voltage for V6 and V13 and no larger than VCC voltage.
