NTE1634
Integrated Circuit
Dual Preamp ^w/ALC
Description:
The NTE1634 is a monolithic integrated circuit in a 14–Lead DIP type package consisting of a dual
equalizer amplifier with automatic level control (ALC) and is suitable for stereo radio cassette applications.
Features:
D Dual Equalizer Amplifier with Built–In ALC Circuit.
D Recording Amp Available Because of High Gain Characteristic (Variable Monitor Possible).
D Good Channel Separation (Sep = 50dB Typ)
D Capable of Direct Meter Driving and ALS Transistor.
D Good ALC Response Balance Between Channels.
D Wider Operating Supply Voltage Range (4V to 13V)
Absolute Maximum Ratings: (T_A = +25°C unles otherwise specified)
