EL4452C
Wideband Variable-Gain Amplifier with Gain of 10
Features
Complete variable-gain amplifier complete with output amplifier Compensated for Gain t 10 50 MHz signal bandwidth 50 MHz gain-control bandwidth Low 29 nV SHz input noise Operates on g 5V to g 15V supplies All inputs are differential l 70 dB attenuation 5 MHz
General Description
The EL4452 is a complete variable-gain circuit It offers wide bandwidth and excellent linearity while including a powerful output voltage amplifier drawing modest current The higher gain and lower input noise makes the EL4452 ideal for use in AGC systems The EL4452 operates on g 5V to g 15V and has an analog input range of g 0 5V AC characteristics do not change appreciably over the supply range The circuit has an operational temperature of b 40 C to a 85 C and is packaged in 14-pin P-DIP and SO-14 The EL4452 is fabricated with Elantec’s proprietary complementary bipolar process which gives excellent signal symmetry and is very rugged
Applications
AGC variable-gain amplifier IF amplifier Transducer amplifier
