EL4452
FN7170
Wideband Variable-Gain Amplifier with Gain of 10
The EL4452 is a complete variablegain 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 ±5V to ±15V and has an analog input range of ±0.5V. AC characteristics do not change appreciably over the supply range. The circuit has an operational temperature of -40°C to +85°C and is packaged in 14-pin PDIP and SO-14. The EL4452 is fabricated with Elantec's proprietary complementary bipolar process which gives excellent signal symmetry and is very rugged.
Features
· Complete variable-gain amplifier complete with output amplifier · Compensated for Gain 10 · 50MHz signal bandwidth · 50MHz gain-control bandwidth · Low 29nV/Hz input noise · Operates on ±5V to ±15V supplies · All inputs are differential · > 70dB attenuation @ 5MHz
Applications
· AGC variable-gain amplifier · IF amplifier · Transducer amplifier

CAUTION: Stresses above those listed in "Absolute Maximum Ratings" may cause permanent damage to the device. This is a stress only rating and operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. IMPORTANT NOTE: All parameters having Min/Max specifications are guaranteed. Typical values are for information purposes only. Unless otherwise noted, all tests are at the specified temperature and are pulsed tests, therefore: TJ = TC = TA
