EL4452: Wideband Variable-Gain Amplifier with Gain of 10

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 ±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.
