General Description

The EL2245C/EL2445C are dual and quad versions of the popular EL2045C. They are high speed, low power, low cost monolithic operational amplifiers built on Elantecs proprietary complementary bipolar process. The EL2245C/EL2445C are gain-of-2 stable and feature a 275V/µs slew rate and 100MHz bandwidth at gain-of-2 while requiring only 5.2mA of supply current per amplifier.

Features

• 100MHz gain-bandwidth at gainof-2

• Gain-of-2 stable

• Low supply current (per amplifier) = 5.2mA at VS = ±15V

• Wide supply range = ±2V to ±18V dual-supply = 2.5V to 36V single-supply

• High slew rate = 275V/µs

• Fast settling = 80ns to 0.1 for a 10V step

• Low differential gain = 0.02 at AV = +2, RL = 150Ω

• Low differential phase = 0.07° at AV = +2, RL = 150Ω

• Stable with unlimited capacitive load

• Wide output voltage swing =±13.6V with VS = ±15V, RL = 1000Ω = 3.8V/0.3V with VS = +5V, RL = 500Ω
