Dual/Quad Low-Power 100MHz Gain-of-2 Stable Op Amp
The EL2245 and EL2445 are dual and quad versions of the popular EL2045. They are high speed, low power, low cost monolithic operational amplifiers built on Elantec's proprietary complementary bipolar process. The EL2245 and EL2445 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. The power supply operating range of the EL2245 and EL2445 is from ±18V down to as little as ±2V. For singlesupply operation, the EL2245 and EL2445 operate from 36V down to as little as 2.5V. The excellent power supply operating range of the EL2245 and EL2445 makes them an obvious choice for applications on a single +5V or +3V supply. The EL2245 and EL2445 also feature an extremely wide output voltage swing of ±13.6V with VS = ±15V and RL = 1k. At ±5V, output voltage swing is a wide ±3.8V with RL = 500 and ±3.2V with RL = 150. Furthermore, for single-supply operation at +5V, output voltage swing is an excellent 0.3V to 3.8V with RL = 500. At a gain of +2, the EL2245 and EL2445 have a -3dB bandwidth of 100MHz with a phase margin of 50°. Because of their conventional voltage-feedback topology, the EL2245 and EL2445 allow the use of reactive or non-linear elements in their feedback network. This versatility combined with low cost and 75mA of output-current drive make the EL2245 and EL2445 an ideal choice for price-sensitive applications requiring low power and high speed.

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.

Slew rate is measured on rising edge. 2. For VS = ±15V, VOUT = 20VPP. For VS = ±5V, VOUT = 5VPP. Full-power bandwidth is based on slew rate measurement using: FPBW = SR/(2 * Vpeak). 3. Video performance measured at VS = ±15V, AV = +2 with 2 times normal video level across RL = 150. This corresponds to standard video levels across a back-terminated 75 load.
