EL2245C, EL2445C
General Description
The EL2245C/EL2445C are dual and quad versions of the popular EL2045C. They are high speed, low power, low cost monolithic oper-ational amplifiers built on Elantec's proprietary complementary bipolar process. The EL2245C/EL2445C are gain-of-2 stable and fea-ture 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 EL2245C/EL2445C is from ±18V down to as little as ±2V. For single-supply operation, the EL2245C/EL2445C operate from 36V down to as little as 2.5V. The excellent power supply operating range of the EL2245C/EL2445C makes them an obvious choice for applications on a single +5V or +3V supply.
The EL2245C/EL2445C also feature an extremely wide output volt-age swing of ±13.6V with V S = ±15V and R L = 1000Ω. At ±5V,output voltage swing is a wide ±3.8V with R L = 500Ω and ±3.2V with R L = 150Ω. Furthermore, for single-supply operation at +5V, output voltage swing is an excellent 0.3V to 3.8V with R L = 500Ω.
At a gain of +2, the EL2245C/EL2445C have a -3dB bandwidth of 100MHz with a phase margin of 50°. They can drive unlimited load capacitance, and because of their conventional voltage-feedback topology, the EL2245C/EL2445C allow the use of reactive or non-lin-ear elements in their feedback network. This versatility combined with l o w c o s t a n d 75m A o f o u t p u t -c u r r e n t d r i v e m a k e t h e EL2245C/EL2445C an ideal choice for price-sensitive applications requiring low power and high speed.
