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/s 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 VS = ±15V and RL = 1000. 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 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
low cost and 75mA of output-current drive make the
EL2245C/EL2445C an ideal choice for price-sensitive applications
requiring low power and high speed.
