Product Description

The EL5134, EL5135, EL5234 and EL5235 are voltage

feedback operational amplifiers designed for communication

and imaging applications requiring very low voltage and

current noise. They also feature low distortion while drawing

moderately low supply current and is built on Intersil's

proprietary high-speed complementary bipolar process. The

EL5134, EL5135, EL5234 and EL5235 use a classical

voltage-feedback topology which allows them to be used in a

variety of applications where current-feedback amplifiers are

not appropriate because of restrictions placed upon the

feedback element used with the amplifier.

Gain-Bandwidth Product and the -3dB Bandwidth

The EL5134, EL5135, EL5234 and EL5235 have a gain-

bandwidth product of 1500MHz while using only 6.7mA of

supply current per amplifier. For gains greater than 5 their

closed-loop -3dB bandwidth is approximately equal to the

gain-bandwidth product divided by the noise gain of the

circuit. For gains of 5, higher-order poles in the amplifiers'
