Description

The EL2270 is a dual current-feedback operational amplifiers which achieves a -3dB bandwidth of 70MHz at a gain of +1 while consuming only 1mA of supply current per amplifier. It will operate with dual supplies ranging from ±1.5V to ±6V, or from single supplies ranging from +3V to +12V. In spite of its low supply current, the EL2270 can output 55mA while swinging to ±4V on ±5V supplies. These attributes make the EL2270 an excellent choice for low power and/or low voltage cable-driver, HDSL, or RGB applications.

For applications where board space is extremely critical. The EL2270 is available in industry standard pinouts in SO package.

For single and dual applications with disable, consider the EL2176 (8-pin single) or EL2276 (14-pin dual). For higher speed applications where power is still a concern, consider the EL2180/EL2186 family which also comes in similar single, dual, triple and quad configurations. The EL2180/EL2186 family provides a -3dB bandwidth of 250MHz while consuming 3mA of supply current per amplifier.

Applications

• Low power/battery applications
• HDSL amplifiers
• Video amplifiers
• Cable drivers
• RGB amplifiers
• Test equipment amplifiers
• Current to voltage converters
