General Description
The EL2045C is a high speed, low power, low cost monolithic
operational amplifier built on Elantec’s proprietary comple-
mentary bipolar process. The EL2045C is gain-of-2 stable and
features a 275 V/ms slew rate and 100 MHz gain-bandwidth
product while requiring only 5.2 mA of supply current.

bined with low cost and 75 mA of output-current drive makes
the EL2045C an ideal choice for price-sensitive applications re-
quiring low power and high speed.
