EL2150, EL2157 pdf datasheet (

The EL2150 and EL2157 are the
electronics industry's fastest single
supply op amps available. Prior single
supply op amps have generally been limited to bandwidths
and slew rates ? that of the EL2150 and EL2157. The
125MHz bandwidth, 275V/μs slew rate, and 0.05%/0.05°
differential gain/differential phase makes this part ideal for
single or dual supply video speed applications. With its
voltage feedback architecture, these amplifiers can accept
reactive feedback networks, allowing them to be used in
analog filtering applications. The inputs can sense signals
below the bottom supply rail and as high as 1.2V below the
top rail. Connecting the load resistor to ground and operating
from a single supply, the outputs swing completely to ground
without saturating. The outputs can also drive to within 1.2V
of the top rail. The EL2150 and EL2157 will output ±100mA
and will operate with single supply voltages as low as 2.7V,
making them ideal for portable, low power applications.
The EL2157 has a high speed disable feature. Applying a
low logic level to this pin reduces the supply current to 0μA
within 50ns. This is useful for both multiplexing and reducing
power consumption.
