The EL2257 is a single supply op amp.
Prior single supply op amps have
generally been limited to bandwidths
and slew rates one-fourth of that of the EL2257. 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, this amplifier 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 EL2257 will output ±100mA and will
operate with single supply voltages as low as 2.7V, making
them ideal for portable, low power applications.
