EL2257
FN7063
125MHz Single Supply, Clamping Op Amp
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.
