The EL2250/EL2450 are part of a family of the electronics industry’s fastest single supply op amps available. Prior single supply op amps have generally been limited to bandwidths and slew rates to that of the EL2250/EL2450. 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 EL2250/EL2450 will output ±100mA and will operate with single supply voltages as low as 2.7V, making them ideal for portable, low power applications.

The EL2250/EL2450 are available in PDIP and SO packages in industry standard pinouts. Both parts operate over the industrial temperature range of -40^oC to +85^oC, and are part of a family of single supply op amps. For single amplifier applications, see the EL2150/EL2157. For dual and triple amplifiers with power down and output voltage clamps, see the EL2257/EL2357.
