DescriptionThe EL2150C/EL2157C 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 (/4 that of the EL2150C/EL2157C. The 125 MHz bandwidth, 275 V/ms 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 EL2150C/EL2157C will output g100 mA and will operate with single supply voltages as low as 2.7V, making it ideal for portable, low power applications. The EL2157C has a high speed disable feature. Applying a low logic level to this pin reduces the supply current to 0 mA within 50 ns. This is useful for both multiplexing and reducing power consumption.
The EL2157C also has an output voltage clamp feature. This clamp is a fast recovery (k7 ns) output clamp that prevents the output voltage from going above the preset clamp voltage. This feature is desirable for A/D applications, as A/D converters can require long times to recover if overdriven.
For applications where board space is critical the EL2150C is available in the tiny 5 lead SOT23 package, which has a footprint 28% the size of an 8 lead SOIC. The EL2150C/EL2157C are also both available in 8 pin plastic DIP and SOIC packages. All parts operate over the industrial temperature range of b40§C to a85§C. For dual, triple, or quad applications, contact the factory.
