125MHz Single Supply, Clamping Op Amps
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 ¼ 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. The EL2157 also has an output voltage clamp feature. This clamp is a fast recovery (<7ns) 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 EL2150 is available in the tiny 5-pin SOT-23 package, which has a footprint 28% the size of an 8-pin SO. The EL2150 and EL2157 are also both available in 8-pin plastic DIP and SO packages. All parts operate over the industrial temperature range of -40°C to +85°C. For dual, triple, or quad applications, contact the factory.

CAUTION: Stresses above those listed in "Absolute Maximum Ratings" may cause permanent damage to the device. This is a stress only rating and operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. IMPORTANT NOTE: All parameters having Min/Max specifications are guaranteed. Typical values are for information purposes only. Unless otherwise noted, all tests are at the specified temperature and are pulsed tests, therefore: TJ = TC = TA

1. CLAMP pin and ENABLE pin specifications apply only to the EL2157. 2. Internal short circuit protection circuitry has been built into the EL2150/EL2157. See the Applications section. 3. If the disable feature is not desired, tie the ENABLE pin to the VS pin, or apply a logic high level to the ENABLE pin. 4. The maximum output voltage that can be clamped is limited to the maximum positive output Voltage, or VOP. Applying a voltage higher than VOP inactivates the clamp. If the clamp feature is not desired, either tie the CLAMP pin to the VS pin, or simply let the CLAMP pin float.
