Overview
® Data Sheet February 28, 2002 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.
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.
The EL2257 has a high speed disable feature.
Applying a low logic level to all ENABLE pins reduces the supply current to 0µA within 50ns.
Each amplifier has its own ENABLE pin.
This is useful for both multiplexing and reducing power consumption.
The EL2257 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.
The EL2257 is available in 14-pin SO (0.
150") and 14-pin PDIP packages and operates over the industrial temperature range of -40°C to +85°C.
For single amplifier applications, see the EL2150 and EL2157.
For space-saving, industrystandard pinout dual and quad applications, see the EL2250 and EL2450.
