125MHz Single Supply, Clamping Op
Amps
Features
• Specified for 3V, 5V, or ±5V applications
• Power-down to 0µA (EL2157)
The EL2150 and EL2157 are the
electronics industry's fastest single
supply op amps available. Prior single
• Output voltage clamp (EL2157)
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.

• Output swings to ground without saturating
• -3dB bandwidth = 125MHz
• ±0.1dB bandwidth = 30MHz
• Low supply current = 5mA
• Slew rate = 275V/µs
• Low offset voltage = 2mV max (SO package)
• Output current = ±100mA
• High open loop gain = 80dB
• Diff gain/phase = 0.05%/0.05°
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.
Applications
• Video amplifiers
• PCMCIA applications
• A/D drivers
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.
• Line drivers
• Portable computers
• High speed communications
• RGB applications
• Broadcast equipment
• Active filtering
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 both available in an 8-pin SO package. All parts
operate over the industrial temperature range of -40°C to
+85°C. For dual, triple, or quad applications, contact the
factory.
