EL2257C/EL2357C  
125 MHz Single Supply, Clamping Op Amps  
Features  
General Description  
• Specified for +3V, +5V, or ± 5V  
Applications  
• Power Down to 0 µA  
• Output Voltage Clamp  
• Large Input Common Mode Range  
0V < VCM < VS - 1.2V  
• Output Swings to Ground Without  
Saturating  
• -3 dB Bandwidth = 125 MHz  
• ± 0.1 dB Bandwidth = 30 MHz  
• Low Supply Current = 5 mA  
• Slew Rate = 275 V/µs  
• Low Offset Voltage = 4 mV max  
• Output Current = ±100 mA  
• High Open Loop Gain = 80 dB  
• Differential Gain = 0.05%  
• Differential Phase = 0.05°  
The EL2257C/EL2357C are supply op amps. Prior single supply op  
amps have generally been limited to bandwidths and slew rates 1/4  
that of the EL2257C/EL2357C. The 125 MHz bandwidth, 275 V/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 appli-  
cations. 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 com-  
pletely to ground without saturating. The outputs can also drive to  
within 1.2V of the top rail. The EL2257C/EL2357C will output  
±100 mA and will operate with single supply voltages as low as 2.7V,  
making them ideal for portable, low power applications.  
The EL2257C/EL2357C have a high speed disable feature. Applying a  
low logic level to all ENABLE pins reduces the supply current to 0 µA  
within 50 ns. Each amplifier has its own ENABLE pin. This is useful  
for both multiplexing and reducing power consumption.  
Applications  
The EL2257C/EL2357C also have an output voltage clamp feature.  
This clamp is a fast recovery (<7 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.  
• Video Amplifier  
• PCMCIA Applications  
• A/D Driver  
• Line Driver  
• Portable Computers  
• High Speed Communications  
• RGB Printer, FAX, Scanner  
Applications  
• Broadcast Equipment  
• Active Filtering  
• Multiplexing  
The EL2257C/EL2357C are available in plastic DIP and SOIC pack-  
ages. Both parts operate over the industrial temperature range of -40°C  
to +85°C. For single amplifier applications, see the  
EL2150C/EL2157C. For space saving, industry standard pin out dual  
and quad applications, see the EL2250C/EL2450C.
