EL2150C�EL2157C is a 125MHz single supply�clamping op amps, which has the following features: 1) voltage range is 3V�a5V�or g5V; 2) low power consumption (0mA); 3) output voltage clamp; 4) large input common mode range (0V~Vs-1.2V); 5) output swing can reach ground; 6) low input offset voltage (2mV); 7) high open loop gain (80dB); 8) low supply current (5mA); 9) high slew rate (275V/µs); 10) high output current (g100mA); 11) differential gain accuracy is 0.05% and differential phase accuracy is 0.05°.
The Elantec EL2150C/EL2157C are described as the industry's fastest single supply op amps available. These devices offer a 125 MHz bandwidth, a slew rate of 275 V/µs, and low offset voltage, making them ideal for video speed applications such as PCMCIA interfaces, A/D drivers, and RGB systems.
The EL2150C is available in 8-pin PDIP/SOIC packages or a compact 5-lead SOT23 package. The EL2157C variant includes additional features: a high-speed disable function that reduces supply current to zero within 50 ns, and an output voltage clamp feature with fast recovery (<7 ns) to prevent overdrive issues in A/D applications.
