Intersil Corporation HFA1145 Datasheet

HFA1145
Data Sheet September 1998 File Number 3955.3
330MHz, Low Power, Current Feedback Video Operational Amplifier with Output Disable
This amplifier features a TTL/CMOS compatible disable control, pin 8, which when pulled low reduces the supply current and forces the output into a high impedance state. This allows easy implementation of simple, low power video switching and routing systems. Component and composite video systems also benefit from this op amp’s excellent gain flatness, and good differential gain and phase specifications.
Multiplexed A/D applications will also find the HFA1145 useful as the A/D driver/multiplexer.
The HFA1145 is a low power, high performance upgrade for the CLC410.
For Military grade product, please refer to the HFA1145/883 data sheet.

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.
NOTES:
1. Output is short circuit protectedto ground. Brief short circuits to ground will not degrade reliability, however continuous (100% dutycycle) output current must not exceed 30mA for maximum reliability.
