HFA1205

September 1998 File Number 3605.5

Dual, 400MHz, Low Power, Video Operational Ampliﬁer

The HFA1205 is a dual, high speed, low power current feedback ampliﬁer built with Intersil’s proprietary complementary bipolar UHF-1 process.

These ampliﬁers deliver 400MHz bandwidth and 1275V/µs slew rate, on only 60mW of quiescent power. They are speciﬁcally designed to meet the performance, power, and cost requirements of high volume video applications. The excellent gain ﬂatness and differential gain/phase performance make these ampliﬁers well suited for component or composite video applications. Video performance is maintained even when driving a back terminated cable (R when driving two back terminated cables (R

= 150Ω), and degrades only slightly

=75Ω). RGB

applications will beneﬁt from the high slew rates, and high full power bandwidth.

The HFA1205 is a pin compatible, low power, high performance upgrade for the popular Intersil HA5023. For a dual ampliﬁer with output disable capability, please see the HFA1245 datasheet.

CAUTION: Stresses above those listed in “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress only rating and operationofthe device at these or any other conditions above those indicated in the operational sections of this speciﬁcation is not implied.

NOTES:

1. θJA is measured with the component mounted on an evaluation PC board in free air.

2. Output is short circuit protected to ground. Brief short circuits to ground will not degrade reliability, however continuous (100% duty cycle) output current must not exceed 30mA for maximum reliability.
