Data Sheet September 1998 File Number 2766.5

80MHz, High Slew Rate, High Output Current, Video Operational Ampliﬁer

The HA-2842 is a wideband, high slew rate, operational ampliﬁer featuring an outstanding combination of speed, bandwidth, and output drive capability. This ampliﬁer’s performance is further enhanced through stable operation down to closed loop gains of +2, the inclusion of offset null controls, and by its excellent video performance.

The capabilities of the HA-2842 are ideally suited for high speed cable driver circuits, where lowclosedloopgainsand high output drive are required. With a 6MHz full power bandwidth, this ampliﬁer is well suited for high frequency signal conditioning circuits and video ampliﬁers. Gain ﬂatness of 0.035dB, combined with differential gain and phase speciﬁcations of 0.02%, and 0.03 degrees, respectively, make the HA-2842 ideal for component and composite video applications.

A zener/nichrome based reference circuit, coupled with advanced laser trimming techniques, yields a supply current with a low temperature coefficient and low lot-to-lot variability. For example, the aver ageI <600µA (±2%), while the standard deviation of the I

variation from 85oCto-40oCis

distribution is <0.1mA (0.8%) at 25oC. Tighter ICC control translates to more consistent AC parameters ensuring that units from each lot perform the same way,and easing the task of designing systems for wide temperature ranges. Critical AC parameters, Slew Rate and Bandwidth, each vary by less than ±5% over the industrial temperature range (see Typical Perf ormance Curves).

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. Maximum power dissipation, including output load, must be designed to maintain the maximum junction temperature below 150oC for plastic packages. By using Application Note AN556 on Safe Operating Area equations, along with the packaging thermal resistances listed in the Thermal Information section, proper load conditions can be determined.

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

3. VO=±5V,RLUnconnected,Dutycycle ≤ 50%. For information about usinghighoutputcurrent amplifiers, please refer to Application NoteAN556 (Thermal Safe-Operating-Areas For High Current Op Amps), and the “Power Dissipation Considerations” section in the “ApplicationInformation” section of this datasheet.

4. Maximum continuous (100% Duty Cycle) output current is 50mA. For currents >50mA, Duty Cycle must be derated accordingly.
