HA7-2842883

HA-2842/883 July 1994 Wideband, High Slew Rate, High Output Current, Video Operational Amplifier Description The HA-2842/883 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-2842/883 are ideally suited for high speed cable driver circuits, where low closed loop gains and 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-2842/883 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 average ICC variation from +85oC to -40oC is <600µA (±2%),while the standard deviation of the ICC 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.
