1 ? HA-2600 12mhz, high input impe dance operational amplifier HA-2600 is an internally compensated bipolar operational amplifier that features ve ry high input impedance (500m ?) coupled with wideband ac performance. the high resistance of the input stage is complemented by low offset voltage (0.5mv) and low bias and offset current (1na) to facilitate accurate signal processing. input offset can be reduced further by means of an external nulling potentiometer. 12mhz unity gain-bandwidth, 7v/ s slew rate and 150kv/v open-loop gain enables the HA-2600 to perform high-gain amplification of fast, wideband signals. these dynamic characteristics, coupled with fast settling times, make this amplifier ideally suited to pulse amplification designs as well as high frequency (e.g. video) applications. the frequency respon se of the amplifier can be tailored to exact design requirements by means of an external bandwidth control capacitor. in addition to its application in pulse and video amplifier designs, the HA-2600 is particularly suited to other high performance designs such as high-gain low distortion audio amplifiers, high-q and wideband active filters and high- speed comparators. features ? bandwidth . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 12mhz ? high input impedance . . . . . . . . . . . . . . . . . . . . . 500m ? ? low input bias current. . . . . . . . . . . . . . . . . . . . . . . . 1na ? low input offset current . . . . . . . . . . . . . . . . . . . . . . 1na ? low input offset voltage . . . . . . . . . . . . . . . . . . . . 0.5mv ? high gain . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 150kv/v ? slew rate. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 7v/ s ? output short circuit protection ? unity gain stable applications ? video amplifier ? pulse amplifier ? audio amplifiers and filters ? high-q active filters ? high-speed comparators ? low distortion oscillators pinout HA-2600 (metal can) top view ordering information part number temp. range ( o c) package pkg. dwg. # ha2-2600-2 -55 to 125 8 pin metal can t8.c comp out -in bal +in v+ bal 2 4 6 1 3 7 5 8 + v- - august 2003 fn2902.5 caution: these devices are sensitive to electrosta tic discharge; follow proper ic handling procedures. 1-888-intersil or 321-724-7143 | intersil (and design) is a registered trademark of intersil americas inc. copyright ? intersil americas inc. 2002. all rights reserved data sheet
