1 ? HA-2620, ha-2625 100mhz, high input impedance, very wideband, uncompensated operational amplifiers HA-2620/2625 are bipolar operatio nal amplifiers that feature very high input impedance (500m ? , HA-2620) coupled with wideband ac performance. the high resistance of the input stage is complemented by low offset voltage (0.5mv, HA-2620) and low bias and offs et current (1na, HA-2620) to facilitate accurate signal processing. input offset can be reduced further by means of an external nulling potentiometer. the 100mhz gain bandwidth product (HA-2620/2625 are stable for cl osed loop gains greater than 5), 35v/ s slew rate and 150kv/v open loop gain enables HA-2620/2625 to perform high gai n amplification of very fast, wideband signals. these dynamic characteristics, coupled with fast settling times, make these amplifiers ideally suited to pulse amplification designs as well as high frequency (e.g., video) applications. the frequency response of the amplifier can be tailored to exact design requirements by means of an external bandwidth control capacitor connected from the comp pin to gnd. in addition to its application in pulse and video amplifier designs, HA-2620/2625 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. for more information, please refer to application notes an509, an519 and an546. ordering information features ? gain bandwidth product (a v 5). . . . . . . . . . . . . 100mhz ? 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. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 35v/ s ? output short circuit protection ? compensation pin for unity gain capability applications ? video and rf amplifier ? pulse amplifier ? audio amplifiers and filters ? high-q active filters ? high speed comparators ? low distortion oscillator pinout ha-2625 (pdip, soic) top view HA-2620 (metal can) top view part number (brand) temp. range ( o c) package pkg. dwg. # ha2-2620-2 -55 to 125 8 pin metal can t8.c ha3-2625-5 0 to 75 8 ld pdip e8.3 ha9p2625-9 (h26259) -40 to 85 8 ld soic m8.15 1 2 3 4 8 7 6 5 + bal -in +in v- comp v+ out bal - comp out -in bal +in v+ bal 2 4 6 1 3 7 5 8 + v- - data sheet june 2003 fn2903.6 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. 2003. all rights reserved. all other trademarks mentioned are the property of their respective owners.
