244 tm ha-2850/883 low power, high slew rate, wideband operational amplifier description the ha-2850/883 is a wideband, high slew rate, operational amplifier featuring superior speed and bandwidth characteristics. it also features trimmed supply current, which minimizes supply current (and thus ac parameter) variation over process and temperature extremes. for exam- ple, the i cc variation over the entire military temperature range is typically less than 0.5ma. bipolar construction, cou- pled with dielectric isolation, delivers outstanding perfor- mance in circuits with closed loop gains 10. the 340v/ s slew rate, and 470mhz gain bandwidth product ensure high performance in video and wideband amplifier designs. differential gain and phase are a low 0.04% and 0.04 degrees, respectively, making the ha-2850/883 ideal for video applications. a full 10v output swing, high open loop gain, and outstanding ac parameters make the ha-2850/883 an excellent choice for data acquisition systems. ordering information part number temperature range package ha1-2850/883 -55 o c to +125 o c 14 lead cerdip ha7-2850/883 -55 o c to +125 o c 8 lead cerdip features ? this circuit is processed in accordance to mil-std- 883 and is fully conformant under the provisions of paragraph 1.2.1. ? low supply current. . . . . . . . . . . . . . . . . . 8.0ma (max) ? low offset voltage . . . . . . . . . . . . . . . . . . .2.0mv (max) ? high slew rate . . . . . . . . . . . . . . . . . . . . . 340v/ s (typ) ? open loop gain . . . . . . . . . . . . . . . . . . . . . 20kv/v (min) ? wide gain-bandwidth (a v 10) . . . . . . . 470mhz (typ) ? input noise voltage at 1khz . . . . . . . . . 11nv/ hz (typ) ? lower power replacement for ha-2540/883, ad840 applications ? pulse and video amplifiers ? wideband amplifiers ? high speed sample-hold circuits ? fast, precise d/a converters july 1994 pinouts ha-2850/883 (cerdip) top view ha-2850/883 (cerdip) top view nc nc v+ nc out 1 2 3 4 5 6 7 14 13 12 11 10 9 8 + nc nc nc -in +in v- nc nc nc - nc v+ out 1 2 3 4 8 7 6 5 + - nc -in +in v- nc spec number 511095-883 fn3595.1 caution: these devices are sensitive to electrostatic discharge; follow proper ic handling procedures. 1-888-intersil or 321-724-7143 | intersil (and design) is a trademark of intersil americas inc. copyright ? intersil americas inc. 2002. all rights reserved
