tl/h/5560 lh0002 buffer february 1995 lh0002 buffer general description the lh0002 is a general purpose buffer. its features make it ideal to integrate with operational amplifiers inside a closed loop configuration to increase current output. the symmetri- cal output portion of the circuit also provides a low output impedance for both the positive and negative slopes of out- put pulses. the lh0002 is available in an 8-lead to-99 can. the lh0002c is available in an 8-lead to-99, and a 10-pin molded dual-in-line package. the lh0002 is specified for operation over the b 55 cto a 125 c military temperature range. the lh0002c is speci- fied for operation over the 0 cto a 85 c temperature range. features y high input impedance 400 k x y low output impedance 6 x y high power efficiency y low harmonic distortion y dc to 30 mhz bandwidth y output voltage swing that approaches supply voltage y 400 ma pulsed output current y slew rate is typically 200 v/ m s y operation from g 5v to g 20v applications y line driver y 30 mhz buffer y high speed d/a conversion schematic and connection diagrams tl/h/5560 1 pin numbers in parentheses denote pin connections for dual-in-line package. dual-in-line package tl/h/5560 2 order number lh0002cn see ns package number n10a metal can package tl/h/5560 3 order number lh0002h, lh0002h-mil or lh0002ch lh0002h/883 * see ns package number h08d * available per smd y 7801301 c 1995 national semiconductor corporation rrd-b30m115/printed in u. s. a.
