LT1210 1.1A, 35MHz Current Feedback Amplifier FEATURES DESCRIPTION n 1.1A Minimum Output Drive Current The LT 1210 is a current feedback amplifier with high n 35MHz Bandwidth, A = 2, R = 10 output current and excellent large-signal characteristics. V L n 900V/s Slew Rate, A = 2, R = 10 The combination of high slew rate, 1.1A output drive V L n High Input Impedance: 10M and 15V operation enables the device to deliver signifi- n Wide Supply Range: 5V to 15V cant power at frequencies in the 1MHz to 2MHz range. (TO-220 and DD Packages) Short-circuit protection and thermal shutdown ensure n Enhanced SO-16 Package for 5V Operation the devices ruggedness. The LT1210 is stable with large JA n Shutdown Mode: I < 200A capacitive loads, and can easily supply the large currents S n Adjustable Supply Current required by the capacitive loading. A shutdown feature n Stable with C = 10,000pF switches the device into a high impedance and low sup- L n Operating Temperature Range: 40C to 85C ply current mode, reducing dissipation when the device n Available in 7-Lead DD, TO-220 and is not in use. For lower bandwidth applications, the sup- n 16-Lead SO Packages ply current can be reduced with a single external resistor. The LT1210 is available in the TO-220 and DD pack- ages for operation with supplies up to 15V. For 5V APPLICATIONS applications the device is also available in a low thermal n Cable Drivers resistance SO-16 package. n Buffers All registered trademarks and trademarks are the property of their respective owners. n Test Equipment Amplifiers n Video Amplifiers n ADSL Drivers TYPICAL APPLICATION Twisted Pair Driver Total Harmonic Distortion vs Frequency 15V 50 V = 15V S + V = 20V OUT P-P 4.7F* 100nF A = 4 V 60 R T 11 V + IN 70 2.5W LT1210 T1** R = 12.5 L SD R = 10 R L L 80 100 1 3 2.5W R = 50 L 4.7F* 90 100nF 845 15V 100 * TANTALUM 1k 10k 100k 1M ** MIDCOM 671-7783 OR EQUIVALENT FREQUENCY (Hz) 274 1210 TA02 1210 TA01 Rev C 1 Document Feedback For more information www.analog.com TOTAL HARMONIC DISTORTION (dB) +LT1210 (Note 1) ABSOLUTE MAXIMUM RATINGS Supply Voltage ..................................................... 18V Specified Temperature Range (Note 4) Input Current ....................................................... 15mA LT1210C ................................................... 0C to 70C Output Short-Circuit Duration LT1210I ................................................40C to 85C (Note 2) ..........................................Thermally Limited Junction Temperature ........................................ 150C Operating Temperature Range (Note 3) Storage Temperature Range ..................65C to 150C LT1210C ...............................................40C to 85C Lead Temperature (Soldering, 10 sec) ...................300C LT1210I ................................................40C to 85C PIN CONFIGURATION TOP VIEW + + V 1 16 V FRONT VIEW + FRONT VIEW V 2 15 NC 7 OUT 7 OUT OUT 3 14 V 6 V 6 V 5 COMP + + V 4 13 COMP 5 COMP 4 V + 4 V 3 SHUTDOWN NC 5 12 SHUTDOWN SHUTDOWN TAB 3 2 +IN + TAB IS V 2 +IN 1 IN + IN 6 11 +IN IS V 1 IN R PACKAGE NC 7 10 NC T7 PACKAGE 7-LEAD PLASTIC D + + 7-LEAD TO-220 V 8 9 V T = 150C, = 25C/WD JMAX JA T = 150C, = 5C/W JMAX JC S PACKAGE 16-LEAD PLASTIC SO T = 150C, = 40C/W (Note 5) JMAX JA
