LT1352/LT1353 Dual and Quad 250A, 3MHz, 200V/s Operational Amplifiers DESCRIPTIO FEATURES n 3MHz Gain Bandwidth The LT 1352/LT1353 are dual and quad, very low power, n 200V/s Slew Rate high speed operational amplifiers with outstanding AC n 250A Supply Current per Amplifier and DC performance. The amplifiers feature much lower TM n C-Load Op Amp Drives All Capacitive Loads supply current and higher slew rate than devices with n Unity-Gain Stable comparable bandwidth. The circuit combines the slewing n Maximum Input Offset Voltage: 600V performance of a current feedback amplifier in a true n Maximum Input Bias Current: 50nA operational amplifier with matched high impedance n Maximum Input Offset Current: 15nA inputs. The high slew rate ensures that the large-signal n Minimum DC Gain, R = 2k: 30V/mV bandwidth is not degraded. Each output is capable of L n Input Noise Voltage: 14nV/Hz driving a 1k load to 13V with 15V supplies and a 500 n Settling Time to 0.1%, 10V Step: 700ns load to 3.4V on 5V supplies. n Settling Time to 0.01%, 10V Step: 1.25s The LT1352/LT1353 are members of a family of fast, high n Minimum Output Swing into 1k: 13V performance amplifiers using this unique topology and n Minimum Output Swing into 500: 3.4V employing Linear Technology Corporations advanced n Specified at 2.5V, 5V and 15V complementary bipolar processing. For higher bandwidth n Available in SO-8 Package devices with higher supply current see the LT1354 through n LT1353 in Narrow Surface Mount Package LT1365 data sheets. Bandwidths of 12MHz, 25MHz, 50MHz U and 70MHz are available with 1mA, 2mA, 4mA and 6mA of APPLICATIO S supply current per amplifier. Singles, duals and quads of each amplifier are available. The LT1352 is available in an n Battery-Powered Systems 8-lead SO package. The LT1353 is offered in a 14-lead n Wideband Amplifiers narrow surface mount package. n Buffers , LTC and LT are registered trademarks of Linear Technology Corporation. n Active Filters C-Load is a trademark of Linear Technology Corporation. n Data Acquisition Systems n Photodiode Amplifiers TYPICAL APPLICATIO Instrumentation Amplifier Large-Signal Response R1 R2 R5 R4 50k 5k 1.1k 50k R3 5k 1/2 LT1352 1/2 V + OUT LT1352 V IN + + GAIN = R4/R3 1 + (1/2)(R2/R1 + R3/R4) + (R2 + R3)/R5 = 102 TRIM R5 FOR GAIN TRIM R1 FOR COMMON MODE REJECTION 1352/53 TA01 A = 1 1352/53 TA02 BW = 30kHz V 13523fa 1 U ULT1352/LT1353 ABSOLUTE MAXIMUM RATINGS (Note 1) + Total Supply Voltage (V to V ) .............................. 36V Specified Temperature Range (Note 7) .. 40C to 85C Differential Input Voltage (Transient Only, Note 2) 10V Maximum Junction Temperature (See Below) Input Voltage ..........................................................
