LT1220 45MHz, 250V/m s Operational Amplifier FEATURES DESCRIPTIO n Gain-Bandwidth: 45MHz The LT 1220 is a high speed operational amplifier with n Unity-Gain Stable superior DC performance. The LT1220 features reduced n Slew Rate: 250V/m s input offset voltage, lower input bias currents and higher TM n C-Load Op Amp Drives Capacitive Loads DC gain than devices with comparable bandwidth and slew n Maximum Input Offset Voltage: 1mV rate. The circuit is a single gain stage that includes n Maximum Input Bias Current: 300nA proprietary DC gain enhancement circuitry to obtain pre- n Maximum Input Offset Current: 300nA cision with high speed. The high gain and fast settling time n Minimum Output Swing Into 500W : 12V make the circuit an ideal choice for data acquisition n Minimum DC Gain: 20V/mV, R = 500W systems. The circuit is also capable of driving large L n Settling Time to 0.1%: 75ns, 10V Step capacitive loads which makes it useful in buffer or cable n Settling Time to 0.01%: 95ns, 10V Step driver applications. n Differential Gain: 0.1%, A = 2, R = 150W V L The LT1220 is a member of a family of fast, high perfor- n Differential Phase: 0.2 , A = 2, R = 150W V L mance amplifiers that employ Linear Technology Corporations advanced complementary bipolar process- U ing. For applications with gains of 4 or greater the LT1221 APPLICATIO S can be used, and for gains of 10 or greater the LT1222 can n Wideband Amplifiers be used for increased bandwidth. n Buffers , LTC and LT are registered trademarks of Linear Technology Corporation C-Load is a trademark of Linear Technology Corporation n Active Filters n Video and RF Amplification n Cable Drivers n 8-, 10-, 12-Bit Data Acquisition Systems TYPICAL APPLICATIO Two Op Amp Instrumentation Amplifier Inverter Pulse Response R5 R4 220W 10k R1 R2 10k 1k R3 1k LT1220 + LT1220 V OUT + 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 BW = 450kHz LT1220 TA01 LT1220 TA02 R = R = 1k V = 20V F G IN V = 15V f = 2MHz S 1 U ULT1220 AB OLUEXAI U RAT GS (Note 1) S T I + Total Supply Voltage (V to V ) .............................. 36V Operating Temperature Range Differential Input Voltage ........................................ 6V LT1220C ........................................... 40 C TO 85 C Input Voltage ..........................................................
