LT1357 25MHz, 600V/µs Op Amp FEATURES s s s s s s s s s s s s s s s DESCRIPTION The LT ®1357 is a high speed, very high slew rate operational amplifier with outstanding AC and DC performance. The LT1357 has much lower supply current, lower input offset voltage, lower input bias current, and higher DC gain than devices with comparable bandwidth. The circuit topology is a voltage feedback amplifier with the slewing characteristics of a current feedback amplifier. The amplifier is a single gain stage with outstanding settling characteristics which makes the circuit an ideal choice for data acquisition systems. The output drives a 500Ω load to ±12V with ±15V supplies and a 150Ω load to ± 2.5V on ±5V supplies. The amplifier is also stable with any capacitive load which makes it useful in buffer or cable driver applications. The LT1357 is a member of a family of fast, high performance amplifiers using this unique topology and employing Linear Technology Corporation’s advanced bipolar complementary processing. For dual and quad amplifier versions of the LT1357 see the LT1358/LT1359 data sheet. For higher bandwidth devices with higher supply current see the LT1360 through LT1365 data sheets. For lower supply current amplifiers see the LT1354 and LT1355/ LT1356 data sheets. Singles, duals, and quads of each amplifier are available. 25MHz Gain Bandwidth 600V/µs Slew Rate 2.5mA Maximum Supply Current Unity-Gain Stable C-LoadTM Op Amp Drives All Capacitive Loads 8nV/√Hz Input Noise Voltage 600µV Maximum Input Offset Voltage 500nA Maximum Input Bias Current 120nA Maximum Input Offset Current 20V/mV Minimum DC Gain, RL=1k 115ns Settling Time to 0.1%, 10V Step 220ns Settling Time to 0.01%, 10V Step ±12V Minimum Output Swing into 500Ω ±2.5V Minimum Output Swing into 150Ω Specified at ± 2.5V, ± 5V, and ±15V U APPLICATIONS s s s s s Wideband Amplifiers Buffers Active Filters Data Acquisition Systems Photodiode Amplifiers , LTC and LT are registered trademarks of Linear Technology Corporation.
