LT1357 25MHz, 600V/s Op Amp FEATURES DESCRIPTION n 25MHz Gain Bandwidth The LT 1357 is a high speed, very high slew rate opera- n 600V/s Slew Rate tional amplifier with outstanding AC and DC performance. n 2.5mA Maximum Supply Current The LT1357 has much lower supply current, lower input n Unity-Gain Stable offset voltage, lower input bias current, and higher DC gain TM n C-Load Op Amp Drives All Capacitive Loads than devices with comparable bandwidth. The circuit n 8nV/Hz Input Noise Voltage topology is a voltage feedback amplifier with the n 600V Maximum Input Offset Voltage slewing characteristics of a current feedback amplifier. n 500nA Maximum Input Bias Current The amplifier is a single gain stage with outstanding n 120nA Maximum Input Offset Current settling characteristics which makes the circuit an ideal n 20V/mV Minimum DC Gain, R =1k choice for data acquisition systems. The output drives a L n 115ns Settling Time to 0.1%, 10V Step 500 load to 12V with 15V supplies and a 150 n 220ns Settling Time to 0.01%, 10V Step load to 2.5V on 5V supplies. The amplifier is also n 12V Minimum Output Swing into 500 stable with any capacitive load which makes it useful in n 2.5V Minimum Output Swing into 150 buffer or cable driver applications. n Specified at 2.5V, 5V, and 15V The LT1357 is a member of a family of fast, high perfor- U mance amplifiers using this unique topology and employ- APPLICATIONS ing Linear Technology Corporations advanced bipolar complementary processing.
