LT1818/LT1819 400MHz, 2500V/s, 9mA Single/Dual Operational Ampli ers FEATURES DESCRIPTION n 400MHz Gain Bandwidth Product The LT 1818/LT1819 are single/dual wide bandwidth, high n 2500V/s Slew Rate slew rate, low noise and distortion operational ampli ers n 85dBc Distortion at 5MHz with excellent DC performance. The LT1818/LT1819 have n 9mA Supply Current Per Ampli er been designed for wider bandwidth and slew rate, much n 6nV/Hz Input Noise Voltage lower input offset voltage and lower noise and distortion n Unity-Gain Stable than devices with comparable supply current. The circuit n 1.5mV Maximum Input Offset Voltage topology is a voltage feedback ampli er with the excellent n 8A Maximum Input Bias Current slewing characteristics of a current feedback ampli er. n 800nA Maximum Input Offset Current The output drives a 100 load to 3.8V with 5V sup- n 40mA Minimum Output Current, V = 3V OUT plies. On a single 5V supply, the output swings from 1V n 3.5V Minimum Input CMR, V = 5V S to 4V with a 100 load connected to 2.5V. The ampli er n Speci ed at 5V, Single 5V Supplies is unity-gain stable with a 20pF capacitive load without the n Operating Temperature Range: 40C to 85C need for a series resistor. Harmonic distortion is 85dBc n Low Pro le (1mm) TSOT-23 (ThinSOT) Package up to 5MHz for a 2V output at a gain of 2. P-P APPLICATIONS The LT1818/LT1819 are manufactured on Linear Tech- nologys advanced low voltage complementary bipolar n Wideband Ampli ers process. The LT1818 (single op amp) is available in n Buffers TSOT-23 and SO-8 packages the LT1819 (dual op amp) n Active Filters is available in MSOP-8 and SO-8 packages. n Video and RF Ampli cation L, LT, LTC, LTM, Linear Technology and the Linear logo are registered trademarks of Linear n Communication Receivers Technology Corporation.
