Description
The LT®1818/LT1819 are single/dual wide bandwidth, high slew rate,low noise and distortion operational amplifiers with excellent DC performance. The LT1818/LT1819 have been designed for wider bandwidth and slew rate, much lower input offset voltage and lower noise and distortion than devices with comparable supply current. The circuit topology is a voltage feedback amplifier with the excellent slewing characteristics of a current feedback amplifier.
The output drives a 100Ohm load to ±3.8V with ±5V supplies. On a single 5V supply, the output swings from 1V to 4V with a 100Ohm load connected to 2.5V. The amplifier is unity-gain stable with a 20pF capacitive load without the need for a series resistor.
Harmonic distortion is –85dBc up to 5MHz for a 2VP-P output at a gain of 2.
The LT1818/LT1819 are manufactured on Linear Technology’s advanced low voltage complementary bipolar process. The LT1818 (single op amp) is available in SOT-23 and SO-8 packages; the LT1819 (dual op amp) is available in MSOP-8 and SO-8 packages.
