DESCRIPTION

· The LT1818/LT1819 are single/dual wide bandwidth, high slew rate, low noise and distortion operational amplifiers with excellent DC performance.

· Designed for wider bandwidth and slew rate, lower input offset voltage, and reduced noise and distortion compared to devices with similar supply current.

· Voltage feedback amplifier topology with current feedback amplifier slewing characteristics.

· Output drives a 100Ω load to ±3.8V with ±5V supplies; on a single 5V supply, output swings from 1V to 4V with a 100Ω load connected to 2.5V.

· Unity-gain stable with a 20pF capacitive load without a series resistor.

· Harmonic distortion is –85dBc up to 5MHz for a 2V P-P output at a gain of 2.

· Manufactured on Linear Technology’s advanced low voltage complementary bipolar process.

· LT1818 available in TSOT-23 and SO-8 packages; LT1819 available in MSOP-8 and SO-8 packages.
