The LT1818/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 100Ω load to ±3.8V with ±5V supplies. On a single 5V supply, the output swings from 1V to 4V with a 100Ω 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-Poutput at a gain of 2.The LT1818/LT1819 are manufactured on our advanced low voltage complementary bipolar process. The LT1818 (single op amp) is available in TSOT-23 and SO-8 packages; the LT1819 (dual op amp) is available in MSOP-8 and SO-8 packages.ApplicationsWideband AmplifiersBuffersActive FiltersVideo and RF AmplificationCommunication ReceiversCable DriversData Acquisition Systems

The LT1880 op amp brings high accuracy input performance and rail-to-rail output swing to the SOT-23 package. Input offset voltage is trimmed to less than 150μV and the low drift maintains this accuracy over the operating temperature range. Input bias current is an ultralow 900pA maximum.The amplifier works on any total power supply voltage between 2.7V and 36V (fully specified from 5V to ±15V). Output voltage swings to within 55mV of the negative supply and 250mV of the positive supply, which makes the amplifier a good choice for low voltage single supply operation.Slew rates of 0.4V/μs with a supply current of 1.2mA give superior response and settling time performance in a low power precision amplifier.The LT1880 is available in a 5-lead SOT-23 package.ApplicationsThermocouple AmplifiersBridge Transducer ConditionersInstrumentation AmplifiersBattery-Powered SystemsPhotocurrent Amplifiers

The LT1910 is a high side gate driver that allows the use of low cost N-channel power MOSFETs for high side switching applications. It contains a completely self-contained charge pump to fully enhance an N-channel MOSFET switch with no external components.When the internal drain comparator senses that the switch current has exceeded the preset level, the switch is turned off and a fault flag is asserted. The switch remains off for a period of time set by an external timing capacitor and then automatically attempts to restart. If the fault still exists, this cycle repeats until the fault is removed, thus protecting the MOSFET. The fault flag becomes inactive once the switch restarts successfully.The LT1910 has been specifically designed for harsh operating environments such as industrial, avionics and automotive applications where poor supply regulation and/or transients may be present. The device will not sustain damage from supply transients of –15V to 60V.The LT1910 is available in the SO-8 package.ApplicationsIndustrial ControlAvionics SystemsAutomotive SwitchesStepper Motor and DC Motor ControlElectronic Circuit Breaker
