LT1812IS6#TRMPBF

Instrumentation, Op Amps, Buffer Amps Overview

The LT1812IS6#TRMPBF is a single-channel high-speed operational amplifier manufactured by Analog Devices Inc. It features a gain bandwidth product of 100 MHz and a slew rate of 750 V/µs. The device operates on supply voltages ranging from ±2 V to ±6.3 V (total 4 V to 12.6 V). Key electrical parameters include a maximum input offset voltage of 3 mV, an input bias current of ±6 µA, and an input noise voltage density of 8 nV/√Hz at 10 kHz. It provides a minimum output current of 30 mA and includes a shutdown pin that reduces supply current to approximately 50 µA. The component is housed in a 6-lead plastic TSOT-23 package.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Video and RF amplification
• Cable drivers
• Active filters

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix IS6 corresponds to the 6-lead TSOT-23 package and the extended temperature range (-40°C to +85°C) before ordering. Confirm that the tape and reel packaging matches production requirements. Ensure the application circuit respects the absolute maximum ratings, particularly regarding total supply voltage limits and thermal dissipation constraints within the small outline package.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a balance between low power consumption and high speed is required. The inclusion of a shutdown pin makes it suitable for battery-powered systems where standby power must be minimized. Consider the 100 MHz bandwidth and 750 V/µs slew rate for applications requiring fast transient response without the complexity of discrete compensation networks typically needed for similar bandwidth devices.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the LT1812 family of low-power, high-speed operational amplifiers. The dual version of this device is the LT1813. For applications requiring higher gain bandwidth products or different supply voltage ranges, other members of the Linear Technology portfolio such as the LT1351 through LT1365 series may be considered. The LT1812 utilizes an advanced low-voltage complementary bipolar process.

Instrumentation, Op Amps, Buffer Amps FAQ

Is the LT1812 stable with capacitive loads?

Yes, the LT1812 is designed to remain stable with capacitive loads up to 1000 pF in unity gain configurations.

How does the shutdown pin function?

Pulling the SHDN pin below V– + 0.4V activates shutdown mode, reducing supply current to approximately 50 µA. Biasing it above V– + 2.0V returns the device to normal operation.
