LT1206CR#TRPBF

Instrumentation, Op Amps, Buffer Amps Overview

The LT1206CR#TRPBF is a current feedback amplifier manufactured by Analog Devices Inc. in a 7-lead plastic DD package. It operates over an extended temperature range of –40°C to 85°C. Key electrical specifications include a minimum output drive current of 250mA, a small-signal bandwidth of 60MHz at AV=2 with RL=100Ω, and a slew rate of 900V/µs at AV=2 with RL=50Ω. The device features a wide supply voltage range from ±5V to ±15V, high input impedance of 10MΩ, and a shutdown mode reducing supply current to less than 200µA.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific ordering suffix #TRPBF confirms tape and reel packaging. Confirm the CR suffix corresponds to the 7-lead Plastic DD package and the –40°C to 85°C operating temperature range. Ensure compatibility with Linear Technology's proprietary complementary bipolar process requirements.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component for applications requiring high output current drive and excellent video characteristics. Consider the adjustable supply current feature if power consumption needs optimization for lower bandwidth uses. Verify that the 10MΩ input impedance meets circuit requirements.

Instrumentation, Op Amps, Buffer Amps Part Context

The LT1206 series includes variants in 8-lead DIP, 8-lead SO, 7-lead DD, and 7-lead TO-220 packages. The LT1206CR#TRPBF specifically denotes the surface-mount 7-lead DD package version.

Instrumentation, Op Amps, Buffer Amps FAQ

How is the quiescent supply current adjusted?

The quiescent current can be reduced by connecting a resistor from the shutdown pin to ground. The total bias current is approximately 40 times the current flowing out of the shutdown pin.

What is the effect of the COMP pin on performance?

Connecting a capacitor between the output and COMP pins provides compensation for capacitive loads, eliminating peaking. Leaving the COMP pin open disconnects this network, which may result in higher bandwidth but potential peaking with capacitive loads.
