LT1210CR

Instrumentation, Op Amps, Buffer Amps Overview

The LT1210CR is a current feedback amplifier manufactured by Analog Devices Inc. in a 7-lead DDPAK package. It provides a minimum output drive current of 1.1A and operates with supply voltages ranging from ±5V to ±15V. The device features a bandwidth of 35MHz at AV=2 with a 10Ω load, and a slew rate of 900V/µs under the same conditions. Input offset voltage is specified at ±3mV typical, with a supply current of 35mA typical. The component supports an operating temperature range of 0°C to 70°C.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• High output drive capability with 1.1A minimum current for driving low impedance loads
• Stable operation with large capacitive loads up to 10,000pF using optional compensation
• Shutdown mode reduces supply current to less than 200µA for power conservation
• Adjustable supply current via external resistor to optimize performance for lower bandwidth applications

• Cable Drivers
• Video Amplifiers
• ADSL Drivers
• Test Equipment Amplifiers
• Buffers

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific ordering suffix #PBF indicates lead-free finish compliance when sourcing this component. Confirm that the DDPAK-7 package matches your PCB footprint requirements. Ensure the commercial temperature grade (0°C to 70°C) aligns with your system's environmental specifications rather than the industrial grade variant.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select the LT1210CR for applications requiring high current drive into low impedance loads such as 10Ω cables. Consider the thermal resistance characteristics of the DDPAK package for heat dissipation needs. Use the shutdown pin to manage power consumption if the amplifier is intermittently active. Verify feedback resistor values to maintain stability and desired bandwidth without excessive peaking.

Instrumentation, Op Amps, Buffer Amps Part Context

The LT1210 series includes variants in TO-220 and SO-16 packages. The LT1210CR specifically utilizes the 7-lead plastic DDPAK package suitable for surface mount or chassis mounting. Other grades like LT1210IR offer extended temperature ranges. The family is designed for high-speed signal processing where large-signal performance is critical.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

LT1210CR#PBF serves as the lead-free equivalent to the non-PBF version. Cross-reference with LT1210CT7 for through-hole TO-220 requirements or LT1210CS for SO-16 surface mount options depending on thermal and mechanical constraints.
