LTC2067IDD#PBF

Instrumentation, Op Amps, Buffer Amps Overview

The LTC2067IDD#PBF is a dual zero-drift operational amplifier from Analog Devices, housed in a 10-lead (3mm × 3mm) plastic DFN package. It operates within a supply voltage range of 1.7V to 5.25V and supports an industrial temperature range of –40°C to 85°C. The device features a maximum input offset voltage of 10µV and a typical supply current of 7.5µA per amplifier. It includes a shutdown mode with a maximum current draw of 170nA per amplifier.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'IDD' confirms the 10-lead DFN package and I-grade temperature rating. Confirm RoHS compliance via the '#PBF' designation. Ensure the application environment remains within the specified –40°C to 85°C operating range for guaranteed performance.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component for dual-channel precision requirements where low power consumption is critical. The DFN package suits space-constrained designs. Consider the H-grade variant if operation up to 125°C is required. Verify that the 100kHz bandwidth meets the signal processing needs.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the LTC2066/LTC2067/LTC2068 family of micropower zero-drift amplifiers. While sharing core electrical characteristics, the LTC2067 specifically offers dual channels, distinguishing it from the single-channel LTC2066 and quad-channel LTC2068.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

LTC2067HDD#PBF serves as a direct replacement for extended temperature ranges up to 125°C.

Instrumentation, Op Amps, Buffer Amps FAQ

How does the shutdown function operate?

Tying the SHDN pin to V– disables the amplifier, reducing supply current to less than 170nA per amplifier.

What is the input bias current specification?

The input bias current is typically ±5pA at room temperature and does not exceed 150pA over the full specified temperature range.
