Product details

Active dual op-amp with 44 V supply headroom

It operates from a single 2.5 V supply up to 44 V, or dual supplies up to ±22 V, making it suitable for both 3.3 V battery gear and 24 V industrial control loops.

1.2 MHz GBW with 205 µA per channel

Each amplifier delivers 1.2 MHz gain-bandwidth product and 0.4V/µs slew rate, adequate for audio-frequency signal conditioning and sensor amplification. Supply current is 205 µA per channel, a trade-off that keeps power dissipation low in the 3x3 mm DFN package.

Active production, ROHS3 compliant

It is ROHS3 compliant.

Frequently asked questions

What is the typical application for LT1638IDD#PBF?

As a general-purpose dual op-amp with rail-to-rail output and a 2.5 V to 44 V supply range, it is used in sensor signal conditioning, battery-powered instrumentation, active filters, and industrial control loops where low power and wide supply flexibility are needed.

How does LT1638IDD#PBF compare to LT1639?

The LT1638IDD#PBF is a dual op-amp; the LT1639 is a quad version. Both share the same 1.2 MHz GBW, 0.4V/µs slew rate, and 205 µA per channel supply current. The LT1638 comes in an 8-pin DFN, while the LT1639 uses a 14-pin package. For a dual-channel design, the LT1638 saves board space and cost.
