Description
LT1461CIS8-5#PBF is the Linear Technology (now Analog Devices) part number for the LT1461 precision operational amplifier in an 8-pin SOIC package. The CIS8 indicates an 8-pin SOIC package; the “Industrial” temp variant; and the “#PBF” suffix means Pb-free, RoHS-compliant packaging. The “5” is a house option code for a specific voltage/package variant in this family.
The LT1461 is intended for precision amplification and instrumentation—useful in sensor conditioning, transimpedance, and signal-processing front ends. It emphasizes low offset voltage, low bias currents, and stable performance over its supply range.
For exact electrical specs (input offset, bias, gain bandwidth, slew rate, supply voltage range, etc.) and to confirm the option code, consult the LT1461 datasheet and the “Ordering Information” table.

Equivalent
LT1461CIS8-5#PBF is Linear Technology’s MSOP-8 precision op-amp. There’s no single universal cross; equivalents depend on the exact specs you require. Common MSOP-8 dual op-amp cross-references with similar performance include Analog Devices ADA4528-2/ADA4528-1 and AD8628/AD8629; Texas Instruments OPA2365/OPA2376. For precise matches, use a distributor cross-reference (Digikey/Mouser) with your target parameters (supply, offset, noise, GBWP, temperature).
Features
LT1461CIS8-5#PBF is an 8-pin (Pb-free) Linear Technology device in a CIS8 package. Typical features you can expect (check the exact datasheet for numbers):
- Precision, low-noise operation for accurate signal amplification
