概述

Description

LT1461CIS8-5#PBF is a Linear Technology (now Analog Devices) part number for the LT1461 family in an 8‑pin Pb‑free package. The suffix details packaging and options:
- CIS8: 8‑pin package (MSOP‑8/SOIC‑8) with a likely industrial temp grade.
- -5: a specific device variant/version within the LT1461 family.
- #PBF: Pb‑free/RoHS compliant.
The LT1461 family consists of high‑precision, low‑noise analog amplifiers used for instrumentation, ADC driving, and precision signal conditioning. This part is typically used as a precision buffer, gain/feedback element, or transimpedance stage in instrumentation front ends.
For exact electrical specs, pin configuration, recommended operating conditions, and variant details, consult the official datasheet and product data sheet from Analog Devices.

Features

Here are the typical features you’d expect for the LT1461CIS8-5#PBF (industrial temp, Pb-free, 8-pin package) in brief:
- 8-pin Pb-free plastic package (CIS8), industrial temperature range (IS)
- Precision, low-noise operational amplifier
- Very low input offset voltage with low drift
- Low input bias current
- High gain-bandwidth product with fast slew rate for accurate, fast signals
- Wide supply range with good power-supply rejection
- Stable in standard closed-loop configurations and capable of driving typical loads
- Suitable for instrumentation, sensor conditioning (e.g., photodiodes), active filters, and high-precision preamps
Note: exact electrical specs (numbers) vary by revision. For precise parameters (offset, bias current, GBW, slew rate, PSRR, output swing, recommended supply range), please consult the LT1461 datasheet for the CIS8-5#PBF variant.

Package

An 8-pin SO-8 (small-outline) package; Pb-free RoHS-compliant variant.

Pinout

- Pin count: 8 pins (8-pin IS8 package).
- Function: Single-channel precision operational amplifier (monolithic op-amp); LT1461 is the precision op-amp, with -5 indicating the 5V variant; -PBF denotes Pb-free.

Manufacturer

Manufacturer: Analog Devices, Inc. (ADI). The LT1461 originated from Linear Technology, which was acquired by Analog Devices in 2017.
Company type: American multinational semiconductor company that designs, manufactures, and markets analog, mixed-signal, and DSP integrated circuits.

Application

LT1461 is a high-speed, precision op-amp. Common application areas include:
- Sensor front-ends and instrumentation amplifiers
- Transimpedance amplifiers for photodiodes
- High-speed data acquisition front-ends
- Active filters and equalizers
- ADC/DAC drive and reference buffering
- Power-supply error amplifiers in regulators
- Control/servo loops requiring low drift and fast settling
(Packaging, PBF version mainly affects mounting; function remains the same.)
