Overview

Description

LT1990CS8 is a Linear Technology (now Analog Devices) IC. The “CS8” suffix indicates an 8‑pin package variant. The LT1990 family consists of precision, high‑speed operational amplifiers used for instrumentation, data acquisition, and signal conditioning front ends. Typical uses include buffering sensors, forming transimpedance/amplifier stages, and video/analog front ends, depending on the exact revision.
Key idea: the CS8 part is the orderable 8‑pin version of LT1990; exact specs (supply range, input offset/bias, gain bandwidth, slew rate, pinout) vary by variant. To get a concise intro with concrete numbers, see the LT1990 datasheet on Analog Devices’ website or your supplier’s product page. If you have a specific application or revision, I can summarize the exact features and recommended layouts.

Package

LT1990CS8 comes in an 8‑lead plastic surface‑mount package, i.e., an SOIC‑8 (Small Outline Integrated Circuit) package.

Pinout

- Pin count: 8 pins (8-pin package, i.e., SO-8/MSOP-8).
- Function: High-speed, precision differential amplifier (instrumentation/difference amplifier) used for converting small differential signals to a single-ended output with gain set by external feedback resistors.

Manufacturer

Manufacturer: Analog Devices, Inc. (ADI). It’s a multinational semiconductor company that designs and manufactures analog, mixed-signal, and digital signal processing integrated circuits (it acquired Linear Technology, the original source of the LT parts, in 2017).

Application

LT1990CS8 is used for precision, low-drift signal conditioning and current sensing. Common application areas include:
- Low-noise transimpedance/preamplification for photodiodes
- Precision current-sense and window comparator circuits in power supplies and motor drivers
- Instrumentation-amp front-ends for bridges, RTDs, and strain gauges
- Battery-powered sensor interfaces and data-acquisition front ends
- Medical/industrial instrumentation and audio preamps
