概述
Description
The LTC1051CN8 is an 8-pin DIP dual operational amplifier from Linear Technology (now Analog Devices). It belongs to the LTC1051 family and is designed for precision analog signal conditioning. The device offers very low input bias current and low offset voltage/drift, enabling accurate amplification at low frequencies with minimal error. With micropower consumption compared with standard op-amps, it suits battery-powered and portable instrumentation. The CN8 suffix denotes the DIP-8 plastic package. Common applications include instrumentation front-ends, active filters, integrators, transimpedance stages, and sensor conditioning. For exact electrical characteristics (input offset, gain-bandwidth, slew rate, noise, supply range), consult the datasheet and factory application notes.
