Visão Geral

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.

Equivalent

Direct pin-for-pin equivalents for LTC1051CN8 do not exist; LTC1051 is a chopper-stabilized, precision op-amp. Closest functional equivalents from other vendors:
- Analog Devices: ADA4528-1 (single) / ADA4528-2 (dual) – zero-drift precision op-amps
- TI: OPA333 (single) / OPA2333 (dual) – zero-drift, low-power
- TI: OPA2277 (dual) – precision, low-drift
Note: verify pinout and supply ranges; exact pin-compatible packages may require adapters.

Features

LTC1051CN8 features (8-pin DIP):
- Precision, chopper-stabilized op-amp with ultra-low input offset voltage and drift
- Very low input bias current for high-impedance sources
- Low noise and stable performance over temperature
- Low quiescent current for long battery life
- Wide supply range; supports single-supply and dual-supply operation
- Input common-mode range includes the negative rail; output can swing close to rails under light load
- 8-pin DIP package (CN8) for easy PCB integration
Ideal for high-precision amplification of low-level/high-impedance signals, instrumentation, and sensor conditioning.

Pinout

- Pin count: 8 pins (8-pin package, e.g., DIP8/SO8)
- Function: Operational amplifier (op-amp) device (single-supply, micropower type).

Manufacturer

Manufacturer: Linear Technology Corporation (LTC). It is an American semiconductor company specializing in analog integrated circuits and power-management devices; Linear Technology was acquired by Analog Devices and is now part of Analog Devices.
