LT1014CN#PBF

Instrumentation, Op Amps, Buffer Amps Overview

The LT1014CN#PBF is a quad precision operational amplifier manufactured by Analog Devices Inc. It features four independent amplifiers in a 14-lead PDIP package. Key electrical specifications include an input offset voltage of 60µV, input bias current of 12nA, and gain-bandwidth product of 800kHz. The device operates on supply voltages ranging from 4V to 44V with a typical supply current of 350µA per amplifier. It provides a slew rate of 400mV/µs, common mode rejection ratio of 117dB, and power supply rejection ratio of 117dB.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Directly upgrades designs in the industry standard 14-pin DIP LM324/LM348 pin configuration without compromising specifications.
• Single supply operation with input common mode range extending to ground and output swinging to within millivolts of ground.
• Includes phase reversal protection circuitry to prevent output lock-up when inputs fall below the negative rail.
• All-NPN output stage maintains low output resistance and high gain characteristics until saturation.

Instrumentation, Op Amps, Buffer Amps Applications

• Battery-powered precision instrumentation
• Strain gauge signal conditioners
• Thermocouple amplifiers
• 4mA to 20mA current loop transmitters

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix CN#PBF corresponds to the commercial temperature grade (0°C to +70°C) and 14-lead PDIP package. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor declarations prior to integration. Ensure the ordering information matches the required lead-free finish and packaging format for the intended manufacturing process.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a quad op amp is required that replaces legacy LM324 designs but demands higher precision. It is suitable for applications requiring low offset voltage and drift without the need for external nulling terminals. Consider the single-supply capability and ground-referenced input/output ranges for battery-operated systems where power efficiency and signal integrity are critical constraints.

Instrumentation, Op Amps, Buffer Amps Part Context

The LT1014 is part of the LT1013/LT1014 family of precision operational amplifiers. It serves as the quad-channel counterpart to the dual-channel LT1013. Both devices were designed to upgrade popular general-purpose amplifiers like the MC1458 and LM158 while offering superior performance metrics such as lower noise and higher gain. The CN variant specifically denotes the commercial temperature range option within the broader LT1014 product line.

Instrumentation, Op Amps, Buffer Amps FAQ

Does the LT1014 require external offset null terminals?

No, the quad configuration does not provide offset null terminals; the low offset voltage is achieved internally.

What happens if the input voltage falls below ground during single-supply operation?

The device includes phase reversal protection circuitry that prevents the output from reversing phase, unlike previous single-supply designs.
