LT1007CN8#PBF

Instrumentation, Op Amps, Buffer Amps Overview

The LT1007CN8#PBF is a single-channel, low noise, high speed precision operational amplifier manufactured by Analog Devices Inc. It features guaranteed maximum input offset voltage of 25mV and maximum drift of 0.6mV/°C at 25°C. The device provides a typical gain bandwidth product of 8MHz and a slew rate of 2.5V/ms. Input noise density is specified as 4.5nV/√Hz at 10Hz and 3.8nV/√Hz at 1kHz, with typical 0.1Hz to 10Hz peak-to-peak noise of 60nV. Common mode rejection ratio is guaranteed at a minimum of 117dB. It operates within a supply voltage range of ±10V to ±15V and functions in an industrial temperature range of 0°C to 70°C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific package designation N8 corresponds to the 8-lead PDIP configuration required for your PCB footprint. Confirm that the C suffix indicates the commercial grade operating temperature range of 0°C to 70°C. Ensure the #PBF suffix denotes lead-free compliance and RoHS adherence before finalizing component selection for production assemblies.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when system requirements demand exceptionally low voltage noise combined with high DC precision. The LT1007 is suitable for applications where low 1/f noise is critical, such as sensor interfaces. Consider the 8MHz bandwidth and 2.5V/ms slew rate against higher-speed alternatives if transient response is less critical than noise floor performance.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the LT1007/LT1037 series of monolithic operational amplifiers designed for precision analog applications. The LT1007 variant is unity-gain stable, distinguishing it from the decompensated LT1037 which requires a minimum closed-loop gain of five. Both share similar low-noise architectures but differ in stability compensation and bandwidth specifications.

Instrumentation, Op Amps, Buffer Amps FAQ

How does the LT1007 handle differential input voltages?

The inputs are protected by back-to-back diodes. If the differential input voltage exceeds -0.7V, the input current should be limited to 25mA to prevent damage.

What is the recommended method for adjusting input offset voltage?

A 10kΩ nulling potentiometer can be used between the VOS TRIM pins. Trimming to a non-zero value creates additional drift calculated as (VOS / 300)mV/°C.
