LTKA00CN8#PBF

Sensor And Detector Interfaces Overview

The LTKA00CN8#PBF is a precision operational amplifier component within the LTK001 thermocouple cold junction compensator and matched amplifier kit. Manufactured by Analog Devices Inc., it is designed for high-impedance input applications requiring extremely low offset voltage and bias current. The device operates with a total supply voltage range of 4.5V to 40V and draws a typical supply current of 480µA. It features an input offset voltage of 35µV maximum, input bias current below 600pA, and a large signal voltage gain of 2000 V/mV. The component is housed in an 8-lead PDIP (N8) package and supports an operating temperature range from 0°C to 70°C.

Sensor And Detector Interfaces Feature Summary

• Extremely low input bias current allows the use of high impedance input filters without degrading offset voltage or drift performance.
• Low supply current minimizes warmup drift, ensuring stable operation in precision measurement environments.
• Specially selected for thermocouple applications with very low offset voltage to maintain high accuracy.

Sensor And Detector Interfaces Applications

• Thermocouple cold junction compensation systems
• Precision temperature measurement instrumentation
• High impedance sensor signal conditioning

Sensor And Detector Interfaces Procurement Notes

Verify the specific ordering suffix CN8 corresponds to the 8-lead PDIP package and commercial temperature range when sourcing. Confirm that the component matches the required polarity identifier (0) for compatibility with the LT1025 compensator if used as part of a complete kit. Ensure the supplier provides documentation confirming the device meets the specified electrical characteristics for the LTKA0x series.

Sensor And Detector Interfaces Selection Notes

Select the LTKA00 variant specifically when pairing with an LT1025 compensator identified with a '0' suffix to ensure proper error matching. Consider the LTKA01 variant if the associated compensator carries a '1' identifier. Evaluate the need for hermetic packaging options like the J8 CERDIP or H TO-5 metal can if extended temperature ranges or harsh environmental conditions are required beyond the standard N8 package specifications.

Sensor And Detector Interfaces Part Context

This component serves as the amplifier portion of the LTK001 family, which separates the amplification and cold junction compensation functions to eliminate compensator temperature rise issues. It is distinct from the standalone LT1025 compensator but is electrically matched to it during manufacturing. The LTKA0x designation indicates the amplifier-only version available for multi-channel applications sharing a single compensator.
