LTKA01CN8#PBF

Sensor And Detector Interfaces Overview

The LTKA01CN8#PBF is a precision operational amplifier component within the LTK001 thermocouple conditioning kit, manufactured by Analog Devices Inc. It is designed for high-impedance input applications requiring low supply current and minimal warmup drift. The device features an extremely low input offset voltage of less than 35µV and input bias currents below 600pA. It operates on a total supply voltage range of 4.5V to 40V with a typical supply current of 480µA. The amplifier provides a large signal voltage gain of up to 2000 V/mV and includes offset trim capabilities. It is housed in an 8-pin PDIP (N8) package and is specifically matched with LT1025 cold junction compensators having a '1' identifier.

Sensor And Detector Interfaces Feature Summary

• Specially selected for thermocouple applications with low supply current to minimize warmup drift
• Extremely low input offset voltage and bias currents allowing use of high impedance input filters
• Direct matching with specific polarity LT1025 cold junction compensators to eliminate worst-case error summation

Sensor And Detector Interfaces Applications

• Thermocouple cold junction compensation systems
• High accuracy temperature measurement instrumentation
• Industrial process control loops requiring Type E, J, K, R, S, or T thermocouples

Sensor And Detector Interfaces Procurement Notes

Verify the part number suffix CN8 corresponds to the 8-lead PDIP package. Confirm the '01' designation matches the required LT1025 compensator polarity. Check datasheet for obsolete package status and lead material specifications if RoHS compliance is critical.

Sensor And Detector Interfaces Selection Notes

Select this amplifier when paired with an LT1025 compensator marked with a '1'. Ensure supply voltages remain within the 4.5V to 40V range. Consider the LTC1050 if lower offset voltage is needed for Type R and S thermocouples due to inherent 35µV offset limitations.

Sensor And Detector Interfaces Part Context

This component serves as the amplification stage in the LTK001 family of thermocouple conditioners. It complements the LT1025 cold junction compensator. The kit approach separates functions to prevent compensator self-heating from affecting the amplifier. It belongs to the LT series of precision analog components.
