ADC8494 - (ADC8494 - ADC8497) Precision Thermocouple Amplifiers

Download the ADC8494 datasheet PDF. This datasheet also covers the ADC8495 variant, as both devices belong to the same (adc8494 - adc8497) precision thermocouple amplifiers family and are provided as variant models within a single manufacturer datasheet.

General Description

The AD8494/AD8495/AD8496/AD8497 are precision instrumentation amplifiers with thermocouple cold junction compensators on an integrated circuit.

They produce a high level (5 mV/°C) output directly from a thermocouple signal by combining an ice point reference with a precalibrated amplifier.

Key Features

  • Low cost and easy to use Pretrimmed for J or K type thermocouples Internal cold junction compensation High impedance differential input Standalone 5 mV/°C thermometer Reference pin allows offset adjustment Thermocouple break detection Laser wafer trimmed to 1°C initial accuracy and 0.025°C/°C ambient temperature rejection Low power:.
