概要
Description
The AD8495ARMZ is a precision thermocouple amplifier from Analog Devices, designed to simplify temperature measurement. It integrates a high-gain instrumentation amplifier, a cold-junction compensation (CJC) circuit, and a fixed-gain output stage, providing a linear voltage output proportional to temperature (5 mV/°C).
Key features:
- Thermocouple Compatibility: Works with J- or K-type thermocouples.
- Cold-Junction Compensation: Built-in CJC eliminates the need for external sensors.
- Wide Supply Range: Operates from +2.7V to +36V, suitable for industrial applications.
- High Accuracy: ±2°C typical error over 0°C to 50°C (ambient).
- Small Package: 8-lead MSOP for space-constrained designs.
Applications include industrial temperature monitoring, HVAC systems, and instrumentation. The AD8495ARMZ simplifies signal conditioning, reducing external component count.
