Power efficiency
Thanks to its hybrid architecture, the TEC200 provides high power efficiency over a wide range of input voltages and loads, while preserving the low noise and precision expected from a linear driver:
Output voltage noise
Voltage noise between the TEC+ and TEC- pins measured when driving 4 V / 4 A with a TEC200-4V:
Temperature sensing stability
Temperature sensing variation when measuring a high stability 10 kΩ resistor over the -40 °C to 85 °C operating range:
