Technical Specifications
The HCNR201-000 consists of an input LED, a feedback photodiode (PD1), and an output photodiode (PD2). The LED emits light proportional to the input current, which is then detected by PD1. A feedback circuit adjusts the LED current to maintain a linear relationship between the input and output signals. The output signal is derived from PD2.
Key specifications include:
- Linearity: 0.01% (typical)
- Bandwidth: DC to 200 kHz
- Isolation Voltage: 5000 Vrms
- Input Current: 0 to 20 mA
- Output Voltage: 0 to 5 V
- Operating Temperature: -40°C to +85°C
The HCNR201-000 is a high-performance analog optocoupler that provides excellent linearity and isolation for a wide range of applications. Its accurate signal transmission and robust design make it an ideal choice for demanding analog isolation requirements.
