Frequently Asked Questions
What is the required operating voltage range for this receiver module?
The absolute maximum rating specifies that the supply voltage (Pin 2) must fall between -0.3 V and +6.0 V.
Can I use this for high-frequency environments like daylit areas?
Yes, although ambient light interference is possible, the product details graphs help analyze sensitivity under various irradiance levels.
What frequencies are available in the TSOP12 series?
Available models cover several discrete frequency bands, including 30 kHz, 33 kHz, 36 kHz, and up to 56 kHz.
Am I responsible for validating its use in my specific project?
Yes, all operating parameters must be validated for each customer application by the customer.
