Description
The HL3280 is a miniaturized receiver IC for use in the infrared remote control system.
It has a wide voltage operating such as 2.7~5.5V, a high sensitivity, and good noise immunity.
Wide operating is very suitable to the hand-held battery operating systems, such as electrical toy.
Features
- Wide operating supply voltage 2.7V ~ 5.5 V.
- Built-in internal voltage reference circuit for wide operating.
- Maximum interference safety against optical and electrical disturbances.
- No external components necessary.
- The center frequency can be varied with option PADs ( 32.7kHz, 36.7kHz, 37.9kHz, 40kHz, 56.7kHz).
- Internal filter for a high frequency lighting fluorescent lamp.
- Open collector output (Open collector output with a pull-up.
