HL3280 - PREAMPLIFIER

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.
