CXA1511L - Preamplifier for Remote Control Signal Reception

General Description

The CXA1511L/M is a bipolar IC used for preamplifiers that receive signals in infrared remote control systems.

These ICs consist of a first-stage amplifier, limiter amplifier, band-pass filter, band elimination filter, signal waveform detection circuit and waveform shaping circuit.

Key Features

  • Low power consumption (VCC = 5V, 9mW typ. ).
  • Low supply voltage (VCC = 5V).
  • Filters (center frequency can be varied through external resistor: fo = 30kHz to 60kHz, 40kHz typ. ).
  • Elimination of inductors prevents magnetic field inductance interference.
  • Optical reception diode can be coupled directly.
  • Collector output (pull-up resistor, TTL and CMOS can be connected directly).
