DESCRIPTION

1 = OUT, 2 = GND, 3 = V_S

The TSOP14838 is a miniaturized receiver for infrared

remote control systems. A PIN diode and a preamplifier are

assembled on a lead frame, the epoxy package acts as an

IR filter.

The demodulated output signal can be directly decoded by

a microprocessor. The TSOP14838 is compatible with all

common IR remote control data formats.

This component has not been qualified according to

automotive specifications.

Input

AGC

The external components R and C are optional

to improve the robustnes against electrical overstress

(typical values are R = 100 Ω, C = 0.1 µF).

Control circuit

GND

The output voltage V_Oshould not be pulled down to a level

below 1 V by the external circuit.

The capacitive load at the output should be less than 2 nF.
