HS0038BD Integrated Infrared Receiver Module SIP-3

HS0038BD Integrated Infrared Receiver Module SIP-3 provides a compact and sensitive solution for infrared (IR) remote control and data reception, integrating a photodetector and preamplifier in one small package. This module is specifically tuned to receive data modulated at 38 kHz, the standard carrier frequency for most consumer electronics and remote control protocols like NEC and RC5. Consequently, the HS0038BD simplifies your design significantly by eliminating the need for external filtering and amplification circuits, offering a TTL-compatible digital output directly proportional to the received IR signal. Furthermore, its robust shielding against electrical field disturbances ensures stable performance even in noisy environments. Therefore, designers frequently choose this reliable component for implementing cost-effective and space-saving remote control functionality in various embedded systems.

Key Features:

• Integrated Preamplifier and Filter: The built-in circuitry handles automatic gain control (AGC), bandpass filtering, and demodulation, simplifying external interface requirements.
• Optimized for 38 kHz: This device is precisely tuned for a 38.0 kHz carrier frequency, ensuring high sensitivity and reliable decoding for standard IR protocols.
• Low Power Consumption: Operating with a low supply current makes it an ideal component for battery-operated and energy-efficient systems.
• TTL and CMOS Compatibility: The active low, open-collector output provides direct interfacing with microcontrollers and digital logic circuits.
• Shielding Against Noise: The internal encapsulation and design effectively reject external noise and electromagnetic interference (EMI).

Pinout and Wiring:

• Pin 1 (OUT): Connect this pin to the microcontroller’s digital input pin. This output is active-low (sinks current when a signal is received).
• Pin 2 (GND): Connect the ground pin to the circuit ground (0 V).
• Pin 3 (V_S): Connect this pin to the supply voltage (typically +5V or +3.3V).
• Wiring Note: Always place a small decoupling capacitor (e.g., 4.7 μF in parallel with a 0.1 μF ceramic capacitor) between V_S and GND as close as possible to the module to suppress power supply noise.
