The **TSOP132..P10TR** series represents a specific line of miniaturized infrared (IR) receiver modules designed for remote control systems. These components integrate a PIN diode and a preamplifier into a single lead frame, encapsulated in an epoxy package that acts as an IR filter. --- ### 1. General Specifications The "P10TR" suffix typically refers to the packaging style (Top View) and the tape-and-reel shipping format. | Parameter | Specification | | :--- | :--- | | **Supply Voltage ($V_S$)** | 2.5 V to 5.5 V | | **Supply Current ($I_S$)** | 0.7 mA (typical) | | **Transmission Distance** | Up to 45 meters | | **Carrier Frequency** | 30 kHz to 56 kHz (model dependent) | | **Output Type** | Active Low (Logic 0 when IR is detected) | --- ### 2. Internal Functional Blocks The device is much more than a simple photodiode; it contains complex circuitry to ensure reliable communication: 1. **PIN Photodiode:** Converts the IR light signal into an electrical current. 2. **Preamplifier:** Boosts the weak signal from the photodiode. 3. **Automatic Gain Control (AGC):** Adjusts sensitivity to compensate for ambient light noise. 4. **Band Pass Filter:** Specifically tuned to the carrier frequency (e.g., 38kHz) to block interference from fluorescent lights or sunlight. 5. **Demodulator:** Removes the carrier frequency and outputs the raw data bits. --- ### 3. Pin Configuration (P10 Package) The P10TR variant is a surface-mount (SMD) device. While always verify with the specific datasheet, the standard pinout for this series is: * **Pin 1 (OUT):** Data output signal. * **Pin 2 (GND):** Ground connection. * **Pin 3 ($V_S$):** Power supply input. --- ### 4. Key Application Circuitry To ensure stable operation, a simple RC filter is recommended on the supply line to suppress power ripples. ```cpp // Typical Hardware Setup // [VS] ----[ 100 Ohm Resistor ]----+----[ Pin 3 (VS) ] // | // [ 4.7 uF Capacitor ] // | // [GND] ---------------------------+----[ Pin 2 (GND) ] // [MCU Pin] <--------------------------[ Pin 1 (OUT) ] ``` --- ### 5. Selection Criteria When using the TSOP132 series, the **AGC version** is critical. * **TSOP132/134:** Optimized for short burst codes (like RC5/RC6). * **TSOP131/133:** Optimized for continuous data or long bursts. * **P10TR:** Indicates a surface mount package oriented for "Top View" reception, provided on a tape for automated assembly.
