Tsop1738 Proteus Library Download ((new)) 🆓
Deep paper: TSOP1738 IR Receiver — characteristics, modeling, and Proteus library use
Step 1: Locate the Proteus Library Folder
- Default paths:
- Proteus 7:
C:\Program Files\Labcenter Electronics\Proteus 7\LIBRARY
- Proteus 8/9:
C:\ProgramData\Labcenter Electronics\Proteus 8 Professional\LIBRARY
- Note:
ProgramData is a hidden folder. Type it manually in File Explorer.
Step 5: Place and Simulate
- Place the TSOP1738 in your schematic.
- Connect VCC to +5V, GND to 0V, and OUT to a digital pin of a microcontroller (e.g., Arduino or PIC) or an oscilloscope.
- Use an IR signal generator in Proteus (e.g., a 38 kHz square wave source + LED) to test.
6. Proteus modeling strategy
Goal: create a Proteus library part that behaves like a TSOP1738 in mixed-signal simulations (digital stimulus from IR emitter modeled as a 38 kHz ASK carrier).
6.1. Model components
- Analog optical channel: optional voltage source representing received carrier amplitude proportional to transmitter drive and distance (user-adjustable).
- Band-pass filter: simulate center frequency (38 kHz) and Q to model sensitivity to off-frequency carriers.
- Envelope detector: rectify & low-pass to produce demodulated baseband.
- Threshold/Schmitt comparator: produces digital output with configurable thresholds, propagation delay, and active-low output behavior.
- Noise source: add adjustable Gaussian and low-frequency ambient bias to simulate sunlight.
6.2. Implementation options in Proteus
- Use SPICE subcircuit (analog behavioral components) to model band-pass and detector.
- Alternatively implement simplified behavioral model using Proteus VSM mixed-mode: an analog voltage input representing received IR amplitude drives a comparator macro to produce logic output.
- Define parameters: center_freq (38k), bandwidth, amplitude_gain, propagation_delay, output_type (open-collector or push-pull), supply_range, noise_level.
6.3. Symbol and footprint
- Symbol: three pins — Vcc, GND, OUT (optionally a VIN/IR_IN analog pin if modeling optical front-end separately).
- Footprint: small 3-pin TO-92 style or SMD package shape per mechanical specs (TSOP series has a flat package with three pins); include correct pin mapping.
Common Errors & Fixes After Installing
| Error | Probable Cause | Fix |
|-------|----------------|-----|
| “Component not found” | Wrong library folder | Check path: use LIBRARY folder (not MODELS) |
| Simulation running but no output | Missing model data | The downloaded library may be symbol-only. Add a simple SPICE directive or use workaround. |
| Proteus crashes on place | Corrupt .IDX file | Delete both files, re-download from trusted source. |
| Output always LOW or HIGH | Wrong pin assignment | Verify that pin 1 = OUT, pin 2 = GND, pin 3 = VS (data sheet pinout) |
1. Use a logic-level IR model
Some Proteus enthusiasts use the SFH5110 or TFMS5360 models (similar pinout and function). Tweak the frequency parameter to 38 kHz.
Important Note:
TSOP1738 is an active component with complex internal AGC/demodulation. For accurate simulation, many engineers don't simulate the receiver itself – instead, they: tsop1738 proteus library download
- Simulate the transmitted 38 kHz signal
- Replace the TSOP1738 with a digital logic input (low when IR signal is present)
Would you like a step-by-step guide on creating a custom TSOP1738 symbol in Proteus or building a behavioral model for simulation?
The TSOP1738 IR receiver is not included in the standard Proteus library by default, so you must download and add it manually to simulate IR-based circuits. 1. Download the Library
You can typically find the TSOP1738 or a compatible "Infrared Sensor Library" on community engineering sites: Default paths:
The Engineering Projects: Offers a widely used Infrared Sensor Library for Proteus which includes TSOP-style receiver models.
GitHub Repositories: Look for collections like Karan-nevage/PROTEUS-LIBRARY for missing sensor components. 2. Installation Steps
Once you have downloaded the .zip or .rar file, follow these steps to install it: type TSOP1738 .

Step 4: Check the Component Picklist
- Click on the Component Mode (P icon).
- In the Keywords box, type
TSOP1738.
- If installed correctly, it will appear in the results.
