TDC-GP22

The TDC-GP22 is a high-precision Time-to-Digital Converter (TDC) from *ACAM-Messelectronic GmbH*. It measures time intervals between electrical signals with picosecond-level resolution, making it ideal for applications like ultrasonic flow metering, laser rangefinding, and medical imaging.
Key features include:
- Dual-channel measurement with 22 ps resolution.
- Low power consumption (suitable for battery-powered devices).
- SPI interface for easy microcontroller integration.
- On-chip temperature sensor for compensation.
The TDC-GP22 excels in time-of-flight (ToF) measurements, enabling accurate distance or flow calculations. Its compact design and robust performance make it a popular choice for industrial and scientific applications requiring precise timing.
For more details, refer to the datasheet or ACAM’s documentation.

The TDC-GP22 (Time-to-Digital Converter) has equivalents like:
- TDC-GP21 (earlier version, lower resolution).
- TDC7200 (Texas Instruments, similar high-precision TDC).
- TDC-GP30 (higher channel count).
- ACAM TDC-GPX (same family, advanced features).
- TDC1000 (TI, ultrasonic-focused but with TDC functionality).
For exact replacements, check datasheets for compatibility.

The TDC-GP22 is manufactured by ACAM Messelectronic GmbH, a German company specializing in high-precision time-to-digital converters (TDCs) and measurement solutions. Founded in 1999 and headquartered in Stutensee, Germany, ACAM is known for its innovative timing and sensing technologies, catering to industries like industrial automation, medical imaging, and LiDAR. The company was acquired by ams AG (now ams-OSRAM AG) in 2015, enhancing its reach in advanced sensor and semiconductor solutions. ACAM's TDCs, like the TDC-GP22, are widely used for ultra-precise time interval measurements.

The TDC-GP22, a high-precision time-to-digital converter, is widely used in:
1. Lidar & Distance Measurement – For accurate time-of-flight calculations.
2. Flow Metering – Ultrasonic flow measurement in industrial and medical applications.
3. Medical Imaging – Time-resolved detection in PET scanners and ultrasound.
4. Particle Physics – High-energy physics experiments requiring precise timing.
5. Industrial Automation – Position sensing and object detection.
6. Communication Systems – Synchronization and time-stamping in 5G and IoT.
Its low power consumption, high resolution (~10 ps), and compact design make it ideal for portable and embedded systems.

The TDC-GP22 is available in a QFN-32 (Quad Flat No-leads) package, measuring 5x5 mm with a 0.5 mm pitch. This compact, surface-mount package is suitable for high-precision time measurement applications, offering good thermal and electrical performance.
