Frequently Asked Questions

What package does TL851CDG4 use and how many pins does it have for interfacing?

TL851CDG4 is packaged in a 16-pin SOIC (Small Outline Integrated Circuit) with a 0.25-inch pin pitch. The 16-pin count provides adequate signal and power connections for sonar ranging control, and the SOIC outline supports standard pick-and-place SMT assembly with a 260°C peak reflow temperature.

In which sensing applications is TL851CDG4 most commonly used for distance measurement?

TL851CDG4 is primarily used in ultrasonic sonar ranging systems for proximity detection and non-contact distance measurement. Typical applications include industrial obstacle detection at ranges up to several meters, liquid level sensing in tanks, and robotics navigation, all requiring accurate echo-time measurement with minimal discrete component count.

What peak reflow temperature does TL851CDG4 support during PCB soldering and does it comply with lead-free standards?

TL851CDG4 supports a 260°C peak reflow temperature, consistent with standard lead-free SMT soldering profiles. Its JESD-609 Code e4 designation confirms RoHS-compliant, lead-free construction, making it suitable for designs requiring halogen-free and Pb-free assembly processes in consumer and industrial electronics.
