TL851 Description

Short technical summary and product information.

The TL851 from TERA-LOGIC is an economical digital I2L ranging control integrated circuit. It is designed for use in sonar ranging modules and facilitates distance measurement from six inches to 35 feet.

 

The device operates with a single supply voltage ranging from 4.5 V to 6.8 V and is characterized for operation between 0°C and 40°C. It features an internal oscillator that utilizes a low-cost external ceramic resonator, typically 420 kHz, to drive a 50 kHz electrostatic transducer.

 

Key features include an accurate clock output for external use, a synchronous 4-bit gain control output for interfacing with receivers like the TL852, and an internal 1.2-V level detector for receive functions. The device also incorporates internal blanking to exclude false receive inputs and echoes from objects closer than 1.3 feet, with an option to shorten this blanking period.

 

The TL851 is housed in a SON package and is suitable for surface mount applications. Its TTL-compatible interface simplifies integration into various sonar ranging systems.
