Its 13 mA supply current is the baseline for the entire signal chain — budget this into the system power rail, and note that the transducer drive current adds on top during burst cycles. ## Interface flexibility and temperature grade The part accepts both analog and digital input signals and communicates measurement results over an SPI output, giving the host MCU direct register access to time-of-flight and amplitude data. Rated for -25°C to 105°C ambient, this covers the under-hood automotive temperature band and industrial enclosures where the internal rise stays below 85°C — a parking-sensor ECU or a tank-level transmitter in a factory sees this range without margin issues. ## Lifecycle and compliance status ROHS3 compliant, which covers the full ten-substance restriction plus the four phthalates — no additional exemption paperwork needed for EU or UKCA markets.","metaTitle":"TUSS4440TRTJT Ultrasonic Sensor Interface, 13 mA, SPI","metaDescription":"Texas Instruments TUSS4440TRTJT ultrasonic sensor interface with analog/digital input and SPI output.
