Texas Instruments TL4050/TL4050-Q1 Shunt Voltage References

Texas Instruments TL4050/TL4050-Q1 Precision Micropower Shunt Voltage References offer versatility and ease of use, ideal for a wide array of applications. The two-terminal fixed-output devices do not require external capacitors for operation and are stable with all capacitive loads. Furthermore, the reference provides a low dynamic impedance, low noise, and low-temperature coefficient to guarantee a stable output voltage over a wide range of operating currents and temperatures.

The TI TL4050/TL4050-Q1 is available in three initial tolerances, ranging from 0.1% (max) for the A grade to 0.5% (max) for the C grade. Therefore, designers have a great deal of flexibility in choosing the best cost-to-performance ratio for applications. Packaged in the space-saving SOT-23-3 and SC-70 packages and requiring a minimum current of 45µA (typ), the TL4050/TL4050x-Q1 is also excellent for portable applications.

The TL4050xI is characterized for operation over an ambient temperature range of -40°C to +85°C, while the TL4050xQ/TL4050x-Q1 is characterized at -40°C to 125°C.

The TI TL4050-Q1 is AEC-Q100 qualified for automotive applications.
