10V shunt reference with tight initial accuracy
The TL4050A10IDBZT is a precision shunt voltage reference from Texas Instruments, delivering a fixed 10V output with ±0.1% initial tolerance. That level of accuracy — one-tenth of a percent — means the reference voltage is guaranteed within 10 mV at room temperature, which is tight enough for a 12-bit ADC's full-scale calibration without an external trim pot. The cathode current range is 103 µA minimum to 15 mA maximum, so the external resistor must be sized to keep the device within that window across load and line variations.
Temperature drift and noise floor
That is stable enough for a precision current source or a data-acquisition system that sees seasonal temperature swings inside an enclosure. In a low-bandwidth measurement path (e.g., a 10 Hz low-pass filter after the reference), the integrated noise drops proportionally; for a 1 kHz signal chain, the 150 µVrms adds about 0.15 LSB of noise to a 12-bit, 10V full-scale ADC.
Package, mounting, and compliance
Supplied in a SOT-23-3 package (also known as TO-236-3 or SC-59), the device occupies minimal board area and suits high-density designs. The three-pin footprint — cathode, anode, and no-connect — is standard for shunt references in this package; the anode ties to ground, the cathode connects through the bias resistor to the positive rail.
