It delivers a tight ±0.05% initial tolerance and a temperature coefficient of 6ppm/°C, keeping the output stable across the full -40°C to 125°C operating range. Supply current sits at 95µA, and the part can source up to 10 mA to the load. The 8-VSSOP package fits compact layouts where board space is tight. ## Why the ratings matter for the BOM line The ±0.05% tolerance and 6ppm/°C drift mean this reference holds its 5V output within a few millivolts over temperature — critical when feeding a precision ADC or DAC in an automotive ECU where the reference voltage directly sets the conversion accuracy. The 10 mA output current is enough to drive the reference input of most SAR ADCs and a small resistive divider; if your load exceeds that, you'll need a buffer. The 95µA supply current is low enough to keep the always-on rail in a battery-backed module from draining the system. ## Lifecycle and sourcing posture The REF3450QDGKRQ1 carries an active lifecycle status — no end-of-life notice, no last-time-buy clock. That means it can be specified into new designs and multi-year production runs without worrying about a sudden obsolescence-driven redesign.","metaTitle":"REF3450QDGKRQ1 Automotive Series Voltage Reference, ±0.05%","metaDescription":"TI REF3450QDGKRQ1 AEC-Q100 qualified series voltage reference.
