Precision 2.048V reference for ADC and sensor bias
The MAX6037BAUK21-T is a low-power, fixed-output series voltage reference from Analog Devices, delivering 2.048 V with ±0.3% initial accuracy and a 50 ppm/°C temperature coefficient. The 5 mA output current is enough to bias the reference input of multiple ADCs or a precision sensor bridge without an external buffer.
Noise and drift — what the numbers mean for your signal chain
The 50 ppm/°C temperature coefficient means the output shifts roughly 100 µV over a 100°C swing — for a 12-bit system with a 2.048 V reference, that is about 0.2 LSB of drift, acceptable for most industrial control but a factor to budget in a 16-bit design.
Package, mounting, and procurement reality
Housed in a SOT-23-5 (SC-74A) surface-mount package, the part is marked with supplier device package SOT-23-5 and ships in Bulk — not tape-and-reel, so confirm the handling and placement method for your pick-and-place line. Note the RoHS compliance status: this part is marked RoHS non-compliant. If your bill of materials requires RoHS exemption or you serve markets where RoHS is not mandated, this reference is still available; otherwise look at the RoHS-compliant suffix variants in the MAX6037 family.
