For a 16-bit converter with a 2.048V reference, that noise contribution sits below 1 LSB, so the reference does not limit the converter's effective resolution. Rated to source or sink 10mA of output current, the reference can drive the reference input of multiple SAR ADCs or a single delta-sigma converter without an external buffer. The 725µA quiescent supply current is the price of that drive — budget it into the system power envelope. The 12ppm/°C drift specification means the output voltage shifts by roughly 24.6µV per degree — at 125°C the total drift from 25°C is about 2.46mV, or 0.12% of the 2.048V output, which tracks the initial tolerance band. ## 8-MSOP package — footprint and board integration Housed in an 8-lead MSOP/TSSOP package with 0.118-inch (3.00mm) body width, the MAX6126B21+ uses the standard 8-uMAX/uSOP footprint. The surface-mount package suits automated assembly lines and reflow profiles typical for mixed-signal boards. Supplied in tube format — the tube quantity is the standard handling unit for this package. For reel or tape-and-reel requirements, confirm the alternate order code suffix with your sourcing contact. RoHS3 compliant (2015/863/EU) with no exemptions — the part ships lead-free and is suitable for EU-market products without a RoHS waiver.","metaTitle":"MAX6126B21+ Analog Devices Voltage Reference, 2.048V, ±0.1%","metaDescription":"MAX6126B21+ series voltage reference, 2.048V fixed output, ±0.1% tolerance, 12ppm/°C drift.
