Precision 2.048V reference for ADC/DAC signal chains
The MAX6126BASA21: Initial accuracy is ±0.06%, which means the output is within 1.2 mV of 2.048V at 25°C without trimming — good enough to skip a system calibration step in many industrial and instrumentation designs.
Input voltage range is 2.7V to 12.6V, so the reference can be powered from a regulated 3.3V rail or an unregulated 5V/12V supply — the series topology keeps quiescent current at 725µA regardless of input voltage. Output current is rated 10 mA, enough to drive the reference input of multiple ADCs or a small analog front-end without an external buffer.
Active lifecycle — RoHS non-compliant, sourced to order
RoHS compliance is listed as non-compliant, so this part is exempt from EU RoHS restrictions or intended for legacy BOMs that require tin-lead solder — confirm your assembly's solder alloy and regulatory jurisdiction before committing the line.
