Supply current is 725 µA typical — the quiescent draw is low enough that the reference can stay powered continuously in a battery-operated instrument. For a 12-bit system the drift is under 1 LSB. Housed in an 8-MSOP (also called 8-uMAX/uSOP) with 0.118-inch body width and 0.65 mm pin pitch. The land pattern matches the standard MSOP-8 footprint; no exposed thermal pad exists on this package variant, so the primary heat path is through the leads. The 10 mA output current at 12.6 V input dissipates about 105 mW — well within the package's thermal capability without a pad. ## Lifecycle and compliance Lead-bearing termination may affect solder joint reliability in lead-free reflow profiles; verify the reflow peak temperature against the part's MSL rating before committing the BOM.","metaTitle":"MAX6126A21 2.048V Series Voltage Reference, ±0.06%, 5ppm/°C","metaDescription":"MAX6126A21 precision voltage reference: 2.048V fixed output, ±0.06% initial accuracy, 5ppm/°C drift, 1.3µVp-p noise.
