Its ±0.04% initial tolerance and 1.5ppm/°C temperature coefficient place it in the class of references used for 16-bit and higher ADC/DAC systems, precision weigh scales, and calibration-grade instrumentation. The buried zener design delivers lower noise and better long-term stability than bandgap references — the 1.5µVp-p noise in the 0.1Hz to 10Hz band and 1.3µVrms from 10Hz to 10kHz are figures that matter when the reference noise floor must stay well below the converter's LSB. ## Input range and output drive — industrial supply compatibility The 8V to 36V input range lets this reference run directly from a 12V or 24V industrial rail without a preregulator. Output is fixed at 2.5V and can source up to 15 mA — enough to drive several ADC reference inputs or a small divider string. Supply current is 3 mA typical, so the power budget is modest even in multi-channel systems. ## Package and temperature grade Housed in an 8-pin SOIC package (8-SOIC, 0.154\" body width, 3.90mm), surface-mount assembly is straightforward. The -40°C to +85°C operating range covers industrial and outdoor telecom environments. ROHS3 compliant per the current revision.","metaTitle":"MAX6325ESA+ Voltage Reference, 2.5V ±0.04% 1.5ppm/°C","metaDescription":"MAX6325ESA+ series buried zener voltage reference, 2.5V fixed output, ±0.04% tolerance, 1.5ppm/°C drift, 1.5µVp-p noise.

The ±0.04% initial tolerance and 1.5ppm/°C temperature coefficient make it appropriate for 16-bit ADC references, precision DACs, and instrumentation where the reference error must be a small fraction of the system budget.
