Precision 5V reference for automotive and industrial analog chains
The Maxim Integrated MAX6175BASA/V+T is a series voltage reference that delivers a fixed 5V output with ±0.1% initial accuracy. Rated for the full -40°C to 125°C automotive temperature range and AEC-Q100 qualified, it is designed for precision bias and ADC/DAC reference in engine control units, transmission controllers, battery-management systems, and other under-hood or high-temperature industrial environments. The 10ppm/°C temperature coefficient keeps the output stable across the operating range—critical for maintaining system accuracy when the ambient temperature swings.
What the key ratings mean for the BOM
The 5V fixed output eliminates the need for external resistor dividers and the ±0.1% tolerance sets the floor for system accuracy.
Lifecycle and sourcing reality
It is ROHS3 compliant. For BOM-freeze planning, this is a stable line item—no imminent obsolescence risk. The date-code and lot traceability should be verified on receipt, particularly if the part has been in inventory for extended periods—the laser etch on the 8-SOIC body is a forensic checkpoint for authenticity.
