The MAX6350ESA is a buried-zener series voltage reference providing a fixed 5V output. It operates within an input voltage range of 8V to 36V and supports ±15mA source/sink currents. The device features a maximum temperature coefficient of 1.5ppm/°C, initial accuracy of ±0.02%, and low noise (3µVp-p at 0.1Hz-10Hz). It consumes approximately 3.3mA supply current and functions across -40°C to +85°C in an 8-pin SO package.
Verify the specific suffix 'E' confirms the extended temperature range (-40°C to +85°C) and 'SA' indicates the 8-pin SO package. Confirm RoHS compliance status as '+'. Ensure the datasheet revision matches the required specifications for line regulation and long-term stability before finalizing procurement.
Select this component when high precision and low noise are critical for 16-bit data conversion systems. The buried-zener architecture ensures superior stability compared to bandgap references. Consider the trim pin if tighter tolerance than ±0.02% is required, or use the NR pin for additional wideband noise suppression.
Part of the MAX6325/MAX6341/MAX6350 family offering 2.5V, 4.096V, and 5V outputs respectively. Shares identical pinouts and functional characteristics, differing primarily in factory-set output voltage. Designed for laboratory-standard temperature stability without requiring heated reference power consumption.
MAX6350CSA provides the same electrical characteristics but is rated for commercial temperature range (0°C to +70°C). Verify thermal requirements match the application environment before substituting.
