Precision 4.096V rail for ADC and DAC reference inputs
The MAX6164BESA+ is a 4.096V series voltage reference that holds its output to ±0.12% initial accuracy with a 10ppm/°C temperature coefficient — tight enough to feed the reference input of a 16-bit SAR ADC without an external trim pot, provided the system calibration budget accounts for the 4.096V full-scale.
Output drive and quiescent budget for mixed-signal boards
Rated for 5 mA output current with a 120µA supply draw — the reference can bias the reference input of multiple converters and a small buffer amplifier while keeping the total current budget under 130 µA, which matters for loop-powered transmitters or battery-backed instrumentation that runs continuously. Input voltage range spans 4.296 V to 12.6 V — the 4.096 V output stays in regulation as long as the input rail stays at least 200 mV above the output, so a 5 V logic rail or a 12 V unregulated supply both work without a separate pre-regulator.
Active lifecycle and compliance for BOM planning
Supplied in tube format — the 8-SOIC parts are delivered in anti-static tubes, which suits bench-level assembly and small-batch production runs where tape-and-reel handling adds setup overhead.
