Active production precision reference — 10V fixed, ±0.05%
The MAX876BESA+: Output current is rated at 10 mA, enough to drive the reference input of most SAR or delta-sigma converters without an external buffer. Supply current is a modest 700 µA, so it won't burn a significant share of the power budget in a multi-channel data-acquisition system.
Noise floor and deployment context
The input voltage range is 12 V to 18 V, giving about 2 V of headroom above the 10 V output — enough for a regulated 12 V or 15 V rail. The series topology means the output is low-impedance and can source or sink small load transients without the droop a shunt reference would show.
