4.096 V precision anchor for industrial analog chains
The MAX6164AESA+: That combination — tight initial tolerance plus low drift — means the reference holds its setpoint within a few millivolts over temperature, which is the difference between a 12-bit ADC hitting its last LSB and losing a count at the cold end of the industrial band. Input range spans 4.296 V to 12.6 V, so it runs from a 5 V rail with 700 mV headroom or from a 12 V supply without a pre-regulator. Output current is 5 mA — enough to bias the reference input of a SAR ADC and its external buffer, but not a multi-channel array. Quiescent current sits at 120 µA, making it viable for loop-powered or battery-backed designs where every microamp is budgeted.
