Adjustable shunt reference — 1.233 V to 10 V output range
Its output is set with two external resistors from a minimum of 1.233 V up to 10 V, making it a flexible drop-in for any rail that needs a stable voltage threshold — ADC reference, comparator trip point, or regulator feedback bias.
±1 % tolerance and 150 ppm/°C drift — the accuracy envelope
Initial output tolerance is ±1 %, which sets the uncalibrated accuracy floor for an 8- or 10-bit ADC reference without trimming.
12 mA output, 80 µA cathode current — load and bias budgeting
The shunt can sink up to 12 mA of output current, which covers the bias for a typical microcontroller ADC or a couple of op-amp inputs. The cathode current is 80 µA — this is the minimum current needed to keep the reference in regulation, so the series resistor from the supply must be sized to deliver at least that much at the lowest supply voltage. A 1 kΩ resistor from a 5 V rail gives roughly 3.8 mA bias, well above the floor.
