Shunt reference with a wide adjustable window
The MAX8515AEZK+T: It references a shunt topology, meaning it operates like a Zener diode but with a precision bandgap core — the external resistor sets the bias current, and the reference regulates the cathode voltage to the programmed value. Output is adjustable from a 0.6 V minimum up to 18 V maximum, driven by two external resistors. The 20 mA output current capability and 4 mA minimum cathode current define the operating window — the external bias resistor must supply at least 4 mA to keep the shunt in regulation at all load conditions.
Tolerance and temperature grade for the BOM
Initial output tolerance is ±0.5%, which is a mid-grade precision level — adequate for a 12-bit ADC reference or a comparator threshold where 1% system accuracy is the target.
Active lifecycle and compliance
No pin-compatible second-source is listed on the manufacturer's cross-reference for this exact order code.
