The shunt topology means it operates as a two-terminal device — it sinks current through an external resistor from a supply rail, with no separate power pin. This makes it a drop-in for designs that already use a shunt reference footprint, common in ADC bias and DAC scaling circuits. For a 12-bit ADC with a 4.096 V reference, that drift contributes less than 1 LSB of error across the temperature band, assuming the rest of the signal chain is stable. ## Noise floor and bias current limits A 30 µVp-p noise floor on a 4.096 V reference represents about 0.0007% peak-to-peak, which is adequate for 16-bit systems where the reference noise stays below 1/4 LSB. The device can source up to 30 mA from the output pin, while the minimum cathode current for regulation is 15 µA. The external bias resistor must be sized to supply the load current plus the cathode current, with enough headroom to keep the shunt in regulation across the supply voltage range. For a typical 5 V rail feeding a 10 kΩ load, a 30 Ω resistor sets the bias point correctly.","metaTitle":"Analog Devices LT1634CCZ-4.096#PBF Shunt Reference","metaDescription":"LT1634CCZ-4.096#PBF precision shunt voltage reference, 4.096V fixed output, ±0.2% tolerance, 25ppm/°C drift, TO-92-3.
