AD584 Multi-Output Reference Selection

About this circuit

# AD584 Multi-Output Reference Selection ## Application This circuit uses AD584 as a multi-output precision reference so 10 V, 5 V, and 2.5 V reference nodes can be inspected from one schematic. It is useful for measurement systems that need selectable calibration references or multiple precision thresholds. ## Design Context VIN is set to 15 V and STROBE is tied high to enable the reference. The 10 V, 5 V, and 2.5 V outputs are routed to separate load resistors on the right, while VBG, CAP, and GND return to the common bottom bus for this operating-point demo. ## Expected Behavior The operating-point table should show V10 near 10 V, V5 near 5 V, and V2p5 near 2.5 V. R10 draws about 1.0 mA from the 10 V output, while the 100K loads keep the 5 V and 2.5 V outputs lightly loaded. ## Key Values - VIN: 15 V DC input supply. - STROBE: tied high to VIN. - R10: 10K load on the 10 V output. - R5 and R2P5: 100K loads on the 5 V and 2.5 V outputs. - Expected outputs: about 10 V, 5 V, and 2.5 V. ## Suggested Experiments - Change R10, R5, or R2P5 and compare how each output responds to loading. - Disable STROBE to inspect the enabled versus disabled operating point. - Use one output as an ADC reference and another as a comparator threshold in a larger circuit. ## Featured Component AD584 Voltage Reference is the multi-output reference under test. The demo highlights its enabled operating state and the three externally useful reference outputs.
