Datasheet MAX6520 (Analog Devices) - 4

50ppm/°C, SOT23, 3-Terminal, 1.2V Voltage Reference _____________________Pin Description __________Applications Information Input Bypassing PIN NAME FUNCTION
For the best line-transient performance, decouple the 1 VIN Input Voltage input with a 0.1µF ceramic capacitor as shown in the Typical Operating Circuit. Locate the capacitor as 2 VOUT Reference Output close to the device pin as possible. Where transient performance is less important, no capacitor is neces- 3 GND Ground

sary.
Output Bypass
The MAX6520 performs well without an output decou- pling capacitor. If your application requires an output charge reservoir (e.g., to decouple the reference from +3V VIN VOUT the input of a DAC), then make sure that the total output MAX6520 1 2 capacitive load does not exceed 10nF. 3 0.1µF 0.01µF DIN CS REFAB REFC 1 2 12 11 SCLK 3 OUTA DAC 8 +3V LATCH A DAC A OUTB R R DAC 9 VIN VOUT LATCH B DAC B DATA (8) MAX6520 1 2 3 OUTC 7 DAC 2 +1.2V LATCH C DAC C 10 6 -1.2V 16-BIT SHIFT REGISTER MAX406A 3 MAX512 MAX513 4 CONTROL (8) LOUT -3V LATCH 14 4 5 7 6 RESET VDD VSS GND Figure 2.
