Datasheet Analog Devices MAX6520 — 数据表

19-1130; Rev 1; 7/05 50ppm/°C, SOT23, 3-Terminal,
1.2V Voltage Reference
The MAX6520 is the lowest-power 1.2V, precision,
three-terminal voltage reference offered in a SOT23-3
package. Ideal for 3V battery-powered equipment
where power conservation is critical, the MAX6520 is a
low-power alternative to existing two-terminal shunt references. Unlike two-terminal references that throw
away battery current and require an external series
resistor, the MAX6520 has a 70µA maximum supply
current (typically only 50µA) that is independent of the
input voltage. This feature translates to maximum efficiency at all battery voltages.
The MAX6520 operates from a supply voltage as low as
2.4V, and initial accuracy is ±1% for the SOT23 package. Output voltage temperature coefficient is typically only 25ppm/°C, and is guaranteed to be less
than 50ppm/°C in the SOT23 package. ____________________________Features
