DEVICE DESCRIPTION
•
•
•
•
•
•
No stabilising capacitor required
The ZRA400 uses a bandgap circuit design to
achieve a precision micropower voltage
reference of 4.096 volts. The device is available
in small outline surface mount packages, ideal
for applications where space saving is
important.
Typical TC 15ppm/°C
Typical slope resistance 0.55Ω
± 3%, 2% and 1% tolerance
Industrial temperature range
Operating current 50µA to 5mA
The ZRA400 design provides a stable voltage
withoutanexternal capacitorandisstablewith
capacitive loads.
recommended for operation between 50µA
and 5mA and so is ideally suited to low power
and battery powered applications.
The ZRA400 is

Excellent performance is maintained to a
suggested absolute maximum of 25mA,
however the rugged design and 20 volt
processing allows the reference to withstand
transient effects and currents up to 200mA.
Superiorswitchingcapabilityallowsthedevice
to reach stable operating conditions in only a
few microseconds.
