PRECISION 4.096 VOLT LOW KNEE CURRENT
VOLTAGE REFERENCE
ZRC400
ISSUE 3 - MARCH 1998
DEVICE DESCRIPTION
FEATURES
Small outline SOT23 , SO8 and TO92
style packages
The ZRC400 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, as well as packages for
through hole requirements.
•
No stabilising capacitor required
Low knee current, 18µA typical
Typical TC 30ppm/°C
•

•
•
•
Typical slope resistance 0.4Ω
± 3%, 2% and 1% tolerance
Industrial temperature range
Operating current 23µA to 5mA
The ZRC400 design providesa stable voltage
without an external capacitor and is stable
with capacitive loads. The ZRC400 is
recommended for operation between 23µA
and 5mA and so is ideally suited to low
power and battery powered applications.
Transient response, stable in less than
10µs
Optional extended current range
•
Excellent performance is maintained to an
absolute maximum of 25mA, however the
rugged design and 20 volt processing allows
the reference to withstand transient effects
and currents up to 200mA. Superior
switching capability allows the device to
reach stable operating conditions in only a
few microseconds.
APPLICATIONS
Battery powered and portable
equipment.
•
Instrumentation.
•
Test equipment.
•
Metering and measurement systems.
