Manufacturer Part Number
zrc400r1
Description
Precision 4.096 Volt Low Knee Current Voltage Reference
Manufacturer
Zetex Semiconductors plc.
Datasheet
PRECISION 4.096 VOLT LOW KNEE CURRENT
VOLTAGE REFERENCE
ISSUE 3 - MARCH 1998
DEVICE DESCRIPTION
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.
The ZRC400 design provides a stable voltage
without an external capacitor and is stable
with capacitive loads. The ZRC400 is
recommended for operation between 23 A
and 5mA and so is ideally suited to low
power and battery powered applications.
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.
