3 Description
The LM4132 family of precision voltage references
performs comparable to the best laser-trimmed
bipolar references, but in cost-effective CMOS
technology. The key to this breakthrough is the use of
EEPROM registers for correction of curvature,
temperature coefficient (tempco), and accuracy on a
CMOS band-gap architecture allowing package-level
programming to overcome assembly shift. The shifts
in voltage accuracy and tempco during assembly of
die into plastic packages limit the accuracy of
references trimmed with laser techniques.
Unlike other LDO references, the LM4132 can deliver
up to 20 mA and does not require an output capacitor
or buffer amplifier. These advantages along with the
SOT-23 packaging are important for space-critical
applications.
Series references provide lower power consumption
than shunt references, because they do not have to
idle the maximum possible load current under no-load
conditions. This advantage, the low quiescent current
(60 µA), and the low dropout voltage (400 mV) make
the LM4132 ideal for battery-powered solutions.
The LM4132 is available in five grades (A, B, C, D
and E) for greater flexibility. The best grade devices
(A) have an initial accuracy of 0.05% with a specified
temperature coefficient of 10 ppm/°C or less, while
the lowest grade devices (E) have an initial accuracy
of 0.5% and a tempco of 30 ppm/°C.
