DESCRI PTI O N
The LX1004 Micropower Voltage References
are two terminal bandgap reference diodes designed
and optimized for accurate low power operation in
portable
and
other
power
sensitive
systems.
Operating currents are guaranteed from as low as
10A up to 20mA giving designers a great deal of
flexibility in optimizing power consumption, noise
and ultimate application performance. The LX1004
is available in fixed 1.2V and 2.5V reference
values.
Process and circuit design optimization provide
for high accuracy with initial tolerance values of
±4mV and ±20mV, respectively. Complementing
their initial accuracy, the bandgap reference is
temperature
compensated
to
deliver
20ppm
performance over the 0° to 70°C operating
temperature range.
The LX1004 from Linfinity is a pin for-pin
replacement for the LT1004 and LM385 families
of voltage references.
