DESCRIPTION
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 10µA up to 20mA giving designers
a great deal of flexibility in optimiz-
ing power consumption, noise and
ultimate application performance.
The LX1004 is available in fixed
1.2V and 2.5V reference values.
Process and circuit design optimiza-
tion 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.
