AS1004
Micropower Voltage Reference
Description
The AS1004 is a two-terminal precision band-gap voltage
reference with a low turn-on current of 10
μ
A.
Emulating a 1.235 V zener diode, the AS1004 operates more
than three orders of magnitude of output current with minute
output impedance and guaranteed stability. With an initial
tolerance of
±
4 mV and guaranteed temperature perfor-
mance, it is ideal for precision instrumentation, especially in
low power applications. Being a low-voltage reference, the
AS1004 is also well-suited as a reference for low-voltage
power supply applications, especially in power supplies
intended for low-voltage logic systems, laptop computers
and other portable or battery operated equipment.
The AS1004 is pin-for-pin compatible with the LT1004 and
the LM385 and offers improved specifications over both the
LM385 and the MP5010. It is also available as a 2.5 V
reference with a guaranteed start-up current of 20
μ
A.
