3 Description
These micropower, two-terminal, band-gap voltage
references operate over a 10-μA to 20-mA current
range and feature exceptionally low dynamic
impedance and good temperature stability. On-chip
trimming provides tight voltage tolerance. The band-
gap reference for these devices has low noise and
long-term stability.
The design makes these devices exceptionally
tolerant of capacitive loading and, thus, easier to use
in most reference applications. The wide dynamic
operating temperature range accommodates varying
current supplies, with excellent regulation.
The extremely low power drain of this series makes
them useful for micropower circuitry. These voltage
references can be used to make portable meters,
regulators, or general-purpose analog circuitry, with
battery life approaching shelf life. The wide operating
current range allows them to replace older references
with tighter-tolerance parts.
