These micropower two-terminal band-gap voltage references operate over a 20-uA 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 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.
