M385

DESCRIPTION

The UTC M385 is a micropower voltage reference. This device

features good temperature stability and extreme low dynamic

impedance when it is operated over a 20μA to 20mA current. Low

noise and good long-term stability are achieved because the UTC

M385 bandgap reference applies only bipolar transistors and

resistors.

The UTC M385 can be used in almost any reference application

due to the exceptional tolerance of capacitive loading. This voltage

reference can be applied in portable meters, regulators, or

general-purpose analog circuitry with battery life approaching shelf

life. The wide dynamic operating range contributes to its use with

widely varying supplies with excellent regulation. The low power

drain of the UTC M385 is useful for micropower circuitry. On-chip

trimming gives it the tight voltage tolerance. Furthermore, the wide

operating current can replace older references with a tighter

tolerance.

The UTC M385 can be used in such applications, for example,

portable and battery-powered equipment, instrumentation, process

control, energy management, product testing, automotive, precision

audio components, and so on.
