DESCRIPTION
The
LT
®
6658
is a family of precision dual output references
combining the performance of a precision voltage refer-
ence and a linear regulator that we call the Refulator™.
Both outputs are ideal for driving the reference inputs of
high resolution ADCs and DACs, even with heavy load-
ing, while simultaneously powering microcontrollers and
other circuitry. Both outputs have the same precision
specifications and track each other over temperature and
load. Each output can be configured with external resis-
tors to give an output voltage up to 6V.
Using Kelvin connections, the LT6658 typically has
0.1ppm/mA load regulation with up to 150mA load cur-
rent. A noise reduction pin is available to band-limit and
lower the total integrated noise.
Separate supply pins are provided for each output, provid-
ing an option to reduce power consumption and isolate
the buffer amplifiers. The outputs have excellent supply
rejection and are stable with 1µF to 50µF capacitors.
The LT6658 is available in a 16-lead MSOP and DFN with
an exposed pad for thermal management. Short circuit
and thermal protection help to prevent thermal overstress.
