LT6658

Precision Dual Output, High Current,

Low Noise, Voltage Reference

FEATURES

DESCRIPTION

The

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.
