DESCRIPTION

The LT

erences that offers high accuracy, low noise, low drift,

low dropout and low power. The LT6654 operates from

voltages up to 36V and is fully speciﬁ ed from –55°C to

125°C. A buffered output ensures ±10mA of output drive

with low output impedance and precise load regulation.

These features, in combination, make the LT6654 ideal

for portable equipment, industrial sensing and control,

and automotive applications.

The LT6654 was designed with advanced manufactur-

ing techniques and curvature compensation to provide

10ppm/°C temperature drift and 0.05% initial accuracy.

Low thermal hysteresis ensures high accuracy and

1.6ppm

Since the LT6654 can also sink current, it can operate

as a low power negative voltage reference with the same

precision as a positive reference.

The LT6654 references are offered in 6-lead SOT-23

package and an 8-lead LS8 package. The LS8 is a 5mm

× 5mm surface mount hermetic package that provides

outstanding stability.
