LT6654
SOT-23 Precision Wide
Supply High Output Drive
Low Noise Reference
DESCRIPTION
The LT^®6654 is a family of small precision voltage ref-
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 specified 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_P-P noise minimizes measurement uncertainty.
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.
