The LTC
®
1968 is a true RMS-to-DC converter that uses an
innovative delta-sigma computational technique. The ben-
efits of the LTC1968 proprietary architecture, when com-
pared to conventional log-antilog RMS-to-DC converters,
are higher linearity and accuracy, bandwidth independent
of amplitude and improved temperature behavior.
The LTC1968 operates with single-ended or differential in-
put signals and accurately supports crest factors up to 4.
Common mode input range is rail-to-rail. Differential in-
put range is 1V
PEAK
, and offers unprecedented linearity. The
LTC1968 allows hassle-free system calibration at any in-
put voltage.
The LTC1968 has a rail-to-rail output with a separate out-
put reference pin providing flexible level shifting; it oper-
ates on a single power supply from 4.5V to 5.5V. A low power
shutdown mode reduces supply current to 0.1µA.
The LTC1968 is packaged in the space-saving MSOP pack-
age, which is ideal for portable applications.
