The LTC
?/DIV>
1967 is a true RMS-to-DC converter that uses an
innovative delta-sigma computational technique. The ben-
efits of the LTC1967 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 LTC1967 operates with single-ended or differential in-
put signals (for EMI/RFI rejection) and supports crest fac-
tors up to 4. Common mode input range is rail-to-rail. Dif-
ferential input range is 1V
PEAK
, and offers unprecedented
linearity. The LTC1967 allows hassle-free system calibra-
tion at any input voltage.
The LTC1967 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 0.1礎(chǔ).
The LTC1967 is packaged in the space-saving MSOP pack-
age, which is ideal for portable applications.
