RDC-19220/2/4 SERIES
16-BIT MONOLITHIC TRACKING RESOLVER
(LVDT)-TO-DIGITAL CONVERTERS
DESCRIPTION
The RDC-19220 Series of converters are low-cost, versatile, 16-bit
monolithic, state-of-the-art Resolver(/LVDT)-to-Digital Converters.
These single-chip converters are available in small 40-pin DDIP, 44-
pin J-Lead, and 44-pin MQFP packages and offer programmable fea-
tures such as resolution, bandwidth and velocity output scaling.
Resolution programming allows selection of 10-, 12-, 14-, or 16-bit,
with accuracies to 2.3 min. This feature combines the high tracking
rate of a 10-bit converter with the precision and low-speed velocity
resolution of a 16-bit converter in one package.
The velocity output (VEL) from the RDC-19220 Series, which can be
used to replace a tachometer, is a 4 V signal (3.5 V with the +5 V only
option) referenced to ground with a linearity of 0.75% of output voltage.
The full scale value of VEL is set by the user with a single resistor.
RDC-19220 Series converters are available with operating tempera-
ture ranges of 0° to +70°C, -40° to +85°C and -55° to +125°C. Military
processing is available.
