DTC-19300
LVDT/RVDT-TO-DIGITAL CONVERTER
DESCRIPTION
The DTC-19300 is a 12- or 14-bit
LVDT (Linear Variable Differential
Transformer)- or RVDT (Rotary
Variable Differential Transformer)-to-
digital converter which also supplies
the AC excitation to drive the LVDT.
Internal AC excitation voltage, fre-
quency, signal gain and resolution are
all programmable for optimum system
performance. Packaged in a 36-pin
hybrid, the DTC-19300 also features
Velocity (VEL) and Built-In-Test (BIT)
outputs. The three-state digital out-
puts are provided in a two byte for-
mat, for easy computer interface.
The DTC-19300 has been designed
precisely for use with an LVDT.
Inherent characteristics of the DTC-
19300, such as the input to output
phase shift, have been given con-
siderable attention. The converter’s
reference voltage is derived from,
and is in phase with, the LVDT out-
put signal. Therefore, any errors due
to the transducer’s phase shift are
virtually eliminated. Additionally, the
programmability of the DTC-19300
will accomodate a broad range of
LVDT’s.
FEATURES
Internal Oscillator:
Programmable for Voltage and
Frequency
Programmable Signal Gain
Programmable for 12- or 14-Bit
Resolution
APPLICATIONS
The DTC-19300 provides many fea-
tures previously supplied by individual
system components. Because of its
internal AC source, programmable
features, fault indicator (BIT), and
velocity output (VEL), the need for
other system circuits is minimized. The
DTC-19300 is an excellent choice for
applications using the LVDT transduc-
er for position feedback, such as mili-
tary, commercial aerospace and
industrial control systems.

Help! PCM2707 is not working properly
A year ago, a manufacturer asked me to draw a board that uses PCM2707 to output I2S. At that time, everything was normal when I tested it myself. Two days ago, I used the board I made before to assemb...

I need to disconnect the existing gprs connection in WM5 (long press the hang-up key for 3 seconds), how to do it? Thank you
As the title says. The connection to be disconnected is not the one opened by the program itself using connmanager, but any gprs connection that has been connected. How to achieve this? I have searche...
