LVDT/RVDT-TO-DIGITAL CONVERTER

FEATURES

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.

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.

• 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.

• Velocity Output

• Built-In-Test Output

• Three-State, Two-Byte

Digital Output

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,
