IC synchro- or resolverto-digital converters with 14-bit-DIP 36 PIN,SYNCHRO-TO-DIGITAL CONVERTERS

DESCRIPTION
The SD-14590/91/92 series are high reliability synchro- or resolverto-
digital converters with 14-bit-only, 16-bit-only, or 14- or 16-bit programmable
resolution. In addition, the SD-14591 and SD-14592 are
pin-for-pin replacements for the Natel 1024 and 1026, respectively,
and many legacy products.
User-programmable resolution has been designed into the SD-14590
to increase the capabilities of modern motion control systems. The
precise positioning attained at 16 bits of resolution and fast tracking
of a 14-bit device are now available from one 36-pin double DIP
hybrid. Velocity output (VEL) from the SD-14590/91/92 is a V-based
voltage of 0 to ±3.5 VDC with a linearity to 2.0%. Output voltage is
positive for an increasing angle. The digital angle output from the SD-
14590/91/92 is a natural binary code, parallel positive logic and is
TTL/CMOS compatible. Synchronization to a computer is accomplished
via a converter busy (CB) and an inhibit (INH) input
