DESCRIPTION
The CAT514 is a quad 8-Bit Memory DAC designed as
an electronic replacement for mechanical potentiom-
eters and trim pots. Intended for final calibration of
products such as camcorders, fax machines and cellular
telephones on automated high volume production lines,
it is also well suited for systems capable of self calibra-
tion, and applications where equipment which is either
difficult to access or in a hazardous environment, re-
quires periodic adjustment.
The 4 independently programmable DAC's have an
output range which includes both supply rails. Output
settings, stored in non-volatile EEPROM memory, are
not lost when the device is powered down and are
automatically reinstated when power is returned. Each
output can be dithered to test new output values without
effecting the stored settings and stored settings can be
read back without disturbing the DAC’s output.
Control of the CAT514 is accomplished with a simple 3
wire serial interface. A Chip Select pin allows several
CAT514's to share a common serial interface and com-
munication back to the host controller is via a single
serial data line thanks to the CAT514’s Tri-Stated Data
Output pin. A Rdy/
Bsy
output working in concert with an
internal low voltage detector signals proper operation of
EEPROM Erase/Write cycle.
The CAT514 is available in the 0 to 70
°
C Commercial
and –40
°
C to + 85
°
C Industrial operating temperature
ranges and offered in 14-pin plastic DIP and SOIC
packages.
