Catalyst Semiconductor CAT515

The CAT515 is a quad 8-Bit Memory DAC designed as an electronic replacement for mechanical potentiometers and trim pots. The CAT515 offers 4 independently programmable DACs each having its own reference inputs and each capable of rail to rail output swing. 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.

FEATURES

s Output settings retained without power s Independent Reference Inputs s Output range includes both supply rails s Programming voltage generated on-chip s 4 independently addressable outputs s Serial µP interface s Single supply operation: 2.7V-5.5V

APPLICATIONS

s Automated product calibration. s Remote control adjustment of equipment s Offset, gain and zero adjustments in Self- Calibrating and Adaptive Control systems. s Tamper-proof calibrations.

DESCRIPTION

Intended for final calibration of products such as camcorders, fax machines and cellular telephones on automated high volume production lines and systems capable of self calibration, it is also well suited for applications were equipment requiring periodic adjustment is either difficult to access or located in a hazardous environment. Output settings, stored nonvolatile EEPROM memory, are not lost when the device is powered down and are automatically reinstated when power is returned.
