8-bit Dual Digital Pot With Independent Reference Inputs

The CAT512 is a dual 8-Bit Memory DAC designed as an electronic replacement for mechanical potentiometers and trim pots. Intended for final calibration of products such as camcorders, fax machines and cellular tele- phones on automated high volume production lines and systems capable of self calibration, it is also well suited for applications were equipment requiring periodic ad- justment is either difficult to access or located in a hazardous environment. The CAT512 offers 2 independently programmable DACs each having its own reference inputs and each capable of rail to rail output swing. Output settings, stored 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 DACs output. Control of the CAT512 is accomplished with a simple 3 wire serial Interface A Chip Select pin allows several CAT512 's to share a common serial Interface and com- munications back to the host controller is via a single serial data line thanks to the CAT512s Tri-Stated Data Output pin. A RDY/BSYoutput working in concert with an internal low voltage detector signals proper operation of EEPROM Erase/Write cycle. The CAT512 operates from a single 35 volt power supply. The high voltage required for EEPROM Erase/ Write operations is generated on-chip. The CAT512 is available in the 0C to 70C Commercial and 40C to +85C Industrial operating temperature ranges and offered in 14-pin plastic DIP and Surface mount packages. By Catalyst Semiconductor
