Digitally programmable potentiometers to take over
Catalyst Semiconductor has added two new digitally programmable potentiometer (DPP) ICs to its AE2 (analogue EEPROM) mixed-signal product line.
EEPROM provides more secure MPU supervision
Catalyst Semiconductor has expanded its AE2 analogue EEPROM mixed-signal product strategy with the CAT116x series of microprocessor supervisory circuits with serial 16Kbit EEPROM.
These small, low cost 16- and 32-tap digital potentiometers come in 5- and 6-pin SC70 (2 x 2mm) and SOT23 packages.
The devices are ideal for many consumer oriented mobile applications, as well as many other space constrained applications.
Some of the functions they can perform include LED brightness control, LCD contrast adjustments, volume control, gain adjustment, and mechanical trim potentiometer replacement.
These volatile MiniPots use a two-wire up/down interface.
They operate from a 2.7 to 5.5V single supply and consume an ultralow 0.3uA of supply current (typical).
The temperature coefficient is 200ppm/C for the end-to-end resistance and 5ppm/C for the ratiometric resistance.
Glitchless switching between resistor taps ensures a smooth transition when changing wiper positions.
The Catalyst family of MiniPots is provided in three end-to-end resistance values (10, 50 and 100kohm) for maximum design flexibility.
"The introduction of the volatile MiniPots from Catalyst Semiconductor in the ultrasmall SC70 package will provide us with more competitive solutions to target the generally high volume, low cost and space conscience mobile products markets that Catalyst Semiconductor is focused on with many of our new product offerings", said Jerry Miller, Product Marketing Manager.
