Milpitas, Calif. Intersil Corp. has introduced the ISL22511 and ISL22512 devices, which the company claims are the industry's smallest non-volatile pushbutton digitally-controlled potentiometers (DCPs). The ISL22511/12 devices are housed in micro-QFN packaging (2.1 x 1.6 mm) and are claimed to be 25% smaller than their nearest competitor.
With an easy-to-use pushbutton interface, the ISL22511 and ISL22512 can operate independently from a microcontroller. These devices offer an automated store feature, eliminating the need for an extra step or microcontroller to activate the "store" function. Offering multiple modes, one mode activates the auto-store mode and another keeps manual-store and activate wiper storage on command.
Both devices also feature a user-activated, power-saving shutdown mode that prevents additional current from flowing through the DCP when initiated. They are rated for use up to +125°C.
Pricing: The ISL22511 in a 10-lead micro-TQFN package is priced at $1.18 each, and in an 8-lead SOIC package at $1.16 each. The ISL22512 in a 10-lead micro-TQFN package is priced at $0.75 each and in an 8-lead SOIC package at $0.73 each. All in quantities of 1,000.
Availability: Both devices are available now.
