IDT LDS7000 and LDS7001 Touch Screen Controller ICs

Integrated Device Technology introduced the LDS7000 and LDS7001 touch screen controller IC’s. The LDS7000 and LDS7001 are optimized for IDT’s single-layer multi-touch projected capacitive touch screen technology. They do not not require cross-over isolation points like other solutions. The new ICs are sampling now. The LDS7000 is available in a 5×5 mm, 40-pin TQFN package. It is priced at $2.50 in 10,000-unit quantities. The IDT LDS7001 is available in a 6×6 mm, 48-pin TQFN package. It is priced at $2.95 in 10,000-unit quantities.
