Single-layer multitouch capacitive-touchscreen ICs are industry’s first

Based on the company’s proprietary single-layer multitouch projected capacitive-touchscreen technology, the LDS7000 and LDS7001 touchscreen controller ICs are offered as the first of their kind to offer a true single-layer solution, not requiring crossover isolation points that other solutions require, yet still maintaining full multitouch capability. According to the company, this enables a lower-cost total solution that does not sacrifice features or performance. Typical applications include mobile handsets, personal navigation devices, and handheld gaming platforms with screen sizes up to 5 in.

The LDS7000 and LDS7001 feature up to 30 and 35 sensor channels, respectively. Both controllers operate at a speedy 8-ms data rate for quick response to touch inputs to improve the user’s experience and enable advanced applications that require fast response times.

The IDT LDS7000 family’s algorithms eliminate undesired multitouch ghosting, providing accurate individual x and y coordinates in dual-touch mode, a critical requirement for customers using host-interpreted custom gestures to differentiate their end products. The devices’ analog front-end design provides a high level of noise rejection performance that negates the need for a separate touchscreen shield layer for most applications, lowering the overall solution cost even further.

The LDS7000 is available in a 5 x 5-mm 40-pin TQFN package, while the LDS7001 is housed in a 6 x 6-mm 48-pin TQFN package. (Ea/10,000: LDS7000, $2.50, LDS7001, $2.95 — samples available now.)
