Offering 0.7-Ohm of On-Resistance, this low-voltage family of devices provides users with near-zero distortion, and high integrity signal routing for such end-products as portable phones, Global Positioning Systems, Portable Digital Assistants, and mobile computing systems. Pericom implements this new family of SPDT and SPST switches in low-power sub-micron CMOS technology, which helps extend the battery life of portable devices.
"We continue expanding our analog switch portfolio to leverage our digital switch design expertise," explained Refugio Jones, Pericom Product Marketing Manager. "Portable or handheld systems developers can now use these new sub 1-Ohm analog devices anywhere there's a need for low distortion switching. This new family of switches will perform at a level equal to or better than our competition. Portable device architects looking to switch voice and audio signals will find this family very useful." Jones estimated the market for these analog switches exceeds $20 million annually and is driven by handheld mobile communications, which is growing at about 10 to 15 percent each year.
"Designers really appreciate devices that save space while offering superior performance," Jones said, "and they can do so by specifying our sub 1-Ohm SOTiny Analog Switch family." For example, Pericom's PI5A4624 is an improved alternative to Maxim's MAX4624 device, while the PI5A3159 boasts 0.7-Ohm, low distortion performance as compared with Fairchild's NC7SB3157. Specifically, Pericom's newest family outperforms the competition with lower on-resistance, improved charge injection, and better On-resistance flatness. "Pericom continues to be a customer service driven company, which is yet another reason why customers will benefit when partnering with us," Jones added.
By using smaller SOT-23 packaging, Pericom offers design advantages. "Designers want to maximize board space because they're developing smaller and smaller mobile communications products," Jones noted, "Our selection of SOTiny packaging helps to keep board size to a minimum and improves the cost-effectiveness of the end systems." These devices are also used as simple fixes to minute I/O oversights in ASIC or complex logic designs and often used in conjunction with Pericom SOTiny Gates.
Key Features of the 1-Ohm SOTiny Analog Switch Family -- Less than 1-Ohm of On-resistance for high integrity (low distortion) signal routing with (0.7-Ohms with a 5V supply; 1.4-Ohms with a 3V supply; and 0.05-Ohm resistance flatness. -- Excellent isolation and unwanted signal rejection (off isolation: -57dB at 1MHz; crosstalk: -57dB at 1MHz). -- Wide power supply operation (fully specified to operate on 1.8V to 5V supplies; low current drain: 1 microampere (max.).
