Advanced Linear Devices ALD7555 and ALD7556 single and dual CMOS analog RC timers offer improved performance, exceeding other 7555 and 7556 timers on the market in terms of accuracy and stability. The combination of low power and speed gives mobile and handheld devices access to a low cost alternative that was previously unavailable. The Advanced Linear Devices ALD7555 and ALD7556 allow timers to now be used in small battery operated platforms, which was not previously possible. These RC timers can be used in place of a microprocessor or crystal in many cases, simplifying the design. These Advanced Linear Devices products supply current for low power applications and have the low supply current on the market. The ALD7555 and ALD7556 also provide reduced timing error. The reduction of current is 50% of any other low power CMOS timer currently in the market. These RC timers improve repeatability and speed for precise and accurate performance. These RC timers also feature improved drift with temperature of only 10 ppm per degree C and improved drift with supply voltage. The ALD7555 and ALD7556 are ideal for use in a variety of applications, including battery technology, power supplies, gaming, and handheld wireless.
