DESCRIPTION
The TS3003 is a single-supply, second-generation Touchstone Semi oscillator/timer fully specified to operate at a supply voltage range of 1.55V to 5.25V while consuming less than 2.4μA(max) supply current. Requiring only a resistor to set the base output frequency (or output period) at 25kHz (or 40µs) with a 50% duty cycle, the TS3003 timer/oscillator is compact, easy-to-use, and versatile. Optimized for ultra-long life, low frequency, battery-powered/portable applications, TS3003 joins the TS3001, TS3002, TS3004, and TS3006 in Touchstone’s CMOS timer family in its “NanoWatt Analog™” series of high-performance analog integrated circuits.
