DESCRIPTION
The TS3002 is the industry’s first and only single-
supply CMOS oscillator fully specified to operate at
1V while consuming a 1µA supply current at an
output frequency of 25kHz. This oscillator is compact,
easy-to-use, and versatile. Optimized for ultra-long
life, battery-powered applications, the TS3002 is
Touchstone’s first oscillator in the “NanoWatt
Analog™” high-performance analog integrated
circuits portfolio. The TS3002 can operate from
single-supply voltages from 0.9V to 1.8V.
Requiring only a resistor and a capacitor to set the
output frequency, the TS3002 represents a 66%
reduction in pcb area and a factor-of-10 reduction in
power consumption over other CMOS-based
integrated circuit oscillators. When compared against
industry-standard 555-timer-based products, the
TS3002 offers up to 93% reduction in pcb area and
four orders of magnitude lower power consumption.
The TS3002 is fully specified over the -40°C to +85°C
temperature range and is available in a low-profile, 8-
pin 2x2mm TDFN package with an exposed back-
side paddle.
