DESCRIPTION
The TS3001 is a 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 TS3001 joins Touchstone’s TS3002
CMOS oscillator in the “NanoWatt Analog™” high-
performance analog integrated circuits portfolio. The
TS3001 can operate from single-supply voltages from
0.9V to 1.8V.
Requiring only a resistor to set the output frequency,
the TS3001 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 TS3001 offers up to 93%
reduction in pcb area and four orders of magnitude
lower power consumption.
The TS3001 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.
