DESCRIPTION
APPLICATIONS
Battery/Solar-Powered Instrumentation
Portable Gas Monitors
Low-voltage Signal Processing
Nanopower Active Filters
Wireless Remote Sensors
Battery-powered Industrial Sensors
Active RFID Readers
Powerline or Battery Current Sensing
Handheld/Portable POS Terminals
The TS1001 is the industry’s first sub-1µA supply
current, precision CMOS operational amplifier rated to
operate at a nominal supply voltage of 0.8V. Optimized
for ultra-long-life battery-powered applications, the
TS1001 is an operational amplifier in the “NanoWatt
Analog™” high-performance analog integrated circuits
portfolio. The TS1001 exhibits a typical input offset
voltage of 0.5mV, a typical input bias current of 25pA,
and rail-to-rail input and output stages. The TS1001
can operate from single-supply voltages from 0.65V to
2.5V.
The TS1001’s combined features make it an excellent
choice in applications where very low supply current
and low operating supply voltage translate into very
long equipment operating time. Applications include:
nanopower active filters, wireless remote sensors,
battery and powerline current sensors, portable gas
monitors, and handheld/portable POS terminals.
The TS1001 is fully specified at V
DD
= 0.8V and over
the industrial temperature range (−40°C to +85°C) and
is available in a PCB-space saving 5-lead SC70
surface-mount package.

Electrical and thermal stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These
are stress ratings only and functional operation of the device at these or any other condition beyond those indicated in the operational sections
of the specifications is not implied. Exposure to any absolute maximum rating conditions for extended periods may affect device reliability and
lifetime.
