Packaging: TS1002 – 8-pin MSOP
TS1004 – 14-pin TSSOP
The TS1002 and the TS1004 are the industry’s first
and only dual and quad single-supply, precision
CMOS operational amplifiers fully specified to operate
at 0.8V while consuming less than 0.6µA supply
current per amplifier. Optimized for ultra-long-life
battery-powered applications, the TS1002 and the
TS1004 join the TS1001 operational amplifier in the
“NanoWatt Analog™” high-performance analog
integrated circuits portfolio. Both op amps exhibit a
typical offset voltage of 0.5mV, a typical input bias
current of 25pA, and rail-to-rail input and output
stages. The TS1002 and the TS1004 can operate
from single-supply voltages from 0.65V to 2.5V.
The TS1002/TS1004’s combined features make
either 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 TS1002 and the TS1004 are fully specified at
VDD = 0.8V and over the industrial temperature
range (−40°C to +85°C). The TS1002 is available in
PCB-space saving 8-lead MSOP surface-mount
packages. The TS1004 is available in a 14-pin
TSSOP 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.
