The TS1003 is the industry’s first sub-1µA supply
current, precision CMOS operational amplifier fully
specified to operate over a supply voltage range from
0.8V to 5.5V. Fully specified at 1.8V, the TS1003 is
optimized for ultra-long-life battery powered
applications. The TS1003 is the fourth operational
amplifier in the “NanoWatt Analog™” high-
performance analog integrated circuits portfolio. The
TS1003 exhibits a typical input bias current of 2pA,
and has rail-to-rail input and output stages.
The TS1003’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:
micropower active filters, wireless remote sensors,
battery and powerline current sensors, portable gas
monitors, and handheld/portable POS terminals.
The TS1003 is fully specified over the industrial
temperature range (−40°C to +85°C) and is available
in either a PCB-space saving 5-lead SC70 or a 5-lead
SOT23 packaging.

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.
