DESCRIPTION
The TS1005 is a 1.3µA supply current, precision
CMOS operational amplifier designed to operate over
a supply voltage range from 0.8V to 5.5V with a
GBWP of 20kHz. Fully specified at 1.8V, the TS1005
is optimized for ultra-long-life battery-powered
applications. The TS1005 is the fifth operational
amplifier in the “NanoWatt Analog™” high-
performance analog integrated circuits portfolio. The
TS1005 exhibits a typical input bias current of 2pA,
and has rail-to-rail input and output stages.
APPLICATIONS
Battery/Solar-Powered Instrumentation
Portable Gas Monitors
Low-voltage Signal Processing
Micropower Active Filters
Wireless Remote Sensors
Battery-powered Industrial Sensors
Active RFID Readers
Powerline or Battery Current Sensing
Handheld/Portable POS Terminals
The TS1005’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 TS1005 is fully specified over the industrial
temperature range (−40°C to +85°C) and is available
in a PCB-space saving 5-lead SC70 and SOT23
packaging.
