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 Touchstone’s fifth
operational amplifier in the “NanoWatt Analog™”
high-performance analog integrated circuits portfolio.
The TS1005 exhibits a typical input bias current of
2pA, and rail-to-rail input and output stages. The
TS1005 can operate from single-supply voltages from
0.8V to 5.5V.
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 package.
