DESCRIPTION
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 Touchstone’s first
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 VDD = 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.
