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 industrial temperature range (−40°C to +85°C)

and is available in a PCB-space saving 5-lead SC70

surface-mount package.
