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.
