DESCRIPTION

The TS1002 and the TS1004 are the industry’s first

and only dual and quad single-supply, precision

CMOS operational amplifiers fully specified to operate

at 0.8V while consuming less than 0.6µA supply

current per amplifier. Optimized for ultra-long-life

battery-powered applications, the TS1002 and the

TS1004 join Touchstone’s TS1001 operational

amplifier

in

the

“NanoWatt

Analog™”

high-

performance analog integrated circuits portfolio. Both

op amps exhibit a typical offset voltage of 0.5mV, a

typical input bias current of 25pA, and rail-to-rail input

and output stages. The TS1002 and the TS1004 can

operate from single-supply voltages from 0.65V to

2.5V.

The TS1002/TS1004’s combined features make

either 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 TS1002 and the TS1004 are fully specified at

VDD = 0.8V and over the industrial temperature

range (−40°C to +85°C). The TS1002 is available in

PCB-space

saving

8-lead

MSOP

surface-mount

packages. The TS1004 is available in a 14-pin

TSSOP package.
