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.
