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.

THEORY OF OPERATION
The TS1001 is fully functional for an input signal
from the negative supply (VSS or GND) to the
positive supply (VDD). The input stage consists of two
differential amplifiers, a p-channel CMOS stage and
an n-channel CMOS stage that are active over
different ranges of the input common mode voltage.
The p-channel input pair is active for input common
mode voltages, VINCM, between the negative supply
to approximately 0.4V below the positive supply. As
the common-mode input voltage moves closer
towards VDD, an internal current mirror activates the
n-channel input pair differential pair. The p-channel
input pair becomes inactive for the balance of the
input common mode voltage range up to the positive
supply. Because both input stages have their own
offset voltage (VOS) characteristic, the offset voltage
of the TS1001 is a function of the applied input
common-mode voltage, VINCM. The VOS has a
crossover point at ~0.4V from VDD (Refer to the VOS
vs. VCM curve in the Typical Operating
Characteristics section). Caution should be taken in
applications where the input signal amplitude is
comparable to the TS1001’s VOS value and/or the
APPLICATIONS INFORMATION
Portable Gas Detection Sensor Amplifier
Gas sensors are used in many different industrial
and medical applications. Gas sensors generate a
current that is proportional to the percentage of a
particular gas concentration sensed in an air
sample. This output current flows through a load
resistor and the resultant voltage drop is amplified.
www.DDaetpaeShnedeitn4gUo.cnomthe sensed gas and sensitivity of the
sensor, the output current can be in the range of
tens of microamperes to a few milliamperes. Gas
sensor datasheets often specify a recommended
load resistor value or a range of load resistors from
which to choose.
design requires high accuracy. In these situations, it
is necessary for the input signal to avoid the
crossover point. In addition, amplifier parameters
such as PSRR and CMRR which involve the input
offset voltage will also be affected by changes in the
input common-mode voltage across the differential
pair transition region.
The second stage is a folded-cascode transistor
arrangement that converts the input stage
differential signals into a single-ended output. A
complementary drive generator supplies current to
the output transistors that swing rail to rail.
The TS1001 output stages voltage swings within
1.2mV from the rails at 0.8V supply when driving an
output load of 100k- which provides the maximum
possible dynamic range at the output. This is
particularly important when operating on low supply
voltages. When driving a stiffer 10kload, the
TS1001 swings within 10mV of VDD and within 5mV
of VSS (or GND).
There are two main applications for oxygen sensors
– applications which sense oxygen when it is
abundantly present (that is, in air or near an oxygen
tank) and those which detect traces of oxygen in
parts-per-million concentration. In medical
applications, oxygen sensors are used when air
quality or oxygen delivered to a patient needs to be
monitored. In fresh air, the concentration of oxygen
is 20.9% and air samples containing less than 18%
oxygen are considered dangerous. In industrial
applications, oxygen sensors are used to detect the
absence of oxygen; for example, vacuum-packaging
of food products is one example.
