THEORY OF OPERATION  
The TS1005 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 TS1005 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 TS1005’s VOS value and/or the  
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 TS1005 output stages voltage swings within  
3.5mV from the rails at 1.8V 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  
TS1005 swings within 30mV of VDD and within 13mV  
of VSS (or GND).  
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.  
Depending on the 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  
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.  
often required. As shown in Figure 2, the simplest  
way to achieve this objective is to use an RC filter at  
the noninverting terminal of the TS1005. If additional  
attenuation is needed, a two-pole Sallen-Key filter  
can be used to provide the additional attenuation as  
shown in Figure 3.  
The circuit in Figure  
1
illustrates  
a
typical  
implementation used to amplify the output of an  
oxygen detector. The TS1005 makes an excellent  
choice for this application as it only draws 1.3µA of  
supply current and operates on supply voltages  
For best results, the filter’s cutoff frequency should  
be 8 to 10 times lower than the TS1005’s crossover  
frequency. Additional operational amplifier phase  
margin shift can be avoided if the amplifier  
bandwidth-to-signal bandwidth ratio is greater than  
8.  
The design equations for the 2-pole Sallen-Key low-  
pass filter are given below with component values

down to 0.8V. With the components shown in the  
figure, the circuit consumes less than 1.4μA of  
supply current ensuring that small form-factor single-  
or button-cell batteries (exhibiting low mAh charge  
ratings) could last beyond the operating life of the  
oxygen sensor. The precision specifications of the  
TS1005, such as its low offset voltage, low TCVOS,  
low input bias current, high CMRR, and high PSRR  
are other factors which make the TS1005 an  
excellent choice for this application. Since oxygen  
sensors typically exhibit an operating life of one to  
two years, an oxygen sensor amplifier built around a  
TS1005 can operate from a conventionally-available  
single 1.5-V alkaline AA battery for over 145 years!  
At such low power consumption from a single cell,  
the oxygen sensor could be replaced over 75 times  
before the battery requires replacing!

determined empirically was 1.8V. The oscilloscope  
capture shown in Figure 6 illustrates a typical  
transient response obtained with a CLOAD = 100pF  
and an RISO = 120k. Note that as CLOAD is  
increased a smaller RISO is needed for optimal  
transient response.  
The two resistors labeled R1 should be closely  
matched to each other as well as both resistors  
labeled R2 to ensure acceptable common-mode  
rejection performance.  
Resistor networks ensure the closest matching as  
well as matched drifts for good temperature stability.  
Capacitor C1 is included to limit the bandwidth and,  
therefore, the noise in sensitive applications. The  
value of this capacitor should be adjusted depending  
on the desired closed-loop bandwidth of the  
instrumentation amplifier. The RC combination  
creates a pole at a frequency equal to 1/(2π×R1C1).  
If the AC-CMRR is critical, then a matched capacitor  
to C1 should be included across the second resistor  
labeled R1.

Because the TS1005 accepts rail-to-rail inputs, the  
input common mode range includes both ground  
and the positive supply of 1.5V. Furthermore, the  
rail-to-rail output range ensures the widest signal  
range possible and maximizes the dynamic range of  
the system. Also, with its low supply current of  
1.3μA, this circuit consumes a quiescent current of  
only ~2.7μA, yet it still exhibits a 2-kHz bandwidth at  
a circuit gain of 2.

In the event that an external RLOAD in parallel with

Driving Capacitive Loads  
While the TS1005’s internal gain-bandwidth product  
is 20kHz, it is capable of driving capacitive loads up  
to 50pF in voltage follower configurations without  
any additional components. In many applications,  
however, an operational amplifier is required to drive  
much larger capacitive loads. The amplifier’s output  
impedance and a large capacitive load create  
additional phase lag that further reduces the  
amplifier’s phase margin. If enough phase delay is  
introduced, the amplifier’s phase margin is reduced.  
The effect is quite evident when the transient  
response is observed as there will appear noticeable  
peaking/ringing in the output transient response.

R3:  
Although optimized for use as an operational  
amplifier, the TS1005 can also be used as a rail-to-  
rail I/O comparator as illustrated in Figure 7.  
R3 = 10Mꢀ  
Calculating a value for R1 is given by the following  
expression:  
R1 = R3 x (VHYB/VDD)  
Substituting VHYB=100mV, VDD=3.0V, and R3=10Mꢀ  
into the equation above yields:  
R1 = 333kꢀ  
The following expression was then used to calculate  
a value for R2:  
Figure 7: A MicroWatt Analog Comparator with User-  
Programmable Hysteresis.  
R2 = 1/[VHI/(VREF x R1) – (1/R1) – (1/R3)]  
External hysteresis can be employed to minimize the  
risk of output oscillation. The positive feedback  
circuit causes the input threshold to change when  
the output voltage changes state. The diagram in  
Figure 8 illustrates the TS1005’s analog comparator  
Substituting VHI = 2.1V, VREF = 1.5V, R1 = 333k,  
and R3 = 10Minto the above expression yields:  
R2 = 909kꢀ  
Printed Circuit Board Layout Considerations  
Even though the TS1005 operates from a single  
0.8V to 5.5V power supply and consumes very little  
supply current, it is always good engineering  
practice to bypass the power supplies with a 0.1μF  
ceramic capacitor placed in close proximity to the  
VDD and VSS (or GND) pins.

analog circuit by decreasing the amount of stray  
capacitance that could be introduced at the op amp's  
inputs and outputs. Excess stray capacitance can  
easily couple noise into the input leads of the op  
amp and excess stray capacitance at the output will  
add to any external capacitive load. Therefore, PC  
board trace lengths and external component leads  
should be kept a short as practical to any of the  
TS1005’s package pins. Second, it is also good  
engineering practice to route/remove any analog  
ground plane from the inputs and the output pins of  
the TS1005.  
The design of an analog comparator using the  
TS1005 is straightforward. In this application, a 3.0V  
power supply (VDD) was used and the resistor divider  
network formed by RD1 and RD2 generated a  
convenient reference voltage (VREF) for the circuit at  
½ the supply voltage, or 1.5V, while keeping the  
current drawn by this resistor divider low. Capacitor  
C1 is used to filter any extraneous noise that could  
couple into the TS1005’s inverting input.  
In this application, the desired hysteresis band was  
set to 100mV (VHYB) with a desired high trip-point  
(VHI) set at 2.1V and a desired low trip-point (VLO)  
set at 2.0V.  
Since the TS1005 is a low supply current amplifier  
(1.3µA, typical), it is desired that the design of an  
analog comparator using the TS1005 should also  
use as little current as practical. The first step in the
