All voltage values, except differential voltage are with respect to network ground terminal.
Differential voltages are the non-inverting input terminal with respect to the inverting input terminal.
Input current must be limited by a resistor in series with the inputs.
Rth are typical values.
Short-circuits can cause excessive heating and destructive dissipation.

Application information
3.1
Operating voltages
The TSB611 operational amplifier can operate from 2.7 V to 36 V. The parameters are fully
specified at 2.7 V, 12 V, and 36 V power supplies. However, parameters are very stable in
the full Vcc range. Additionally, main specifications are guaranteed in the extended
temperature range from -40 to 125 °C.
3.2
Input common-mode range
The TSB611 has an input common-mode range that includes ground. The input commonmode range is extended from (VCC-) - 0.1 V to (VCC+) - 1 V.
3.3
Rail-to-rail output
The operational amplifier's output levels can go close to the rails: 100 mV maximum below
the positive rail and 110 mV maximum above the negative rail when connected to a 10 kΩ
resistive load to VCC/2 for a power supply voltage of 36 V.
3.4
Input offset voltage drift over temperature
The maximum input voltage drift variation over temperature is defined as the offset
variation related to the offset value measured at 25 °C. The operational amplifier is one of
the main circuits of the signal conditioning chain, and the amplifier input offset is a major
contributor to the chain accuracy. The signal chain accuracy at 25 °C can be compensated
during production at application level. The maximum input voltage drift over temperature
enables the system designer to anticipate the effect of temperature variations.
The maximum input voltage drift over temperature is computed using Equation 1.
Equation 1
∆Vio
V T – Vio 25 °C
= max io
∆T
T – 25 °C
Where T = -40 °C and 125 °C.
The datasheet maximum value is guaranteed by measurements on a representative
sample size ensuring a Cpk (process capability index) greater than 2.
3.5
Long term input offset voltage drift
To evaluate product reliability, two types of stress acceleration are used:
Voltage acceleration, by changing the applied voltage
Temperature acceleration, by changing the die temperature (below the maximum
junction temperature allowed by the technology) with the ambient temperature.
The voltage acceleration has been defined based on JEDEC results, and is defined using
Equation 2.

DocID028074 Rev 1

Equation 2
AFV = e
β . V S – VU
Where:
AFV is the voltage acceleration factor
β is the voltage acceleration constant in 1/V, constant technology parameter (β = 1)
VS is the stress voltage used for the accelerated test
VU is the voltage used for the application
The temperature acceleration is driven by the Arrhenius model, and is defined in
Equation 3.
Equation 3
AFT = e
Ea

------ .

TU TS
Where:
AFT is the temperature acceleration factor
Ea is the activation energy of the technology based on the failure rate
-5
-1
k is the Boltzmann constant (8.6173 x 10 eV.K )
TU is the temperature of the die when VU is used (K)
TS is the temperature of the die under temperature stress (K)
The final acceleration factor, AF, is the multiplication of the voltage acceleration factor and
the temperature acceleration factor (Equation 4).
Equation 4
AF = AFT × AFV
AF is calculated using the temperature and voltage defined in the mission profile of the
product. The AF value can then be used in Equation 5 to calculate the number of months of
use equivalent to 1000 hours of reliable stress duration.
Equation 5
Months = AF × 1000 h × 12 months / 24 h × 365.25 days
To evaluate the op amp reliability, a follower stress condition is used where V CC is defined
as a function of the maximum operating voltage and the absolute maximum rating
(as recommended by JEDEC rules).
The Vio drift (in µV) of the product after 1000 h of stress is tracked with parameters at
different measurement conditions (see Equation 6).
Equation 6
VCC = maxVop with Vicm = VCC 2
DocID028074 Rev 1
17/24
Application information
TSB611
The long term drift parameter (ΔVio), estimating the reliability performance of the product, is
obtained using the ratio of the Vio (input offset voltage value) drift over the square root of
the calculated number of months (Equation 7).
Equation 7
∆Vio =
Vio dr ift
month s
Where Vio drift is the measured drift value in the specified test conditions after 1000 h
stress duration.
3.6
ESD structure of TSB611
The TSB611 is protected against electrostatic discharge (ESD) with dedicated diodes (see
Figure 35). These diodes must be considered at application level especially when signals
applied on the input pins go beyond the power supply rails (V CC+ or VCC-). Current through
the diodes must be limited to a maximum of 10 mA as stated in Table 1. A serial resistor or
a Schottky diode can be used on the inputs to improve protection but the 10 mA limit of
input current must be strictly observed.

Application information
Initialization time
The TSB611 has a good power supply rejection ratio (PSRR), but as with all devices, it is
recommended to use a 22 nF bypass capacitor as close as possible to the power supply
pins. It prevents the noise present on the power supply impacting the signal conditioning. In
addition, this bypass capacitor enhances the initialization time (see Figure 36 and
Figure 37).
