Application information
Operating voltages
The amplifiers of the TSX56x series can operate from 3 to 16 V. The parameters are fully
specified at 3.3, 5 and 16 V power supplies. However, the parameters are very stable in the
full V
ranges from -40 to +125 ° C.
Rail-to-rail input
The TSX56x devices are built with two complementary PMOS and NMOS input differential
pairs. The devices have a rail-to-rail input, and the input common mode range is extended

needing to be rail-to-rail.
The devices are designed to prevent phase reversal.
Input offset voltage drift over temperature
The maximum input voltage drift over the temperature variation 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 effects of temperature variations.
The maximum input voltage drift over temperature is computed in
Equation 1
with T = -40 °C and 125 °C.
The datasheet maximum value is guaranteed by measurement on a representative sample
size ensuring a Cpk greater than 2.
Long-term input offset voltage drift
In a product reliability evaluation, two types of stress acceleration are usable:
●
●
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.
