Component qualification in accordance with JEDEC and industry  
standards to ensure reliable operation over an extended  
temperature range. This includes, but is not limited to, Highly  
Accelerated Stress Test (HAST) or biased 85/85, temperature  
cycle, autoclave or unbiased HAST, electromigration, bond  
intermetallic life, and mold compound life. Such qualification  
testing should not be viewed as justifying use of this component  
beyond specified performance and environmental limits.

The TLC2252 and TLC2254 are dual and  
quadruple operational amplifiers from Texas  
Instruments. Both devices exhibit rail-to-rail  
output performance for increased dynamic range  
in single- or split-supply applications. The  
TLC225x family consumes only 35 µA of supply  
current per channel. This micropower operation  
makes them good choices for battery-powered  
applications. The noise performance has been  
dramatically improved over previous generations  
of CMOS amplifiers. Looking at Figure 1, the  
TLC225x has a noise level of 19 nV/√Hz at 1kHz;  
four times lower than competitive micropower  
solutions.

The TLC225x amplifiers, exhibiting high input  
impedance and low noise, are excellent for  
small-signal conditioning for high-impedance  
sources, such as piezoelectric transducers.  
Because of the micropower dissipation levels,  
these devices work well in hand-held monitoring  
and remote-sensing applications. In addition, the  
rail-to-rail output feature with single or split

supplies makes this family a great choice when interfacing with analog-to-digital converters (ADCs). For  
precision applications, the TLC225xA family is available and has a maximum input offset voltage of 850 µV. This  
family is fully characterized at 5 V and 5 V.
