description  
The TLV2422 and TLV2422A are dual low-voltage  
operational amplifiers from Texas Instruments.  
The common-mode input voltage range for this  
device has been extended over the typical CMOS  
amplifiers making them suitable for a wide range  
of applications. In addition, the devices do not  
phase invert when the common-mode input is  
driven to the supply rails. This satisfies most  
design requirements without paying a premium  
for rail-to-rail input performance. They also exhibit  
rail-to-rail output performance for increased  
dynamic range in single- or split-supply  
applications. This family is fully characterized at

3-V and 5-V supplies and is optimized for low-voltage operation. The TLV2422 only requires 50 µA of supply  
current per channel, making it ideal for battery-powered applications. The TLV2422 also has increased output  
drive over previous rail-to-rail operational amplifiers and can drive 600-loads for telecom applications.  
Other members in the TLV2422 family are the high-power, TLV2442, and low-power, TLV2432, versions.  
The TLV2422, exhibiting high input impedance and low noise, is excellent for small-signal conditioning for  
high-impedance sources, such as piezoelectric transducers. Because of the micropower dissipation levels and  
low-voltage operation, 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 TLV2422A is available with  
a maximum input offset voltage of 950 µV.  
If the design requires single operational amplifiers, see the TI TLV2211/21/31. This is a family of rail-to-rail output  
operational amplifiers in the SOT-23 package. Their small size and low power consumption, make them ideal  
for high density, battery-powered equipment.
