3 Description

The TLV522 500 nA dual, nanopower op amp offers

optimum price performance in TI's nanopower family

of operational amplifiers. The TLV522 provides 8 kHz

of gain bandwidth from 500 nA of quiescent current,

making it well suited for battery powered applications

found in building automation and remote sensing

nodes. Its CMOS input stage enables very low IBIAS,

reducing errors commonly introduced in Megaohm

feedback

resistance

topologies

such

as

applications.

Additionally,

built-in

protection

reduces sensitivity to unwanted RF signals from

sources like mobile phones, WiFi, radio transmitters

and RFID readers.

The TLV522 is offered in the 8-pin VSSOP (MSOP)

package, and operates from –40°C to 125°C.
