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 highimpedance
photodiode and charge sense
applications. Additionally, built-in EMI 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.
