3 Description

The TLV521 350 nA nanopower op amp offers

optimum price performance in TI's nanopower family

of operational amplifiers. The TLV521 has a carefully

designed CMOS input stage enabling very low Ibias

would otherwise impact sensitive applications like

Megaohm resistance, high-impedance photodiode

and charge sense situations. Additionally, built-in EMI

protection reduces sensitivity to unwanted RF signals

from sources like mobile phones and RFID readers.

The TLV521 is offered in the 5-pin SC70 package,

and operates from –40°C to 125°C.
