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
of 1 pA, thereby reducing IBIAS and IOS errors that
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 –40Β°C to 125Β°C.
