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 –40°C to 125°C.
