TLV521 Operational Amplifier

Texas Instruments' 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 which enables a 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.
