Input bias current is 1 µA; input offset voltage is 3 mV typical. Output current capability is 15 mA per channel.","metaTitle":"OPA861IDBVT Transconductance Amplifier, 900V/µs Slew Rate","metaDescription":"TI OPA861IDBVT transconductance op-amp: 900V/µs slew rate, 80 MHz GBW, 5.4 mA supply, SOT-23-6.
