Micropower single op-amp for battery-operated signal chains
The output swings rail-to-rail, preserving dynamic range at low supply voltages. Input bias current is 3 pA, and input offset voltage is 550 µV.
The 20 µA quiescent current is the headline spec for this part. In a multi-channel battery monitor or a portable CO₂ detector running on a coin cell, that draw per amplifier is negligible. The trade-off is bandwidth: 500 kHz GBW and 0.23 V/µs slew rate limit the part to low-frequency signals — audio filtering, thermocouple amplification, or DC level shifting. If you need to drive a 10 kHz sine at full rail, the slew rate will distort the output; the TLV2761 is designed for the slow-and-low side of the signal chain.
