Featuring an extended bandwidth of 1MHz, and a supply current of 45 µA, the OPA348 series is useful for low-power applications on single supplies of 2.1V to 5.5V. Low supply current of 45 µA, and an input bias current of 0.5pA, make the OPA348 series an optimal candidate for low-power, high-impedance applications such as smoke de- tectors and other sensors. The OPA348 is available in the miniature SC70-5, SOT23-5 and SO-8 packages. The OPA2348 is available in SOT23-8 and SO-8 packages, and the OPA4348 is offered in space-saving TSSOP-14 and SO-14 packages. The ex- tended temperature range of –40 °C to +125°C over all supply voltages offers additional design flexibility.
