OPA2348A数据手册TI中文资料规格书

描述 Description

DESCRIPTION
The OPA348 series amplifiers are single supply, low-power, CMOS op amps in micro packaging. Featuring an extended bandwidth of 1MHz, and a supply current of 45µA, the OPA348 series is useful for low-power applications on single supplies of 2.1V to 5.5V.
Low supply current of 45µA, and an input bias current of 0.5pA, make the OPA348 series an optimal candidate for low-power, high-impedance applications such as smoke detectors 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 extended temperature range of –40°C to +125°C over all supply voltages offers additional design flexibility.FEATURES
