Product Details

describe:

The OPAx348 family of amplifiers are single-supply, low-power, CMOS operational amplifiers. The OPAx348 family features 1 MHz extended bandwidth and 45 μA supply current for low power applications using a single 2.1 V to 5.5 V supply.

A low supply current of 45 μA and an input bias current of 0.5 pA make the OPAx348 family the best choice for low power applications such as smoke detectors and other high impedance ADR03AKSZ-REEL7 sensors.

The OPA348 is available in tiny 5-lead SC70 (SOT), 5-lead SOT-23 (SOT) and 8-lead SO (SOIC) packages. The OPA2348 is available in 8-pin SOT-23 (SOT) and 8-pin SO (SOIC) packages, and the OPA4348 is available in space-saving 14-pin TSSOP and 14-pin SO (SOIC) packages. An extended temperature range of –40°C to +125°C over all supply voltages provides design flexibility.
