OA1NP

Low power, rail-to-rail input and output, CMOS single op amp
  • active Active

The OA1NP, OA2NP, OA4NP series of CMOS operational amplifiers offer a low power consumption of 580 nA typical and 750 nA maximum per channel when supplied by 1.8 V. Combined with a supply voltage range of 1.5 V to 5.5 V, these features allow the OA1NP, OA2NP, OA4NP op amp series to be efficiently supplied by a coin type Lithium battery or a regulated voltage in low power applications.

The OA1NP, OA2NP, OA4NP are respectively the single, dual and quad operational amplifier versions.

The 8 kHz gain bandwidth of these devices make them ideal for wearable, fitness and healthcare and sensors signal conditioning applications.
