  • 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.

    Key Features

    • Low power: 580 nA typ. per channel at 25 °C at VCC= 1.8 V
    • Low supply voltage: 1.5 V - 5.5 V
    • Unity gain stable
    • Rail-to-rail input and output
    • Gain bandwidth product: 8 kHz typ.
    • Low input bias current: 5 pA max at 25 °C
    • High tolerance to ESD: 2 kV HBM
    • Industrial temperature range: -40 °C to +85 °C
    • Benefits
      • 42 years of typical equivalent lifetime (OA1NP) if supplied by a 220 mAh coin type Lithium battery
      • Tolerance to power supply transient drops
      • Accurate signal conditioning of high impedance sensors
      • Fast desaturation
