Low power: 580 nA typ. per channel at 25 C at Combined with a supply voltage range of 1.5 V to V = 1.8 V CC 5.5 V, these features allow the OA1NP, OA2NP, Low supply voltage: 1.5 V - 5.5 V OA4NP op amp series to be efficiently supplied by a coin type Lithium battery or a regulated Unity gain stable voltage in low power applications. Rail-to-rail input and output The OA1NP, OA2NP, OA4NP are respectively the Gain bandwidth product: 8 kHz typ. single, dual and quad operational amplifier Low input bias current: 5 pA max at 25 C versions. High tolerance to ESD: 2 kV HBM The 8 kHz gain bandwidth of these devices make Industrial temperature range: -40 C to +85 C them ideal for wearable, fitness and healthcare and sensors signal conditioning applications. Benefits 42 years of typical equivalent lifetime (OA1NP) if supplied by a 220 mAh coin type Lithium battery Table 1.
