Description
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.
 42 years of typical equivalent lifetime (OA1NP)
if supplied by a 220 mAh coin type Lithium
battery
