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.
