Description

The OA1MPA, OA2MPA, OA4MPA series of

single, dual, and quad operational amplifiers offer

low-voltage operation, rail-to-rail input and output,

and excellent precision (Vio lower than 200 µV at

25 °C).

These low power op amps benefit from

STMicroelectronics 5 V CMOS technology and

offer an excellent speed/power consumption ratio

(150 kHz typical gain bandwidth) while consuming

less than 14 µA at 5 V. The OA1MPA, OA2MPA,

OA4MPA series also feature an ultra-low input

bias current.

The OA1MPA, OA2MPA, OA4MPA are

respectively the single, dual and quad operational

amplifier versions and are housed in the smallest

industrial package.

The OA1MPA, OA2MPA, OA4MPA family is the

ideal choice for wearable, fitness and healthcare

applications.
