OA1MPAHigh precision low-power single CMOS op amp
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 (Violower 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.
