OA1MPA, OA2MPA, OA4MPA High precision low-power CMOS op amp Datasheet - production data Energy saving Quad (OA4MPA) Single (OA1MPA) Guaranteed operation on low-voltage battery Applications Wearable Fitness and healthcare SC70-5 QFN16 3x3 Medical instrumentation Dual (OA2MPA) Description The OA1MPA, OA2MPA, OA4MPA series of single, dual, and quad operational amplifiers offer low-voltage operation, rail-to-rail input and output, DFN8 2x2 MiniSO-8 and excellent precision (V lower than 200 V at io 25 C). These low power op amps benefit from Features STMicroelectronics 5 V CMOS technology and offer an excellent speed/power consumption ratio Low offset voltage: 200 V max. (150 kHz typical gain bandwidth) while consuming Low power consumption: 10 A at 5 V less than 14 A at 5 V. The OA1MPA, OA2MPA, Low supply voltage: 1.5 V to 5.5 V OA4MPA series also feature an ultra-low input bias current. Gain bandwidth product: 150 kHz typ. The OA1MPA, OA2MPA, OA4MPA are Low input bias current: 1 pA typ. respectively the single, dual and quad operational Rail-to-rail input and output amplifier versions and are housed in the smallest EMI hardened operational amplifiers industrial package. High tolerance to ESD: 4 kV HBM The OA1MPA, OA2MPA, OA4MPA family is the Extended temperature range: -40 to +125 C ideal choice for wearable, fitness and healthcare applications. Benefits High precision without calibration Table 1.
