Description
DFN8 2x2
MiniSO-8
Features
 Low offset voltage: 200 µV max.
 Low power consumption: 10 µA at 5 V
 Low supply voltage: 1.5 V to 5.5 V
 Gain bandwidth product: 150 kHz typ.
 Low input bias current: 1 pA typ.
 Rail-to-rail input and output
 EMI hardened operational amplifiers
 High tolerance to ESD: 4 kV HBM
 Extended temperature range: -40 to +125 °C
Benefits
 High precision without calibration
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 (V_io 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.
