The parameters are fully specified for 1.8 V, 3.3 V, and 5 V power supplies. However, they are very stable in the full VCC range and several characterization curves show OA1MPA, OA2MPA, and OA4MPA device characteristics at 1.5 V. In addition, the main specifications are guaranteed in the extended temperature range from -40 °C to +125 °C. 4.2 Rail-to-rail input The OA1MPA, OA2MPA, and OA4MPA devices have a rail-to-rail input, and the input common mode range is extended from VCC-- 0.1 V to VCC+ + 0.1 V. 4.3 Rail-to-rail output The output levels of the OA1MPA, OA2MPA, and OA4MPA operational amplifiers can go close to the rails: to a maximum of 40 mV below the upper rail and to a maximum of 75 mV above the lower rail when a 10 k resistive load is connected to VCC/2. 4.4 Input offset voltage drift over temperature The maximum input voltage drift over the temperature variation is defined as the offset variation related to offset value measured at 25 °C. The operational amplifier is one of the main circuits of the signal conditioning chain, and the amplifier input offset is a major contributor to the chain accuracy. The signal chain accuracy at 25 °C can be compensated during production at application level. The maximum input voltage drift over temperature enables the system designer to anticipate the effect of temperature variations. The maximum input voltage drift over temperature is computed using Equation 1. Equation 1 V io V io  T  – V io  25C  ------------ = max ------------------------------------------------T T – 25C with T = -40 °C and 125 °C. The datasheet maximum value is guaranteed by a measurement on a representative sample size ensuring a Cpk (process capability index) greater than 1.33. 16/28 DocID025992 Rev 1 OA1MPA, OA2MPA, OA4MPA 4.5 Application information Long-term input offset voltage drift To evaluate product reliability, two types of stress acceleration are used:  Voltage acceleration, by changing the applied voltage  Temperature acceleration, by changing the die temperature (below the maximum junction temperature allowed by the technology) with the ambient temperature. The voltage acceleration has been defined based on JEDEC results, and is defined using Equation 2. Equation 2 A FV = e    VS – VU  Where: AFV is the voltage acceleration factor  is the voltage acceleration constant in 1/V, constant technology parameter ( = 1) VS is the stress voltage used for the accelerated test VU is the voltage used for the application The temperature acceleration is driven by the Arrhenius model, and is defined in Equation 3. Equation 3 A FT = e Ea  1 1 ------  ------ – ------ k  T U T S Where: AFT is the temperature acceleration factor Ea is the activation energy of the technology based on the failure rate k is the Boltzmann constant (8.6173 x 10-5 eV.K-1) TU is the temperature of the die when VU is used (K) TS is the temperature of the die under temperature stress (K) The final acceleration factor, AF, is the multiplication of the voltage acceleration factor and the temperature acceleration factor (Equation 4). Equation 4 A F = A FT  A FV AF is calculated using the temperature and voltage defined in the mission profile of the product. The AF value can then be used in Equation 5 to calculate the number of months of use equivalent to 1000 hours of reliable stress duration. DocID025992 Rev 1 17/28 28 Application information OA1MPA, OA2MPA, OA4MPA Equation 5 Months = A F  1000 h  12 months   24 h  365.25 days  To evaluate the op amp reliability, a follower stress condition is used where VCC is defined as a function of the maximum operating voltage and the absolute maximum rating (as recommended by JEDEC rules). The Vio drift (in µV) of the product after 1000 h of stress is tracked with parameters at different measurement conditions (see Equation 6). Equation 6 V CC = maxV op with V icm = V CC  2 The long term drift parameter (Vio), estimating the reliability performance of the product, is obtained using the ratio of the Vio (input offset voltage value) drift over the square root of the calculated number of months (Equation 7). Equation 7 V io drift V io = ----------------------------- months  where Vio drift is the measured drift value in the specified test conditions after 1000 h stress duration. 18/28 DocID025992 Rev 1 OA1MPA, OA2MPA, OA4MPA 4.6 Application information Initialization time The OA1MPA, OA2MPA, and OA4MPA series of devices use a proprietary trimming topology that is initiated at each device power-up and allows excellent Vio performance to be achieved. The initialization time is defined as the delay after power-up which guarantees operation within specified performances. During this period, the current consumption (ICC) and the input offset voltage (Vio) can be different to the typical ones. Figure 22. Initialization phase The initialization time is VCC and temperature dependent. Table 7 sums up the measurement results for different supply voltages and for temperatures varying from -40 °C to 125 °C. Table 7.
