The devices’ parameters are fully specified for 2.7 V and 5 V power supplies. Additionally, the main specifications are guaranteed in extended temperature ranges from -40° C to +125° C. 4.2 Input common-mode range The LMX321, LMX358, and LMX324 have an input common-mode range that includes ground. The input common-mode range is extended from VCC- - 0.2 V to VCC+ - 1 V, with no output phase reversal. 4.3 Rail-to-rail output The operational amplifiers’ output levels can go close to the rails: to a maximum of 180 mV above and below the rail when connected to a 10 kΩ resistive load to VCC/2. 4.4 Input offset voltage drift over temperature The maximum input voltage drift over the temperature variation is defined in Equation 1. Equation 1 ΔVio ( T ) – Vio ( 25° C ) ------------ = max Vio ---------------------------------------------------ΔT T – 25° C for Tmin < T < Tmax. 4.5 PCB layouts For correct operation, it is advised to add 10 nF decoupling capacitors as close as possible to the power supply pins. 4.6 Macromodel Accurate macromodels of the LMX321, LMX358, and LMX324 are available on STMicroelectronics’ web site at www.st.com. These models are a trade-off between accuracy and complexity (that is, time simulation) of the LMX321, LMX358, and LMX324 operational amplifiers. They emulate the nominal performances of a typical device within the specified operating conditions mentioned in the datasheet. They also help to validate a design approach and to select the right operational amplifier, but they do not replace on-board measurements.
