50.1 Electrical Parameters Usage

The sections that follow provide the limiting values for device electrical parameters.

• Unless otherwise noted, these values are valid over the junction temperature range T_J= [-40°C + 100°C].
• Parameters annotated as “Simulation data” are not production-tested. Their limiting values come from simulations run in corner case conditions and were verified by electrical characterization over a limited number of samples.
• These limits may be affected by the board on which the device is mounted. In particular, noisy supply and ground conditions must be avoided and care must be taken to provide:
  • a PCB with a low impedance ground plane (a single unbroken ground plane is strongly recommended)
  • low impedance decoupling of the device power supply inputs. A 10 nF to 220 nF Ceramic X7R (or X5R) capacitor placed very close to each power supply input is a minimum requirement. See specific recommendations regarding analog pins or functions in the corresponding sections. To reduce any potential electromagnetic compatibility (EMC) related issues, it is good practice to double this decoupling capacitor whenever possible with a high frequency one, for example, one 100 pF (C0G or NP0) per power supply input.
  • low impedance power supply decoupling of external components. This recommendation aims at avoiding large current spikes flowing into the PCB ground and power planes.
• In addition, although the device is specified with wide operating supply ranges on most of its supply inputs, large and fast supply variations may lead to unpredictable device behavior including, but not limited to, out-of-specification operation. It is therefore mandatory to keep the power supply variations within the limits given in Table 50-1 during device operation.
