Shown here is the internal block schematic of the sixteen or twenty-four channel device. Even with the increased the number of channels, the package size remains at five-by-five millimeters for the 24 channel device and even a smaller four-by-four millimeter package for the 16 channel unit. Most of the other performance specifications are similar to the current generation of devices in terms of temperature range and supply voltage. The main differences are a higher number of channels, higher sensitivity, more PWM controllers, and the Auto-Tune function.
