Table 8: DC Electrical Specifications
Unless otherwise stated, all power supplies = 3.3V ± 10%, no load on any output, and ambient temperature range TA = 0°C to 70°C. Parameters denoted with an asterisk ( * ) represent nominal
characterization data and are not currently production tested to any specific limits. MIN and MAX characterization data are ± 3σ from typical. Negative currents indicate current flows out of the device.
