Table 8: DC Electrical Specifications

Unless otherwise stated, all power supplies = 2.5V, no load on any output, and ambient temperature range TA = 0°C to 70°C. Parameters denoted with an asterisk ( * ) represent nominal characteri-

zation data and are not currently production tested to any specific limits. MIN and MAX characterization data are ± 3σ f rom typical. Negative currents indicate current flows out of the device.
