10 / 48 page 10 Am79C02/03/031(A) Data Sheet ELECTRICAL CHARACTERISTICS over operating range unless otherwise noted Typical values are for TA = 25°C and nominal supply voltages. Minimum and maximum specifications are over the temperature and supply voltage ranges shown in Operating Ranges. Notes: 1. When the DSLAC device is in the Inactive mode, the analog output presents a 0 V output level through a ~3 k Ω resistor. 2. The C1–C5 outputs are resistive for less than a 1 V drop. Total current must not exceed absolute maximum ratings. 3. If there is an external DC path from VOUT to VIN with a gain of GDC and the AISN has a gain of hAISN, then the output offset is multiplied by 1/[1 – (hAISN • GDC)]. 4. Power Dissipation in the Inactive mode is measured with all digital inputs at VIH = VCC and VIL = VSS and with no load connected to VOUT1 or VOUT2.
