7 / 112 page  2020 Microchip Technology Inc. DS20006362A-page 7 MCP48FXBX4/8 DC CHARACTERISTICS (CONTINUED) Standard Operating Conditions (unless otherwise specified): Operating Temperature: -40°C TA +125°C (Extended). All parameters apply across the specified operating ranges unless noted. VDD = +2.7V to 5.5V, VREF = +2.048V to VDD, VSS = 0V, Gx = 0, RL = 5 k from VOUT to GND, CL = 100 pF. Typical specifications represent values for VDD = 5.5V, TA = +25°C. Parameters Sym. Min. Typ. Max. Units Conditions Supply Current IDD — — 1.0 mA Quad 1 MHz(1) Serial interface active (not High-Voltage Command), VRnB:VRnA = All Modes(4), VOUT is unloaded, VDD = 5.5V, Volatile DAC Register = Midscale —— 1.7 mA 10 MHz(1) —— 2.6 mA 20 MHz —— 1.6 mA Octal 1 MHz(1) —— 2.3 mA 10 MHz(1) —— 3.2 mA 20 MHz — — 0.85 mA Quad Serial interface inactive(1) (not High-Voltage Command), VRnB:VRnA = All Modes, SCK = SDI = VSS, VOUT is unloaded, Volatile DAC Register = Midscale —— 1.6 mA Octal — — 2.2 mA Quad EE write current, VREF = VDD = 5.5V (after write, serial interface is inactive), write 0x7FF to nonvolatile DAC0 (address 10h), VOUT pins are unloaded —— 2.7 mA Octal — 560 700 µA Quad HVC = 12.5V (High-Voltage Command), serial interface inactive, VREF = VDD = 5.5V, LAT/HVC = VIHH, DAC Registers = Midscale, VOUT pins are unloaded — 1100 1300 µA Octal Power-Down Current IDDP — 0.68 3.8 µA PDnB:PDnA = 01(5), VOUT not connected Note 1: This parameter is ensured by characterization. 4: Supply current is independent of current through the resistor ladder in mode VRnB:VRnA = 10. 5: The PDnB:PDnA = 00, 10 and 11 configurations should have the same current. |
