DC CHARACTERISTICS (CONTINUED) DC Characteristics Standard Operating Conditions (unless otherwise specified): Operating Temperature: -40°C TA +125°C (Extended) Unless otherwise noted, all parameters apply across these specified operating ranges: VDD = +2.7V to 5.5V, VREF = +2.048V to VDD, VSS = 0V Gx = ‘0’, RL = 5 k from VOUT to VSS, CL = 100 pF Typical specifications represent values for VDD = 5.5V, TA = +25°C. Parameters Sym. Min. Typ. Max. Units Conditions Resistor Ladder Resistance RL 100 140 180 k 1.8V VDD 5.5V VREF 1.0V (7) Resolution (# of Resistors and # of Taps) (see B.1 “Resolution” ) N 256 Taps 8-bit No Missing Codes 1024 Taps 10-bit No Missing Codes 4096 Taps 12-bit No Missing Codes Nominal VOUT Match (11) |VOUT - VOUTMEAN| /VOUTMEAN — 0.5 1.0 % 2.7V VDD 5.5V (2) — — 1.2 % 1.8V (2) VOUT Tempco (see B.19 “VOUT Temperature Coefficient” ) VOUT/T — 15 — ppm/°C Code = Mid-scale (7Fh, 1FFh or 7FFh) VREF pin Input Voltage Range VREF VSS —VDD V1.8V VDD 5.5V (1) Note 1 This parameter is ensured by design. Note 2 This parameter is ensured by characterization. Note 7 Resistance is defined as the resistance between the VREF pin (mode VRxB:VRxA = ‘10’) to VSS pin. For dual-channel devices (MCP48FEBX2), this is the effective resistance of the each resistor ladder. The resistance measurement is of the two resistor ladders measured in parallel. Note 11 Variation of one output voltage to mean output voltage. |
