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 Resistor Ladder Resistance RL 100 140 180 k VRnB:VRnA = 10, VREF = VDD(6) 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 Temperature Coefficient (see B.19 “VOUT Temperature Coefficient”) VOUT/T — 15 — ppm/°C Code = Midscale (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. 2: This parameter is ensured by characterization. 6: Resistance is defined as the resistance between the VREF pin (mode VRnB:VRnA = 10) to VSS pin. For octal-channel devices (MCP48FXBX8), this is the effective resistance of each resistor ladder. The resistance measurement is one of the two resistor ladders measured in parallel. 11: Variation of one output voltage to mean output voltage. |
