Resistor Terminal Input Voltage Range (Terminals A, B and W) VA,VW,VB Vss — VDD V Note 5, Note 6 Maximum current through A, W or B (Note 6) IW — — 2.5 mA Terminal A IAW, W = Full Scale (FS) — — 2.5 mA Terminal B IBW, W = Zero Scale (ZS) — — 2.5 mA Terminal W IAW (W = FS) or IBW (W = ZS) Maximum RAB current (IAB) (Note 6) IAB —— 1.38 mA VB = 0V, VA = 5.5V, RAB(MIN) = 4000Ω — — 0.688 mA VB = 0V, VA = 5.5V, RAB(MIN) = 8000Ω — — 0.138 mA VB = 0V, VA = 5.5V, RAB(MIN) = 40000Ω — — 0.069 mA VB = 0V, VA = 5.5V, RAB(MIN) = 80000Ω Leakage current into A, W or B IWL —100 — nA MCP44X1 PxA = PxW = PxB = VSS —100 — nA MCP44X2 PxB = PxW = VSS — 100 — nA Terminals Disconnected (R0A = R0W = R0B = 0; R1A = R1W = R1B = 0; R2A = R2W = R2B = 0; R3A = R3W = R3B = 0) AC/DC CHARACTERISTICS (CONTINUED) DC Characteristics 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, 5 kΩ, 10 kΩ, 50 kΩ, 100 kΩ devices. Typical specifications represent values for VDD = 5.5V, TA = +25°C. Parameters Sym Min Typ Max Units Conditions Note 1: Resistance is defined as the resistance between terminal A to terminal B. 2: INL and DNL are measured at VW with VA = VDD and VB = VSS. 3: MCP44X1 only. 4: MCP44X2 only, includes VWZSE and VWFSE. 5: Resistor terminals A, W and B’s polarity with respect to each other is not restricted. 6: This specification by design. 7: Non-linearity is affected by wiper resistance (RW), which changes significantly over voltage and temperature. 8: The MCP44X1 is externally connected to match the configurations of the MCP44X2, and then tested. 9: POR/BOR is not rate dependent. 10: Supply current is independent of current through the resistor network. 11: When HVC/A0 = VIHH, the IDD current is less due to current into the HVC/A0 pin.
