Rheostat Differential Non-linearity MCP45X1 (Note 4, Note 8) MCP4XX2 devices only (Note 4) R-DNL -0.5 ±0.25 +0.5 LSb 5 k 8-bit 5.5V, IW = 900 µA -1.0 +0.5 +1.0 LSb 3.0V, IW = 480 µA (Note 7) -0.375 ±0.25 +0.375 LSb 7-bit 5.5V, IW = 900 µA -0.75 +0.5 +0.75 LSb 3.0V, IW = 480 µA (Note 7) -0.5 ±0.25 +0.5 LSb 10 k 8-bit 5.5V, IW = 450 µA -1.0 +0.25 +1.0 LSb 3.0V, IW = 240 µA (Note 7) -0.375 ±0.25 +0.375 LSb 7-bit 5.5V, IW = 450 µA -0.75 +0.5 +0.75 LSb 3.0V, IW = 240 µA (Note 7) -0.5 ±0.25 +0.5 LSb 50 k 8-bit 5.5V, IW = 90 µA -0.5 ±0.25 +0.5 LSb 3.0V, IW = 48 µA (Note 7) -0.375 ±0.25 +0.375 LSb 7-bit 5.5V, IW = 90 µA -0.375 ±0.25 +0.375 LSb 3.0V, IW = 48 µA (Note 7) -0.5 ±0.25 +0.5 LSb 100 k 8-bit 5.5V, IW = 45 µA -0.5 ±0.25 +0.5 LSb 3.0V, IW = 24 µA (Note 7) -0.375 ±0.25 +0.375 LSb 7-bit 5.5V, IW = 45 µA -0.375 ±0.25 +0.375 LSb 3.0V, IW = 24 µA (Note 7) Capacitance (PA)CAW — 75 — pF f =1 MHz, Code = Full-Scale Capacitance (Pw)CW — 120 — pF f =1 MHz, Code = Full-Scale Capacitance (PB)CBW — 75 — pF f =1 MHz, Code = Full-Scale AC/DC CHARACTERISTICS (CONTINUED) DC Characteristics Standard Operating Conditions (unless otherwise specified) Operating Temperature –40°C T A +125°C (extended) All parameters apply across the specified operating ranges unless noted. VDD = +2.7V to 5.5V, 5 k, 10 k, 50 k, 100 k 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: MCP4XX1 only. 4: MCP4XX2 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 overvoltage and temperature. 8: The MCP4XX1 is externally connected to match the configurations of the MCP45X2 and MCP46X2, 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.
