6 / 102 page  MCP454X/456X/464X/466X DS22107B-page 6 2008-2013 Microchip Technology Inc. Maximum current through Terminal (A, W or B) Note 6 IT — — 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 or IBW, W = FS or ZS —— 1.38 mA Terminal A and Terminal B IAB, VB = 0V, VA = 5.5V, RAB(MIN) = 4000 —— 0.688 mA IAB, VB = 0V, VA = 5.5V, RAB(MIN) = 8000 —— 0.138 mA IAB, VB = 0V, VA = 5.5V, RAB(MIN) = 40000 —— 0.069 mA IAB, VB = 0V, VA = 5.5V, RAB(MIN) = 80000 Leakage current into A, W or B IWL —100 — nA MCP4XX1 PxA = PxW = PxB = VSS —100 — nA MCP4XX2 PxB = PxW = VSS — 100 — nA Terminals Disconnected (R1HW = R0HW = 0) 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. See IPU specification. |
