DS22197A-page 5 MCP631/2/3/5 1.3 Timing Diagram FIGURE 1-1: Timing Diagram. 1.4 Test Circuits The circuit used for most DC and AC tests is shown in Figure 1-2. It independently sets VCM and VOUT; see Equation 1-1. The circuit’s common mode voltage is (VP +VM)/2, not VCM. VOST includes VOS plus the effects of temperature, CMRR, PSRR and AOL. EQUATION 1-1: FIGURE 1-2: AC and DC Test Circuit for Most Specifications. TABLE 1-4: TEMPERATURE SPECIFICATIONS Electrical Characteristics: Unless otherwise indicated, all limits are specified for: VDD = +2.5V to +5.5V, VSS = GND. Parameters Sym Min Typ Max Units Conditions Temperature Ranges Specified Temperature Range TA -40 — +125 °C Operating Temperature Range TA -40 — +125 °C (Note 1) Storage Temperature Range TA -65 — +150 °C Thermal Package Resistances Thermal Resistance, 8L-3x3 DFN θJA —60 — °C/W (Note 2) Thermal Resistance, 8L-SOIC θJA — 149.5 — °C/W Thermal Resistance, 10L-3x3 DFN θJA —57 — °C/W (Note 2) Thermal Resistance, 10L-MSOP θJA — 202 — °C/W Note 1: Operation must not cause TJ to exceed Maximum Junction Temperature specification (+150°C). 2: Measured on a standard JC51-7, four layer printed circuit board with ground plane and vias.
