DS21950E-page 5 MCP3550/1/3 Voltage Output Low (SDO/RDY)VOL —— 0.4 V VOH = -1 mA, VDD = 5.0V Input leakage Current (CS, SCK) ILI -1 — 1 µA Internal Pin Capacitance (CS, SCK, SDO/RDY) CINT —5 — pF Note 1 DC CHARACTERISTICS (CONTINUED) Electrical Specifications: Unless otherwise indicated, all parameters apply at -40°C ≤ TA ≤ +85°C, VDD = 2.7V or 5.0V. VREF = 2.5V. VIN+ = VIN- = VCM = VREF/2. All ppm units use 2*VREF as full scale range. Unless otherwise noted, specification applies to entire MCP3550/1/3 family. Parameters Sym Min Typ Max Units Conditions Note 1: This parameter is established by characterization and not 100% tested. 2: INL is the difference between the endpoints line and the measured code at the center of the quantization band. 3: This current is due to the leakage current and the current due to the offset voltage between VIN+ and VIN-. 4: Input impedance is inversely proportional to clock frequency; typical values are for the MCP3550/1 device. VREF =5V. 5: Characterized by design, but not tested. 6: Rejection performance depends on internal oscillator accuracy; see Section 4.0 “Device Overview” for more informa- tion on oscillator and digital filter design. MCP3550/1 device rejection specifications characterized from 49 to 61 Hz. TEMPERATURE CHARACTERISTICS Electrical Specifications: Unless otherwise indicated Parameters Sym Min Typ Max Units Conditions Temperature Ranges Specified Temperature Range TA -40 — +85 °C Operating Temperature Range TA -40 — +125 °C Thermal Package Resistances Thermal Resistance, 8L-MSOP θJA —211 — °C/W Thermal Resistance, 8L-SOIC θJA — 149.5 — °C/W SERIAL TIMINGS Electrical Specifications: Unless otherwise indicated, all parameters apply at -40°C ≤ TA ≤ +85°C, VDD = 3.3V or 5.0V, SDO load = 50 pF.
