DS22011B-page 5 MCP3905A/05L/06A TIMING CHARACTERISTICS Electrical Specifications: Unless otherwise indicated, all parameters apply at AVDD = DVDD = 4.5V – 5.5V, AGND, DGND = 0V, MCLK = 3.58 MHz; TA = -40°C to +85°C. Parameter Sym Min Typ Max Units Comment Frequency Output FOUT0 and FOUT1 Pulse Width (Logic Low) for MCP3905A, MCP3906A devices tFW — 275 — ms 984376 MCLK periods (Note 1) HFOUT Pulse Width for MCP3905A, MCP3906A devices tHW — 90 — ms 322160 MCLK periods (Note 2) FOUT0 and FOUT1 Pulse Width (Logic Low) for MCP3905L device tFW — 130 — ms 465344 MCLK periods (Note 1) HFOUT Pulse Width for MCP3905L device tHW — 65 — ms 232672 MCLK periods (Note 2) FOUT0 and FOUT1 Pulse Period tFP Refer to Equation 4-1 s HFOUT Pulse Period tHP Refer to Equation 4-2 s FOUT0 to FOUT1 Falling-Edge Time tFS2 — 0.5 tFP — FOUT0 to FOUT1 Min Separation tFS — 4/MCLK — FOUT0 and FOUT1 Output High Voltage VOH 4.5 —— VIOH = 10 mA, DVDD = 5.0V FOUT0 and FOUT1 Output Low Voltage VOL —— 0.5 V IOL = 10 mA, DVDD = 5.0V HFOUT Output High Voltage VOH 4.0 —— VIOH = 5 mA, DVDD = 5.0V HFOUT Output Low Voltage VOL —— 0.5 V IOL = 5 mA, DVDD = 5.0V High-Level Input Voltage (All Digital Input Pins) VIH 2.4 —— VDVDD = 5.0V Low Level Input Voltage (All Digital Input Pins) VIL —— 0.85 V DVDD = 5.0V Input Leakage Current —— ±3 µA VIN = 0, VIN = DVDD Pin Capacitance —— 10 pF Note 3 Note 1: If output pulse period (tFP) falls below 984376*2 MCLK periods for MCP3905A/6A and 465344*2 MCLK periods for MCP3905L, then tFW = 1/2 tFP. 2: If output pulse period (tHP) falls below 322160*2 MCLK periods for MCP3905A/6A and 232672*2 MCLK periods for MCP3905L, then tHW = 1/2 tHP. When F2, F1,F0 = 011, tHW is fixed to 18 µs (64 MCLK periods). 3: Specified by characterization, not production tested. |
