MAX6675 Cold-Junction-Compensated K-Thermocouple- to-Digital Converter (0°C to +1024°C)
Electrical Characteristics (continued)
(VCC = +3.0V to +5.5V, TA = -20°C to +85°C, unless otherwise noted. Typical values specified at +25°C.) (Note 1)
PARAMETER SYMBOL CONDITIONS MIN TYP MAX UNITS
Output High Voltage VOH ISOURCE = 1.6mA VCC - 0.4 V Output Low Voltage VOL ISINK = 1.6mA 0.4 V
TIMING
Serial Clock Frequency fSCL 4.3 MHz SCK Pulse High Width tCH 100 ns SCK Pulse Low Width tCL 100 ns CSB Fall to SCK Rise tCSS CL = 10pF 100 ns CSB Fall to Output Enable tDV CL = 10pF 100 ns CSB Rise to Output Disable tTR CL = 10pF 100 ns SCK Fall to Output Data Valid tDO CL = 10pF 100 ns
Note 1:
All specifications are 100% tested at TA = +25°C. Specification limits over temperature (TA = TMIN to TMAX) are guaranteed by design and characterization, not production tested.
Note 2:
Guaranteed by design. Not production tested.
Typical Operating Characteristics
(VCC = +3.3V, TA = +25°C, unless otherwise noted.)
