noted. Typical values are at T
Note 1: All devices are 100% production tested at T
Note 2: All analog functions disabled and all digital inputs connected to supply or ground.
Note 3: High-speed/8 mode without CAN; V
Note 4: High-speed/1 mode with CAN; V
Note 5: Low speed, PMM1 mode without CAN; V
Note 6: CAN transmitting at 500kbps; 16-bit timer output switching at 500kHz; all active I/Os are loaded with a 20pF capacitor; all
Note 7: Guaranteed by design and characterization.
Note 8: This is not a static capacitance. It is the capacitance presented to the analog input when the T/H amplifier is in sample mode.
Note 9: The switched capacitor on the REFADC input can disturb the reference voltage. To reduce this disturbance, place a 0.1µF
Note 10: The digital design is fully static. However, the lower clock limit is set by a clock detect circuit. The MAXQ7670 switches to
