ELECTRICAL CHARACTERISTICS (continued)
(VDDF = VDD = 4.5V to 5.5V, VSSF = VSS = 0V, fCLK = 4.0MHz, TA = TMIN to TMAX. Typical values are at VDDF = VDD = 5.0V, VSSF = VSS = 0V,
TA = +25°C, unless otherwise noted.) (Note 1)
Note 1:
Current into a pin is defined as positive. Current out of a pin is defined as negative. All voltages are referenced to VSS.
Note 2:
All modules are off, except internal reference, oscillator, and power-on reset (POR) and CKSEL bit is set to zero.
Note 3:
The CPU and ADC are not on at the same time. The ADC and CPU currents are not additive.
Note 4:
IDACn does not include output buffer currents (IOPLGn or IOPSMn).
Note 5:
For gains above 240, an additional digital gain can be provided by the CPU.
Note 6:
The PWM input data is the 12-bit left-justified data in the 16-bit input field.
Note 7:
PWM gain error measured as:
Note 8:
The internal reference voltage has a nominal value of 5V (4
VBG) even when VDD is greater or less than 5VDC.
Note 9:
Input-referred offset error is the ADC offset error divided by the PGA gain.
Note 10: When the CKIO is configured in output mode to observe the internal oscillator signal, the total current is above the
specified limits.
Note 11: fCLK must be within 5% of 4MHz.
Note 12: Allow a minimum elapsed time of 4.2ms when executing a FLASH erase command, before sending any other command.
Allow a minimum elapsed time of 80s between FLASH write commands.
Note 13: FLASH programming current is guaranteed by design.
