ADC Conversion Sequence
Each time a conversion begins, all channels are con-
verted, and the results of the measurements are avail-
able after the end of conversion. A BUSY status bit in
the Status Byte shows that the device is actually per-
forming a new conversion; however, even if the ADC is
busy, the results of the previous conversion are always
available. The conversion sequence for the MAX6655
(MAX6656) is External Diode 1, External Diode 2,
Internal Diode, V IN3 , V IN2 (V CC ), V IN1 , V CC (V IN2 ).
The ADC always converts at maximum speed, but the
time between a sequence of conversions is adjustable.
The Conversion Rate Control Byte (Table 1) shows the
possible delays between conversions. Disabling voltage
or temperature measurements with the Configuration
Byte makes the ADC complete the conversion
sequence faster.
Low-Power Standby Mode
Standby mode disables the ADC and reduces the sup-
ply current drain to 3μA (typ). Enter standby mode by
forcing STBY low or through the RUN/STOP bit in the
Configuration Byte register. Hardware and software
standby modes behave identically; all data is retained
in memory, and the SMBus interface is alive and listen-
ing for reads and writes. Standby mode is not a shut-
down mode. Activity on the SMBus draws extra supply
current (see Typical Operating Characteristics ).
Enter hardware standby mode by forcing STBY low. In
a notebook computer, this line may be connected to
the system SUSTAT# suspend-state signal. The STBY
low state overrides any software conversion command.
If a hardware or software standby command is
received while a conversion is in progress, the conver-
sion cycle is truncated, and the data from that conver-
sion is not latched into the Temperature Reading
register. The previous data is not changed and remains
available.
Supply current during the 125ms conversion is typically
550μA. Between conversions, the instantaneous supply
current is about 25μA, due to the current consumed by
the conversion-rate timer. With very low supply voltages
(under the POR threshold), the supply current is higher
due to the address input bias currents.
