sists. Note that the ALERT interrupt latch is not auto-
matically cleared when the status flag bit is cleared.
When auto-converting, if the T
HIGH
and T
LOW
limits are
close together, its possible for both high-temp and low-
temp status bits to be set, depending on the amount of
time between status read operations (especially when
converting at the fastest rate). In these circumstances,
its best not to rely on the status bits to indicate rever-
sals in long-term temperature changes and instead use
a current temperature reading to establish the trend
direction.
Conversion Rate Byte
The conversion rate register (Table 7) programs the time
interval between conversions in free-running auto-convert
mode. This variable rate control reduces the supply cur-
rent in portable-equipment applications. The conversion
rate bytes POR state is 02h (0.25Hz). The MAX1617A
looks only at the 3 LSB bits of this register, so the upper 5
bits are dont care bits, which should be set to zero. The
conversion rate tolerance is ?5% at any rate setting.
Valid A/D conversion results for both channels are avail-
able one total conversion time (125ms nominal, 156ms
maximum) after initiating a conversion, whether conver-
sion is initiated via the RUN/STOP bit, hardware STBY
pin, one-shot command, or initial power-up. Changing the
conversion rate can also affect the delay until new results
are available (Table 8).
Manufacturer and Device ID Codes
Two ROM registers provide manufacturer and device ID
codes (Table 4). Reading the manufacturer ID returns
4Dh, which is the ASCII code M (for Maxim). Reading
the device ID returns 01h, indicating a MAX1617A
device. If READ WORD 16-bit SMBus protocol is
employed (rather than the 8-bit READ BYTE), the least
significant byte contains the data and the most signifi-
cant byte contains 00h in both cases.
Slave Addresses
The MAX1617A appears to the SMBus as one device
having a common address for both ADC channels. The
device address can be set to one of nine different val-
ues by pin-strapping ADD0 and ADD1 so that more
than one MAX1617A can reside on the same bus with-
out address conflicts (Table 9).
