Data Byte (Read Cycle)
A read cycle must be initiated to obtain conversion
results. Read cycles begin with the bus master issuing
a START condition followed by seven address bits and
a read bit (R/W = 1). If the address byte is successfully
received, the MAX11612–MAX11617 (slave) issues an
acknowledge. The master then reads from the slave.
The result is transmitted in two bytes; first four bits of
the first byte are high, then MSB through LSB are con-
secutively clocked out. After the master has received
the byte(s), it can issue an acknowledge if it wants to
continue reading or a not-acknowledge if it no longer
wishes to read. If the MAX11612–MAX11617 receive a
not-acknowledge, they release SDA, allowing the master
to generate a STOP or a repeated START condition. See
the
Clock Modes and Scan Mode sections for detailed
information on how data is obtained and converted.
Clock Modes
The clock mode determines the conversion clock and
the data acquisition and conversion time. The clock
mode also affects the scan mode. The state of the set-
up byte’s CLK bit determines the clock mode (Table 1).
At power-up, the MAX11612–MAX11617 are defaulted
to internal clock mode (CLK = 0).
Internal Clock
When configured for internal clock mode (CLK = 0), the
MAX11612–MAX11617 use their internal oscillator as the
conversion clock. In internal clock mode, the MAX11612–
MAX11617 begin tracking the analog input after a valid
address on the eighth rising edge of the clock. On the
falling edge of the ninth clock, the analog signal is acquired
and the conversion begins. While converting the analog
input signal, the MAX11612–MAX11617 holds SCL low
(clock stretching). After the conversion completes, the
results are stored in internal memory. If the scan mode is set
for multiple conversions, they all happen in succession with
each additional result stored in memory. The MAX11612/
MAX11613 contain four 12-bit blocks of memory, the
MAX11614/MAX11615 contain eight 12-bit blocks of memo-
ry, and the MAX11616/MAX11617 contain twelve 12-bit
blocks of memory. Once all conversions are complete, the
MAX11612–MAX11617 release SCL, allowing it to be pulled
high. The master can now clock the results out of the mem-
ory in the same order the scan conversion has been done
at a clock rate of up to 1.7MHz. SCL is stretched for a maxi-
mum of 8.3s per channel (see Figure 10).
The device memory contains all of the conversion
results when the MAX11612–MAX11617 release SCL.

1For the MAX11612/MAX11613, CS3 and CS2 are internally set to 0. For the MAX11614/MAX11615, CS3 is internally set to 0.
2When SEL1 = 1, a differential read between AIN2 and AIN3/REF (MAX11612/MAX11613) or AIN10 and AIN11/REF
(MAX11616/MAX11617) returns the difference between GND and AIN2 or AIN10, respectively. For example, a differential read of 1011
returns the negative difference between AIN10 and GND. This does not apply to the MAX11614/MAX11615 as each provides separate
pins for AIN7 and REF. In differential scanning, the address increments by 2 until the limit set by CS3–CS1 has been reached.
