MAX1134/MAX1135
The user-programmable outputs are set to zero during
power-on reset or when RST goes low. During hardware
or software shutdown, P0, P1, and P2 are unchanged
and remain low impedance.
Starting a Conversion
Start a conversion by clocking a control byte into the
device’s internal shift register. With CS low, each rising
edge on SCLK clocks a bit from DIN into the
MAX1134/MAX1135s’ internal shift register. After CS
goes low or after a conversion or calibration completes,
the first arriving logic 1 is defined as the start bit of the
control byte. Until this first start bit arrives, any number of
logic 0 bits can be clocked into DIN with no effect. If at
any time during acquisition or conversion CS is brought
high and then low again, the part is placed into a state
where it can recognize a new start bit. If a new start bit
occurs before the current conversion is complete, the
conversion is aborted and a new acquisition is initiated.
Internal and External Clock Modes
The MAX1134/MAX1135 use either the external serial
clock or the internal clock to perform the successive-
approximation conversion. In both clock modes, the
external clock shifts data in and out of the
MAX1134/MAX1135. Bit 5 (INT/EXT) of the control byte
programs the clock mode.
External Clock
In external clock mode, the external clock not only
shifts data in and out, but also drives the ADC conver-
sion steps.
In short acquisition mode, SSTRB pulses high for one
clock period after the seventh falling edge of SCLK fol-
lowing the start bit. The MSB of the conversion is avail-
able at DOUT on the eighth falling edge of SCLK
(Figure 2).
