Specifications of MAX1168EVKIT

• Interface Type: QSPI, Serial (SPI, Microwire)

The MAX1168 EV kit board provides a proven layout for
evaluating the MAX1168 8-channel, 16-bit ADC and can
be obtained separately without the 68HC16MODULE-
DIP µC module for use with an existing µC. The
MAX1168 EV kit contains two different types of buffers.
U2 is a logic buffer to limit the load capacitance that is
seen by the DOUT line of the MAX1168. U3–U10 are 16-
bit accurate analog buffers connected in the unity-gain
configuration. U1 is powered from V
powered from V
module (J1-7, J1-8). A terminal block (TB0) has also
been provided on the MAX1168 EV kit board for evaluat-
ing external reference mode. Refer to the
MAX1167/MAX1168 or MAX1067/ MAX1068 data sheets
to ensure all interface timing specifications are met.
The MAX1168 and MAX1168 EV kit board support DSP
and 16-bit-wide data-transfer mode. Jumpers JU1 and
JU2 can be configured for these modes; however, the
supplied EV kit Windows-compatible software does not
support these two modes. Please refer to the
MAX1167/MAX1168 or MAX1067/MAX1068 data sheets
for more information.

Pressing the Read ADC button performs the conversion(s) specified by the control byte and reads back
the result(s).
Checking the AutoRead checkbox performs the conversion(s) specified by the control byte and reads
back the result(s) every 500ms. A blinking asterisk indicates AutoRead is active.
