Serial Data Output. Data changes state on SCLK’s falling edge in SPI/QSPI/MICROWIRE
mode and on SCLK’s rising edge in DSP mode (MAX1168 only). DOUT is high impedance
when CS is high.
Serial Clock Input. SCLK drives the conversion process in external clock mode and clocks
data out.
Serial Data Input. Use DIN to communicate with the command/configuration/control
register. In SPI/QSPI/MICROWIRE mode, the rising edge of SCLK clocks in data at DIN. In
DSP mode, the falling edge of SCLK clocks in data at DIN.
End-of-Conversion Output. In internal clock mode, a logic low at EOC signals the end of a
conversion with the result available at DOUT. In external clock mode, EOC remains high.

Analog Ground. Connect to pin 18 (MAX1168) or pin 12 (MAX1167).
Primary Analog Ground (Star Ground). Power return for AV
Analog Supply Voltage. Bypass to AGND with a 0.1µF capacitor.
Active-Low Chip-Select Input. Forcing CS high places the MAX1167/MAX1168 in shutdown
with a typical supply current of 0.6µA. In SPI/QSPI/MICROWIRE mode, a high-to-low
transition on CS activates normal operating mode. In DSP mode, after the initial CS
transition from high to low, CS can remain low for the entire conversion process (see the
Operating Modes section).
Digital Ground
Digital Supply Voltage. Bypass to DGND with a 0.1µF capacitor.
DSP Frame-Sync Receive Input. A frame-sync pulse received at DSPR initiates a
conversion. Connect to logic high when using SPI/QSPI/MICROWIRE mode.
Data-Bit Transfer-Select Input. Logic low on DSEL places the device in 8-bit-wide data-
transfer mode. Logic high places the device in 16-bit-wide data-transfer mode. Do not
leave DSEL unconnected.
