Clock-Mode Select Input. Use INTCLK/EXTCLK to select the internal
or external conversion clock. Connect INTCLK/EXTCLK to AV
select the internal clock. Connect INTCLK/EXTCLK to AGND to use
an external clock connected to CLK.
Midscale Reference Bypass or Input. REF
an internally generated reference voltage. For the MAX1316/
MAX1317/MAX1318, connect a 0.1µF capacitor from REF
AGND. For the MAX1320/MAX1321/MAX1322/MAX1324/
MAX1325/MAX1326, connect REF
with a 0.1µF capacitor from REF
ADC Reference Bypass or Input. REF is the bypass point for an
internally generated reference voltage. Bypass REF with a 0.01µF
capacitor to AGND. REF can be driven externally by a precision
external voltage reference.
Positive Reference Bypass. REF+ is the bypass point for an
internally generated reference voltage. Bypass REF+ with a 0.1µF
capacitor to AGND. Also bypass REF+ to REF- with a 2.2µF and a
0.1µF capacitor.
Reference Common Bypass. COM is the bypass point for an
internally generated reference voltage. Bypass COM to AGND with
a 2.2µF and a 0.1µF capacitor.
Negative Reference Bypass. REF- is the bypass point for an
internally generated reference voltage. Bypass REF- with a 0.1µF
capacitor to AGND. Also bypass REF- to REF+ with a 2.2µF and a
0.1µF capacitor.
Digital I/O Bit 0 of 14-Bit Parallel Data Bus. High impedance when
RD = 1 or CS = 1.
Digital I/O Bit 1 of 14-Bit Parallel Data Bus. High impedance when
RD = 1 or CS = 1.
Digital I/O Bit 2 of 14-Bit Parallel Data Bus. High impedance when
RD = 1 or CS = 1.
