Midscale Voltage Bypass. For the MAX1319, connect a 2.2µF and a 0.1µF capacitor from MSV to
AGND. For the MAX1323/MAX1327, connect MSV directly to AGND.
Clock-Mode Select Input. Use INTCLK/EXTCLK to select the internal or external conversion clock.

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.
