By default, the devices sample all 4 input channels
simultaneously. To delay the sampling instant on one or
more channels, program the appropriate byte in the
Sampling Instant Control register. The delay of the
actual sampling instant of each individual channel from
the default sampling instant (PHI_[7:0] = 0x00) is
adjustable between 32 to 819,121 XIN clock cycles,

Sampling Instant Control Register
Shutdown bit. Set SHDN high to place the device in shutdown mode. In shutdown mode, the internal
oscillator, fault circuitry, and internal bandgap reference are turned off. Set SHDN low for normal operation.
Reset bit. Set RST high to reset all registers to the default states except for the RST bit, and realign
sampling clocks and output data.
Enable 24-bit resolution bit for the MAX11040K. Set EN24BIT high to enable the 24-bit data output. Set
EN24BIT low to enable 19-bit data output with device address and channel address tags. Tables 5 and 6
specify the Data register for both states of this bit. Set to 0 for MAX11060.
Internal oscillator enable bit. When using the on-chip crystal oscillator as the clock source, set XTALEN high
to enable the crystal oscillator and provide a buffered version of the crystal clock at the CLKOUT output.
When using an external clock source, set XTALEN low to disable the internal crystal oscillator and three-
state the CLKOUT output. Connect the external clock source to the XIN input.
Overvoltage fault-protection disable bit. Set FAULTDIS high to disable the overvoltage fault-protection
circuits. For FAULTDIS = 0, the absolute maximum input range is ±6V. Analog inputs beyond the fault-
detection threshold range trip the fault-protection circuits. The output remains clipped for a fault-recovery
time (typically < 1.57ms) after the inputs return within the fault-detection threshold range. For FAULTDIS =
1, the absolute maximum input range is only ±3.5V, but there is no fault-recovery delay. See the
Overvoltage Fault Detection and Recovery (FAULT) section.
PDBUF = 1 disables the internal reference buffer. Use this mode when an external reference is used;
otherwise, PDBUF should be set to 0 to enable the internal reference buffer.
Must set to 0.
Channel 0 sample instant adjust. PHI0 delays sampling instant on channel 0 by 32 XIN clock cycles per
LSB, up to 8192 cycles total (1.3μs resolution; 333μs range at XIN of 24.576MHz).
Channel 1 sample instant adjust. PHI1 delays sampling instant on channel 1 by 32 XIN clock cycles per
LSB, up to 8192 cycles total (1.3μs resolution; 333μs range at XIN of 24.576MHz).
Channel 2 sample instant adjust. PHI2 delays sampling instant on channel 2 by 32 XIN clock cycles per
LSB, up to 8192 cycles total (1.3μs resolution; 333μs range at XIN of 24.576MHz).
Channel 3 sample instant adjust. PHI3 delays sampling instant on channel 3 by 32 XIN clock cycles per
LSB, up to 8192 cycles total (1.3μs resolution; 333μs range at XIN of 24.576MHz).

The Configuration register contains 5 bits that control the
functionality of the devices. The default state is 0x00.
The data length of the Configuration register is 8 bits
per cascaded device (see Table 4).
