G2, G1, G0:
(Default = 0, 0, 0) Gain-Selection Bits. See
Table 11 for PGA gain settings.
B
/U:
(Default = 0) Bipolar-/Unipolar-Mode Selection:
Set
B
/U = 0 to select bipolar mode. Set
B
/U = 1 to
select unipolar mode.
BUF:
(Default = 0) Buffer-Enable Bit. For unbuffered
mode, disable the internal buffer of the MAX1415/
MAX1416 to reduce power consumption by writing a 0 to
the BUF bit. Write a 1 to this bit to enable the buffer. Use
the internal buffer when acquiring high source-imped-
ance input signals.
FSYNC:
Conversion-Start Bit. Set FSYNC = 0 to begin calibration
or conversion. The MAX1415/MAX1416 perform free-run-
ning conversions while FSYNC = 0. Set FSYNC = 1 to
stop converting data and to hold the nodes of the digital
filter, the filter-control logic, the calibration-control logic,
and the analog modulator in a reset state. The
DRDY
output does not reset high if it is low (indicating that valid
data has not yet been read from the data register) when
FSYNC goes high. To clear
DRDY
output, read the data
register.
