Configuration Register
The device has an 8-bit wide configuration register to
select for: input channel, conversion mode, conversion
rate, and PGA gain. This register allows the user to
change the operating condition of the device and check
the status of the device operation.
The user can rewrite the configuration byte any time
during the device operation. Register 5-1 shows the
configuration register bits.

Legend:
R = Readable bit
W = Writable bit
U = Unimplemented bit, read as ‘0’
-n = Value at POR
‘1’ = Bit is set
‘0’ = Bit is cleared
x = Bit is unknown
bit 7
RDY: Ready Bit
This bit is the data ready flag. In read mode, this bit indicates if the output register has been updated
with a latest conversion result. In One-Shot Conversion mode, writing this bit to “1” initiates a new
conversion.
Reading RDY bit with the read command:
1
= Output register has not been updated.
0
= Output register has been updated with the latest conversion result.
Writing RDY bit with the write command:
Continuous Conversion mode: No effect
One-Shot Conversion mode:
1
= Initiate a new conversion.
0
= No effect.

Select Channel 4 (MCP3428 only, treated as “01” by the MCP3426/MCP3427)
bit 4
O/C: Conversion Mode Bit
1
= Continuous Conversion Mode (Default). The device performs data conversions continuously.
0
= One-Shot Conversion Mode. The device performs a single conversion and enters a low power
standby mode until it receives another write or read command.
bit 3-2
S1-S0: Sample Rate Selection Bit
00
