CONTROL REGISTER
The arrangement of the control register is shown below. The control register is a write only register and contains 14 bits of data. The
control register is selected by putting two 1s in ADDR1 and ADDR0. The function of the bits in the control register is described
below. The power-up status of all bits is 0.

These four bits must be set to 0 when writing to the control register.

PMGT1
Power Management Bits. These two bits are used for putting the part into various power-down modes
8
PMGT0
(See Power-Down section for more details).
7
RDSLT1
Theses two bits determine which register is addressed for the read operations. See Table II.

RDSLT0
5
AMODE
Analog Mode Bit. This pin allows two different analog input ranges to be selected. A logic 0 in this bit
position selects range 0 to VREF (i.e., AIN(+) – AIN(–) = 0 to VREF). In this range AIN(+) cannot go
below AIN(–) and AIN(–) cannot go below AGND and data coding is straight binary. A logic 1 in this
bit position selects range –VREF/2 to +VREF/2 (i.e., AIN(+) – AIN(–) = –VREF /2 to +VREF/2). AIN(+)
cannot go below AGND, so for this range, AIN(–) needs to be biased to at least +VREF/2 to allow
AIN(+) to go as low as AIN(–) –VREF/2 V. Data coding is twos complement for this range.
4
CONVST
Conversion Start Bit. A logic one in this bit position starts a single conversion, and this bit is automati-
cally reset to 0 at the end of conversion. This bit may also used in conjunction with system calibration
(see Calibration section).
3
CALMD
Calibration Mode Bit. A 0 here selects self-calibration and a 1 selects a system calibration (see Table III).
2
CALSLT1
Calibration Selection Bits and Start Calibration Bit. These bits have two functions.
1
CALSLT0
With the STCAL bit set to 1, the CALSLT1 and CALSLT0 bits determine the type of calibration per-
0
STCAL
formed by the part (see Table III). The STCAL bit is automatically reset to 0 at the end of calibration.
With the STCAL bit set to 0, the CALSLT1 and CALSLT0 bits are decoded to address the calibration
register for read/write of calibration coefficients (see section on the calibration registers for more details).

00
0
A full internal calibration is initiated. First the internal DAC is calibrated, then the
internal gain error and finally the internal offset error are removed. This is the default setting.

A full system calibration is initiated. First the internal DAC is calibrated, followed by the
system gain error calibration, and finally the system offset error calibration.
