AD7811/AD7812

Control Register (AD7811)

The Control Register is a 10-bit-wide, write only register. The Control Register is written to when the AD7811 receives a falling

edge on its TFS pin. The AD7811 will maintain the same configuration until a new control byte is written to the part. The control

register can be written to at the same time data is being read. This latter feature enhances throughput rates when software control is

being used or when the analog input channels are being changed frequently. The power-up default register contents are all zeros;

therefore, when the supplies are connected, the AD7811 is powered down by default.

*This is a don’t care bit.

This is the package address bit. It is used in conjunction with the package address pin to allow two AD7811s to

share the same serial bus. The AD7811 can also share the same serial bus with the AD7812. When a control word

is written to the control register of the AD7811 the control word is ignored if the package address bit in the con-

trol byte does not match how the package address pin is hardwired. Only the serial port of the device that received

the last valid control byte, i.e., the address bit matched the address pin, will attempt to drive the serial bus on the

next serial read. When the part powers up this bit is set to 0.

PD1, PD0

These bits allow the AD7811 to be fully powered down and powered up. Bit combinations PD1 = PD0 = 0 and

PD1 = PD0 = 1 override the automatic power-down decision at the end of conversion. These bits also decide the

power-down mode when the AD7811 enters a power-down at the end of a conversion. There are two power-down

modes—Full Power-Down and Partial Power-Down. See Power-Down Options section of this data sheet.

V_IN4/AGND

DIF/SGL

The DIF/SGL bit in the control register must be set to 0 to use this option otherwise this bit is ignored. Setting

_IN4/AGND to 0 configures the analog inputs of the AD7811 as four single-ended analog inputs referenced to

analog ground (AGND). By setting this bit to 1 the input channels V_IN1to V_IN3are configured as three pseudo-

differential channels with respect to V_IN4—see Table I.

This bit is used to configure the analog inputs as single ended or pseudo differential pairs. By setting this bit to 0

the analog inputs can be configured as single ended with respect to AGND, or pseudo differential with respect to

_IN4as explained above. Setting this bit to 1 configures the analog input channels as two pseudo differential pairs

_IN1/V_IN2and V_IN3/V_IN4—see Table I.

CH1, CH0

These bits are used in conjunction with V_IN4/AGND and DIF/SGL to select an analog input channel. The table

shows how the various channel selections are made—see Table I.

CONVST

Setting this bit to a logic one initiates a conversion. A conversion is initiated 400 ns after a write to the control

initiated in the same serial write. The bit is reset after the end of a conversion.

EXTREF

This bit must be set to a logic one if the user wishes to use an external reference or use V_DDas the reference.

When the external reference is selected the on chip reference circuitry powers down.
