D_OUTA,

Serial Data Outputs. The data output is supplied to each pin as a serial data stream. The bits are clocked out

on the falling edge of the SCLK input and 12 SCLK cycles are required to access the data. The data

simultaneously appears on both pins from the simultaneous conversions of both ADCs. The data stream

D_OUTB

consists of the 12 bits of conversion data and is provided MSB first. If

is held low for a further 12 SCLK

cycles on either D_OUTA or D_OUTB, the data from the other ADC follows on the D_OUTpin. This allows data

from a simultaneous conversion on both ADCs to be gathered in serial format on either D_OUTA or D_OUT

using only one serial port. See the Serial Interface section.

ꢀ_DRIꢀE

Logic Power Supply Input. The voltage supplied at this pin determines at what voltage the interface will

operate. This pin should be decoupled to DGND. The voltage range on this pin is 2.7ꢀ to ±.2±ꢀ and may be

different to that at Aꢀ_CCand Dꢀ_CCbut should never exceed either by more than 0.3ꢀ. To achieve a

throughput rate of 1.12Msps ꢀ_DRIꢀEmust be greater than or equal to 4.7±ꢀ

Dꢀ_CC

Digital Supply ꢀoltage, 4.7±ꢀ to ±.2±ꢀ. The Dꢀ_CCand Aꢀ_CCvoltages should ideally be at the same potential.

For best performance it is recommended that Dꢀ_CCand Aꢀ_CCpins be shorted together, to ensure the voltage

difference between them never exceed 0.3 ꢀ even on a transient basis. This supply should be decoupled to

DGND. 10 µF and 100 nF decoupling capacitors should be placed on the Dꢀ_CCpin.

Analog Input Range Selection. Logic inputs. The polarity on these pins determines the input range of

the analog input channels. See Analog Inputs section and

ADDR

AGND

Multiplexer Select. Logic input. This input is used to select the pair of channels to be simultaneously

converted, either Channel 1 of both ADC A and ADC B, or Channel 2 of both ADC A and ADCB. The logic

state on this pin is latched on the rising edge of BUSY to set up the multiplexer for the next conversion.

Analog Ground. Ground reference point for all analog circuitry on the AD7366. All analog input signals and

any external reference signal should be referred to this AGND voltage. Both AGND pins should connect to

the AGND plane of a system. The AGND and DGND voltages ideally should be at the same potential and

must not be more than 0.3 ꢀ apart, even on a transient basis.

Analog Supply ꢀoltage, 4.7± ꢀ to ±.2± ꢀ. This is the supply voltage for the ADC cores. The Aꢀ_CCand Dꢀ_CC

voltages ideally should be at the same potential. For best performance it is recommended that Dꢀ_CCand

Aꢀ_CCpins be shorted together, to ensure the voltage difference between them never exceed 0.3 ꢀ even on a

transient basis. This supply should be decoupled to AGND. 10 µF and 100 nF decoupling capacitors should
