PIN FUNCTION DESCRIPTIONS
Mnemonic
Description
VIN1 to VIN8
Analog Input Channels. The AD7822 has a single input channel; the AD7825 and AD7829 have four and eight
analog input channels respectively. The inputs have an input span of 2.5 V and 2 V depending on the sup-
ply voltage (VDD). This span may be centered anywhere in the range AGND to VDD using the VMID Pin. The
default input range (VMID unconnected) is AGND to 2 V (VDD = 3 V
± 10%) or AGND to 2.5 V (VDD = 5 V
± 10%). See Analog Input section of the data sheet for more information.
VDD
Positive supply voltage, 3 V
± 10% and 5 V ± 10%.
AGND
Analog Ground. Ground reference for track/hold, comparators, reference circuit and multiplexer.
DGND
Digital Ground. Ground reference for digital circuitry.
CONVST
Logic Input Signal. The convert start signal initiates an 8-bit analog-to-digital conversion on the falling edge of
this signal. The falling edge of this signal places the track/hold in hold mode. The track/hold goes into track
mode again 120 ns after the start of a conversion. The state of the CONVST signal is checked at the end of
a conversion. If it is logic low, the AD7822/AD7825/AD7829 will power down. (See Operating Modes section
of the data sheet.)
EOC
Logic Output. The End of Conversion signal indicates when a conversion has finished. The signal can be used
to interrupt a microcontroller when a conversion has finished or latch data into a gate array. (See Parallel Inter-
face section of this data sheet.)
CS
Logic input signal. The chip select signal is used to enable the parallel port of the AD7822, AD7825, and AD7829.
This is necessary if the ADC is sharing a common data bus with another device.
PD
Logic Input. The Power-Down pin is present on the AD7822 and AD7825 only. Bringing the PD pin low
places the AD7822 and AD7825 in Power-Down mode. The ADCs will power up when PD is brought logic
high again.
RD
Logic Input Signal. The read signal is used to take the output buffers out of their high impedance state and
drive data onto the data bus. The signal is internally gated with the CS signal. Both RD and CS must be logic
low to enable the data bus.
A0–A2
Channel Address Inputs. The address of the next multiplexer channel must be present on these inputs when the
RD signal goes low.
DB0–DB7
Data Output Lines. They are normally held in a high impedance state. Data is driven onto the data bus when
both RD and CS go active low.
VREF IN/OUT
Analog Input and Output. An external reference can be connected to the AD7822, AD7825, and AD7829 at this
pin. The on-chip reference is also available at this pin. When using the internal reference, this pin can be
left unconnected or, in some cases, it can be decoupled to AGND with a 0.1 F capacitor.
