PRELIMINARY TECHNICAL DATA
PIN FUNCTION DESCRIPTION
Pin
Mnemonic
Function
AGND
Analog Ground. Ground reference point for all circuitry on the AD7994/AD7993. All analog
input signals should be referred to this GND voltage.
Power Supply Input. The V
DD
range for the AD7994/AD7993 is from +2.7V to +5.5V.
Voltage Reference Input. The External Reference for the AD7994/AD7993 should 0.1 μF
capacitor should be placed between the REF
IN
pin and AGND.
Analog Input 1. Single-ended analog input channel. The input range is 0V to REF
IN
.
Analog Input 3. Single-ended analog input channel. The input range is 0V to REF
IN
.
Analog Input 4. Single-ended analog input channel. The input range is 0V to REF
IN
.
Analog Input 2. Single-ended analog input channel. The input range is 0V to REF
IN
.
Logic Input. Address Select Input which selects one of three I
2
C addresses for the AD7994/
AD7993 as shown in Table I.
Logic Input Signal. Convert Start Signal. This is an edge triggered logic input. The rising
edge of this signal powers up the part. The power up time for the part is 1
μ
s. The falling
edge of
CONVST
places the track/hold into hold mode and initiates a conversion. A power
up time of at least 1
μ
s must be allowed for the
CONVST
high pulse, otherwise the conver-
sion result will be invalid. (See Modes of Operation Section)
Digital Output, selectable as an ALERT or BUSY output function. When configured as an
ALERT output, this pin acts as an Out of Range Indicator, and if enabled becomes active
when the conversion result violates the DATA
HIGH
or DATA
LOW
values. See Limit Registers
section. When configured as a BUSY output, this pin becomes active when a conversion is in
progress.
Digital I/O. Serial Bus Bi-directional Data. Open-drain output. External pull-up resistor
required.
Digital Input. Serial Bus Clock. External pull-up resistor required.
