Function
2, 7
AGND
Analog Ground. Ground reference point for all circuitry on the AD7992. All analog input signals should be
referred to this GND voltage.
3
VDD
Power Supply Input. The VDD range for the AD7992 is from 2.7 V to 5.5 V.
4
VIN2/REFIN
Analog Input 2/Voltage Reference Input. In single-channel mode, this pin becomes the reference voltage input;
an external reference should be applied at this pin. The external reference input range is 1.2 V to VDD. A 0.1 F
and 1F capacitor should be tied between this pin and AGND. If Bit D6 is set to 1 in the configuration register,
the AD7992 operates in single-channel mode. In dual-channel mode, D6 in the configuration register is 0; in
this case, this pin provides the second analog input channel. The reference voltage for the AD7992 is taken
from the power supply voltage in dual-channel mode. See the Configuration Register section and Table 10.
5
VIN1
Analog Input 1. Single-ended analog input channel. The input range is 0 V to REFIN.
6
AS
Logic Input. Address select input that selects one of three I2C addresses for the AD7992, as shown in Table 6.
1
CONVST
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 s. The falling edge of CONVST places the track-and-
hold into hold mode and initiates a conversion. A power-up time of at least 1 s must be allowed for the
CONVST high pulse; otherwise, the conversion result is invalid (see the Modes of Operation section).
8
ALERT/BUSY
Digital Output. Selectable as an ALERT or BUSY output function. When configured as an ALERT, this pin acts as
an out-of-range indicator and, if enabled, becomes active when the conversion result violates the DATAHIGH or
DATALOW register values. See the Limit Registers section. When configured as a BUSY output, this pin becomes
active when a conversion is in progress. Open-drain output. An external pull-up resistor is required.
9
SDA
Digital I/O. Serial bus bidirectional data. Open-drain output. An external pull-up resistor is required.
10
SCL
Digital Input. Serial bus clock. Open-drain output. An external pull-up resistor is required.
