See AD7998 and AD7992 for 8-channel and 2-channel
equivalent devices, respectively. VDD The AD7993/AD7994 provide a 2-wire serial interface that is
compatible with I2C interfaces. Each part comes in two versions,
AD7993-0/AD7994-0 and AD7993-1/AD7994-1, and each
version allows for at least two different I2C addresses. The I2C
interface on the AD7993-0/AD7994-0 supports standard and
fast I2C interface modes. The I2C interface on the AD7993-1/ …

Errata Sheet Please be advised that it was necessary to change the pin-out diagram for the AD7994/AD7993 ADCs. Please
discard any pin-out information from AD7994/AD7993 data sheets up to and including Rev PrD.
Packaged material may be identified by the date code; parts with date code 0311 have the old pin-out and will be
no longer manufactured. All other date-coded material will be manufactured according to the new pin-out diagram
which is shown below. AGND 1 AGND 2 AGND 3 AGND 4 AD7994 16 AGND 15 SCL 14 SDA TOP VIEW 13 ALERT (Not to Scale) 12 CONVST VDD 5 REFIN 6 11 AS VIN1 7 10 VIN2 VIN3 8 9 VIN4 REV. A Sept 2003
