• Manufacturer: Burr-Brown Corporation

ABSOLUTE MAXIMUM RATINGS
NOTE: (1) Stresses above those listed under “Absolute Maximum Ratings” may
cause permanent damage to the device. Exposure to absolute maximum condi-
tions for extended periods may affect device reliability.

NOTE: (1) For detail drawing and dimension table, please see end of data sheet or Package Drawing File on Web. (2) Performance Grade information is marked
on the reel. (3) Models with a slash(/) are available only in Tape and reel in quantities indicated (e.g. /250 indicates 250 units per reel, /2K5 indicates 2500 devices
per reel). Ordering 2500 pieces of ”ADS7835E/2K5“ will get a single 2500-piece Tape and Reel. For detailed Tape and Reel mechanical information, refer to the
www.burr-brown.com web site under Applications and Tape and Reel Orientation and Dimensions. (4) N/S = Not Specified, typical only. However, 12-Bits no missing
codes is guaranteed over temperature.

DESCRIPTION
Reference Output. Decouple to ground with a 0.1 F ceramic capacitor and a 2.2 F tantalum capacitor.

Convert Input. Controls the sample/hold mode, start of conversion, start of serial data transfer, type of serial transfer, and power-
down mode. See the Digital Interface section for more information.
Serial Data Output. The 12-bit conversion result is serially transmitted most significant bit first with each bit valid on the rising edge
of CLK. By properly controlling the CONV input, it is possibly to have the data transmitted least significant bit first. See the Digital
Interface section for more information.
Clock Input. Synchronizes the serial data transfer and determines conversion speed.
Power Supply. Decouple to ground with a 0.1 F ceramic capacitor and a 10 F tantalum capacitor.

Electrostatic discharge can cause damage ranging from per-
formance degradation to complete device failure. Burr-Brown
Corporation recommends that all integrated circuits be
handled and stored using appropriate ESD protection meth-
ods.
ESD damage can range from subtle performance degrada-
tion to complete device failure. Precision integrated circuits
may be more susceptible to damage because very small
parametric changes could cause the device not to meet
published specifications.
