ADS7813

BASIC OPERATION

INTERNAL DATACLK

Figure 1a shows a basic circuit to operate the ADS7813 with

a

±10V input range. To begin a conversion and serial

transmission of the results from the previous conversion, a

falling edge must be provided to the CONV input. BUSY

will go LOW indicating that a conversion has started and

will stay LOW until the conversion is complete. During the

conversion, the results of the previous conversion will be

transmitted via DATA while DATACLK provides the syn-

chronous clock for the serial data. The data format is 16-bit,

Binary Two’s Complement, and MSB first. Each data bit is

valid on both the rising and falling edge of DATACLK.

BUSY is LOW during the entire serial transmission and can

be used as a frame synchronization signal.

EXTERNAL DATACLK

Figure 1b shows a basic circuit to operate the ADS7813 with

a

±10V input range. To begin a conversion, a falling edge

must be provided to the CONV input. BUSY will go LOW

indicating that a conversion has started and will stay LOW

until the conversion is complete. Just prior to BUSY rising

near the end of the conversion, the internal working register

holding the conversion result will be transferred to the

internal shift register.

The internal shift register is clocked via the DATACLK

input. The recommended method of reading the conversion

result is to provide the serial clock after the conversion has

completed. See External DATACLK under the Reading

Data section of this data sheet for more information.
