Pin Descriptions
Connection Notes
1.
All inputs and outputs are labeled with plus (+) and minus (-) signs. Polarity is labeled for reference and can be
selected externally by reversing pin connections.
2.
All analog output pins are “hard-wired” to internal output devices and should be left open if not used. V
V
OUT-
should not be tied together as unnecessary power will be dissipated.
3.
When the signal input is single-ended, the other half of the unused differential input must be connected to a DC
common-mode reference (usually VREF
OUT
, 2.5V).

Description
Test Mode Select
Serial interface logic mode select pin (input). JTAG interface
mode only.
Serial interface logic clock pin (input). JTAG and SPI interface
modes.
Serial interface logic pin (input) for both JTAG and SPI opera-
tion modes.
Serial interface logic pin (output) for both JTAG and SPI opera-
tion modes. Input data valid on falling edge of TCK (JTAG), or
on rising edge of CS (SPI).
Chip select logic input pin. SPI data latch.
Digital pin (input). Commands an auto-calibration sequence on
a rising edge.
Enable SPI logic input pin. When high, causes serial port to run
in SPI mode.
Ground pin. Should normally be connected to the analog
ground plane.
