GENERAL DESCRIPTION
(continued from Page 1)
Each VR has its own VR latch that holds its programmed
resistance value. These VR latches are updated from an SPI-
compatible, serial-to-parallel shift register that is loaded from
a standard 3-wire, serial-input digital interface. Ten data bits
make up the data-word clocked into the serial input register.
The data-word is decoded where the first two bits determine
the address of the VR latch to be loaded, and the last eight bits
are the data. A serial data output pin at the opposite end of the
serial register allows simple daisy chaining in multiple VR
applications without additional external decoding logic.
The reset ( RS ) pin forces the wiper to midscale by loading 80
into the VR latch. The SHDN pin forces the resistor to an end-
to-end open-circuit condition on the A terminal and shorts the
wiper to the B terminal, achieving a microwatt power shutdown
state. When SHDN is returned to logic high, the previous latch
settings put the wiper in the same resistance setting prior to
shutdown. The digital interface is still active in shutdown so
that code changes can be made that will produce new wiper
positions when the device is taken out of shutdown.

The AD8400 is available in the SOIC-8 surface mount. The
AD8402 is available in both surface-mount (SOIC-14) and
14-lead PDIP packages, while the AD8403 is available in a
narrow-body, 24-lead PDIP and a 24-lead, surface-mount
package. The AD8402/AD8403 are also offered in the 1.1 mm
thin TSSOP-14/TSSOP-24 packages for PCMCIA applications.
All parts are guaranteed to operate over the extended industrial
temperature range of −40°C to +125°C.
