AD8400/AD8402/AD8403

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 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.

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 ( ) pin forces the wiper to midscale by loading 80_H

SHDN

into the VR latch. The

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

SHDN

state. When

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.
