AD5293

The SDO pin contains an open-drain N-channel FET that requires

a pull-up resistor, if this function is used. As shown in Figure 32,

the SDO pin of one package must be tied to the DIN pin of the

next package. Users may need to increase the clock period because

the pull-up resistor and the capacitive loading at the SDO/DIN

interface may require an additional time delay between subsequent

devices.

RESET

A low-to-high transition of the hardware

pin loads the

RDAC register with midscale. The AD5293 can also be reset

through software by executing Command 3 (see Table 8). The

control register is restored with default settings (see Table 10).

RESISTOR PERFORMANCE MODE

This mode activates a new, patented 1% end-to-end resistor

tolerance that ensures a 1% resistor tolerance on each code,

that is, code = half scale, R_WB= 10 kΩ 100 Ω. See Table 2 to

verify which codes achieve 1% resistor tolerance. The resistor

performance mode is activated by programming Bit C2 of the

control register (see Table 9 and Table 10). The typical settling

time is shown in Figure 23.

When two AD5293 devices are daisy-chained, 32 bits of data are

required. The first 16 bits go to U2, and the second 16 bits go to U1.

pin should be held low until all 32 bits are clocked into

SDO

The serial data output pin (SDO) serves two purposes. It can be

used to read the contents of the wiper setting, using Command 2

(see Table 8), or it can be used for daisy-chaining multiple devices.

The remaining instructions are valid for daisy-chaining multiple

devices in simultaneous operations. Daisy chaining minimizes

the number of port pins required from the controlling IC.
