MAX536/MAX537
When daisy-chaining MAX536s, the delay from CS
low to SCK high (tCSS) must be the greater of:
tDV + tDS
or
tTR + tRC + tDS - tCSW
where tRC is the time constant of the external pullup resistor
(Rp) and the load capacitance (C) at SDO. For tRC < 20ns,
tCSS is simply tDV + tDS. Calculate tRC from the following
equation:
tRC = Rp (C)
ln
where VPULLUP is the voltage to which the pullup resistor is
connected.
Additionally, when daisy-chaining devices, the maximum
clock frequency is limited to:
1
fSCK(max) = ——————————————
2 (tDO + tRC - 38ns + tDS)
For example, with tRC = 23ns (5V ±10% supply with
Rp = 1k
and C = 30pF), the maximum clock frequency is
8.7MHz.
Figure 9 shows an alternate method of connecting several
MAX536/MAX537s. In this configuration, the data bus is
common to all devices; data is not shifted through a
daisy-chain. More I/O lines are required in this configu-
ration because a dedicated chip-select input (CS) is
required for each IC.

“X” = Don’t Care. LDAC provides true latch control: when LDAC is low, the DAC registers are transparent; when LDAC is high,
the DAC registers are latched.
Mode 0, DOUT clocked out on SCK’s falling edge. All DACs
updated from their respective input registers.
Mode 1 (default condition at power-up), DOUT clocked out on
SCK’s rising edge. All DACs updated from their respective
input registers.
