The SELECT and CONFIG pins allow the design of a

virtual 64-channel device using two of the MAX5168s.

See the Applications Information section for more infor-

mation about 64-plus output addressing schemes.

Detailed Description

Digital Interface

The MAX5168 has three logic control inputs and five

address lines. The address lines are inputs to a demul-

tiplexer that selects one of the 32 outputs in a standard

addressing scheme (Table 1). The analog input is con-

nected to the addressed sample/hold when directed by

the control logic (Table 2).

Sample/Hold

The MAX5168 contains 32 buffered sample/hold circuits

with internal hold capacitors. Internal hold capacitors

minimize leakage current, dielectric absorption,

feedthrough, and required board space. The value of

the hold capacitor affects acquisition time and droop

rate. Smaller capacitance allows faster acquisition

times but increases the droop rate. Larger values

increase hold acquisition time. The hold capacitor used

in the MAX5168 provides fast 2.5µs (typ) acquisition

time while maintaining a relatively low 1mV/s (typ)

droop rate, making the sample/hold ideal for high-

speed sampling.

The three logic control lines determine the state of the

addressed sample/hold. The normal circuit connection

for this device is to hardwire CONFIG and SELECT to

opposing logic voltages. When SELECT and CONFIG

are in opposite states (one high and the other low), the

five address lines select one of the sample/holds. Use

the S/H line to place the selected channel into sample

or hold mode. The other 31 channels will remain in hold

mode.

Sample Mode

When SELECT and CONFIG are in opposing logic states,

the S/H line controls the mode of operation. Sample mode

is entered when S/H is low. During sample mode, the

If an active-high sampling mode is desired, tie S/H and

CONFIG low. In this case, SELECT controls the

addressed channel with a high state putting that chan-

nel into sample mode.
