32-Channel Sample/Hold Amplifier
with Four Multiplexed Inputs
General Description
The MAX5166 contains four 1-to-8 multiplexers and 32
sample/hold amplifiers. The sample/hold amplifiers are
organized into four octal sample/holds with separate
inputs and independent TTL/CMOS-compatible hold
enables for each octal set. Additional 3-bit TTL/CMOS-
compatible address logic selects the 1-to-8 multiplexer
channel. The MAX5166 is available with an output imped-
ance of 50鈩? 500鈩? or 1k鈩? allowing output filtering.
The MAX5166 operates with +10V and -5V supplies,
and a separate +5V digital logic supply. Manufactured
with a proprietary BiCMOS process, it provides high
accuracy, fast acquisition time, low droop rate, and a
low hold step. The device acquires 8V step input sig-
nals to 0.01% accuracy in 2.5碌s. Transitions from sam-
ple mode to hold mode result in only 0.5mV of error.
While in hold mode, the output voltage slowly droops at
a rate of 1mV/sec. The MAX5166 is available in a 48-pin
TQFP package.
