The MAX5168 contains 32 sample/hold amplifiers and
four 1-of-8 multiplexers. The logic controlling the muxes
and sample/hold amplifiers combines the four muxes into
a unified 1-of-32 multiplexer with a sample/hold at each
output. Additional logic allows two devices to function as
a single 64-channel unit. The MAX5168 is available with
an output impedance of 50Ω, 500Ω, or 1kΩ.
The MAX5168 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, a low droop rate, and a low hold
step. The MAX5168 has a typical linearity error of less
than 0.01% and can accurately acquire 8V step input sig-
nals to 0.01% accuracy in 2.5µs within the +7V to -4V
input signal range. Transitions from sample mode to hold
mode result in only a 0.5mV error. While in hold mode, the
output voltage slowly droops at a rate of 1mV/s.
The MAX5168 is available in a 48-pin TQFP package and
is specified for both the commercial (0°C to +70°C) and
extended industrial (-40°C to +85°C) temperature ranges.
