MAX5167NCCM+T

P1-P3P4-P6P7-P9P10-P12
General Description
The MAX5167 contains 32 sample-and-hold amplifiers
driven by a single multiplexed input. The control logic
addressing the outputs is a simple 5-wire input to the
multiplexer. Additional logic allows two devices to function
as a single 64-channel unit. Clamping diodes on each
output allows clamping between two external
reference voltages. The MAX5167 is available with an
output impedance of 50Ω, 500Ω, or 1kΩ.
The MAX5167 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 MAX5167 has a typical linearity error
of less than 0.01% and can accurately acquire an 8V
step input signal 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 MAX5167 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.
