32-Channel Sample/Hold Amplifier
with Output Clamping Diodes
General Description
Features
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.
o 32-Channel Sample/Hold
o Output Clamps on Each Channel
o 0.01% Accuracy of Acquired Signal
o 0.01% Linearity Error
o Fast Acquisition Time: 2.5µs
o Low Droop Rate: 1mV/s
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.
o Low Hold Step: 0.25mV
o Wide Output Voltage Range: +7V to -4V
