Description
Max5165 32-channel Sample/hold Amplifier With A Single Multiplexed Input
Manufacturer
Maxim Integrated Products, Inc.
Datasheet
The MAX5165 contains four 1-to-8 multiplexers and 32
sample/hold amplifiers. A single analog input connects
to all four internal 1-to-8 multiplexers. The sample/hold
amplifiers are organized into four octal sample/holds
with independent TTL/CMOS-compatible track/hold
enables for each octal set. Additional 3-bit TTL/CMOS-
compatible address logic selects the 1-to-8 multiplexer
channel. Clamping diodes on each output allow clamp-
ing between two external reference voltages. The
MAX5165 is available with an output impedance of
50Ω, 500Ω, or 1kΩ, allowing output filtering.
The MAX5165 operates with +10V and -5V supplies and
a separate +5V digital logic supply. Manufactured with
a proprietary BiCMOS process, it provides high accura-
cy, fast acquisition time, low droop rate, and a low hold
step. The device acquires 8V step input signals to
0.01% accuracy in 2.5µs. 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/sec. The MAX5165 is available in a 48-pin TQFP
package.
