32-Channel Sample/Hold Amplifier
with a Single Multiplexed Input
Features
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/CMOScompatible address logic selects the 1-to-8 multiplexer
channel. Clamping diodes on each output allow clamping 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 accuracy, 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.
