General Description

The MAX5166 contains four 1-to-8 multiplexers and 32 sample/hold amplifiers. The sample/hold amplifiers are organized into four octal sample/holds with separate inputs and independent TTL/CMOS-compatible hold enables for each octal set. Additional 3-bit TTL/CMOS compatible address logic selects the 1-to-8 multiplexer channel. The MAX5166 is available with an output impedance of 50Ω, 500Ω, or 1kΩ, allowing output filtering.

The MAX5166 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 0.5mV of error. While in hold mode, the output voltage slowly droops at a rate of 1mV/sec. The MAX5166 is available in a 48-pin TQFP package.
