DescriptionThe 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 imped-ance of 50?, 500?, or 1k?, 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 sig- nals to 0.01% accuracy in 2.5s. Transitions from sam- ple 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.
