The MAX5168 contains 32 sample/hold amplifiers and four 1-of-8 multiplexers. The logic controlling the muxes and sample/hold amplifiers combines the four muxes into a unified 1-of-32 multiplexer with a sample/hold at each output. Additional logic allows two devices to function as a single 64-channel unit. The MAX5168 is available with an output impedance of 50Ω, 500Ω, or 1kΩ. The MAX5168 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, a low droop rate, and a low hold step. The MAX5168 has a typical linearity error of less than 0.01% and can accurately acquire 8V step input signals 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. The MAX5168 is available in a 48-pin TQFP package and is specified for both the commercial (0°C to +70°C) and extended industrial (-40°C to +85°C) temperature ranges.
