The MAX5167 contains 32 sample-and-hold amplifiers driven by a single multiplexed input. The control logic addressing the outputs is a simple 5-wire input to the multiplexer. Additional logic allows two devices to function as a single 64-channel unit. Clamping diodes on each output allows clamping between two external reference voltages. The MAX5167 is available with an output impedance of 50, 500, or 1k. The MAX5167 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 MAX5167 has a typical linearity error of less than 0.01% and can accurately acquire an 8V step input signal to 0.01% accuracy in 2.5s 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.
