Description

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 50Ω, 500Ω, or 1 kΩ.

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 2.5µs 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 MAX5167 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.
