32-Channel Sample/Hold Amplifier with Four Multiplexed Inputs
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/CMOScompatible address logic selects the 1-to-8 multiplexer channel. The MAX5166 is available with an output impedance 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 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. o Quad, 8-Channel Sample/Hold o 0.01% Accuracy of Acquired Signal o 0.01% Linearity Error o Fast Acquisition Time: 2.5µs o Low Droop Rate: 1mV/sec o Low Hold Step: 0.25mV o Wide Output Voltage Range: +7V to -4V

Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

Note 1: Guaranteed by design. Note 2: Only one M_ input may be asserted low at a time, so only one channel is selected (see Single vs. Simultaneous Sampling). Note 3: Do not exceed the absolute maximum rating for VDD to VSS of +15.75V (see Absolute Maximum Ratings).
