32-Channel Sample/Hold Amplifier with a Single Multiplexed Input
General Description
The MAX5165 contains four 1-to-8 multiplexers and 32 sample/hold amplifiers. A single analog input connects to all four internal 1-to-8 multiplexers. The sample/hold amplifiers are organized into four octal sample/holds w i t h independent TTL/CMOS-compatible track/hold enables for each octal set. Additional 3-bit TTL/CMOScompatible address logic selects the 1-to-8 multiplexer channel. Clamping diodes on each output allow clampi n g between two external reference voltages. The M A X 5 1 6 5 is available with an output impedance of 50, 500, or 1k, allowing output filtering. The MAX5165 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 s t e p . The device acquires 8V step input signals to 0 . 0 1 % accuracy in 2.5µs. 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/sec. The MAX5165 is available in a 48-pin TQFP package. o 32-Channel Sample/Hold o Output Clamping 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).
