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 with independent TTL/CMOS-compatible track/hold enables for each octal set. Additional 3-bit TTL/CMOS compatible address logic selects the 1-to-8 multiplexer channel. Clamping diodes on each output allow clamping between two external reference voltages. The MAX5165 is available with an output impedance of 50â¦, 500â¦, or 1kâ¦, 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 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 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.
