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 with 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 clamping between two external reference voltages. The MAX5165 is available with an output impedance of 50Ω, 500Ω, or 1kΩ, allowing output filtering. The MAX5165 operates with +10V and -5V supplies and a separate +5V digital logic supply.
