MAX5165N数据手册ADI中文资料规格书

描述 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 50Ω, 500Ω, or 1kΩ, 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.
