MAX155ACPI集成电路（IC）的模数转换器（ADC）规格书PDF中文资料

General Description

The MAX155/MAX156 are high-speed, 8-bit, multichannel analog-to-digital converters (ADCs) with simultaneous track/holds (T/Hs) to eliminate timing differences between input channel samples. The MAX155 has 8 analog input channels and the MAX156 has 4 analog input channels. Each channel has its own T/H, and all T/Hs sample at the same instant. The ADC converts a channel in 3.6µs and stores the result in an internal 8x8 RAM. The MAX155/MAX156 also feature a 2.5V internal reference and power-down capability, providing a complete, sampling data-acquisition system.
