Details
General DescriptionThe 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.Features♦ 8 Simultaneously Sampling Track/Hold Inputs♦ 3.6µs Conversion Time Per Channel♦ Unipolar or Bipolar Input Range♦ Single-Ended or Differential Inputs♦ Mixed Input Configurations Possible♦ +2.5V Internal Reference♦ Single +5V or Dual ±5V Supply OperationApplications Phase-Sensitive Data Acquisition Vibration and Waveform Analysis DSP Analog Input AC Power Meters Portable Data Loggers
