EVALUATION KIT AVAILABLE  
MAX155/MAX156  
8-/4-Channel ADCs with Simultaneous  
T/Hs and Reference  
General Description  
Features  
The MAX155/MAX156 are high-speed, 8-bit, multichan-  
nel 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.  
● 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 Operation  
Applications  
● Phase-Sensitive Data Acquisition  
● Vibration and Waveform Analysis  
● DSP Analog Input  
● AC Power Meters  
● Portable Data Loggers  
When operating from a single +5V supply, the MAX155/  
MAX156 perform either unipolar or bipolar, single-ended  
or differential conversions. For applications requiring  
wider dynamic range or bipolar conversions around  
ground, the VSS supply pin may be connected to -5V.  
Conversions are initiated with a pulse to the WR pin, and data  
is accessed from the ADC’s RAM with a pulse to the RD pin.  
A bidirectional interface updates the channel configuration  
and provides output data. The ADC may also be wired for  
output-only operation.The MAX155 comes in 28-pin PDIP  
and wide SO packages, and the MAX156 comes in 24-pin  
narrow PDIP and 28-pin wide SO packages.  
Ordering Information appears at end of data sheet.
