Product Details |
The MAX155 is an 8-channel, 8-bit analog to digital converter with
simultaneous track/holds for each channel. The conversion time is 3.6µs and
the result is stored in an internal RAM.
The converter operates from a single +5V power supply or
dual ±5V supplies. The converter accepts either unipolar or bipolar inputs.
The MAX155 includes an internal 2.5V voltage reference and a power down capability.
Features
- 8 Simultaneously Sampling Track/Hold Inputs
- 3.6µs Conversion Time per Channel
- Unipolor or Bipolar Input Range
- Single-Ended or Differential Inputs
- Mixed Input Configurations Possible
- +2.5V Internal Reference
- Single +5V or Dual ±5V Supply Operation
