CDB5451A
CDB5451A Evaluation Board and Software
Features
General Description
The CDB5451A is an inexpensive tool designed to eval-
uate the functionality/performance of the CS5451A 6-
channel A/D Converter. In addition to this data sheet, the
CS5451A Data Sheet is required in conjunction with the
CDB5451A Evaluation Board.
Direct Shunt Sensor and Current
Transformer Interface for 3-Phase Power
On-Board Voltage Reference
On-board crystal for XIN
Digital Interface to PC
Six terminal block connectors serve as inputs to the
CS5451A’s six analog input pairs. The CDB5451A in-
cludes an optional voltage reference source for
CS5451A. A 4.096MHz crystal is provided as a source
for the CS5451A XIN pin, or an external clock source can
be supplied by the user. Digital output data from the
CS5451A is transferred to the user’s IBM-compatible PC
via the included 25-pin parallel port cable.
™
Lab Windows/CVI Evaluation Software
The CDB5451A includes PC software, allowing the user
to perform data capture (includes option for time domain
analysis, histogram analysis, and frequency domain
analysis). The software also allows real-time RMS calcu-
lation/analysis to be performed simultaneously on all six
channels.
- Real-Time RMS calculation
- Fast Fourier Transform (FFT) Analysis
- Time Domain Analysis
- Noise Histogram Analysis
