TLV2553EVM-PDK Evaluation Module
1
Overview
The TLV2553EVM-PDK is a platform for evaluating the performance of the TLV2553 SAR ADC. The
evaluation kit includes the TLV2553EVM board, the precision host interface (PHI) board, and
accompanying computer software that enables the user to communicate with the ADC over USB, capture
data, and perform data analysis.
The TLV2553EVM board includes the TLV2553 SAR ADC and all the peripheral circuits and components
necessary to extract good performance from the ADC.
The PHI board primarily serves three functions:
•
Provides a communication interface from the EVM to the computer through a USB port.
•
Provides the digital input and output signals necessary to communicate with the TLV2553EVM.
•
Powers all active circuitry on the TLV2553EVM board.
Along with the TLV2553EVM and PHI controller board, this demonstration kit includes an A-to-micro-B
USB cable that is required for system setup.
1.1
TLV2553EVM-PDK Features
•
Includes hardware and software required for diagnostic testing as well as accurate performance
evaluation of the TLV2553 ADC.
•
No external power supply is necessary.
•
Ships with the PHI controller that provides a convenient interface to the EVM over a USB 2.0 (or
higher) for power delivery as well as digital input and output.
•
Easy-to-use evaluation software for all Windows
®
operating systems.
•
The software suite includes graphical tools for multichannel data capture, output code histogram
generation, and FFT analysis, as well as a provision for exporting data to a text file for post-processing.
1.2
TLV2553EVM Features
•
Onboard, precision, op-amp buffers on every analog input channel to support a high input impedance
(1 M
Ω
) and a low impedance ADC drive for optimal performance.
•
Options for driving buffer inputs close to full-scale or 0 V using onboard dc voltage sources.
•
Onboard precision voltage reference and low-impedance ADC reference drive circuit.
•
Includes a +5-V low-dropout regulator (LDO) to regulate supply voltages to the ADC and drive circuits.
•
Includes a 5-V to 3.3-V bidirectional digital level translator to interface with the host controller.
