Product Details

The ADMX1001 is an ultra-low distortion sinewave and high-resolution arbitrary waveform generator with an acquisition channel. This high-performance module demonstrates a proprietary digital pre-distortion algorithm that reduces signal distortion below levels that can be achieved with high-performance digital-to-analog converters (DAC) and amplifiers alone. Its differential output can be set to common-mode levels often required to test high-performance analog-to-digital converters (ADC), audio codecs, and other audio ICs and systems. The signal generator and the acquisition channel can be individually controlled using separate, easy to use, SPI interfaces - combined with the module's small-form factor, the ADMX1001 can be easily embedded into test systems, or simply used on the bench for measurement and characterization.

APPLICATIONS

  • High-end audio test
  • Analog-to-digital converter characterization and test
  • Sensor and transducer test
  • Frequency response and network analysis
  • ATE

SCP-ADP7182-EVALZ

ADP7182 Signal Chain Evaluation Board | 200mA Low Noise Negative LDO

Buy Now View Details

Product Details

Demonstration circuit SCP-ADP7182-EVALZ is a –28V, –200mA Low Dropout (LDO) regulator designed to allow low noise operation in noise sensitive circuits. It is easily configured for a wide output range and can provide extremely quiet operation with its high PSRR.

Like all boards in the Signal Chain Power series, this board is designed to be easily plugged into other SCP boards to form a complete signal chain power system, enabling fast evaluation of low power signal chains. To evaluate this board, some universal SCP hardware is required, namely:

  • SCP-INPUT-EVALZ
  • SCP-OUTPUT-EVALZ
  • SCP-1X5BKOUT-EVALZ
  • SCP-THRUBRD-EVALZ
  • SCP-FILTER-EVALZ
  • SCP-1X2BKOUT-EVALZ
  • SCP-5X1-EVALZ

 

To properly evaluate SCP series demo boards, you will need the SCP Configurator companion software. SCP Configurator can help you choose the right board and topology for your design.

Note that the Demo Manual does not cover details important to the operation and configuration regarding the ADP7182. Please refer to the ADP7182 datasheet for a complete description of the part.

Product Details

The AD-FMComms11-EBZ board is a system platform board for communication infrastructure applications that demonstrates the Direct to RF (DRF) transmitter and observation receiver architecture. Using high sample rate RFDAC(s) and RFADC(s), a number of components in previous generation transmitters can be eliminated, such as mixers, modulators, IF amplifiers and filters. The objective being to bring the ADC or DAC as close to the antenna as possible, leading to possibly more cost effective and efficient communications solution.

It is composed of multi-GSPS RF ADC and DAC, AD9625 and AD9162 respectively. The transmit path contains a balun, low pass filter, gain block and variable attenuation to produce an output appropriate for a power amplifier module. Along the observation path, the PA output is coupled back into the board through a variable attenuator, a balun and finally the ADC. Clock management is taken care of on board; all the necessary clocks are generated from a reference. Power management is present as well.
