TOKYO, May 07, 2019 (GLOBE NEWSWIRE) -- Leading semiconductor test equipment supplier Advantest Corporation (TSE: 6857) has introduced its GPWGD high-resolution module featuring the industry’s highest analog-performance digitizer, which supports testing of high-resolution audio digital-to-analog converters (DACs) embedded in power-management ICs (PMICs) as well as stand-alone high-resolution audio devices. The module’s innovative measurement technique performs over an ultra-high dynamic range, achieving unprecedented accuracy in analog testing from device characterization to mass production without requiring complex performance boards or additional test and measurement instruments on the T2000 test platform.
High-resolution audio features both a wider dynamic range and an improved sound source compared to CDs. The proliferation of electronic devices capable of supporting high-resolution audio – including smart phones, wireless audio components for wearable electronics and home theaters, automotive navigation systems, gaming consoles, 4K and 8K televisions, and other next-generation products – has led to an increase in the number of PMICs with embedded digital-to-analog converters (DACs), which require high-dynamic-range testing with 24-bit or 32-bit resolution.
When used on the T2000 platform, the GPWGD high-resolution module provides the versatility to test both PMICs and high-resolution audio DACs using the same system configuration. This helps users to save on their capital investments while also reducing test cycle times.
The module’s upward compatibility and the high-resolution functionality of its digitizer enable industry-leading measurements with both a signal-to-noise ratio (SNR) and a dynamic range (DR) of 130 dB, surpassing the analog performance of other testers typically used by developers of audio ICs. In addition, the unit’s massive parallel site testing capability leverages twice the number of sites compared to other systems on the market, resulting in higher throughput and a lower cost of test.
The new GPWGD high-resolution module’s extendible design allows it to be seamlessly integrated into either laboratory or production environments for existing device types as well as new high-resolution audio ICs.
