The ADS5407 is a high linearity dual channel 12-bit, 500 MSPS analog-to-digital converter (ADC) easing front end filter design for wide bandwidth receivers. The analog input buffer isolates the internal switching of the on-chip track-and-hold from disturbing the signal source as well as providing a high-impedance input. Optionally the output data can be decimated by two. Designed for high SFDR, the ADC has low-noise performance and outstanding spurious-free dynamic range over a large input-frequency range. The device is available in a 196 pin BGA package and is specified over the full industrial temperature range (–40°C to 85°C).

類比工程師的計算機旨在加速類比電路設計工程師定期使用的許多重複計算。此基於 PC 的工具提供圖形介面,列出各種常見計算,從使用回饋電阻器設定運算放大器增益到選擇適當的電路設計元件以穩定類比數位轉換器 (ADC) 驅動緩衝電路。

除了作為獨立工具使用外,此計算機還與類比工程師口袋參考中描述的概念相得益彰。

PMP9767 — 適用於 12 位元 500 MSPS ADC 的免 LDO 電源參考設計

資料轉換器的電氣性能取決於其供應電壓的清潔度。一般使用線性穩壓器 (LDO),但其具有低效率與高功率損耗,不適合可攜式應用。

改用 TPS62231 和 TPS62237 等切換模式電源供應器 (SMPS),是符合成本效益且有效率的電源供應器解決方案。這種解決方案不會降低 12 位元 ADS540x 系列類比轉數位轉換器 (ADC) 的性能,且不會浪費過多電源。測試報告顯示兩個電源供應器之間的訊號雜訊比 (SNR) 和無雜散動態範圍 (SFDR) 比較,展示相同的性能。
