(1) Component qualification in accordance with JEDEC and industry standards to ensure reliable operation over specified temperature range. This includes, but is not limited to, Highly Accelerated Stress Test (HAST) or biased 85/85, temperature cycle, autoclave or unbiased HAST, electromigration, bond intermetallic life, and mold compound life. Such qualification testing should not be viewed as justifying use of this component beyond specified performance and environmental limits.

The TPS793xx family of low-dropout (LDO) low-power linear voltage regulators features high power-supply rejection ratio (PSRR), ultralow noise, fast start-up, and excellent line and load transient responses in a small-outline SOT23 package. Each device in the family is stable, with a small 2.2-µF ceramic capacitor on the output. The TPS793xx family uses an advanced, proprietary, BiCMOS fabrication process to yield extremely low dropout voltages (e.g., 112 mV at 200 mA, TPS79330). Each device achieves fast start-up times (approximately 50 µs with a 0.001-µF bypass capacitor), while consuming very low quiescent current (170 µA typical). Moreover, when the device is placed in standby mode, the supply current is reduced to less than 1 µA. The TPS79328 exhibits approximately 32 µVRMS of output voltage noise with a 0.1-µF bypass capacitor. Applications with analog components that are noise sensitive, such as portable RF electronics, benefit from the high PSRR and low-noise features, as well as the fast response time.

TIDA-00431 — 採用 8 GHz DC 耦合差動放大器的射頻取樣 4 GSPS ADC 參考設計
寬頻射頻 (RF) 接收器可大幅提高無線電設計的靈活性。寬廣的瞬時頻寬允許在不更換硬體的情況下進行靈活調諧，並能夠擷取頻率相差很大的多個通道。
此參考設計說明了一種寬頻 RF 接收器，它採用 4GSPS 類比數位轉換器 (ADC)，並具有 8GHz DC 耦合全差動放大器前端。放大器前端提供訊號增益，並允許擷取低至 DC 的訊號。這是使用平衡不平衡轉換器耦合輸入時無法實現的。
