The TPS723xx-Q1 family of low-dropout (LDO) negative voltage regulators offers an ideal combination of features to support low-noise applications. This device is capable of operating with input voltages from –10 V to –2.7 V. The TPS72325-Q1 regulator is stable with small, low-cost ceramic capacitors, and includes enable (EN) and noise-reduction (NR) functions. Internal detection and shutdown logic provide thermal short-circuit and overcurrent protection. High PSRR (65 dB at 1 kHz) and low noise (60 µVRMS) make the TPS723xx-Q1 ideal for low-noise applications.

The TPS723xx-Q1 uses a precision voltage reference to achieve 2% overall accuracy over load, line, and temperature variations. Available in a small SOT23-5 package, the TPS723xx-Q1 specification covers the full temperature range of –40°C to 125°C.

參考設(shè)計(jì)

PMP30473 — 超低噪聲輔助雙輸出電源參考設(shè)計(jì)

該參考設(shè)計(jì)是一個(gè) 2 x 1W 反相降壓/升壓轉(zhuǎn)換器。兩個(gè)輸出電壓（+5V 和 -5V）由單個(gè)降壓器件 (TPS57160-Q1) 生成。后置穩(wěn)壓器（和后置濾波器）確保輸出電壓無(wú)紋波。輸入電壓范圍涵蓋汽車和工業(yè)應(yīng)用。?

參考設(shè)計(jì)

TIDA-00431 — 參考設(shè)計(jì) - 采用 8GHz 直流耦合全差分放大器的 RF 采樣 4GSPS ADC

寬帶射頻 (RF) 接收器有助于極大提升無(wú)線電設(shè)計(jì)中的靈活性。較寬的瞬時(shí)帶寬支持靈活調(diào)節(jié)而無(wú)需改動(dòng)硬件且能夠以間隔較大的頻率捕獲多個(gè)通道。

此參考設(shè)計(jì)介紹了一個(gè)寬帶射頻接收器，該接收器利用 4 GSPS 模數(shù)轉(zhuǎn)換器 (ADC) 并具有一個(gè) 8GHz 直流耦合全差動(dòng)放大器前端。放大器前端提供信號(hào)增益并允許采集下行到直流的信號(hào)，而平衡-非平衡變壓器耦合輸入則做不到這一點(diǎn)。
