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.

参考设计

TIDA-00431 — 参考设计 - 采用 8GHz 直流耦合全差分放大器的 RF 采样 4GSPS ADC

宽带射频 (RF) 接收器有助于极大提升无线电设计中的灵活性。较宽的瞬时带宽支持灵活调节而无需改动硬件且能够以间隔较大的频率捕获多个通道。

此参考设计介绍了一个宽带射频接收器，该接收器利用 4 GSPS 模数转换器 (ADC) 并具有一个 8GHz 直流耦合全差动放大器前端。放大器前端提供信号增益并允许采集下行到直流的信号，而平衡-非平衡变压器耦合输入则做不到这一点。
