The LMR70503 is a buck-boost converter with adjustable negative output voltage in a tiny 8-bump thin DSBGA package. Its unique control method is designed to provide fast transient response, low output noise, high efficiency, and tight regulation in the smallest possible PCB area. The LMR70503 has built in soft start, peak current limit, minimum switching frequency, and Under Voltage Lock Out (UVLO), with no external compensation required. For ease of use, the Enable pin is referred to the IC ground, instead of the lowest potential of the IC: the negative output voltage.

TIDA-00431 — 參考設(shè)計 - 采用 8GHz 直流耦合全差分放大器的 RF 采樣 4GSPS ADC
此參考設(shè)計介紹了一個寬帶射頻接收器,該接收器利用 4 GSPS 模數(shù)轉(zhuǎn)換器 (ADC) 并具有一個 8GHz 直流耦合全差動放大器前端。放大器前端提供信號增益并允許采集下行到直流的信號,而平衡-非平衡變壓器耦合輸入則做不到這一點。
