[原创] Maxim MAX40026 280ps高速超低功耗比较器解决方案

Maxim公司的MAX40026是单电源高速超低功耗比较器,典型传输时延为280ps,输入共模范围为1.5V到VDD+0.1V,输出级是LVDS,有助于最小化功耗和直接和许多FPGA和CPU直接接口,每个输出线的互补输出有助于抑制共模噪音.工作电压2.7V-3.6V,2.7V时的功耗为39.4mW,工作温度-40℃ 到 +125℃,满足汽车AEC-Q100规范.主要用在LIDAR, RADAR和SONAR的距离检测, 飞行时间传感器,高速差分线路接收器,示波器的高速触发,通信,振荡器,阈值检测器,高速电平转移,测试和测量以及汽车电子.本文介绍了MAX40026主要优势和特性,单端和差分端输出接收器框图,以及评估板MAX40026 EVK主要特性,电路图,材料清单和PCB设计图.

The MAX40025 and MAX40026 are single-supply, high-speed comparators with a typical propagation delay of 280ps. The overdrive dispersion is extremely low (typical 25ps), making these comparators ideal for time-of-flight distance measurement applications.

The input common mode range of 1.5V to VDD + 0.1V is compatible with the output swings of several widely used high-speed trans-impedance amplifiers, such as the MAX40658.

The output stage is LVDS (Low-Voltage Differential Sig-naling), which helps to minimize power dissipation and in-terfaces directly with many FPGAs and CPUs. Comple-mentary outputs help in suppression of common-mode noise on each output line.
