EL5170和EL5370是高性能差分放大器，专为驱动双绞线设计，适用于组件视频等应用场景。EL5170提供单通道配置，EL5370则支持三通道集成，两者均具备固定增益为2的功能。输入信号可接受单端或差分形式，输出始终为差分模式，便于直接驱动双绞线或差分负载。产品采用标准封装，包括SO和MSOP选项，工作温度范围为-40°C至+85°C，确保在宽温环境下稳定运行。这些放大器通过优化设计，简化了信号传输接口，满足工业级应用需求。
关键特性包括100MHz的-3dB带宽和1200V/μs的压摆率，提供快速信号响应能力。电源支持单5V或双±5V供电，总电压范围4.75V至11V，输出电流最大达±50mA（EL5170）或±70mA（EL5370），并内置短路保护机制。功耗较低，每通道典型值为7.4mA，同时配备禁用功能，通过EN引脚控制可将功耗降至微安级。输出共模电平由VREF引脚设置，其带宽超过70MHz，输入支持±2.3V的差分范围，并具备高共模抑制比（CMRR），确保信号完整性。
应用场景广泛，包括驱动双绞线用于组件视频传输、差分线路驱动、VGA over twisted-pairs实现视频信号扩展，以及ADSL/HDSL通信系统的信号放大。此外，产品支持单端转差分信号转换，适用于噪声环境中的模拟信号传输，如工业传感器接口或医疗设备，提供可靠的高带宽解决方案。
