3 说明

LMH6702QML-SP 是一款超宽带、直流耦合、单片运算放大器,专为需要出色信号保真度的宽动态范围系统而设计。得益于采用 TI 的电流反馈架构,LMH6702QML-SP 可以出色的速度提供单位增益稳定性,无需外部补偿。

LMH6702QML-SP 具有 720MHz 带宽(AV = 2V/V,VO = 2VPP)、60MHz 范围内的 10 位失真水平 (RL = 100Ω)、1.83nV/√Hz 输入基准噪声和 12.5mA 电源电流,是适用于高速 Flash 模数 (A/D) 和数模 (D/A) 转换器的出色驱动器或缓冲器。

LMH6702QML-SP 对于需要宽带放大器提供出色信号纯度的宽动态范围系统(例如雷达和通信接收器)颇有益处。低输入基准噪声以及低谐波和互调失真使得该器件非常适合高速应用。

LMH6702QML-SP 采用 TI 的 VIP10 互补双极工艺和 TI 成熟的电流反馈架构构建而成。

(1) Operation outside the Absolute Maximum Ratings may cause permanent device damage. Absolute Maximum Ratings do not imply functional operation of the device at these or any other conditions beyond those listed under Recommended Operating Conditions. If used outside the Recommended Operating Conditions but within the Absolute Maximum Ratings, the device may not be fully functional, and this may affect device reliability, functionality, performance, and shorten the device lifetime.
(2) The maximum power dissipation must be derated at elevated temperatures and is dictated by TJmax (maximum junction temperature), θJA (package junction to ambient thermal resistance), and TA (ambient temperature). The maximum allowable power dissipation at any temperature is PDmax = (TJmax – TA) / θJA or the number given in the Absolute Maximum Ratings, whichever is lower.
(3) Human body model, 1.5kΩ in series with 100pF.

5.2 Recommended Operating Conditions

VALUE
Supply voltage (VCC) ±5VDC to ±6VDC
Gain ±1 to ±10
