采用 TinyPak 封装的 4 MHz GBW、轨至轨输入/输出运算放大器

 

描述

The LM7301 provides high performance in a wide range of applications. The LM7301 offers greater than rail-to-rail input range, full rail-to-rail output swing, large capacitive load driving ability, and low distortion.

With only 0.6-mA supply current, the 4-MHz gain-bandwidth of this device supports new portable applications where higher power devices unacceptably drain battery life.

The LM7301 can be driven by voltages that exceed both power supply rails, thus eliminating concerns over exceeding the common-mode voltage range. The rail-to-rail output swing capability provides the maximum possible dynamic range at the output. This is particularly important when operating on low supply voltages.

Operating on supplies of 1.8 V to 32 V, the LM7301 is excellent for a very wide range of applications in low power systems.

Placing the amplifier right at the signal source reduces board size and simplifies signal routing. The LM7301 fits easily on low profile PCMCIA cards.
