CXAO42128A （双）和CXAO42128B（四）是低功率、高电压、轨对轨输入和输出运算放大器。这些设备可以在±2.25V到±15V双电源或+4.5V到+30V单电源之间工作。
CXAO42128A/B的增益带宽积为2.4MHz（典型值），而每个放大器仅消耗0.72mA。它们还提供超出供电轨的共模输入能力，以及轨对轨输出能力。这使CXAO42128A/B能够在任何电源电压下提供最大动态范围。
CXAO42128A/B还具有快速回转和沉降时间。这些特性使这些放大器成为薄膜晶体管液晶显示器（TFT-LCD）中用作电压参考缓冲器的理想选择。其他应用包括电池电源、便携式设备以及任何重要的低功耗应用。
CXAO42128A采用绿色SOIC-8和MSOP-8封装。CXAO42128B采用绿色TSSOP-14和SOIC-14封装。它们是在-40℃到+85℃的温度范围内指定的。

产品概述 返回TOP
The CXAO42128A/B have a gain-bandwidth product of 2.4MHz (TYP), while consuming only 0.72mA per amplifier. They also provide common mode input ability beyond the supply rails, as well as rail-to-rail output capability. This enables the CXAO42128A/B to offer maximum dynamic range at any supply voltage.
The CXAO42128A/B also feature fast slewing and settling times. These features make these amplifiers ideal for use as voltage reference buffers in Thin Film Transistor Liquid Crystal Displays (TFT-LCD). Other applications include battery power, portable devices, and anywhere low power consumption is important.
The CXAO42128A comes in Green SOIC-8 and MSOP-8 packages. The CXAO42128B is offered in Green TSSOP-14 and SOIC-14 packages. They are specified over the extended -40℃ to +85℃ temperature range.
