LTC6910-2 采用 SOT-23 封装的数字控制可编程增益放大器
LTC®6910 系列是低噪声数字可编程增益放大器 (PGA),所占用的印制电路板空间非常少,并且易于使用。反相增益是可调的,当采用一个 3 位数字输入时,在 LTC6910-2中可选择数值为 0、1、2、5、10、20、50 和 100V/V 的增益;在 LTC6910-2 中可选择数值为 0、1、2、4、8、16、32 和 64V/V 的增益;而在 LTC6910-3 中则可选择数值为 0、1、2、3、4、5、6 和 7V/V 的增益。
LTC6910-X 系列是具有轨至轨输出的反相放大器。当在单位增益条件下工作时,它们也对轨至轨输入信号进行处理。位于 AGND 引脚上的一个内部生成半电源基准支持单电源应用。LTC6910-X 系列在 2.7V 至 10.5V 的单电源或分离电源条件下工作,并提供 8 引脚 SOT-23 封装。
