THS4561 固定增益高速全差动 I/O 放大器

描述

THS4561全差动放大器（FDA）提供简单的接口，从单端源到高精度模数转换器（ADC）所需的差分输出）。该器件专为实现卓越的直流精度，低噪声和超低谐波失真而设计，非常适用于需要高精度且具有最佳信噪比（SNR）和无杂散动态范围（SFDR）的数据采集系统放大器和ADC组合。

当将直流耦合的，以地为中心的源信号连接到单电源差分输入ADC时，THS4561具有所需的负轨输入。极低的直流误差和漂移项支持新兴的16位至20位逐次逼近寄存器（SAR）输入要求。 2.85V至12.6V电源范围，灵活的输出共模设置，低电平余量，支持各种ADC输入和数模转换器（DAC）输出要求。

THS4561将作为VQFN-24封装中的THS4562提供双通道器件。
