说明

OPA1655 和 OPA1656 (OPA165x) 是 Burr-Brown™ 运算放大器,专为音频和工业应用而设计,在这些应用中保持信号保真度至关重要。FET 输入架构可达到 2.9nV/√Hz 的低电压噪声密度和 6fA/√Hz 电流噪声密度,能够在各种电路内将噪声降到超低。OPA165x 采用高带宽和高开环增益设计,在 20kHz 时的失真率低至 0.000035% (–129dB) 并且可提高全音频带宽内的音频信号保真。该器件还具有出色的输出电流驱动功能,在 2kΩ 负载下提供 250mV 电源电压范围内的轨到轨输出摆幅,并且可以提供 100mA 输出电流。

OPA165x 可在 ±2.25V 至 ±18V 的超宽电源电压范围内工作,也可在仅为 3.9mA 的电源电流(4.5V 至 36V)下工作,从而满足许多类型的音频米6体育平台手机版_好二三四的电源限制。它的额定工作温度范围为 –40°C 至 +125°C。
