OPA1611AIDR

高性能双极输入音频运算放大器 High-Performance Bipolar-Input AUDIO OPERATIONAL AMPLIFIERS

DESCRIPON

The OPA1611 single and OPA1612 dual bipolar-input operational amplifiers achieve very low 1.1nV/√Hz noise density with an ultralow distortion of 0.000015% at 1kHz. The OPA1611 and OPA1612 offer rail-to-rail output swing to within 600mV with a 2kΩ load, which increases headroom and maximizes dynamic range. These devices also have a high output drive capability of ±30mA.
