AD8273ARZ-R7
双通道音频差分放大器 Dual-Channel, Audio Difference Amplifier
Product Details
The AD8273 is a low distortion, dual-channel amplifier with internal gain setting resistors. With no external components, it can be configured as a high performance difference amplifier G = ½ or 2, inverting amplifier G = ½ or 2, or noninverting amplifier G = 1½ or 3.
The AD8273 operates on both single and dual supplies and only requires 2.5 mA maximum supply current for each amplifier. It is specified over the industrial temperature range of −40°C to +85°C and is fully RoHS compliant.
