The LT6604IUFF-10#PBF is an integrated circuit (IC) made by Analog Devices. It is a dual differential amplifier and 10MHz lowpass filter. The dual differential amplifier contains two voltage feedback amplifiers which have differential input structures, allowing them to offer differential operations. These amplifiers also provide an extremely low offset voltage and wide gain bandwidth product, making them ideal for various audio and communications applications. Additionally, both amplifiers feature low input bias current, and their output can be set up to provide single-ended or dual-differential output.The 10MHz lowpass filter is designed to reduce high-frequency noise and artifacts from signal transmission lines. It features high cut-off frequency precision, low passband distortion, and good stopband attenuation, making it perfect for filtering signals. This part is suitable for an array of audio and communications applications such as high-performance microphones, instrumentation, and telephony.
