The MN3304 is a 512-stage ultra low voltage BBD variable delay line with a wide supply voltage range of 1.8 to 5.0 V, no insertion loss, wide dynamic range and low distortion. It is suitable for use as reverberation effect of low voltage operation audio equipment such as portable stereo, radio cassette recorder and microphone.
The MN3304 is a 512‑stage bucket‑brigade device (BBD) designed for ultra‑low‑voltage audio applications such as portable stereos, cassette recorders and microphones. It operates from a +3 V supply and provides a variable delay from 0.256 ms up to 25.6 ms.
Key features include a wide supply voltage range (1.8‑5 V), no insertion loss, a signal‑to‑noise ratio of 73 dB, low distortion (0.7 % THD), and a clock frequency range of 10 kHz to 200 kHz. The device is supplied in an 8‑pin dual‑in‑line plastic (DIP) package.
