1 Low Voltage Operating Ω Driver Monolithic IC MM67~MM676 Series April 8, 9 Outline This IC is a Ω driver with a built-in LPF that can operate at low voltage. Operationg supply voltage supports V and 5V systems, and it is ideal for video signal output in devices ranging from portable equipment such as digital still cameras to stationary equipment such as DVD players. It incorporates a high-performance 4thorder LPF, which is ideal for removing DAC sampling noise. In addition, ultra-low current consumption has been achieved by suppressing current consumption in power-save mode to under µa. This lengthens battery life in portable devices. The built-in amp gain on these series ICs is available: 6dB/9dB/dB, thus enabling support for DAC and a variety of output amplitudes. The series offers a choise of either with or without input clamp, allowing support for a range of video signals, other than composite signals.
