Monolithic IC MM1671~MM1677 Series
Outline
This IC is a 75Ω driver with a built-in LPF that can operate at low voltage. Operationg supply voltage supports
3V 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 4th-
order 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 1µA. This lengthens battery
life in portable devices.
The built-in amp gain on these series ICs is available: 6dB/9dB/12dB/16.5dB, 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.
