Description
The SC7125is a general-purpose three-channel digital-to-analog converter (DAC) that should be used to optimize video images. It mainly contains three matched 8-bit DACs, using an advanced, high-speed, segmented DAC structure. It uses a standard TTL input interface and a set of high output impedance analog current source differential outputs. The SC7123 has additional composite control signals. The SC7123 integrates edge-triggered input latches and a 1.235V temperature-compensated reference voltage source, providing customers with a simple and low-cost option.
