MB40166/MB40176
1-CHANNEL 6-BIT AD/DA CONVERTER WITH CLAMP CIRCUIT
Fujitsu MB40166 MB40176 power 6-bit AD/DA converter which fabricated with Fujitsu Advanced Bipolar Technology. MB40166 MB40176 have same basic circuits functions, with only difference being that MB40166 independent analog input terminal section clamp voltage output terminal, while MB40176 analog input section internally connected with clamp circuit. Since both models contain single-chip clamp circuit reference voltage circuit, they ideal video signal processing.
