NXP Semiconductors TDA8706
The TDA8706 is a monolithic bipolar 6-bit Analog-to-Digital Converter (ADC) with a 3 analog input multiplexer and a clamp. The TDA8706 is a ‘like-flash’ converter which produces an output code in one clock period. The device can withstand a duty clock cycle of 50 to 66.6% (clock HIGH).FEATURES
