Features
Description
• Resolution ±0.5 LSB (DNL) . . . . . . . . . . . . . . . . . . . 8-Bit The HI1176 is an 8-bit, CMOS analog-to-digital converter for

video use that features a sync clamp function. The adoption
of a 2-step parallel method realizes low power consumption
/SLuobwjePcot w(8e-rBCiotn, s2u0mMptSioPnSa,t F20laMshSPAS/D(TyCp)onverter) and a maximum conversion speed of 20 MSPS. For higher
