TMC1103

www.fairchildsemi.com TMC1103 Triple Video A/D Converter with Clamps 8-Bit, 50Msps Features 8-bit resolution 50 Msps conversion rate Low power: 100mW per channel @ 20 Msps Integral track/hold Independent Input Clamps Independent clock inputs Integral and differential linearity error 0.5 LSB Differential phase 0.7 degree Differential gain 1.8% Single +5V power supply Three-state TTL/CMOS-compatible outputs Low cost Applications Video digitizing (composite and Y-C) VGA and CCD digitizing LCD projection panels Image scanners Personal computer video boards Multimedia systems Low cost, high speed data conversion Description Incorporated into the TMC1103 are three analog-to-digital (A/D) converters, each with an independent clock, reference voltage and input clamp. Analog signals are converted to Triple 8-bit digital words at sample rates up to 50 Msps (Megasamples per second) per channel. Integral Track/Hold circuits deliver excellent performance on signals with full-scale spectral components up to 12 MHz. Innovative two-step conversion architecture and submicron CMOS technology reduce typical power dissipation to 100 mW per converter. Power is derived from a single +5 Volt power supply. Outputs are three-state outputs and TTL/CMOS-compatible. TMC1103 package is a 80-lead Metric Quad Flat Pack (MQFP). Performance specifications are guaranteed from 0°C to 70°C.
