Data Sheet CMOS, 330 MHz Triple 8-Bit High Speed Video DAC ADV7125 03097-001 FEATURES 330 MSPS throughput rate Triple 8-bit DACs RS-343A-/RS-170-compatible output Complementary outputs DAC output current range: 2.0 mA to 26.5 mA TTL-compatible inputs Internal reference (1.235 V) Single-supply +5 V/+3.3 V operation 48-lead LQFP and LFCSP Low power dissipation (30 mW minimum at 3 V) Low power standby mode (6 mW typical at 3 V) Industrial temperature range (−40°C to +85°C) RoHS compliant packages Qualified for automotive applications APPLICATIONS Digital video systems High resolution color graphics Digital radio modulation Image processing Instrumentation Video signal reconstruction Automotive infotainment units GENERAL DESCRIPTION The ADV7125 (ADV®) is a triple high speed, digital-to-analog converter (DAC) on a single monolithic chip. It consists of three high speed, 8-bit video DACs with complementary outputs, a standard TTL input interface, and a high impedance, analog output current source. The ADV7125 has three separate 8-bit-wide input ports. A single +5 V/+3.3 V power supply and clock are all that are required to make the device functional. The ADV7125 has additional video control signals, composite SYNC and BLANK, as well as a power save mode.
