ADV7123JST330

Digital To Analog Converters Overview

The ADV7123JST330 is a triple high-speed, 10-bit digital-to-analog converter (DAC) fabricated in a monolithic CMOS process. It features a 330 MSPS throughput rate and operates on a single 5 V or 3.3 V supply. The device includes three independent DAC channels with complementary outputs, an internal 1.235 V reference, and TTL-compatible inputs. It supports RS-343A/RS-170 standards and offers low power dissipation of 30 mW minimum at 3 V. The component is housed in a 48-lead LQFP package and functions within an industrial temperature range of −40°C to +85°C.

Digital To Analog Converters Feature Summary

• 330 MSPS throughput rate with guaranteed monotonicity to 10 bits
• Triple 10-bit DACs with complementary outputs and 2.0 mA to 26.5 mA current range
• Internal 1.235 V voltage reference and TTL-compatible digital inputs
• Single-supply operation (5 V/3.3 V) with low standby power consumption

Digital To Analog Converters Applications

• Digital video systems (1600 × 1200 @ 100 Hz)
• High resolution color graphics
• Video signal reconstruction

Digital To Analog Converters Procurement Notes

Verify the specific suffix '330' indicates the 330 MHz grade variant when sourcing. Confirm RoHS compliance and lead-free packaging status through official manufacturer documentation. Ensure the 48-lead LQFP package matches the target PCB footprint requirements.

Digital To Analog Converters Selection Notes

Select this model for applications requiring 330 MHz clock speeds. Use RSET resistors to set full-scale output currents according to the specified equations. Ensure adequate decoupling for the analog supply pins and connect unused pixel data inputs to power or ground planes.

Digital To Analog Converters Part Context

The ADV7123 series comprises multiple speed grades including 50 MHz, 140 MHz, 240 MHz, and 330 MHz variants. The JSTZ330 designation specifically identifies the 330 MHz performance grade within the 48-lead LQFP package family.

Digital To Analog Converters Replacement Considerations

Other speed grades within the ADV7123 family may serve as functional substitutes if lower throughput rates are acceptable. Verify pin compatibility and electrical specifications against the specific application requirements before substitution.
