ADV7123JSTZ240-RL

Digital To Analog Converters Overview

The ADV7123JSTZ240-RL is a triple high-speed video digital-to-analog converter (DAC) fabricated in a monolithic CMOS process. It integrates three independent 10-bit DACs with complementary outputs, designed for high-performance video systems. The device supports a throughput rate of up to 330 MSPS and operates on a single 5 V or 3.3 V supply. Key electrical parameters include a guaranteed monotonic conversion to 10 bits, an internal 1.235 V reference voltage, and TTL-compatible digital inputs. It features low power dissipation, consuming as little as 30 mW at 3 V, and includes a standby mode reducing consumption to 6 mW typical. The component is housed in a 48-lead LQFP package.

Digital To Analog Converters Procurement Notes

Verify the specific suffix JSTZ240 against the manufacturer's current ordering guide to confirm package type, temperature range, and lead-free status. Confirm availability through authorized distributors as supply conditions may vary. Ensure compatibility with existing PCB footprints for the 48-lead LQFP package during procurement planning.

Digital To Analog Converters Selection Notes

Select this component for applications requiring high-speed RGB video conversion with minimal external reference circuitry. Verify that the system clock frequency does not exceed the specified grade limits (50 MHz, 140 MHz, 240 MHz, or 330 MHz). Ensure the RSET resistor value matches the desired full-scale output current for the chosen supply voltage (5 V or 3.3 V). Check thermal requirements for the LQFP package under maximum operating conditions.

Digital To Analog Converters Part Context

The ADV7123 belongs to Analog Devices' high-speed video DAC family. It is part of the ADV series, which includes various resolutions and speeds. The 'J' indicates industrial temperature range (-40°C to +85°C), 'STZ' denotes the 48-lead LQFP Pb-free package, and '240' typically refers to the speed grade or revision variant within the manufacturing line.

Digital To Analog Converters Replacement Considerations

Check the official datasheet for direct pin-compatible alternatives within the ADV712x series, such as the ADV7125 (8-bit) or other variants with different speed grades. Ensure any substitute maintains the required 10-bit resolution and 330 MSPS capability if performance parity is needed.
