Product Overview
The ADV7125KSTZ50 is a single-chip triple 8-bit video DAC from Analog Devices. It supports up to 50 MSPS sampling rate, accepts RGB or YPbPr digital video signals and integrates sync & blanking control logic. It can directly drive 75Ω video coaxial cables without external amplifiers. Supporting 3.3V and 5V power supply, this industrial-grade device applies to embedded display, industrial monitoring and video signal reconstruction.
Core Advantages
Triple Independent 8-bit DAC Channels
Three DAC channels for RGB output, supporting 24-bit true color display with guaranteed monotonic performance.
Direct 75Ω Cable Driving Capacity
Built-in high-current output stage, directly drives double-terminated 75-ohm video lines and reduces peripheral costs.
Dual Voltage Power Supply Support
Compatible with 3.3V and 5V power rails, easy to match various embedded hardware platforms.
Low Power Consumption with Standby Mode
Typical power consumption 30mW @3.3V; standby power ~6mW, suitable for battery-powered equipment.

Frequently Asked Questions
Q1: What does suffix KSTZ50 mean for ADV7125KSTZ50?
A1: KSTZ means lead-free 48-LQFP industrial grade package. 50 stands for max 50MSPS sampling rate. Do not interchange with ADV7125KSTZ140 or ADV7125JSTZ330.
Q2: Can ADV7125KSTZ50 directly drive analog VGA monitors?
A2: Yes. Its analog outputs support direct connection to double-terminated 75Ω coaxial cables without extra buffer amplifiers.
Q3: Can I replace ADV7125KSTZ140 with ADV7125KSTZ50 directly?
A3: Not recommended. KSTZ140 supports 140MSPS higher bandwidth. It will cause display abnormality if your system requires rate over 50MSPS.
Q4: Are there alternative brands compatible with ADV7125 series?
A4: TI TLV5638 can work for low-end video projects, but pinout and timing differ. Hardware redesign is required for direct replacement.
Q5: Does this chip support YPbPr component video output?
A5: Yes. Three DAC channels can be configured for YPbPr differential signal output for component video equipment.
Q6: What is the difference between commercial and industrial grade video DAC?
A6: ADV7125KSTZ50 supports -40~+85℃ wide temperature range. Commercial versions usually only cover 0~70℃, unsuitable for outdoor industrial devices.
Q7: What should I do if long lead time affects my project schedule?
A7: We can provide equivalent compatible schemes after confirming your working frequency and temperature requirements. Contact us to evaluate alternative models in advance.
