Replacement verdict
Compatible functional replacement candidate
The AD9764ARZ and AD9760ARU50RL7 are both 10-bit high-speed CMOS DACs from Analog Devices with matching resolution, supply voltage, and current-output architecture, making them functionally comparable in many designs. However, they differ in package footprint, update rate, and specified operating temperature range, so the AD9760ARU50RL7 should be treated as a candidate replacement only after validating board layout, timing margin, and thermal requirements against the target application.

Key electrical and mechanical differences between the two devices
| Parameter | AD9764ARZ | AD9760ARU50RL7 | Why it matters |
|---|---|---|---|
| Resolution | 14 bit | 10 bit | Higher resolution provides finer output granularity and lower quantization error, so a 14-bit part is not a drop-in substitute for a 10-bit design. |
| Number of DAC Channels | 1 | 1 | Both are single-channel DACs, so channel count is compatible for substitution. |
| Sampling Rate (Max) | 125 MSPS | 125 MSPS | Matching update rates allow the parts to support the same signal bandwidth in a given application. |
| Output Type | Current - Unbuffered | Current - Unbuffered | Identical current-output architecture means the external output stage and termination design can remain the same. |
| Supply Voltage | 2.7 V to 5.5 V | 2.7 V to 5.5 V | Compatible supply ranges allow operation from the same rails without redesigning the power tree. |
| Package / Case | 28-SOIC | 28-TSSOP | Different package footprints require PCB layout changes, so the parts are not physically interchangeable without a board revision. |
| Operating Temperature Range | -40°C to 85°C | -40°C to 85°C | Matching temperature ratings ensure both parts meet the same environmental requirements. |
| Mounting Type | Surface Mount | Surface Mount | Both are surface-mount devices, compatible with the same assembly process. |

Frequently asked questions
What are the key differences between the AD9764ARZ and AD9760ARU50RL7?
The AD9764ARZ is a 14-bit, 125 MSPS TxDAC digital-to-analog converter in a 28-lead SOIC package, while the AD9760ARU50RL7 is a 10-bit, 125 MSPS TxDAC DAC in a 28-lead TSSOP package supplied on a 500-unit reel. The primary differences are resolution (14-bit vs 10-bit) and package type (SOIC vs TSSOP).
Do the AD9764ARZ and AD9760ARU50RL7 have the same update rate?
Yes. Both devices are specified for a maximum update rate of 125 MSPS, making them suitable for comparable high-speed signal synthesis applications despite their different resolutions.
Are the AD9764ARZ and AD9760ARU50RL7 pin-compatible?
No. The AD9764ARZ uses a 28-lead SOIC package, while the AD9760ARU50RL7 uses a 28-lead TSSOP package. The package footprints and PCB land patterns differ, so they are not drop-in replacements for each other.
What is the resolution difference and how does it affect performance?
The AD9764ARZ provides 14-bit resolution, offering finer quantization and lower quantization noise than the 10-bit AD9760ARU50RL7. The higher resolution of the AD9764ARZ supports greater dynamic range and improved signal fidelity in demanding applications.
What does the "50RL7" suffix on the AD9760ARU50RL7 indicate?
The suffix indicates the device is supplied in tape-and-reel packaging with a 500-unit reel quantity, which is intended for automated high-volume assembly. The AD9764ARZ is supplied in tube or tray packaging depending on the ordering option.
Can the AD9764ARZ be used as a replacement for the AD9760ARU50RL7 in an existing design?
Not directly. Although both are 125 MSPS TxDAC devices, the AD9764ARZ is 14-bit versus 10-bit for the AD9760ARU50RL7, and the packages differ (SOIC vs TSSOP). A replacement requires PCB redesign and validation of the digital interface and analog performance against the target design.
Are both devices part of the same TxDAC family from Analog Devices?
Yes. Both the AD9764ARZ and AD9760ARU50RL7 are members of the Analog Devices TxDAC family of high-speed CMOS digital-to-analog converters, sharing the same transmit-DAC architecture and 125 MSPS update rate.
