Replacement verdict
Compatible functional replacement candidate
The AD9716BCPZ and AD9716BCPZRL7 are functionally identical dual 16-bit current-output DACs from Analog Devices, differing only in packaging format (tray vs. tape-and-reel). Both share the same die, electrical specifications, and LFCSP-40 footprint, making them fully interchangeable for design and production purposes; the choice between them is purely a matter of assembly and inventory handling preference.

Key electrical and mechanical differences between the two devices
| Parameter | AD9716BCPZ | AD9716BCPZRL7 | Why it matters |
|---|---|---|---|
| Resolution | 16 bit | 16 bit | Determines the quantization accuracy of the DAC output; identical resolution means equivalent signal fidelity. |
| Number of DAC Channels | 2 | 2 | Dual channels enable I/Q signal generation; matching channel count ensures functional interchangeability. |
| Update Rate (Max) | 125 MSPS | 125 MSPS | Sets the maximum sample rate for the DAC; identical rates mean the same bandwidth capability. |
| Output Type | Current - Unbuffered | Current - Unbuffered | Defines the interface to downstream analog stages; matching output type ensures circuit compatibility. |
| Supply Voltage | 1.8 V / 3.3 V | 1.8 V / 3.3 V | Determines power rail requirements; identical voltages allow the same board design to be reused. |
| Package / Case | 40-WFQFN Exposed Pad, CSP | 40-WFQFN Exposed Pad, CSP | Same footprint and thermal characteristics ensure drop-in PCB compatibility. |
| Operating Temperature Range | -40°C to 85°C | -40°C to 85°C | Confirms both parts meet the same environmental operating conditions for the target application. |
| Packaging / Delivery Form | Tray | Tape & Reel (7-inch reel) | Affects manufacturing handling and pick-and-place assembly; the reel version suits automated high-volume production while the tray suits prototyping. |
| Moisture Sensitivity Level (MSL) | MSL 3 (168 Hours) | MSL 3 (168 Hours) | Indicates floor-life handling requirements; identical MSL means the same storage and reflow precautions apply. |

Frequently asked questions
What is the difference between AD9716BCPZ and AD9716BCPZRL7?
The AD9716BCPZ and AD9716BCPZRL7 are the same dual 16-bit, 125 MSPS digital-to-analog converter (DAC) in a 40-lead LFCSP package. The difference is packaging format: AD9716BCPZ is supplied in trays, while AD9716BCPZRL7 is supplied in tape-and-reel packaging for automated assembly. Both share identical electrical specifications and die.
Are AD9716BCPZ and AD9716BCPZRL7 electrically and functionally interchangeable?
Yes. Both part numbers refer to the same AD9716 device in the same 40-lead LFCSP (CP-40-1) package with identical pinout, resolution (16-bit), sample rate (125 MSPS), and specifications. They differ only in shipping media (tray vs. tape-and-reel), so they are functionally interchangeable in a design.
What is the resolution and maximum sample rate of the AD9716?
The AD9716 is a dual 16-bit DAC with a maximum update rate of 125 MSPS. It is part of the AD9714/AD9715/AD9716 family, which offers 8-, 10-, and 16-bit resolutions respectively at up to 125 MSPS.
What package do AD9716BCPZ and AD9716BCPZRL7 use?
Both parts are offered in a 40-lead LFCSP (lead frame chip scale package), designated CP-40-1 by Analog Devices. The exposed pad must be soldered to the PCB ground plane for proper thermal and electrical performance.
What is the difference between the "Z" suffix and the "RL7" suffix in these part numbers?
The "Z" suffix indicates RoHS-compliant packaging per Analog Devices' nomenclature. The "RL7" suffix denotes tape-and-reel packaging (7-inch reel). AD9716BCPZ is the tray-packaged RoHS-compliant version, while AD9716BCPZRL7 is the tape-and-reel RoHS-compliant version of the same device.
What supply voltage does the AD9716 require?
The AD9716 operates from a single 1.8 V to 3.3 V analog and digital supply. The device includes an on-chip reference and integrated output termination resistors, and supports a flexible LVCMOS input interface.
Can AD9716BCPZRL7 be used as a drop-in replacement for AD9716BCPZ in an existing design?
Yes. Because both part numbers share the same die, package, pinout, and electrical specifications, AD9716BCPZRL7 can be used wherever AD9716BCPZ is specified. The only practical consideration is the assembly process: tape-and-reel is intended for automated pick-and-place, while trays are typically used for low-volume or manual assembly.
What are the key applications of the AD9716?
The AD9716 is used in applications requiring high dynamic range and dual-channel 16-bit DAC performance, including wireless infrastructure transmitters, cable modem termination systems, broadband communications, and instrumentation. Its 125 MSPS update rate and low noise make it suitable for IF and baseband signal synthesis.
