Replacement verdict
Compatible functional replacement candidate
The AD9176BBPZ and AD9173BBPZ are both dual-channel 16-bit high-speed DACs from the same Analog Devices AD917x family, sharing the same 144-ball BGA package and JESD204B interface architecture. The AD9176BBPZ offers a higher maximum DAC update rate and wider input data rate, making it a higher-performance superset of the AD9173BBPZ. While pin and footprint compatibility supports a functional replacement candidate, designers must validate the higher power envelope, clocking requirements, and JESD204B lane configuration against the target design before substitution.

Key electrical and mechanical differences between the two devices
| Parameter | AD9176BBPZ | AD9173BBPZ | Why it matters |
|---|---|---|---|
| Resolution (DAC Bits) | 16 | 16 | Bit depth determines the dynamic range and quantization noise floor of the DAC output; both parts share the same resolution. |
| Maximum DAC Update Rate | 12.6 GSPS | 12.6 GSPS | The DAC sample rate sets the achievable output bandwidth and Nyquist zone; identical rates mean similar wideband signal generation capability. |
| Number of DAC Channels | 2 | 2 | Dual DAC channels enable I/Q or multi-tone generation; matching channel count supports the same system architectures. |
| JESD204B Lane Rate (Max) | 15.4 Gbps | 15.4 Gbps | The serial lane rate determines the digital interface bandwidth needed from the FPGA/ASIC; identical rates allow the same host interface design. |
| On-Chip PLL | Yes | Yes | An integrated PLL simplifies clocking and reduces external components; both devices include this feature for flexible clock generation. |
| Digital Interpolation / NCO | Yes (dual NCO, interpolation filters) | Yes (dual NCO, interpolation filters) | Digital upconversion and interpolation allow flexible frequency placement and reduce host data rate requirements; both support this. |
| Package | 192-ball BGA (12 mm x 12 mm) | 192-ball BGA (12 mm x 12 mm) | Package and footprint compatibility affects PCB layout and assembly; identical packages ease board-level substitution. |
| Supply Voltage (Analog/Digital) | 0.95 V / 1.8 V | 0.95 V / 1.8 V | Supply rails determine power delivery design and compatibility with existing power trees; matching rails simplify replacement. |
| Operating Temperature Range | -40°C to +85°C | -40°C to +85°C | Industrial temperature range affects deployment in harsh environments; identical ranges support the same application conditions. |

Frequently asked questions
What are the key differences between the AD9176BBPZ and AD9173BBPZ?
The AD9176BBPZ is a dual-channel, 16-bit, 12 GSPS RF DAC with a maximum input data rate of 12 GSPS per channel and supports up to 6 GSPS of complex input data per channel. The AD9173BBPZ is a dual-channel, 16-bit, 12 GSPS RF DAC with a maximum input data rate of 6 GSPS per channel and supports up to 3 GSPS of complex input data per channel. Both are pin-compatible in the same 144-ball BGA package and share the same JESD204B interface, but the AD9176 offers higher digital datapath throughput and wider channelizer bandwidth.
Are the AD9176BBPZ and AD9173BBPZ pin-compatible and package-compatible?
Yes. Both devices are offered in the same 144-ball BGA package (BGA-144) with identical pin assignments, allowing a common PCB footprint. However, pin compatibility does not guarantee functional equivalence; the AD9176BBPZ supports higher JESD204B lane rates and wider digital signal processing bandwidth than the AD9173BBPZ, so firmware and clocking configurations must be validated for each device.
What is the maximum DAC update rate for each device?
Both the AD9176BBPZ and AD9173BBPZ have a maximum DAC update rate of 12 GSPS. The difference lies in the digital input data rate: the AD9176BBPZ supports up to 12 GSPS per channel (6 GSPS complex), while the AD9173BBPZ supports up to 6 GSPS per channel (3 GSPS complex).
Do both devices support the JESD204B interface?
Yes. Both the AD9176BBPZ and AD9173BBPZ include a JESD204B serial interface. The AD9176BBPZ supports JESD204B lane rates up to 15.5 Gbps, while the AD9173BBPZ supports lane rates up to 12.5 Gbps. The number of lanes and the link configuration must be set according to the specific device datasheet.
Can the AD9173BBPZ be used as a drop-in replacement for the AD9176BBPZ?
No, not as a direct drop-in replacement. Although the devices are pin-compatible, the AD9173BBPZ has lower maximum input data rates and JESD204B lane rates than the AD9176BBPZ. A design using the AD9176BBPZ at its full 12 GSPS input rate cannot be supported by the AD9173BBPZ. The system clocking, JESD204B link parameters, and digital datapath configuration must be revalidated against the AD9173BBPZ datasheet before substitution.
What digital signal processing features differ between the two devices?
Both devices include a dual-channel digital datapath with interpolation filters, a numerically controlled oscillator (NCO), and a complex digital up-converter. The AD9176BBPZ provides a wider channelizer bandwidth and higher maximum input data rate, enabling wider instantaneous bandwidth per channel. The AD9173BBPZ offers a reduced maximum input data rate and correspondingly narrower channelizer bandwidth. Exact filter coefficients and interpolation ratios must be taken from the respective datasheets.
What are the typical applications for each device?
Both the AD9176BBPZ and AD9173BBPZ are intended for wideband RF signal synthesis in applications such as wireless base stations, microwave point-to-point radios, satellite communications, and phased-array radar. The AD9176BBPZ is suited to applications requiring the highest input data rate and widest instantaneous bandwidth, while the AD9173BBPZ addresses applications with lower input data rate requirements where pin compatibility with the AD9176 family is beneficial.
