Replacement verdict
Not a drop-in replacement
AD976ARZ and AD9760ARURL7 are not functionally interchangeable: they differ in resolution, sampling rate, and digital interface architecture, so substituting one for the other requires a full design review rather than a direct swap.

Key electrical and mechanical differences between the two devices
| Parameter | AD976ARZ | AD9760ARURL7 | Why it matters |
|---|---|---|---|
| Resolution | 16 bit | 10 bit | Resolution determines the number of discrete output levels; a 16-bit DAC offers far finer quantization than a 10-bit DAC, so they are not functionally interchangeable in precision applications. |
| Sampling Rate | 100 kSPS | 125 MSPS | The maximum update rate defines the signal bandwidth the DAC can synthesize; the two parts differ by orders of magnitude, suiting very different applications. |
| Architecture | Current-output R-2R (segmented) | Current-output CMOS DAC | The internal conversion architecture affects linearity, settling behavior, and output interface requirements, influencing whether one part can directly replace the other. |
| Output Type | Current (unipolar) | Current (differential) | Output configuration determines the external op-amp or transformer circuitry needed; differential current output requires different interfacing than a single-ended current output. |
| Supply Voltage | ±5 V (dual supply) | 3.0 V to 3.6 V (single supply) | Supply requirements dictate board-level power design; a dual ±5 V part cannot be dropped into a 3.3 V single-supply socket without redesign. |
| Package | 28-lead SOIC | 28-lead TSSOP | Package footprint and pinout must match for physical substitutability; different package types require different PCB land patterns. |
| Interface | Parallel | Parallel | Both use a parallel digital interface, but the bus width differs (16-bit vs 10-bit), so the host controller data path must be adapted. |
| Operating Temperature Range | -40 °C to +85 °C | -40 °C to +85 °C | Both cover the industrial temperature range, so thermal environment is not a differentiator between these two parts. |

Frequently asked questions
Are the AD976ARZ and AD9760ARURL7 functionally interchangeable?
No. The AD976ARZ is a 16-bit, 100 kSPS parallel-output ADC in a 28-lead SOIC package, while the AD9760ARURL7 is a 10-bit, 125 MSPS high-speed ADC in a 28-lead TSSOP package. They differ in resolution, sample rate, output interface, and package, so they are not direct substitutes.
What are the key resolution and sampling-rate differences between the two parts?
The AD976ARZ provides 16-bit resolution at up to 100 kSPS, whereas the AD9760ARURL7 provides 10-bit resolution at up to 125 MSPS. The AD9760ARURL7 is intended for high-speed signal conversion, while the AD976ARZ targets precision, lower-speed applications.
Do the AD976ARZ and AD9760ARURL7 use the same output interface?
No. The AD976ARZ provides a parallel digital output word for its 16-bit conversion result, while the AD9760ARURL7 provides a 10-bit parallel output at high speed. The bus widths and timing characteristics differ, so the receiving logic must be designed accordingly.
Are the packages of the AD976ARZ and AD9760ARURL7 compatible on a PCB?
No. The AD976ARZ is supplied in a 28-lead SOIC package, and the AD9760ARURL7 is supplied in a 28-lead TSSOP package. The package footprints and land patterns differ, so a board designed for one part cannot directly accept the other without layout changes.
Can the AD9760ARURL7 be used to replace an AD976ARZ in a precision measurement design?
No. The AD9760ARURL7 has 10-bit resolution versus 16-bit resolution for the AD976ARZ, so it cannot preserve the same measurement accuracy. A replacement would require revalidation of resolution, linearity, and system error budget against the manufacturer datasheets.
What are the typical application differences between the AD976ARZ and AD9760ARURL7?
The AD976ARZ is suited to precision data acquisition and instrumentation where 16-bit resolution at 100 kSPS is required. The AD9760ARURL7 is suited to high-speed signal processing and communications applications where 10-bit resolution at 125 MSPS is required. These application roles are not equivalent.
Do both parts share the same manufacturer and datasheet family?
Both are Analog Devices parts, but they belong to different converter families and have separate datasheets. Designers should consult the respective official Analog Devices datasheets for verified specifications before comparing or substituting them.
