Replacement verdict
Compatible functional replacement candidate
The AD7683BRMZRL7 is a strong functional replacement candidate for the AD7683BRMZRL7 in most designs, sharing the same 16-bit SAR architecture, 100 kSPS throughput, and MSOP-8 footprint. Designers should validate the serial interface timing and reference configuration before committing to a drop-in substitution.

Key electrical and mechanical differences between the two devices
| Parameter | AD7680BRMZ | AD7683BRMZRL7 | Why it matters |
|---|---|---|---|
| Resolution | 16 bit | 16 bit | Both converters provide the same 16-bit resolution, so measurement precision is equivalent. |
| Sampling Rate | 100 kSPS | 100 kSPS | Identical maximum throughput allows the same signal bandwidth and timing budget in a design. |
| Number of Input Channels | 1 (single-ended) | 1 (single-ended) | Both are single-channel ADCs, so channel count and input topology are directly interchangeable. |
| Interface Type | SPI / QSPI / MICROWIRE / DSP compatible serial | SPI / QSPI / MICROWIRE / DSP compatible serial | Matching serial interfaces mean the same host controller and firmware can drive either part. |
| Supply Voltage | 2.7 V to 5.5 V | 2.7 V to 5.5 V | The same supply range supports identical power rail design and level compatibility. |
| Package | 8-lead MSOP | 8-lead MSOP | Identical package and pinout allow a drop-in footprint replacement on the PCB. |
| Operating Temperature Range | -40 °C to +85 °C | -40 °C to +85 °C | Same industrial temperature range ensures equivalent environmental robustness. |
| Power Consumption | Typically ~3.5 mW at 5 V, 100 kSPS | Typically ~3.5 mW at 5 V, 100 kSPS | Comparable power draw keeps thermal and energy budgets unchanged when substituting. |
| Reference | External reference | External reference | Both require an external reference, so the same reference circuit and accuracy can be reused. |

Frequently asked questions
What are the key differences between the AD7680BRMZ and AD7683BRMZRL7?
The AD7680BRMZ is a 16-bit, 100 kSPS PulSAR analog-to-digital converter, while the AD7683BRMZRL7 is a 16-bit, 100 kSPS PulSAR ADC with a different digital interface configuration. The AD7683BRMZRL7 is supplied in a 7-inch reel (RL7 suffix) for automated assembly, whereas the AD7680BRMZ is supplied in tube form. Both are offered in a 10-lead MSOP package and share the same core ADC architecture, but they differ in interface timing and packaging format.
Are the AD7680BRMZ and AD7683BRMZRL7 pin-compatible?
Both devices are housed in a 10-lead MSOP (RM) package. However, pin function assignments and digital interface timing differ between the two models, so designers must verify the pinout against the respective manufacturer datasheets before considering any board-level substitution.
What is the resolution and throughput of these ADCs?
Both the AD7680BRMZ and AD7683BRMZRL7 are 16-bit successive-approximation (SAR) ADCs with a maximum throughput of 100 kSPS, as specified in the Analog Devices datasheets for each part.
What is the difference between the BRMZ and BRMZRL7 suffixes?
The "BRMZ" suffix indicates a 10-lead MSOP package in a tube or tray shipping format, while "BRMZRL7" indicates the same package supplied on a 7-inch tape-and-reel for high-volume automated placement. The electrical grade and package body are the same; only the packaging and shipment format differ.
Can the AD7683BRMZRL7 be used as a drop-in replacement for the AD7680BRMZ?
Not without validation. Although both are 16-bit, 100 kSPS SAR ADCs in a 10-lead MSOP, their digital interface timing and control signal behavior differ. A drop-in replacement requires confirming pin functions, serial interface timing, and host controller compatibility against both datasheets.
What supply voltage and reference configuration do these ADCs require?
Both devices operate from a single 2.7 V to 5.25 V supply and use an external reference applied to the REF pin, as documented in the Analog Devices datasheets. The reference voltage sets the full-scale input range of the converter.
What serial interface do the AD7680BRMZ and AD7683BRMZRL7 use?
Both parts provide a serial digital output compatible with SPI/QSPI/MICROWIRE/DSP interface standards. The exact clock polarity, timing, and conversion-start behavior differ between the two models and must be checked in the respective datasheets.
Which applications are these 16-bit SAR ADCs suited for?
Both the AD7680BRMZ and AD7683BRMZRL7 are intended for precision data acquisition applications such as battery-powered instruments, medical instrumentation, process control, and portable measurement systems, where 16-bit resolution at 100 kSPS with low power consumption is required.
