Product details
Overview
AD7980SRMZ-EP-RL7 from Analog Devices is a 16-bit, 1 MSPS successive approximation register (SAR) analog-to-digital converter (ADC) in a 10-lead MSOP package, operating over −55°C to +125°C. It features ±1.5 LSB max integral nonlinearity, 91 dB SINAD at 10 kHz, and pseudo-differential input range of 0 V to VREF (2.4 V–5.1 V), enabling high-precision data acquisition in harsh-environment instrumentation.
For engineers reviewing the AD7980SRMZ-EP-RL7 datasheet, AD7980SRMZ-EP-RL7 pinout, AD7980SRMZ-EP-RL7 application, or AD7980SRMZ-EP-RL7 equivalent, key selection criteria include military-grade temperature operation, SPI/QSPI/MICROWIRE-compatible serial interface with daisy-chain capability, low 7 mW total power at full throughput, and no pipeline delay for deterministic timing in real-time control loops.
Technical Context
The AD7980SRMZ-EP-RL7 implements a single-supply SAR architecture with separate VDD (2.375 V–2.625 V) and VIO (1.8 V–5.5 V) rails, supporting 1.8 V/2.5 V/3 V/5 V logic compatibility. Its conversion is initiated on the CNV rising edge, sampling IN+ relative to IN− with no latency between sample and result availability.
It uses an external reference (REF) decoupled with a 10 µF capacitor, supports both CS and chain interface modes selected via SDI level at CNV edge, and delivers 16-bit straight-binary output synchronized to SCK with 710 ns maximum conversion time and 290 ns acquisition time.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 16-bit with no missing codes - guarantees monotonicity and full code coverage across full-scale range. |
| Throughput | 1 MSPS maximum - enables real-time sampling of signals up to ~400 kHz Nyquist bandwidth. |
| INL | ±1.5 LSB maximum - ensures <±0.023% full-scale error for precision measurement systems. |
| SINAD | 91 dB at 10 kHz (5 V REF) - corresponds to ~15.1 effective bits for clean signal capture. |
| Power Dissipation | 7 mW total at 1 MSPS - allows battery-powered or thermally constrained deployments without active cooling. |
| Analog Input Range | 0 V to VREF (2.4 V–5.1 V) - supports flexible scaling with external references for optimal dynamic range utilization. |
| Operating Temperature | −55°C to +125°C - qualified for defense, aerospace, and downhole industrial applications per AQEC standards. |
Pinout & Package
The AD7980SRMZ-EP-RL7 is housed in a 10-lead MSOP (RM-10) package compliant with JEDEC MO-187-BA, with 0.5 mm pitch and exposed pad not connected internally.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| REF | Analog Reference Input | External reference voltage (2.4 V–5.1 V); must be decoupled with 10 µF capacitor for stable ADC accuracy. |
| VDD | Analog Power Supply | 2.375 V–2.625 V supply powering core ADC circuitry; separate from digital I/O rail. |
| IN+ | Analog Input Positive | Pseudo-differential input; sampled relative to IN−, range = 0 V to VREF. |
| IN− | Analog Input Ground Sense | Reference point for IN+; connects to analog ground plane or remote sense node. |
| GND | Power Ground | Common return for VDD, REF, and analog section; requires low-impedance connection. |
| CNV | Convert Control Input | Rising edge initiates conversion and selects interface mode (CS or chain); also enables busy indicator. |
| SDO | Serial Data Output | 16-bit straight-binary output; tri-state when CNV or SDI is high in CS mode. |
| SCK | Serial Clock Input | Drives data shift-out; timing varies with VIO level (e.g., min 10.5 ns period at VIO > 4.5 V). |
| SDI | Serial Data Input | Selects interface mode at CNV edge; in chain mode, passes prior ADC's data with 16-cycle delay. |
| VIO | Digital I/O Power | Supplies logic interface (1.8 V–5.5 V); isolates digital noise from analog section. |
Key Features
| Feature | Design Value |
|---|---|
| No pipeline delay | Conversion result available immediately after completion - eliminates latency uncertainty in closed-loop control. |
| Daisy-chain capability | Multiple AD7980SRMZ-EP-RL7 devices share one SDO line using SDI as data-in - reduces PCB routing and host GPIO count. |
| Low power scaling | 70 µW at 10 kSPS - enables ultra-low-duty-cycle wake-up sampling in energy-harvesting sensor nodes. |
| Military-grade qualification | AQEC-compliant with controlled manufacturing baseline, single fab/assembly site, and enhanced change notification - ensures long-term supply stability. |
| Flexible reference interface | REF independent of VDD and supports 2.4 V–5.1 V range - permits optimization of resolution vs. input signal swing. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-precision, high-speed SAR ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD7982BRMZ-RL7 | 18-bit resolution, same 1 MSPS rate, but higher 12 mW power and wider −40°C to +85°C temp range. | Used where ultimate resolution outweighs power/temperature constraints, e.g., lab-grade bench instruments. | Choose AD7982BRMZ-RL7 only if 18-bit depth is required and extended temperature is not needed. |
| AD7686BRMZ-RL7 | 16-bit, 500 kSPS max, lower 3.5 mW power, same MSOP package and SPI interface, but −40°C to +85°C rating. | Preferred for commercial industrial controllers where cost and power efficiency dominate over extreme environment operation. | Choose AD7686BRMZ-RL7 when throughput ≤500 kSPS suffices and military temperature range is unnecessary. |
Compared with AD7980SRMZ-EP-RL7, AD7982BRMZ-RL7 trades higher resolution and power for reduced temperature capability, while AD7686BRMZ-RL7 sacrifices speed and ruggedness for lower cost and power-making AD7980SRMZ-EP-RL7 the sole option meeting 1 MSPS, 16-bit, and −55°C to +125°C simultaneously.

FAQ
What is the maximum operating temperature range for the AD7980SRMZ-EP-RL7?
The AD7980SRMZ-EP-RL7 is specified for continuous operation from −55°C to +125°C, validated per AQEC standards for defense and aerospace applications. This extended range is achieved through controlled manufacturing baseline, single fabrication and assembly site, and enhanced product change notification protocols - all documented in the AD7980-EP Rev. A datasheet.
Does the AD7980SRMZ-EP-RL7 support daisy-chaining with other ADCs?
Yes, the AD7980SRMZ-EP-RL7 supports daisy-chaining via its SDI input and SDO output in chain mode. When SDI is low at the CNV rising edge, the device enters chain mode: incoming data on SDI is delayed by 16 SCK cycles and appears on SDO, allowing multiple AD7980SRMZ-EP-RL7 units to share a single serial bus without additional logic.
What reference voltage range is supported by the AD7980SRMZ-EP-RL7?
The AD7980SRMZ-EP-RL7 accepts an external reference voltage (REF) from 2.4 V to 5.1 V, independent of VDD. The analog input range is 0 V to VREF, and REF must be decoupled with a 10 µF capacitor at the pin. Performance metrics such as SINAD and INL are characterized across this full range, including 91 dB SINAD at 5 V REF and 86.5 dB at 2.5 V REF.
Is the AD7980SRMZ-EP-RL7 pin-compatible with other PulSAR® ADCs?
Yes, the AD7980SRMZ-EP-RL7 is pin-for-pin compatible with the standard AD7980 and shares the same 10-lead MSOP footprint and pinout as listed in Table 6 of the AD7980-EP datasheet. This compatibility extends to electrical interface behavior, timing, and register mapping - enabling drop-in replacement in existing designs requiring enhanced product qualifications.
What logic voltage levels does the AD7980SRMZ-EP-RL7 support on its digital interface?
The AD7980SRMZ-EP-RL7 supports 1.8 V, 2.5 V, 3 V, and 5 V logic levels via its dedicated VIO supply (1.8 V–5.5 V). Digital input thresholds scale with VIO - for example, VIH = 0.7 × VIO when VIO > 3 V - and output drive strength is specified for ISINK/ISOURCE = ±500 µA, ensuring robust interoperability with diverse host processors and FPGAs.
