AD7983BCPZ-RL 概要
An SAR ADC is a precision data converter that uses an iterative binary-search algorithm with an internal capacitive DAC to digitize an analog input one bit per clock cycle. SAR ADCs deliver deterministic latency, no pipeline delay, and excellent DC accuracy, making them the preferred topology for multiplexed data-acquisition systems, precision instrumentation, and industrial control loops where deterministic per-sample timing and low noise are mandatory.
Key specifications include 16-bit resolution with no missing codes, ±0.6 LSB typical ( ±1.0 LSB maximum ) INL, throughput of 1.33 MSPS, and a versatile serial interface that can be wired to 1.8 V to 5 V digital logic. The analog input is sampled differentially between IN+ and IN-, with the full-scale range set by an external REF voltage from 2.375 V to 2.625 V. CNV rising-edge triggering initiates conversion, and the on-chip oscillator eliminates the need for an external clock source.
The architecture pairs a low-power, high-speed sampling front end with an internal precision reference buffer and a compact serial output that minimizes GPIO usage on the host MCU or DSP. Power-down between conversions reduces average dissipation in low-duty-cycle applications, and the -40 °C to +85 °C industrial operating range supports factory-floor deployment.
Typical applications include portable and battery-powered instrumentation, process-control analog front ends, data-acquisition modules, and precision sensor signal chains. The wide logic compatibility and small footprint also suit medical monitoring and industrial IoT edge nodes.
When designing with the AD7983BCPZ-RL, bypass VDD and REF with 10 µF and 100 nF ceramic capacitors placed within 5 mm of the package, and keep the analog input traces short and guarded. The exposed pad must be soldered to the ground plane for thermal dissipation and low-impedance return.

Portable Battery-Powered Instrumentation
The AD7983BCPZ-RL's 10.5 mW dissipation at 1.33 MSPS and 2.5 V single-supply operation make it ideal for portable, battery-powered instrumentation such as handheld oscilloscope front ends, field data loggers, and wireless sensor readouts. PulSAR SAR architecture provides zero pipeline delay and deterministic per-sample latency, which simplifies interrupt-driven firmware on the host MCU. Power-down between conversions reduces average current in low-duty-cycle measurements; combined with the 3x3 mm LFCSP footprint, the ADC fits inside handheld enclosures while leaving PCB area for the analog front end, MCU, and battery management. The 16-bit no-missing-codes performance also meets the dynamic-range requirements of strain-gauge, thermocouple, and bridge-sensor signal chains typical in portable test gear.

Industrial Process Control and PLC Analog Input Modules
The AD7983BCPZ-RL suits industrial process-control analog input modules and PLC analog front ends where deterministic latency, ±0.6 LSB typical INL, and 1.33 MSPS throughput enable accurate 4-20 mA loop, RTD, and thermocouple digitization. The -40 °C to +85 °C industrial temperature range and single 2.5 V supply align with 24 V field-bus architectures stepped down by isolated DC-DC converters. The differential IN+/IN- input pair with an external REF up to 2.625 V allows direct connection to instrumentation-amplifier outputs, simplifying the front-end chain. Pin-for-pin compatibility with the 18-bit AD7982 supports a single PCB layout that scales between precision and high-speed product SKUs.
おすすめ
Multiplexed Data Acquisition Systems
The AD7983BCPZ-RL delivers 1.33 MSPS throughput with no conversion pipeline delay, making it well-suited for multiplexed data-acquisition (DAQ) systems scanning multi-channel sensor arrays. SAR architecture guarantees deterministic per-channel latency, which is critical when the host controller must correlate samples with channel IDs for safety or control loops. The compact 10-pin LFCSP-WD footprint frees board space for external multiplexers (such as ADG708/ADG726) and per-channel signal conditioning. The 16-bit no-missing-codes performance and ±1.0 LSB maximum INL ensure channel-to-channel gain matching across the multiplexer, while the wide 1.8 V to 5 V logic interface simplifies digital isolation barrier design in industrial DAQ modules.
おすすめ
Precision Sensor Signal Chains
The AD7983BCPZ-RL's 16-bit resolution, ±0.6 LSB typical INL, and differential input pair make it ideal for precision sensor signal chains digitizing outputs from load cells, pressure transducers, RTDs, and bridge-type flow meters. SAR architecture's inherent zero-latency behavior eliminates filter-induced group delay, allowing real-time closed-loop control based on the digitized sensor value. An external 2.5 V reference (such as ADR441 or ADR4525) sets the absolute accuracy of the conversion, while the 10.5 mW power budget keeps thermal gradients low for strain-gauge stability. The small 3x3 mm LFCSP package lets the ADC sit directly behind the sensor's instrumentation amplifier (e.g., AD8421) on the analog island.
おすすめ
Medical Monitoring and Diagnostic Equipment
The AD7983BCPZ-RL supports medical monitoring and diagnostic equipment such as portable patient monitors, infusion-pump controllers, and laboratory analyzers requiring precise, low-power analog-to-digital conversion. SAR architecture's deterministic latency and zero pipeline delay enable real-time waveform capture (ECG, pulse oximetry, respiration) with sample-accurate timestamping, which is critical for diagnostic algorithms. The 2.5 V single-supply operation simplifies battery-powered designs and aligns with medical-isolation barrier constraints. The 1.33 MSPS throughput is more than adequate for vital-signs bandwidths while maintaining 16-bit no-missing-codes performance for accurate amplitude measurement. The 10-pin LFCSP-WD 3x3 mm footprint also supports compact, single-board medical device form factors.
おすすめ
Industrial IoT Edge Sensor Nodes
The AD7983BCPZ-RL's 10.5 mW dissipation, 2.5 V single-supply operation, and small LFCSP-WD footprint make it a strong fit for industrial IoT edge sensor nodes digitizing analog sensors before wireless transmission. SAR architecture's deterministic per-sample latency simplifies the deterministic-timing guarantees required by industrial protocols such as IO-Link Wireless and WirelessHART. The 1.33 MSPS throughput allows oversampling and averaging for noise reduction in harsh EMI environments. Pin-for-pin compatibility with the 18-bit AD7982 lets a single PCB platform serve entry-level (16-bit) and high-precision (18-bit) SKUs. The wide 1.8 V to 5 V digital logic compatibility lets the ADC interface directly to low-power IoT MCUs and wireless SoCs without level shifters.
おすすめ
Power Quality and Energy Metering Front Ends
The AD7983BCPZ-RL's 1.33 MSPS throughput and 16-bit resolution deliver adequate dynamic range for power-quality and energy-metering front ends that digitize current-transformer (CT) and voltage-divider outputs at the utility meter or sub-meter level. SAR architecture's zero-latency conversion ensures phase-accurate sampling for harmonic analysis and reactive-power computation. The differential IN+/IN- input pair simplifies direct connection to CT secondaries with proper burden-resistor scaling, while the external REF up to 2.625 V accommodates common-mode voltage swings from the CT. The 10.5 mW typical dissipation keeps the meter's thermal budget within IEC 62053 accuracy class limits. The compact LFCSP package also fits inside the dense meter baseboard alongside metrology MCUs and isolation barriers.

設計ノート
Place the 10 µF and 100 nF VDD bypass capacitor pair within 5 mm of the VDD pin and the equivalent REF decoupling pair within 5 mm of the REF pin. Use wide, short analog input traces on IN+ and IN- routed as a matched differential pair, and surround them with a continuous analog ground pour on an inner layer. The exposed pad (EP) MUST be soldered to the PCB ground plane using multiple thermal vias (at least 9 in a 3x3 pattern) to provide low-impedance return and thermal dissipation. Reference the Analog Devices AD7983 datasheet layout guidelines for the recommended evaluation-board stack-up.
Drive CNV with a clean, low-jitter CMOS signal - any ringing or slow edges couple directly into the sampled input. Add a small RC snubber (e.g., 33 Ω in series with 47 pF to GND) on CNV if the source is a long cable or noisy MCU GPIO. Keep SCK below 50 MHz as recommended in the Analog Devices datasheet; faster clocks degrade SNR due to aperture jitter. Maintain a clean REF voltage using a low-noise reference such as ADR441 or ADR4525 with its own local decoupling to avoid reference-induced linearity drift.
Do NOT omit the exposed-pad solder connection - the part's thermal and electrical ground depends on it. Do NOT exceed the 2.625 V maximum on VDD or REF; the part has no internal over-voltage protection. Do NOT leave unused digital inputs (SDI for single-device mode) floating - tie SDI to GND. Do NOT use a noisy switching supply to power the ADC; route the 2.5 V through a low-noise LDO such as ADP7102 to avoid coupling switching noise into the conversion. Per the datasheet, perform a power-on reset by holding CNV high before the first conversion to ensure the on-chip oscillator stabilizes.
