Product details
Overview
AD7366BRUZ-500RL7 from Analog Devices is a dual-channel, simultaneous-sampling, 12-bit SAR ADC with true bipolar ±10 V/±5 V/0 V–10 V input ranges, 1 MSPS throughput, and integrated 2.5 V ±0.2% reference. It operates from ±16.5 V analog supplies and 4.75–5.25 V digital rails, delivering 72 dB SNR at 50 kHz for precision industrial data acquisition systems.
For engineers reviewing the AD7366BRUZ-500RL7 datasheet, AD7366BRUZ-500RL7 pinout, AD7366BRUZ-500RL7 application, or AD7366BRUZ-500RL7 equivalent, key selection criteria include simultaneous dual-channel sampling timing, iCMOS® high-voltage analog input capability, SPI/QSPI-compatible serial interface latency under 1 μs, and channel-to-channel isolation of −90 dB.
Technical Context
The AD7366BRUZ-500RL7 integrates two independent 12-bit SAR ADC cores, each with a 2-channel multiplexer and track-and-hold amplifier, enabling true simultaneous sampling of VA1/VA2 and VB1/VB2. Its iCMOS® process supports ±16.5 V analog supply rails while maintaining low power consumption (5.65 mA operational, 3 µA shutdown).
Conversion is initiated by CNVST falling edge; BUSY asserts high until conversion completes in 610 ns, after which 12-bit results appear MSB-first on DOUTA and DOUTB within one SCLK cycle. The device accepts programmable input ranges via RANGE0/RANGE1 pins and selects internal or external reference via REFSEL.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 12-bit, guaranteed no missing codes - ensures monotonic transfer function for closed-loop control feedback. |
| Throughput Rate | 1 MSPS - supports real-time monitoring of fast transients in motor phase current or vibration sensing. |
| SNR @ 50 kHz | 72 dB typical - enables 11.6 effective bits for high-fidelity signal reconstruction in test equipment. |
| Analog Input Ranges | ±10 V, ±5 V, 0 V to 10 V - configurable per application without external level-shifting circuitry. |
| Channel Isolation | −90 dB - prevents crosstalk between simultaneously sampled channels in multi-sensor systems. |
| Reference Accuracy | 2.5 V ±0.2% - eliminates need for external precision reference in cost-sensitive PLC I/O modules. |
| Supply Voltages | VDD = +11.5 to +16.5 V, VSS = −16.5 to −11.5 V, AVCC/DVCC = 4.75–5.25 V - supports direct connection to industrial ±15 V rails. |
Pinout & Package
AD7366BRUZ-500RL7 is housed in a 24-lead TSSOP package (4.4 mm × 7.8 mm, 0.65 mm pitch) with exposed pad for thermal management. Pin layout follows standard iCMOS® mixed-signal partitioning: analog inputs (VA1, VA2, VB1, VB2), dual serial outputs (DOUTA, DOUTB), and segregated AGND/DGND planes.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| DOUTA / DOUTB | Serial Data Output (A/B) | Simultaneous 12-bit MSB-first data streams; each pin delivers result from its respective ADC core with no interleave delay. |
| CNVST | Conversion Start | Falling-edge triggered; initiates track-to-hold and conversion; low hold duration determines auto-power-down entry. |
| BUSY | Conversion Status Flag | High during conversion; falls 610 ns after CNVST edge - enables precise timing of read cycles in deterministic firmware. |
| RANGE0 / RANGE1 | Analog Input Range Select | Logic inputs setting ±10 V, ±5 V, or 0–10 V range; no external resistors required for range reconfiguration. |
| REFSEL | Reference Source Control | High = internal 2.5 V reference enabled; low = external reference applied to DCAPA/DCAPB pins. |
| DCAPA / DCAPB | Reference Decoupling Terminals | Accept 680 nF capacitors; also serve as buffered 2.5 V reference outputs when REFSEL = high. |
| VDD / VSS | Analog Power Supplies | +11.5 to +16.5 V and −16.5 to −11.5 V rails - enable true bipolar ±12 V input with external 3 V reference. |
| AGND / DGND | Analog & Digital Grounds | Physically separate pins; must be tied at single point with ≤0.3 V transient difference to maintain PSRR > 80 dB. |
Key Features
| Feature | Design Value |
|---|---|
| True bipolar input support | Accepts ±10 V, ±5 V, and 0–10 V ranges without external op-amp level shifting or clamping diodes. |
| Simultaneous dual-channel sampling | Two independent ADCs sample VA1/VA2 and VB1/VB2 at identical timestamps - critical for phase-sensitive measurements. |
| iCMOS® high-voltage process | Enables ±16.5 V analog supplies while achieving 8.3 mA typical operating current - reduces thermal load in dense PCB layouts. |
| SPI/QSPI/MICROWIRE compatibility | Single SCLK domain drives both DOUTA and DOUTB; 12-bit reads complete in <1 μs - simplifies FPGA interface logic. |
| On-chip 2.5 V reference (±0.2%) | Eliminates external reference IC and trimming components; DCAPA/DCAPB pins provide buffered output for system-wide use. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel SAR ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD7366BRUZ | Same die, 500-piece tape-and-reel vs. 500-RL7 reel; identical electrical specs and pinout. | No functional difference; differs only in packaging format and minimum order quantity. | Select AD7366BRUZ-500RL7 for automated SMT placement requiring 500-unit reels. |
| AD7367BRUZ-500RL7 | 14-bit resolution, 76 dB SNR, 680 ns conversion time - higher precision but lower speed than AD7366BRUZ-500RL7. | Better suited for high-resolution vibration analysis where 12-bit quantization noise is unacceptable. | Choose AD7367BRUZ-500RL7 when ENOB > 12.3 bits is required; accept 100 ns longer conversion latency. |
Compared with AD7366BRUZ-500RL7, AD7366BRUZ offers identical performance in a different reel configuration, while AD7367BRUZ-500RL7 trades 2-bit resolution gain for 70 ns slower conversion - making AD7366BRUZ-500RL7 optimal for cost-constrained, latency-sensitive 12-bit industrial acquisition.

FAQ
What input voltage ranges does the AD7366BRUZ-500RL7 support?
The AD7366BRUZ-500RL7 supports ±10 V, ±5 V, and 0 V to 10 V analog input ranges, selected via RANGE0 and RANGE1 logic inputs. With a 3 V external reference applied to DCAPA/DCAPB, it accepts true bipolar ±12 V inputs - requiring minimum ±12 V on VDD/VSS supplies. All ranges operate without external level-shifting circuitry.
How does the AD7366BRUZ-500RL7 achieve simultaneous sampling across two channels?
The AD7366BRUZ-500RL7 contains two independent SAR ADC cores, each with its own track-and-hold amplifier and 2-channel multiplexer. A single CNVST falling edge triggers both T/H circuits to hold simultaneously, initiating parallel conversions. Results appear on DOUTA and DOUTB within 610 ns, ensuring timestamp coherence for phase-critical measurements.
Can the AD7366BRUZ-500RL7 use an external reference, and how is it configured?
Yes - tie REFSEL to DGND to disable the internal 2.5 V reference and apply an external 2.5–3.0 V reference to DCAPA and/or DCAPB pins. When REFSEL = high, the internal reference activates and DCAPA/DCAPB require 680 nF decoupling capacitors. External reference mode enables ±12 V input operation with 3 V reference and improves system-level accuracy traceability.
What is the power consumption profile of the AD7366BRUZ-500RL7 in normal and shutdown modes?
In normal operational mode at 1 MSPS, AD7366BRUZ-500RL7 draws 5.65 mA from AVCC/DVCC, 2.0 mA from VDD, and 1.6 mA from VSS - totaling ~89 mW. In shutdown mode, current drops to 0.3 µA on AVCC/DVCC, 1 µA on VDD/VSS - reducing power to ~48.75 µW. This enables rapid wake-up (<70 µs) for duty-cycled sensor nodes.
Is the AD7366BRUZ-500RL7 pin-compatible with other devices in the AD7366/AD7367 family?
Yes - all AD7366 and AD7367 variants share identical 24-lead TSSOP pinouts, including AD7366BRUZ-500RL7, AD7366BRUZ, AD7367BRUZ-500RL7, and AD7367BRUZ. Signal names, power domains, ground assignments, and timing interfaces are fully aligned, allowing drop-in replacement within the same resolution grade (12-bit or 14-bit) when board layout permits.
