Product details
Overview
ADAS3023BCPZ-RL7 from Analog Devices is a 16-bit, 8-channel simultaneous-sampling data acquisition system (DAS) integrating PGIA, SAR ADC, on-chip 4.096 V reference, and SPI-compatible digital interface. It delivers 125 kSPS throughput at 8 channels, ±20.48 V differential input range, >500 MΩ input impedance, and 95.0 dB common-mode rejection-enabling high-accuracy industrial voltage monitoring with minimal external circuitry.
For engineers reviewing the ADAS3023BCPZ-RL7 datasheet, ADAS3023BCPZ-RL7 pinout, ADAS3023BCPZ-RL7 application, or ADAS3023BCPZ-RL7 equivalent, this page provides verified specifications, validated pin functions, confirmed thermal and supply requirements, and real-world use context for multichannel precision measurement systems requiring simultaneous sampling and high common-mode immunity.
Technical Context
The ADAS3023BCPZ-RL7 implements a successive approximation register (SAR) architecture with no pipeline latency, enabling immediate result availability after conversion. Its integrated programmable gain instrumentation amplifier supports four differential input ranges (±20.48 V, ±10.24 V, ±5.12 V, ±2.56 V) via configuration register control, with factory calibration ensuring <±1 LSB integral linearity error across all gains.
It operates with dual high-voltage analog supplies (VDDH = +15 V, VSSH = −15 V), separate 5 V analog/digital supplies (AVDD/DVDD), and flexible 1.8 V–5 V I/O voltage (VIO). The device uses internal 2.5 V regulators (ACAP, DCAP, RCAP) decoupled with 10 µF + 0.1 µF capacitors, and features dedicated AGND, DGND, and RGND planes to maintain signal integrity in mixed-signal environments.
Key Specifications

| Throughput (8 ch) | 125 kSPS-sufficient for 50/60 Hz power quality analysis with oversampling and harmonic capture up to 5 kHz. |
| Reference Voltage | On-chip 4.096 V buffered reference with ±5 ppm/°C drift-provides stable scaling without external reference IC or trimming. |
Pinout & Package
ADAS3023BCPZ-RL7 is housed in a 40-lead LFCSP package (6 mm × 6 mm, exposed pad), rated for −40°C to +85°C operation. The exposed pad must be connected to VSSH for thermal and electrical performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN0–IN7 | Analog Input Channels | Eight high-impedance differential inputs referenced to COM-support simultaneous sampling without multiplexer-induced delay or crosstalk. |
| COM | Common Input Reference | Shared reference node for all INx channels; max voltage ±10.24 V-defines differential measurement point and sets common-mode boundary. |
| CS, DIN, SCK, SDO, BUSY/SDO2 | SPI-Compatible Digital Interface | 4-wire serial interface (1.8 V–5 V compatible) with dual-data-output capability-enables daisy-chaining or status-aware readout without additional GPIO. |
| CNV | Convert Trigger Input | Rising-edge–initiated conversion start-synchronizes sampling across all 8 channels with sub-nanosecond aperture delay (tAD = 2 ns). |
| VDDH / VSSH | High-Voltage Analog Supplies | +15 V / −15 V rails powering PGIA and track-and-hold-enable wide input range while isolating sensitive analog core from digital noise. |
| REF1 / REF2 | Reference Input/Output | Configurable reference pins supporting internal 4.096 V or external reference-allow calibration traceability or enhanced stability with external low-drift source. |
Key Features
| Feature | Design Value |
|---|---|
| No latency/pipeline delay | SAR architecture delivers conversion results immediately post-CNV rising edge-enables deterministic timing for closed-loop control and real-time triggering. |
| User-programmable input ranges | Four differential ranges (±2.56 V to ±20.48 V) selected via CFG register-eliminates need for external gain-switching circuitry or manual range selection hardware. |
| Integrated PGIA + reference + buffer | Single-chip solution replaces discrete instrumentation amp, reference IC, and ADC-reduces BOM count, PCB area, and calibration complexity. |
| High input common-mode rejection | 95.0 dB CMRR maintained across all channels and gains-ensures accurate differential measurements in presence of ground loops or EMI. |
| Factory calibrated | Guaranteed INL ≤ ±1 LSB and DNL ≤ ±0.5 LSB at all PGIA gains-removes need for system-level linearity correction or look-up table compensation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar multichannel simultaneous-sampling data acquisition applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADAS3022BCPZ-RL7 | 8-channel, 16-bit, but limited to 100 kSPS at 8 channels and ±10.24 V max input range; lacks internal 4.096 V reference buffer. | Suitable for lower-throughput or lower-voltage industrial monitoring where reference buffering is handled externally. | Select when cost sensitivity outweighs need for highest speed or widest input range; verify external reference stability meets system accuracy goals. |
| LTC2358ILX-16#PBF | 8-channel, 16-bit, 1 MSPS per channel (multiplexed), not simultaneous; requires external PGA and reference; SPI-only interface. | Better for high-speed single-channel burst acquisition, not phase-coherent multichannel capture. | Choose only if application prioritizes per-channel speed over simultaneity; expect added design effort for gain matching and timing alignment. |
Compared with ADAS3023BCPZ-RL7, ADAS3022BCPZ-RL7 trades throughput and reference integration for lower cost, while LTC2358ILX-16#PBF offers higher per-channel speed at the expense of simultaneity, external signal conditioning, and increased layout complexity.

FAQ
What is the maximum differential input voltage supported by the ADAS3023BCPZ-RL7?
The ADAS3023BCPZ-RL7 supports a maximum differential input voltage of ±20.48 V when operated with ±15 V analog supplies (VDDH = +15 V, VSSH = −15 V). This range is achieved using PGIA gain = 0.2 and the internal 4.096 V reference. Input voltage limits are strictly defined by the absolute maximum ratings: INx to COM must remain within VSSH + 2.5 V to VDDH − 2.5 V.
Does the ADAS3023BCPZ-RL7 require external calibration for production use?
No, the ADAS3023BCPZ-RL7 is factory calibrated and guarantees integral linearity error ≤ ±1 LSB and differential linearity error ≤ ±0.5 LSB across all PGIA gains and temperature range (−40°C to +85°C). System-level calibration is optional and only needed for applications demanding sub-LSB accuracy beyond datasheet specifications.
How does the ADAS3023BCPZ-RL7 handle power-down mode, and what is the wake-up sequence?
Asserting a low-to-high transition on the PD pin places the ADAS3023BCPZ-RL7 into power-down mode, reducing current draw to 10 µA. After releasing PD, the device requires 100 ms for the internal reference to stabilize, followed by one dummy conversion before valid data is available. The RESET pin remains low for 100 ns after PD release, ensuring clean initialization.
Can the ADAS3023BCPZ-RL7 operate with a 3.3 V digital interface supply (VIO)?
Yes, the ADAS3023BCPZ-RL7 supports VIO from 1.8 V to AVDD (5 V), including 3.3 V logic levels. At VIO = 3.3 V, the digital inputs accept VIH ≥ 2.97 V and VIL ≤ 0.33 V, while outputs drive VOH ≥ 3.0 V and VOL ≤ 0.4 V under 500 µA load-ensuring reliable interfacing with standard 3.3 V microcontrollers and FPGAs.
What is the purpose of the BUSY/SDO2 pin on the ADAS3023BCPZ-RL7?
The BUSY/SDO2 pin serves dual function: when CS is high, it outputs a busy signal indicating active conversion; when CS is pulled low after end-of-conversion (EOC), it becomes a second serial data output (SDO2) synchronized to SCK falling edges. This enables status polling or concurrent readout of conversion results and configuration registers without interrupt overhead.
