Product details
Overview
ADAS3022BCPZ-RL7 from Analog Devices is a complete 16-bit, 1 MSPS, 8-channel successive approximation register (SAR) data acquisition system integrating an 8-channel multiplexer, programmable gain instrumentation amplifier (PGIA), on-chip 4.096 V reference, and precision ADC. It supports ±24.576 V differential input range, >500 MΩ input impedance, and operates from −40°C to +85°C for industrial monitoring applications.
For engineers reviewing the ADAS3022BCPZ-RL7 datasheet, ADAS3022BCPZ-RL7 pinout, ADAS3022BCPZ-RL7 application, or ADAS3022BCPZ-RL7 equivalent, this page delivers verified specifications, LFCSP-40 pin mapping, real-world use cases in power line monitoring and ATE, and two validated alternative parts with documented functional and interface differences.
Technical Context
The ADAS3022BCPZ-RL7 implements a fully integrated SAR-based architecture with no pipeline delay, enabling immediate result availability after conversion. Its PGIA offers user-programmable gains (0.16 to 6.4), supporting eight single-ended or four fully differential inputs referenced to COM, with high common-mode rejection (>100 dB at 2 kHz).
It features dual-domain power supplies: high-voltage analog rails (±15 V) for signal conditioning and low-voltage digital/analog rails (5 V AVDD/DVDD, 1.8–5 V VIO) for logic and reference buffering. The auxiliary ADC channel accepts ±4.096 V differential inputs and shares the same 16-bit resolution and twos-complement output format.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 16-bit SAR ADC with no missing codes - guarantees monotonicity and full-scale accuracy across all gain settings. |
| Throughput | 1 MSPS per channel in Warp Mode; 125 kSPS when scanning all 8 channels - enables real-time multichannel sampling without interleaving artifacts. |
| Differential Input Range | ±24.576 V max (at PGIA gain = 0.16) - supports direct connection to industrial ±10 V and ±15 V sensor outputs without external attenuation. |
| Input Impedance | >500 MΩ - eliminates loading errors on high-impedance sources such as thermocouples and piezoelectric sensors. |
| Common-Mode Rejection | >100 dB at 2 kHz - ensures accurate measurement of small differential signals riding on large common-mode voltages (e.g., motor current sensing). |
| Reference | Integrated 4.096 V buffered reference (±5 ppm/°C drift) - removes need for external precision reference and reduces BOM count and layout area. |
| Package | 6 mm × 6 mm LFCSP-40 with exposed paddle connected to VSSH - provides low thermal resistance (θJC = 0.28°C/W) for stable operation under continuous high-throughput loads. |
Pinout & Package
LFCSP-40 package (6 mm × 6 mm, 0.8 mm height) with exposed paddle electrically tied to VSSH for thermal and EMI performance. Pin 1 marked via top-side laser etch; recommended solder profile per JEDEC J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN0–IN7 | Analog Input Channels | Eight single-ended or four differential inputs; each supports >500 MΩ impedance and ±10.24 V common-mode range (up to ±12.228 V at PGIA gain = 0.16). |
| COM | Common Input Reference | Shared reference node for IN[7:0]; not used by AUX+/-; voltage limited to ±10.24 V except at lowest PGIA gain. |
| AUX+, AUX− | Auxiliary Differential Input | Dedicated 16-bit channel accepting ±4.096 V differential signals; bypasses PGIA and multiplexer for direct PulSAR ADC interface. |
| VDDH / VSSH | High-Voltage Analog Supplies | ±15 V nominal rails powering PGIA and multiplexer; require ≥2.5 V headroom from input pins (e.g., INx ≤ VDDH − 2.5 V). |
| AVDD / DVDD / VIO | Digital & Analog Core Supplies | 5 V analog/digital core (AVDD/DVDD); 1.8–5 V I/O interface supply (VIO) - enables interoperability with 1.8 V, 3.3 V, or 5 V controllers. |
| REF1 / REF2 / REFIN | Reference Interface | Supports internal 4.096 V reference or external reference; REFIN doubles as 2.5 V bandgap output or buffer input; REF1/REF2 must be shorted externally. |
| CS / SCK / DIN / SDO / BUSY / CNV | SPI-Compatible Digital Interface | 4-wire serial interface (no MISO/MOSI naming); SDO active during BUSY high; supports simultaneous read/write during quiet conversion phase (tDDCA). |
Key Features
| Feature | Design Value |
|---|---|
| No latency or pipeline delay | SAR architecture delivers conversion result immediately after BUSY deasserts - critical for closed-loop control and deterministic timing systems. |
| User-programmable input ranges | Eight differential (±1 V to ±10.24 V) and eight single-ended (0 V to 10 V) ranges selectable per channel via CFG register - eliminates external gain-switching circuitry. |
| Channel sequencer with individual gains | Hardware sequencer cycles through IN[7:0] with independent PGIA gain setting per channel - enables mixed-signal acquisition (e.g., temperature + voltage + current) in one frame. |
| On-chip 4.096 V reference and buffer | Low-drift (±5 ppm/°C), low-noise reference with integrated buffer - avoids external op-amp and decoupling complexity while maintaining <±0.6 LSB gain error. |
| High input common-mode rejection | >100 dB CMRR at 2 kHz - rejects noise from shared ground paths in PLC backplanes and motor drive cabinets without external guard traces. |
Applications
| Power Line Monitoring | Automated Test Equipment (ATE) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar multichannel SAR ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADAS3023BCPZ-RL7 | Same LFCSP-40 package and pinout; adds integrated temperature sensor with ±1.5°C accuracy and dedicated TEMP pin; identical PGIA, reference, and timing specs. | Required when board-level temperature compensation or ambient monitoring is needed alongside main acquisition; no change to analog signal chain design. | Select ADAS3023BCPZ-RL7 if on-die temperature sensing is required; otherwise ADAS3022BCPZ-RL7 minimizes cost and firmware complexity. |
| ADS8688IPWR | 8-channel, 16-bit, 1 MSPS SAR ADC with integrated PGA (gain 1–128), but uses single 5 V supply and lacks ±15 V high-voltage rails; no auxiliary ADC input. | Suitable for low-voltage industrial I/O modules where ±15 V supplies are unavailable; cannot replace ADAS3022BCPZ-RL7 in high-common-mode applications. | Choose ADS8688IPWR only for 5 V-only systems with lower common-mode requirements (<±5 V); ADAS3022BCPZ-RL7 remains necessary for ±10 V sensor interfaces. |
Compared with ADAS3022BCPZ-RL7, ADAS3023BCPZ-RL7 adds calibrated temperature sensing without altering signal path integrity, while ADS8688IPWR trades high-voltage capability for single-supply simplicity-making it incompatible for applications requiring >±5 V common-mode rejection or ±15 V rail support.

FAQ
What is the maximum differential input voltage supported by the ADAS3022BCPZ-RL7?
The ADAS3022BCPZ-RL7 supports a maximum differential input voltage of ±24.576 V when operating at PGIA gain = 0.16 with ±15 V supplies. This value scales inversely with PGIA gain (e.g., ±10.24 V at gain = 0.4), as defined in Table 2 of the Rev. D datasheet. Input voltage limits are enforced by the ±15 V supply headroom requirement: any input pin must remain within (VSSH + 2.5 V) and (VDDH − 2.5 V).
Does the ADAS3022BCPZ-RL7 require external reference components?
No, the ADAS3022BCPZ-RL7 includes a fully integrated, buffered 4.096 V reference with ±5 ppm/°C drift and 250 µA output drive capability. External decoupling (10 µF + 0.1 µF) on REF1/REF2 is mandatory, but no external reference IC or op-amp is needed. The device also supports external reference injection via REFIN, REF1, and REF2 pins if higher precision or different voltage is required.
How does the channel sequencer function in the ADAS3022BCPZ-RL7?
The ADAS3022BCPZ-RL7's hardware channel sequencer automatically cycles through IN[7:0] in ascending order upon consecutive CNV pulses, applying independently programmable PGIA gains per channel stored in the CFG register. Sequencing occurs without host CPU intervention, enabling deterministic multichannel acquisition frames at rates up to 125 kSPS for all eight inputs.
What is the purpose of the AUX+ and AUX− pins on the ADAS3022BCPZ-RL7?
AUX+ and AUX− provide a dedicated 16-bit auxiliary ADC input channel that bypasses the main multiplexer and PGIA, accepting ±4.096 V differential signals directly into the SAR core. This channel is intended for high-fidelity reference measurements, internal diagnostics (e.g., temperature sensor output), or secondary signal paths requiring zero gain error and minimal settling time.
Can the ADAS3022BCPZ-RL7 operate with a single 5 V supply?
No, the ADAS3022BCPZ-RL7 requires dual high-voltage analog supplies (VDDH = +15 V, VSSH = −15 V) to support its ±24.576 V input range and PGIA architecture. It also needs separate 5 V analog/digital supplies (AVDD, DVDD) and a flexible 1.8–5 V I/O supply (VIO). A single 5 V rail cannot power the high-voltage analog section and will prevent proper operation.
