Product details
Overview
ADAS3022BSTZ from Analog Devices is a complete 16-bit, 1 MSPS successive approximation register (SAR) data acquisition system integrating an 8-channel low-leakage multiplexer, programmable gain instrumentation amplifier (PGIA), on-chip 4.096 V reference, and precision ADC. It supports ±24.576 V differential input range with >500 MΩ input impedance and >100 dB common-mode rejection, enabling direct high-voltage sensor interfacing in industrial power monitoring systems.
For engineers reviewing the ADAS3022BSTZ datasheet, ADAS3022BSTZ pinout, ADAS3022BSTZ application, or ADAS3022BSTZ equivalent, this page delivers verified technical context, real-world timing behavior, confirmed package mapping to LFCSP-40, validated pin functions per Analog Devices Rev. D documentation, and two rigorously cross-checked alternative parts for multichannel industrial DAQ designs.
Technical Context
The ADAS3022BSTZ implements a fully integrated SAR-based architecture with no pipeline delay-conversion results are available immediately after BUSY goes low. Its PGIA stage provides user-selectable gains (0.16 to 6.4) and supports eight single-ended or four fully differential inputs, with input ranges configurable from ±1 V to ±10.24 V using internal reference.
It features dual-domain power supplies: high-voltage analog rails (±15 V) for signal conditioning and 5 V/1.8–5 V digital rails for interface and logic. The device includes dedicated analog/digital/reference ground pins (AGND, DGND, RGND), three internal LDO outputs (ACAP, DCAP, RCAP), and auxiliary ADC inputs (AUX+/AUX−) for secondary measurements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 16-bit-guarantees no missing codes across full operating range for precision measurement integrity. |
| Throughput | 1 MSPS (single channel)-enables real-time sampling of fast transients in power line monitoring. |
| Differential Input Range | ±24.576 V max-supports direct connection to ±15 V supply-referenced sensors without external level shifting. |
| Input Impedance | >500 MΩ-minimizes loading error on high-impedance sources like thermocouples or piezoelectric sensors. |
| Common-Mode Rejection | >100 dB at 2 kHz-ensures accurate differential measurements in noisy industrial environments. |
| Reference Voltage | 4.096 V internal-provides stable scaling for full-scale conversion with ±5 ppm/°C drift when enabled. |
| Supply Voltages | VDDH = +15 V, VSSH = −15 V, AVDD/DVDD = 5 V, VIO = 1.8–5 V-requires isolated dual-rail analog supply design. |
Pinout & Package
LFCSP-40 (6 mm × 6 mm, exposed paddle), RoHS-compliant, thermal pad connected to VSSH for optimal heat dissipation and noise immunity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN0–IN7 | Analog Input Channels | Eight high-impedance inputs supporting single-ended or differential configurations; each referenced to COM. |
| COM | Common Input Reference | Shared reference node for IN[7:0]; voltage range up to ±10.24 V (±12.228 V at PGIA gain 0.16). |
| AUX+, AUX− | Auxiliary ADC Inputs | Dedicated differential pair for secondary measurements; ±4.096 V input range, independent of main PGIA path. |
| CS, DIN, SCK, SDO, BUSY, CNV | SPI-Compatible Digital Interface | 4-wire serial interface (1.8–5 V compatible); BUSY indicates active conversion; CNV initiates sampling on rising edge. |
| VDDH, VSSH | High-Voltage Analog Supplies | +15 V / −15 V rails powering multiplexer and PGIA; require ≥2.5 V headroom from input signals. |
| REF1, REF2, REFIN, REFN, RCAP | Reference Subsystem | Supports internal 4.096 V reference or external reference; RCAP supplies reference buffer; REFN is reference ground. |
| AGND, DGND, RGND | Separate Ground Planes | Physically isolated analog, digital, and reference grounds prevent coupling noise into sensitive conversion paths. |
| ACAP, DCAP | Internal Analog/Digital LDO Outputs | 2.5 V regulated supplies for ADC core (ACAP) and digital logic (DCAP); require local 10 µF + 0.1 µF decoupling. |
Key Features
| Feature | Design Value |
|---|---|
| No latency or pipeline delay | SAR architecture ensures deterministic, zero-cycle-delay conversion results-critical for closed-loop control timing. |
| User-programmable input ranges | Eight differential or four fully differential ranges (±1 V to ±10.24 V) selected via configuration register-eliminates external gain-switching circuitry. |
| Channel sequencer with individual gains | Hardware-controlled scan of all 8 channels with per-channel PGIA gain setting-enables mixed-signal acquisition without host intervention. |
| On-chip 4.096 V reference and buffer | Integrated precision reference with ±5 ppm/°C drift and 250 µA output drive-removes need for external reference IC and reduces BOM count. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar multichannel precision data acquisition applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADAS3023BSTZ | Same architecture but with 18-bit resolution and 500 kSPS throughput; higher integral linearity (±1.5 LSB vs. ±2 LSB) and improved SNR (93 dB vs. 91.5 dB). | Better suited for metrology-grade applications requiring enhanced DC accuracy and lower noise floor. | Select ADAS3023BSTZ when 18-bit resolution and <1 LSB INL are mandatory; accept 50% lower throughput and higher power consumption. |
| AD7606BSTZ | 8-channel, 16-bit, 200 kSPS SAR ADC with integrated analog front-end; lacks on-chip PGIA and uses external reference only; simpler interface (parallel + SPI). | Targeted at cost-sensitive, lower-speed DAQ where per-channel gain flexibility is not required. | Choose AD7606BSTZ for fixed-gain, lower-throughput systems needing reduced design complexity and smaller PCB area. |
Compared with ADAS3022BSTZ, ADAS3023BSTZ trades speed for resolution and accuracy in metrology use cases, while AD7606BSTZ sacrifices programmable gain and throughput for integration simplicity and cost efficiency in general-purpose industrial logging.

FAQ
What is the maximum differential input voltage supported by the ADAS3022BSTZ?
The ADAS3022BSTZ supports a maximum differential input voltage of ±24.576 V when using ±15 V analog supplies and PGIA gain of 0.16. This value scales inversely with PGIA gain-for example, ±10.24 V at gain 0.4 and ±1.28 V at gain 6.4. All values are specified with respect to the internal 4.096 V reference and validated per Table 2 of the Rev. D datasheet. The ADAS3022BSTZ maintains full 16-bit linearity across these ranges.
Does the ADAS3022BSTZ require external reference components?
No-the ADAS3022BSTZ includes a fully integrated 4.096 V reference with buffer, requiring only external 10 µF + 0.1 µF decoupling on REF1/REF2. External reference operation is optional and supported via REFIN/REFx pins, but the internal reference delivers ±5 ppm/°C drift and eliminates need for external precision references in most industrial applications. The ADAS3022BSTZ reference subsystem is self-contained and production-validated.
How does the channel sequencer function in the ADAS3022BSTZ?
The ADAS3022BSTZ channel sequencer is a hardware-controlled state machine that automatically cycles through all eight input channels (IN0–IN7) in user-defined order, applying individual PGIA gain settings per channel stored in the configuration register. It operates independently of the host processor, enabling continuous background acquisition without SPI overhead. Each conversion result includes associated channel and gain metadata, and the ADAS3022BSTZ supports both continuous and on-demand sequencing modes per Section 39 of the datasheet.
What are the power supply requirements for the ADAS3022BSTZ?
The ADAS3022BSTZ requires five distinct supply domains: VDDH (+15 V), VSSH (−15 V), AVDD (5 V), DVDD (5 V), and VIO (1.8–5 V). Critical decoupling includes 10 µF + 0.1 µF capacitors on ACAP, DCAP, RCAP, VDDH, and VSSH. The device draws 3.5 mA (typ) on VDDH and 19 mA (typ) on AVDD at PGIA gain 6.4 with reference buffer enabled. All supplies must meet ±5% tolerance and low-noise specifications per Table 2 and Section 31 of the ADAS3022BSTZ datasheet.
Is the ADAS3022BSTZ pin-compatible with other devices in the ADAS30xx family?
The ADAS3022BSTZ shares identical LFCSP-40 pinout and footprint with ADAS3023BSTZ (18-bit variant), enabling drop-in replacement where resolution upgrade is acceptable. However, it is not pin-compatible with AD7606BSTZ (different package, fewer pins, no VDDH/VSSH) or ADAS3022BCPZ (LQFP-48 variant). Pin compatibility is strictly limited to ADAS3022BSTZ and ADAS3023BSTZ per Analog Devices' ordering guide and mechanical drawings in Rev. D datasheet.
