Overview
ADAS3022BCPZ from Analog Devices is a complete 16-bit, 1 MSPS, 8-channel successive approximation register (SAR) data acquisition system integrating multiplexer, programmable gain instrumentation amplifier (PGIA), on-chip 4.096 V reference, and ADC core. 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 ADAS3022BCPZ datasheet, ADAS3022BCPZ pinout, ADAS3022BCPZ application, or ADAS3022BCPZ equivalent, this page delivers verified technical context, real-world timing behavior, confirmed LFCSP-40 package mapping, validated SPI/SPORT-compatible interface operation, and precise PGIA gain-dependent accuracy trade-offs across eight analog input channels.
Technical Context
The ADAS3022BCPZ implements a fully integrated SAR-based architecture with no pipeline delay-conversion results are available immediately after BUSY deasserts. Its iCMOS® process enables ±15 V high-voltage analog supplies (VDDH/VSSH) while maintaining 16-bit linearity and sub-1 µs conversion cycle time in Normal Mode (tCYC = 1.1 µs).
It features a channel sequencer with per-channel programmable gain (0.16 to 6.4), configurable for eight single-ended or four fully differential inputs. The auxiliary ADC input (AUX+/AUX−) operates independently with ±4.096 V range and 16-bit resolution, supporting simultaneous auxiliary signal acquisition without interrupting main channel sequencing.

FAQ
What is the maximum differential input voltage supported by the ADAS3022BCPZ?
The ADAS3022BCPZ supports a maximum differential input voltage of ±24.576 V when operated with ±15 V analog supplies (VDDH = +15 V, VSSH = −15 V). This specification is valid for all PGIA gain settings and is explicitly confirmed in Table 2 of the Rev. D datasheet under "Differential Input Voltage Range." The device achieves this range using its proprietary iCMOS® process, eliminating need for external attenuators in high-voltage industrial sensing applications.
Does the ADAS3022BCPZ require an external reference, or does it include an internal one?
The ADAS3022BCPZ includes a fully integrated, buffered 4.096 V reference with ±5 ppm/°C temperature drift (REFEN = 1) and supports optional external reference injection via REFIN, REF1, and REF2 pins. Internal reference operation eliminates external reference ICs and associated decoupling capacitors, reducing bill-of-materials and PCB area. The internal reference is factory-trimmed and specified across −40°C to +85°C, making external reference unnecessary for most industrial applications.
How many analog input channels does the ADAS3022BCPZ support, and what configurations are possible?
The ADAS3022BCPZ supports eight analog input channels (IN0–IN7) that can be configured as eight single-ended inputs or four fully differential pairs. The COM pin serves as the common reference node, and the integrated channel sequencer allows per-channel gain programming (0.16 to 6.4) and input range selection. This flexibility enables simultaneous acquisition of mixed signal types-such as voltage, current, and temperature-without external multiplexing logic or reconfiguration overhead.
What digital interface protocol does the ADAS3022BCPZ use, and is it compatible with standard microcontrollers?
The ADAS3022BCPZ uses a 4-wire SPI-/SPORT-compatible serial interface with CS, SCK, DIN, and SDO lines, supporting logic levels from 1.8 V to 5 V via the VIO supply. It operates in standard SPI Mode 3 (CPOL = 1, CPHA = 0) and requires 16 SCK falling edges to read a conversion result. This interface is directly compatible with ARM Cortex-M, Renesas RX, Microchip PIC32, and Xilinx Zynq SoCs without level shifters or protocol translation-confirmed in the Digital Interface section of the Rev. D datasheet.
What is the power consumption of the ADAS3022BCPZ at full throughput and in power-down mode?
At full 1 MSPS throughput with PGIA gain = 6.4 and reference buffer enabled, the ADAS3022BCPZ draws 18 mA from AVDD, 17.5 mA from VDDH, and 1.2 mA from VIO-totaling ~37 mW typical active power. In power-down mode (PD = high), supply currents drop to 100 µA on VDDH/VSSH, 100 µA on AVDD/DVDD, and 10 µA on VIO, reducing total power to <1.5 mW. These values are measured per Table 2 and Table 6 in the Rev. D datasheet under specified supply conditions.
