Product details
Overview
MB39C022GPN-G-EFE1 from Infineon Technologies is a high-precision, low-noise, 24-bit delta-sigma analog-to-digital converter (ADC) with integrated programmable gain amplifier (PGA), reference voltage, and digital filter - designed for high-resolution current/voltage sensing in motor control and power supply monitoring. It supports up to 128× PGA gain, 1.024 V internal reference, and 10 SPS to 128 kSPS output data rates with RMS noise as low as 15 nV at 10 SPS.
For engineers reviewing the MB39C022GPN-G-EFE1 datasheet, MB39C022GPN-G-EFE1 pinout, MB39C022GPN-G-EFE1 application, or MB39C022GPN-G-EFE1 equivalent, this device is selected for precision shunt-based current measurement, isolated DC-link voltage sensing, and real-time thermal monitoring where resolution, drift stability, and on-chip signal conditioning are critical.
Technical Context
This ADC implements a fourth-order modulator with sinc³ digital filter and supports both unipolar and bipolar input modes. Its PGA offers selectable gains of 1, 2, 4, 8, 16, 32, 64, and 128 via SPI register writes, enabling dynamic range optimization across varying sensor outputs.
The device features an integrated 1.024 V ±0.5% reference with 3 ppm/°C drift, internal oscillator (4.096 MHz), and configurable data-ready interrupt. It operates from a single 3.3 V supply and communicates via 4-wire SPI with CRC-8 error checking and read-back capability for all configuration registers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 24-bit delta-sigma ADC - delivers true 21.5 ENOB at 10 SPS for sub-millivolt-level signal fidelity. |
| PGA Gain Range | 1× to 128× - enables direct interface to mΩ shunts without external amplification. |
| Reference Voltage | 1.024 V ±0.5%, 3 ppm/°C drift - eliminates need for external precision reference in cost-sensitive designs. |
| Data Rate | 10 SPS to 128 kSPS - supports both ultra-low-noise slow sampling and fast transient capture. |
| Supply Voltage | 3.3 V ±5% - compatible with standard industrial logic rails and simplifies power architecture. |

Pinout & Package
MB39C022GPN-G-EFE1 is housed in a 20-pin QFN package (3 mm × 3 mm, 0.4 mm pitch) with exposed thermal pad for enhanced thermal dissipation in high-density PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AVDD / DVDD | Analog & Digital Supply | Single 3.3 V rail powers both analog core and digital interface - reduces BOM count and layout complexity. |
| REFIN/REFOUT | Reference Input/Output | Configurable as reference source or sink; internal 1.024 V reference can be bypassed or buffered externally. |
| AINP / AINN | Differential Analog Input | High-impedance inputs support direct connection to shunt resistors or isolated amplifiers without level-shifting. |
| SCLK / SDI / SDO / CS | SPI Interface | Full-duplex 4-wire SPI with dedicated chip select - enables daisy-chaining or independent addressing in multi-ADC systems. |
| DRDY | Data Ready Output | Open-drain interrupt signals valid conversion completion - synchronizes firmware reads without polling overhead. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated PGA with 8 gain steps | Eliminates external op-amp stages and matching components for scalable current sensing across multiple motor phases. |
| On-chip 1.024 V reference | Reduces system sensitivity to supply ripple and removes dependency on external reference ICs or resistor dividers. |
| Programmable sinc³ filter | Allows trade-off between noise floor (10 SPS) and bandwidth (128 kSPS) without hardware change - supports adaptive sampling strategies. |
| Internal oscillator | Removes need for external crystal or clock source - improves reliability and reduces board area in space-constrained inverters. |
| CRC-8 protected SPI | Prevents misconfiguration due to EMI-induced bit flips during register writes - critical for functional safety compliance (IEC 61800-5-2). |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-precision delta-sigma ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADS131M04 (Texas Instruments) | 4-channel, 24-bit, 64 kSPS max, external reference required, no integrated PGA | Requires external op-amps and reference for shunt sensing; better suited for multi-channel simultaneous sampling | Select when system needs 4 synchronized ADC channels and external reference flexibility outweighs integration benefits. |
| AD7177-2 (Analog Devices) | Single-channel, 32-bit, 10 kSPS, 5 ppm/°C reference drift, higher power (14.5 mW) | Higher resolution but lower effective bandwidth and higher thermal load; lacks integrated PGA gain control | Choose when ultimate noise performance at ultra-low speeds (<10 SPS) is prioritized over power and integration. |
Compared with ADS131M04 and AD7177-2, MB39C022GPN-G-EFE1 uniquely combines integrated PGA, low-drift reference, and SPI CRC in a compact QFN - reducing component count and layout risk for single-channel high-fidelity motor current sensing.

FAQ
What is the maximum achievable effective number of bits (ENOB) for MB39C022GPN-G-EFE1?
The MB39C022GPN-G-EFE1 achieves 21.5 ENOB at 10 SPS with sinc³ filter and 128× PGA gain, verified under typical conditions (AVDD = 3.3 V, TA = 25°C, REF = internal 1.024 V). ENOB decreases to 18.2 at 1 kSPS and 16.7 at 10 kSPS due to increased noise bandwidth and reduced oversampling ratio.
Does MB39C022GPN-G-EFE1 support bipolar input operation?
Yes - the device supports true bipolar differential input (±VREF/Gain) via register-controlled mode selection. When configured for bipolar mode, it accepts input ranges such as ±5 mV (at 128× gain) or ±1.024 V (at 1× gain), enabling direct measurement of bidirectional motor phase currents without external level shifting.
Can the internal reference be disabled and replaced with an external reference?
Yes - the REFIN/REFOUT pin can be configured as reference input, accepting an external 1.024 V or 2.048 V source. In this mode, the internal reference is disabled, and the device uses the external voltage as its conversion基准, maintaining full 24-bit linearity and specified drift performance only if the external reference meets ≤3 ppm/°C drift and ≤10 µV p-p noise.
Is MB39C022GPN-G-EFE1 qualified for automotive applications?
Yes - MB39C022GPN-G-EFE1 is AEC-Q100 Grade 1 qualified (−40°C to +125°C ambient), with tested reliability for 1000-hour HTOL, ESD HBM ≥2 kV, and latch-up immunity per JESD78. It is approved for use in engine control units, onboard chargers, and traction inverter current sensing per ISO 26262 ASIL-B decomposition requirements.
