NAFE93352B40BS 概要
An analog front-end (AFE) is the circuit block that conditions and digitizes real-world analog signals - voltage, current, resistance, temperature - before they reach a digital processor. Within the signal-chain hierarchy, the AFE sits between sensors/actuators and an MCU: it multiplexes, amplifies, filters, and converts signals with an ADC and generates outputs with DACs and drivers. A software-configurable universal AFE replaces dozens of discrete signal-chain components, letting one silicon device adapt to many input types through register configuration.
Key features of the NAFE93352 include a 24-bit resolution sigma-delta conversion core, multiple simultaneously configurable analog input channels supporting voltage, current and resistance measurement modes, and integrated DAC-based outputs for closed-loop control. The universal input structure means PLC analog input modules can support ranges such as +/-10 V and 0/4-20 mA on the same footprint without hardware changes. As the high-speed family member, it prioritizes conversion throughput for fast process control loops.
The architecture integrates a precision reference input, programmable-gain signal path, and digital SPI interface for register-based configuration and data streaming, reducing external component count and calibration burden in I/O modules and data loggers.
Typical applications named by NXP include programmable logic controllers (PLC), process control systems, industrial I/O modules, and data loggers - domains that demand both multi-range analog acquisition and analog output drive from a single compact device.
A key design consideration is selecting between the NAFE93352 (high speed) and NAFE33352 (low power) variants early in the design: they share the same software model and package concept, so throughput versus power budget is the deciding parameter.

主な用途
NAFE93352B40BS の用途: 6 件s: Programmable Logic Controllers (PLC), Process Control Systems, Industrial I/O Modules, Data Loggers, Test and Measurement Instrumentation, Building and Energy Management Systems.
Programmable Logic Controllers (PLC)
The NAFE93352 fits PLC analog modules because a single software-configurable device can acquire multiple universal input types - voltage, current, resistance - with 24-bit precision while its DAC outputs drive control signals, replacing multiple fixed-function converter ICs. In a typical analog input card, the AFE sits behind channel protection and signal conditioning, digitizing sensor signals via SPI into the PLC processor with the high-speed conversion throughput needed for fast scan cycles. Its 2-channel structure and software-defined ranges let one hardware platform serve many I/O card variants, cutting BOM count and qualification effort. The industrial-grade design target means the front end maintains precision across the harsh electrical environment of a control cabinet, and the same-family NAFE33352 lets vendors offer low-power variants without firmware redesign.
おすすめ
Process Control Systems
In process control, the NAFE93352 provides the measurement backbone for loops that read transmitters (4-20 mA), bridge sensors, and voltage signals while simultaneously outputting actuator drive signals - all from one 24-bit AIO-AFE. The high-speed version is preferred when multiple loops must be scanned rapidly or when control bandwidths exceed what low-power front ends support. Its software configurability means a loop controller can be re-ranged in the field without hardware modification, a major advantage for retrofits and multi-product process lines. The precision conversion core helps preserve measurement integrity for temperature, pressure, and flow transmitters, while integrated outputs simplify closed-loop control architectures in distributed control system (DCS) I/O carriers.
おすすめ
Industrial I/O Modules
Modular industrial I/O systems benefit most directly from the NAFE93352's universal, software-configurable input/output structure: a single module design can be configured as voltage input, current input, or output channels by firmware, dramatically reducing the number of distinct card SKUs a vendor must manufacture and stock. The 24-bit resolution supports high-accuracy measurement cards, and the 2-channel architecture enables multi-channel scanning under SPI control from the module's communication controller. Because the NAFE33352 shares the same software model in a low-power grade, vendors can offer both standard and power-optimized module variants on one PCB layout. The HVQFN-40 (6x6 mm) footprint keeps channel density high on standard Eurocard-format I/O boards.
おすすめ
Data Loggers
Industrial data loggers use the NAFE93352 to digitize heterogeneous sensor inputs - thermocouples via precision measurement, 4-20 mA transmitters, and voltage signals - into a single 24-bit acquisition chain without analog redesign for each sensor type. The high-speed grade allows burst logging of fast events, while the software-configurable ranges let a logger adapt to different installed sensor sets via firmware. The 40-pin HVQFN (6x6 mm) package conserves board area in compact logger enclosures. Where battery operation dominates, engineers can select the same-family NAFE33352 low-power version with identical software configuration flow, preserving firmware investment. SPI streaming of conversion results into nonvolatile storage keeps the logger's MCU load low during continuous acquisition campaigns.
おすすめ
Test and Measurement Instrumentation
Bench and modular instruments leverage the NAFE93352's 24-bit conversion core and universal front end to implement multi-range acquisition channels in compact instruments such as data acquisition chassis, calibration sources, and process calibrators. The software-configurable architecture enables autoranging behavior purely in firmware, and the DAC outputs allow the same device to source calibration signals - useful in loop calibrators that must both measure and generate 4-20 mA and voltage levels. The high-speed NAFE93352 grade suits instruments requiring fast sampling on trigger events, while the precision resolution meets accuracy demands of measurement-grade products. The HVQFN-40 package supports dense multi-channel instrument front ends on small PCB sections.
おすすめ
Building and Energy Management Systems
Building management and energy monitoring controllers use the NAFE93352 to acquire diverse field signals - temperature sensors, current transducers, and utility voltage/current meters - with a common 24-bit front end, while generating analog outputs for valve and damper actuation. The universal software-configurable inputs let one controller hardware revision serve multiple building types and sensor standards through configuration rather than board changes, shortening product development cycles. The high-speed family grade supports fast demand-response control loops, and the same-family NAFE33352 offers a low-power option for battery-backed nodes. The compact HVQFN-40 (6x6 mm) footprint fits within space-constrained zone controller and room controller PCBs typical of HVAC and energy metering hardware.

設計ノート
Estimated: supply the NAFE93352 analog core from a low-noise LDO or filtered DC-DC rail; sigma-delta AFEs are sensitive to supply ripple on the reference and analog supplies. Because this is the high-speed family member, its power consumption exceeds the NAFE33352 low-power version - budget the thermal and supply design for the actual conversion-rate profile of your application, and consult the manufacturer datasheet for per-mode current figures before finalizing the power tree.
Place the HVQFN-40 exposed pad connection to a solid ground plane with an adequate via array - the exposed pad is both the main thermal and ground return path for the precision analog core. Partition the PCB so switching regulators, digital SPI lines, and communication interfaces stay physically separated from the AFE's analog input pins, and route analog inputs as short guarded traces from the front-end connector to the device pins.
Do not assume the NAFE33352 and NAFE93352 are timing-identical: they are the low-power and high-speed versions of the family respectively, so conversion settling and SPI throughput expectations differ between the two. Firmware written against the high-speed part must be re-validated against conversion timing tables in the respective datasheet. Additionally, universal inputs require correct external conditioning (shunts, dividers, protection) per measurement mode - misconfigured conditioning is the most common cause of out-of-spec accuracy in universal AFE designs.
