NXP Semiconductors' Highly-Configurable, Industrial-Grade NAFEx88 Analog Front End Now Available from Mouser
September 3, 2024 – Mouser Electronics, Inc., the authorized global distributor with the newest electronic components and industrial automation products, is now stocking the NAFEx88 analog front-end (AFE) ICs from NXP Semiconductors. The industrial-grade NAFEx88 AFE ICs are highly configurable and versatile, with eight universal input channels. The NAFEx88 AFE ICs meet the precise measurement requirements of data acquisition systems, industrial automation and process control, and programmable logic controllers (PLC).
The NXP Semiconductors NAFEx88 AFEs, now available at Mouser, integrate low-leakage, high-voltage (HV) fast multiplexers, low-offset and low-drift programmable gain amplifiers (PGA), and buffers. The ICs feature eight configurable HV inputs that support single-ended or differential ranges up to ±25V. Each input can be independently configured for voltage, current, resistance, Resistance Temperature Detector (RTD), and thermocouple. The NAFEx88 AFE ICs achieve 0.005% full scale (FS) accuracy at room temperature after user calibration and maintain 0.1% FS accuracy across the -25°C to 105°C temperature range. The HV analog pins are diode-protected internally for electromagnetic compatibility (EMC) and miswiring scenarios.
The ICs also include a diagnostic system for anomaly detection and prediction, as well as CRC error detection. The NAFEx88 ICs feature a high data-rate 24-bit Delta-Sigma Analog-to-Digital Converter (ADC), as well as precise voltage and current excitation sources. The ICs feature an operating temperature range of -40°C to 125°C and are delivered in a 64-pin, 9 mm2 x 0.85 mm HVQFN package. The NAFE13388 and NAFE73388 ICs are factory-calibrated, while the NAFE13188 IC is non-factory calibrated. The NAFE73388 supports high-speed data rates up to 576 kSPS.
The NAFEx88-EVB evaluation board provides an easy-to-use evaluation platform for the NAFEx88 AFE ICs. The evaluation board supports voltage, current, RTD, and thermocouple measurements for quick and easy development. The evaluation board is also available in a kit (KITNAFE13388-EVB), which includes a microcontroller board for further ease of use.
