Highly-configurable and industrial-grade AFE now available

Mouser now stocks the NAFEx88 AFE ICs from NXP Semiconductors. These industrial-grade AFE ICs are highly configurable and versatile, with eight universal input channels. They meet the precise measurement needs of data acquisition systems, industrial automation and process control, and PLC.

The AFEs integrate low-leakage, high-voltage (HV) fast multiplexers, low-offset and low-drift 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, RTD, and thermocouple. After user calibration, the ICs achieve 0.005% full scale (FS) accuracy at room temperature and maintain 0.1% FS accuracy across the -25C to 105C temperature range. The HV analog pins are diode-protected internally for EMC and miswiring scenarios.

The ICs also include a diagnostic system for anomaly detection and prediction and CRC error detection. They feature a high-data-rate 24-bit Delta-Sigma ADC and precise voltage and current excitation sources. They have an operating temperature range of 40C to 125C and are delivered in a 64-pin, 9mm2 x 0.85mm 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 576kSPS.

The NAFEx88-EVB evaluation board provides an easy-to-use evaluation platform for the NAFEx88 AFE ICs. It supports voltage, current, RTD, and thermocouple measurements for quick and easy development. The board is also available in a kit (KITNAFE13388-EVB), which includes an MCU board for further ease of use.
