TPAFE0808-WS2R

ADCs/DACs - Special Purpose Overview

The TPAFE0808-WS2R is an 8-channel configurable analog front-end from 3PEAK, packaged in WLCSP2x2-16. It integrates eight 12-bit ADCs, eight 12-bit DACs, and eight GPIOs. The device features a 2.5 V internal reference, an on-die temperature sensor, and I2C communication. Electrical specifications include a 12-bit resolution for both conversion types, ±2 LSB INL for the ADC, and a full-scale input range of 0 to VREF or 0 to 2×VREF. Operating voltage ranges from 2.7 V to 5.5 V, with an industrial temperature range of −40°C to +125°C.

ADCs/DACs - Special Purpose Feature Summary

• Eight configurable channels supporting independent ADC, DAC, or GPIO modes
• Integrated 12-bit successive approximation ADC with 2 µs conversion time
• Eight-channel 12-bit resistor-string DAC with rail-to-rail output buffer
• Internal 2.5 V reference with ±20 ppm/°C temperature coefficient

ADCs/DACs - Special Purpose Applications

• Multi-channel control and monitor systems
• General-purpose analog and digital I/O expansion
• Industrial sensor signal conditioning

ADCs/DACs - Special Purpose Procurement Notes

Verify the ordering suffix WS2R corresponds to the WLCSP2x2-16 package variant. Confirm supply chain authenticity through authorized 3PEAK distributors. Ensure ESD handling protocols meet ANSI/ESDA/JEDEC JS-001 (HBM 6 kV) standards during assembly.

ADCs/DACs - Special Purpose Selection Notes

Select this model for space-constrained designs requiring mixed-signal I/O. The WLCSP2x2-16 package offers lower thermal resistance (70 °C/W) compared to QFN variants. Ensure external reference requirements are met if the internal 2.5 V source is insufficient for specific application ranges.

ADCs/DACs - Special Purpose Part Context

This component belongs to the TPAFE0808 family, which also includes the TPAFE0808-LFPR-S in a QFN3X3-16 package. Both variants share identical electrical characteristics and pin functions, differing only in physical packaging and thermal performance metrics.

ADCs/DACs - Special Purpose Replacement Considerations

The TPAFE0808-LFPR-S is a direct functional substitute within the same product family, offering identical specifications in a QFN3X3-16 package. No other cross-model replacements are documented in the provided datasheet.
