TPAFE0808-LFPR-S

ADCs/DACs - Special Purpose Overview

The TPAFE0808-LFPR-S is an 8-channel configurable analog front-end featuring integrated 12-bit ADCs, DACs, and GPIOs. It utilizes a successive approximation ADC with a 2 µs conversion time and supports input ranges of 0 to VREF or 0 to 2×VREF. The device includes eight 12-bit resistor-string DACs with output settling times of 10 µs. An internal 2.5 V reference provides ±0.1% accuracy, complemented by a temperature sensor with ±3 °C precision. Communication occurs via an I²C interface supporting up to 400 kHz. The component operates within a supply voltage range of 2.7 V to 5.5 V and functions across temperatures from −40°C to +125°C.

ADCs/DACs - Special Purpose Feature Summary

• Eight configurable channels supporting independent ADC, DAC, or GPIO modes
• Integrated 12-bit ADC with 2 µs conversion time and 8 MHz full power bandwidth
• Eight 12-bit DACs with 10 µs settling time and rail-to-rail output buffers
• Internal 2.5 V reference with 20 ppm/°C temperature coefficient

ADCs/DACs - Special Purpose Applications

• Multi-channel industrial control and monitoring systems
• General-purpose analog signal acquisition and digital output generation
• Embedded sensor interfaces requiring mixed-signal processing

ADCs/DACs - Special Purpose Procurement Notes

Verify the QFN3X3-16 package designation for the LFPR suffix against physical markings. Confirm that the operating environment remains within the specified -40°C to +125°C range. Ensure I/O voltage levels match the VLOGIC supply requirements for reliable serial communication.

ADCs/DACs - Special Purpose Selection Notes

Select this component when space-constrained designs require multiple ADC/DAC/GPIO functions in a single package. The internal 2.5 V reference eliminates external components for standard voltage ranges. Verify that the required sampling rate does not exceed the multiplexer switching limits and that the I²C bus speed matches the master controller capabilities.

ADCs/DACs - Special Purpose Part Context

The TPAFE0808-LFPR-S belongs to the TPAFE0808 product family manufactured by 3PEAK. It shares functional specifications with the WLCSP2x2-16 variant (TPAFE0808-WS2R), differing only in the surface-mount package type. Both variants provide identical electrical performance and register maps.

ADCs/DACs - Special Purpose Replacement Considerations

The TPAFE0808-WS2R serves as a direct pin-compatible alternative utilizing the WLCSP2x2-16 package. No other cross-model substitutes are documented in the official datasheet.
