OPT3101RHFT

Analog Front End (AFE) Overview

The OPT3101RHFT is a Time-of-Flight (ToF) based analog front-end (AFE) integrated circuit manufactured by Texas Instruments. It is designed for long-range proximity and distance sensing applications using continuous wave phase-shift technology. The device integrates a complete depth processing pipeline, including an ADC, timing sequencer, and digital processing engine. Key electrical specifications include a supply voltage range of 1.7 V to 3.6 V, operation at sampling rates up to 4 kHz, and a 16-bit distance output resolution. It supports three transmitter channels and features high ambient light rejection capabilities.

Analog Front End (AFE) Feature Summary

• Integrated ToF AFE with 16-bit distance output and up to 4 kHz sampling rate
• Supports 3 transmitter channels for multi-zone operation and extended range via de-aliasing
• Built-in illumination drivers with programmable current control up to 173 mA
• High ambient light suppression performance suitable for harsh environments

Analog Front End (AFE) Applications

• Obstacle detection and avoidance for drones and autonomous vehicles
• Precise long-range distance measurement in factory automation
• Non-contact distance or level measurement in challenging environments

Analog Front End (AFE) Procurement Notes

Verify the specific suffix 'RHFT' against the manufacturer's latest documentation to confirm package type and reel quantity. Check for any product change notices or end-of-life announcements, as availability status may vary. Ensure compatibility with required interface protocols such as I2C, SPI, or UART during integration planning.

Analog Front End (AFE) Selection Notes

Select this component when high-resolution distance measurement up to 15 meters is required without ambiguity. Consider the integrated LED drivers if minimizing external component count is a priority. Verify that the operating temperature range of -40°C to +85°C meets environmental requirements. Ensure the host system can support the necessary digital interfaces for configuration and data retrieval.

Analog Front End (AFE) Part Context
