ADS8406IPFBR

Analog To Digital Converters (ADC) Overview

The ADS8406IPFBR is a 16-bit, 1.25 MSPS analog-to-digital converter (ADC) manufactured by Texas Instruments. It utilizes a successive approximation register (SAR) architecture with an internal 4.096 V reference. The device supports pseudo-differential or single-ended inputs and operates on a 5 V analog supply and a 2.7 V to 5.25 V digital supply. Key performance metrics include a signal-to-noise ratio of 90 dB at 100 kHz input, integral nonlinearity of ±2 LSB, and differential nonlinearity of -1/+1.25 LSB. It is housed in a 48-lead TQFP package and functions within an industrial temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrates a high-speed 16-bit SAR ADC core with a built-in 4.096 V precision voltage reference to simplify system design.
• Supports flexible input configurations including pseudo-differential and single-ended modes for broad signal compatibility.
• Offers full 16-bit parallel data output or an 8-bit option accessible via two sequential read cycles.

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring high-resolution data acquisition.
• Medical instrumentation such as ultrasound imaging and patient monitoring devices.
• Automotive sensor interfaces and engine management systems.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix IPFBR corresponds to the tape-and-reel packaging variant when ordering. Confirm that the internal reference voltage requirement aligns with the application's accuracy needs. Ensure the parallel interface timing constraints are compatible with the host microcontroller or DSP. Check for moisture sensitivity level requirements during storage and handling.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a balance of high resolution and moderate speed is required without external reference circuitry. Compare against the ADS8405 if single-supply operation or different pinout constraints are necessary. Evaluate power consumption specifications against thermal limits in enclosed industrial enclosures. Consider the 48-pin TQFP footprint availability in the target PCB layout.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS840x family of high-performance 16-bit ADCs from Texas Instruments. It shares architectural similarities with the ADS8405 but includes an integrated voltage reference, distinguishing it from variants that require external references. The family is designed for applications demanding low power consumption and high accuracy in compact form factors.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS8405IBPFBT serves as a related variant within the same product family. Note that the ADS8405 typically lacks the internal reference found in the ADS8406, requiring external reference components for equivalent performance. Verify pin compatibility and software configuration differences before substitution.
