ADS8401IPFBR

Analog To Digital Converters (ADC) Overview

The ADS8401IPFBR is a 16-bit, 1.25 MSPS analog-to-digital converter (ADC) from Texas Instruments, housed in a 48-lead TQFP package. It features a unipolar single-ended input range of 0 V to Vref and includes an onboard 4.096-V reference with a buffer. The device utilizes a capacitor-based SAR architecture with zero latency and supports both full 16-bit and 8-bit parallel data interfaces. Operating over the industrial temperature range of –40°C to 85°C, it consumes 155 mW at maximum throughput.

Analog To Digital Converters (ADC) Procurement Notes

Verify the 'BR' suffix indicates tape and reel packaging containing 1000 units per manufacturer specifications. Confirm the 'I' grade designation for integral linearity performance within the specified industrial temperature range. Ensure compatibility with the required 48-pin TQFP footprint during procurement planning.

Analog To Digital Converters (ADC) Selection Notes

Select this model for applications requiring high-speed, low-latency conversion with a unipolar input signal. The internal reference simplifies design by eliminating external components, provided the 4.096-V span meets system requirements. Consider the 8-bit read option if interfacing with microcontrollers having limited data bus width.

Analog To Digital Converters (ADC) Part Context

This component belongs to the ADS840x family of high-speed ADCs. The ADS8401 specifically offers a unipolar input configuration, distinguishing it from bipolar variants. It shares architectural similarities with other devices in the series but is optimized for single-supply operation and specific throughput requirements.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS8401IBPFBR serves as a higher-precision alternative within the same package and interface configuration. Verify pinout compatibility and power supply requirements when substituting between different linearity grades.
