ADS8406IPFBT Equivalent & Substitute Parts

Part Overview

The ADS8406IPFBT is a 16-bit Analog to Digital Converter (ADC) manufactured by Texas Instruments, designed for data acquisition applications requiring single-channel differential input conversion. This device features a Successive Approximation Register (SAR) architecture with a sampling rate of 1.25 MSPS and operates across a wide supply voltage range of 2.7V to 5.25V digital supply with 5V analog supply.

The ADS8406IPFBT is classified as Obsolete. Locating equivalent substitute parts is necessary to support legacy system maintenance, design updates, and procurement continuity when original inventory becomes unavailable.

Substitute Part Grouping Explanation

Substitute parts for the ADS8406IPFBT are determined by strict equivalence across the following critical parameters:

• Resolution: 16 bits
• Sampling Rate: 1.25 MSPS
• Input Configuration: Single differential input
• Data Interface: Parallel output
• Architecture: SAR-based conversion
• Supply Voltage Ranges: Analog 5V, Digital 2.7V ~ 5.25V
• Package: 48-TQFP (7x7)
• Mounting: Surface Mount
• Operating Temperature Range: -40°C ~ 85°C
• Reference Configuration: External and Internal reference support

The ADS8406IBPFBT qualifies as a direct substitute based on identical electrical specifications and mechanical compatibility. The primary distinction is packaging format and product status.

Parameter Comparison

Engineering Selection Recommendations

The ADS8406IBPFBT is the direct substitute for the ADS8406IPFBT. Both devices share identical electrical and mechanical specifications, ensuring pin-for-pin and functional compatibility.

The ADS8406IBPFBT carries Active product status, providing access to current manufacturing, technical support, and supply chain continuity. This contrasts with the Obsolete status of the ADS8406IPFBT, making the substitute the preferred choice for new designs and ongoing production support.

Both parts maintain ROHS3 compliance and REACH Unaffected status, satisfying regulatory requirements for industrial and commercial applications. Moisture sensitivity classification (MSL 2, 1 Year) is identical, requiring equivalent handling and storage protocols.

The primary operational difference is packaging format: the ADS8406IPFBT uses standard packaging, while the ADS8406IBPFBT is supplied in Tape & Reel (TR) format. This distinction affects procurement volume requirements and automated assembly compatibility but does not impact electrical performance or functional operation.

Frequently Asked Questions (FAQ)

Q: Can the ADS8406IBPFBT directly replace the ADS8406IPFBT in existing designs?
