ADS8422IPFBR Equivalent & Substitute Parts

Part Overview

The ADS8422IPFBR 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 SAR (Successive Approximation Register) architecture device operates at 4M samples per second and is housed in a 48-TQFP package. The part is currently in active production status with 2320 units available in new original inventory.

Substitute parts are identified when design requirements necessitate alternative packaging formats, procurement flexibility, or inventory optimization while maintaining identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the ADS8422IPFBR is determined by strict equivalence across the following critical parameters:

• Resolution: 16 bits
• Sampling Rate: 4M samples per second
• Input Configuration: 1 differential input
• Architecture: SAR-based analog to digital conversion
• Data Interface: Parallel output
• Supply Voltage Range: Digital 2.7V ~ 5.25V, Analog 5V
• Operating Temperature Range: -40°C ~ 85°C
• Package Type: 48-TQFP (7x7)
• Mounting: Surface Mount

The identified substitute part maintains identical electrical performance and mechanical compatibility. Differences are limited to packaging format (tape and reel configuration) and inventory source, which do not affect functional equivalence or circuit board integration.

Parameter Comparison

Engineering Selection Recommendations

Both the ADS8422IPFBR and ADS8422IBPFBT are active production devices from Texas Instruments with identical electrical specifications and mechanical compatibility. Selection between these parts should be based on procurement requirements and packaging format availability.

The ADS8422IPFBR is suitable for standard component procurement workflows. The ADS8422IBPFBT, supplied in Cut Tape and Digi-Reel format, is appropriate for high-volume manufacturing environments requiring automated component handling and tape-and-reel packaging.

Both parts maintain ROHS3 compliance and identical moisture sensitivity ratings, ensuring equivalent reliability and environmental performance across all applications. No functional or performance differences exist between these devices.

Frequently Asked Questions (FAQ)

Q: Can ADS8422IBPFBT be used as a direct replacement for ADS8422IPFBR?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format. ADS8422IBPFBT is supplied in Cut Tape and Digi-Reel format, while ADS8422IPFBR uses standard packaging. Both are pin-compatible and functionally equivalent in circuit applications.

Q: What determines substitution eligibility for this ADC?

A: Substitution is valid when parts maintain identical resolution (16 bits), sampling rate (4M SPS), input configuration (1 differential input), supply voltage ranges (2.7V ~ 5.25V digital, 5V analog), operating temperature range (-40°C ~ 85°C), and package type (48-TQFP). All these parameters are identical between the main part and substitute.

Q: Are there any compliance or certification differences?

A: No. Both parts carry identical ROHS3 compliance status, REACH unaffected designation, and MSL rating of 2 (1 Year). Regulatory and environmental certifications are equivalent.

Q: Does packaging format affect circuit board integration?

A: No. Both parts use the same 48-TQFP (7x7) package with surface mount configuration. Packaging format differences (tape and reel versus standard) relate only to procurement and handling, not to PCB footprint or electrical performance.

Q: What is the base product number for these parts?

A: Both ADS8422IPFBR and ADS8422IBPFBT share the base product number ADS8422, confirming their functional equivalence.
