ADS8344EB/2K5 Equivalent & Substitute Parts

Part Overview

The ADS8344EB/2K5 is a 16-bit Analog to Digital Converter (ADC) manufactured by Texas Instruments, designed for data acquisition applications requiring high-resolution signal conversion. This SAR (Successive Approximation Register) architecture device supports 4 or 8 differential and single-ended inputs with a 100 kSPS sampling rate and SPI digital interface. The component is actively produced and widely stocked, with 7,437 units currently available in inventory. Alternative equivalent parts may be required due to supply constraints, project redesigns, or specific procurement preferences while maintaining identical electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution eligibility for the ADS8344EB/2K5 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part ADS8344E/2K5 qualifies as a parametric equivalent based on the following criteria:

Key Substitution Parameters:

• Resolution: 16 bits (identical)
• Sampling Rate: 100 kSPS (identical)
• Input Configuration: 4, 8 differential and single-ended inputs (identical)
• Data Interface: SPI (identical)
• Supply Voltage Ranges: 2.7V ~ 3.6V, 5V analog and digital (identical)
• Operating Temperature: -40°C ~ 85°C (identical)
• Package: 20-SSOP surface mount (identical)
• Architecture: SAR (identical)
• Reference Type: External (identical)

Both parts share the same base product number (ADS8344) and are manufactured by Texas Instruments. The substitution is valid for direct replacement in applications where the ADS8344EB/2K5 is specified.

Parameter Comparison

Engineering Selection Recommendations

Both the ADS8344EB/2K5 and ADS8344E/2K5 are active products manufactured by Texas Instruments with identical electrical specifications and mechanical packaging. Selection between these parts should be based on availability and procurement requirements:

• ADS8344EB/2K5: 7,437 units in stock. Primary selection for immediate availability.
• ADS8344E/2K5: 2,876 units in stock. Alternative selection when primary part is unavailable.

Both parts maintain ROHS3 compliance, REACH unaffected status, and identical moisture sensitivity levels (MSL 3, 168 hours). No design modifications or circuit alterations are required when substituting between these parts. PCB layout, firmware, and application code remain unchanged.
