AMC1203BPSAR Equivalent & Substitute Parts

Part Overview

The AMC1203BPSAR is a 16-bit Sigma-Delta analog-to-digital converter manufactured by Texas Instruments, designed for single-channel differential input data acquisition applications. This component operates at a 40 kHz sampling rate with SPI digital interface and internal voltage reference, suitable for precision measurement systems requiring low-power signal conversion.

The AMC1203BPSAR carries a Last Time Buy product status, indicating this part is approaching end-of-life. Identifying equivalent substitute parts ensures design continuity and supply chain reliability for ongoing production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AMC1203BPSAR is determined by strict equivalence across the following critical parameters:

• Resolution and Sampling Rate: 16-bit resolution at 40 kHz sampling rate
• Input Configuration: Single differential input channel
• Digital Interface: SPI protocol compatibility
• Converter Architecture: Sigma-Delta topology
• Supply Voltage Requirements: 5V analog and digital supplies
• Temperature Operating Range: -40°C to 105°C
• Package Specification: 8-SOIC form factor with 5.30mm width
• Compliance Standards: ROHS3 compliance and MSL 3 rating

The AMC1203PSAR meets all these criteria as a direct parametric equivalent, differing only in packaging designation (Tape & Reel format) while maintaining identical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The AMC1203PSAR serves as a direct substitute for the AMC1203BPSAR based on complete parametric equivalence. Both parts maintain identical electrical specifications, package dimensions, and compliance certifications. Selection between these variants depends on packaging and inventory availability rather than functional or mechanical differences.

Given the Last Time Buy status of both parts, long-term supply planning should evaluate alternative 16-bit Sigma-Delta ADC architectures from Texas Instruments or competing manufacturers if extended production lifecycles are required beyond current inventory levels.

Frequently Asked Questions (FAQ)

Q: Can the AMC1203PSAR replace the AMC1203BPSAR in existing designs?

A: Yes. The AMC1203PSAR is a parametric equivalent with identical electrical performance, pin configuration, and package dimensions. No design modifications are required for direct substitution.

Q: What is the difference between the BPSAR and PSAR designations?
