ADS850Y/2K Equivalent & Substitute Parts

Part Overview

The ADS850Y/2K is a 14-bit pipelined analog-to-digital converter manufactured by Texas Instruments, designed for data acquisition applications requiring single or differential input processing. This device operates at a 10 MHz sampling rate with parallel data interface output and is housed in a 48-TQFP surface mount package. The part is currently in active production status with ROHS3 compliance and is suitable for industrial and commercial applications operating across the -40°C to 85°C temperature range. Identifying equivalent substitute parts is necessary to ensure design flexibility, manage supply chain continuity, and maintain component availability across manufacturing cycles.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ADS850Y/2K are determined by strict equivalence across the following critical parameters:

• Resolution: 14-bit conversion capability
• Sampling Rate: 10 MHz minimum performance
• Input Configuration: Support for both differential and single-ended inputs
• Data Interface: Parallel output architecture
• Converter Architecture: Pipelined topology
• Supply Voltages: 5V analog and digital supply compatibility
• Package: 48-TQFP (7x7) surface mount form factor
• Temperature Range: -40°C to 85°C operational specification
• Compliance: ROHS3 and REACH compliance status

The ADS850Y/250 meets all these criteria and is classified as a parametric equivalent. The primary distinction between the main part and substitute relates to packaging configuration (tape and reel specifications), which does not affect electrical or mechanical compatibility in circuit design applications.

Parameter Comparison

Engineering Selection Recommendations

Both the ADS850Y/2K and ADS850Y/250 are active production parts from Texas Instruments with identical electrical and mechanical specifications. Selection between these parts should be based on packaging and supply chain requirements:

The ADS850Y/2K is supplied in standard packaging configuration suitable for direct component procurement. The ADS850Y/250 is supplied in Cut Tape and Digi-Reel packaging, which may be preferred for automated assembly operations or high-volume manufacturing environments.

Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory compatibility across global markets. The identical MSL rating of 2 (1 Year) requires equivalent moisture control and storage protocols during handling and assembly.

Frequently Asked Questions (FAQ)

Q: Can ADS850Y/250 be used as a direct replacement for ADS850Y/2K in existing designs?

A: Yes. The ADS850Y/250 is a parametric equivalent with identical electrical performance, pin configuration, and package dimensions. No circuit modifications are required for substitution.

Q: What is the difference between the two part numbers?

A: The primary difference is packaging configuration. ADS850Y/2K uses standard packaging, while ADS850Y/250 uses Cut Tape and Digi-Reel packaging. The electrical and mechanical specifications are identical.

Q: Are there any temperature or supply voltage differences between these parts?

A: No. Both parts operate across the identical -40°C to 85°C temperature range and require 5V analog and digital supply voltages.

Q: Do both parts support differential and single-ended input configurations?

A: Yes. Both the ADS850Y/2K and ADS850Y/250 support differential and single-ended input modes with identical signal processing characteristics.

Q: What is the significance of the 48-TQFP package specification?

A: The 48-TQFP (7x7 millimeter) package is a surface mount form factor with 48 pins. Both parts use this identical package, ensuring PCB footprint compatibility and assembly process compatibility.

Q: Are there any compliance or certification differences?

A: No. Both parts maintain identical ROHS3 compliance, REACH unaffected status, and MSL rating of 2 (1 Year), ensuring equivalent regulatory and environmental compliance.
