AD7875KPZ Equivalent & Substitute Parts

Part Overview

The AD7875KPZ is a 12-bit Analog to Digital Converter (ADC) manufactured by Analog Devices Inc., designed for single-ended input data acquisition applications. This SAR (Successive Approximation Register) architecture device operates with ±5V supply voltages and supports both SPI and parallel data interfaces. The part is currently in active production status with 988 units available in new original inventory. Alternative equivalent parts may be required due to supply constraints, design revisions, or inventory availability in specific regions.

Substitute Part Grouping Explanation

Equivalent substitution for the AD7875KPZ is determined by strict alignment of the following critical parameters:

  • Resolution: 12-bit ADC
  • Sampling Rate: 100k samples per second
  • Input Configuration: Single-ended input, 1 channel
  • Data Interface: SPI and Parallel support
  • Architecture: SAR-based conversion
  • Reference: Internal reference
  • Supply Voltages: ±5V analog and digital
  • Operating Temperature Range: 0°C to 70°C
  • Package: 28-PLCC (11.51x11.51) surface mount
  • Compliance: ROHS3 Compliant, REACH Unaffected

The AD7870LPZ meets all these parameters identically and is classified as a parametric equivalent. Both parts share the same base product lineage (AD7870/AD7875 series) and are manufactured by Analog Devices Inc. with identical electrical and mechanical specifications.

Engineering Selection Recommendations

Both the AD7875KPZ and AD7870LPZ are active production parts from Analog Devices Inc. with identical ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on:

  • Inventory availability and lead time requirements
  • Regional supply chain considerations
  • Cost optimization within procurement cycles
  • Existing stock levels (AD7875KPZ: 988 units; AD7870LPZ: 1027 units)

No functional or compliance differences exist between these parts. Direct substitution is supported without design modification or re-qualification.

Frequently Asked Questions (FAQ)

Q: Can AD7870LPZ be used as a direct replacement for AD7875KPZ?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, pin configurations, package dimensions, and compliance certifications. No circuit modifications are required.

Q: Are there any differences in pin configuration or PCB layout requirements?

A: No. Both parts use the 28-PLCC (11.51x11.51) surface mount package with identical J-Lead configuration. PCB footprints and layout are interchangeable.

Q: Do both parts support the same data interfaces?

A: Yes. Both AD7875KPZ and AD7870LPZ support SPI and parallel data interfaces with identical signal timing and protocol specifications.

Q: What is the operating temperature range for both parts?

A: Both parts operate across 0°C to 70°C. Ensure your application environment falls within this range.

Q: Are there any supply voltage differences?

A: No. Both parts require identical ±5V analog and digital supply voltages.

Q: Which part should I select for new designs?

A: Either part is suitable for new designs. Selection should be based on current inventory availability and supplier lead times. Both are active production parts with equivalent long-term availability.

Q: Is moisture sensitivity a concern during storage or assembly?

A: Both parts have MSL 3 rating (168 hours). Standard moisture control procedures during PCB assembly are required. No difference exists between the two parts in this regard.
