TS7001IM8 Equivalent & Substitute Parts

Part Overview

The TS7001IM8 is a 12-bit Analog to Digital Converter (ADC) manufactured by Silicon Labs, featuring 2 single-ended inputs with a SAR (Successive Approximation Register) architecture and SPI/DSP data interface. Designed for data acquisition applications, this device operates at a 187.5 kSPS sampling rate with external or internal reference capability.

The TS7001IM8 is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain reliability, and support legacy system maintenance or redesign initiatives.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TS7001IM8 is based on the following critical parameters:

• Resolution and Architecture: 12-bit SAR ADC architecture is the primary functional requirement
• Input Configuration: 2 single-ended inputs must be maintained
• Data Interface: SPI compatibility is essential for system integration
• Supply Voltage Range: Operating voltage compatibility within specified ranges
• Package and Mounting: Surface mount 8-pin packages with compatible pinouts
• Operating Temperature: -40°C to 85°C range support
• Reference Type: External reference capability is required

The TLV2542IDGK from Texas Instruments meets these substitution criteria. While it offers an extended analog and digital supply voltage range (2.7V to 5.5V) and a higher sampling rate (200 kSPS), it maintains functional equivalence through identical resolution, input count, input type, SAR architecture, SPI interface, and operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

The TLV2542IDGK is an active product with ROHS3 compliance and REACH unaffected status, providing supply chain assurance for new designs and legacy system support. The extended supply voltage range (2.7V to 5.5V) offers greater design flexibility compared to the TS7001IM8's 2.7V to 3.6V range, while maintaining identical resolution, input configuration, and operating temperature specifications.

The TLV2542IDGK's higher sampling rate (200 kSPS versus 187.5 kSPS) represents a performance enhancement. The package transition from 8-MSOP to 8-VSSOP requires PCB layout verification to ensure mechanical and electrical compatibility, though both are 8-pin surface mount packages with 0.118" width.

Frequently Asked Questions (FAQ)

Q: Can the TLV2542IDGK directly replace the TS7001IM8 in existing designs?

A: Functional replacement is possible due to matching resolution, input count, input type, SAR architecture, and SPI interface. However, package geometry differs (8-MSOP versus 8-VSSOP), requiring PCB layout modification and pinout verification before implementation.

Q: What is the impact of the extended supply voltage range on the TLV2542IDGK?

A: The TLV2542IDGK supports 2.7V to 5.5V for both analog and digital supplies, compared to the TS7001IM8's 2.7V to 3.6V range. This provides design flexibility for systems operating at higher voltages while remaining compatible with 3.3V applications.

Q: Does the higher sampling rate of the TLV2542IDGK affect system design?

A: The TLV2542IDGK's 200 kSPS sampling rate exceeds the TS7001IM8's 187.5 kSPS specification. This represents improved performance and does not negatively impact designs; however, signal processing firmware may require evaluation to ensure compatibility with the faster conversion rate.

Q: What are the package considerations for substitution?

A: Both devices use 8-pin surface mount packages with identical width (0.118", 3.00mm). The TS7001IM8 uses 8-MSOP packaging while the TLV2542IDGK uses 8-VSSOP packaging. Pinout compatibility must be verified, and PCB footprints require adjustment to accommodate the package transition.

Q: Is the TLV2542IDGK suitable for new product designs?

A: Yes. The TLV2542IDGK is an active product with ROHS3 compliance and established supply availability, making it appropriate for new designs requiring 12-bit, 2-input SAR ADC functionality with SPI interface.
