ADC1061CIWM Equivalent & Substitute Parts

Part Overview

The ADC1061CIWM is a 10-bit flash analog-to-digital converter manufactured by Texas Instruments, housed in a 20-SOIC surface mount package. This device features a single-ended input with parallel data interface and operates across the industrial temperature range of -40°C to 85°C. The product is classified as obsolete, making identification of suitable substitute components essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ADC1061CIWM is determined by the following critical parameters:

• Resolution: 10-bit conversion capability
• Package Compatibility: 20-SOIC form factor with identical 0.295" (7.50mm) width
• Supply Voltage: Dual 5V analog and digital supply rails
• Operating Temperature Range: -40°C to 85°C industrial specification
• Compliance Standards: ROHS3 compliance and REACH unaffected status

The TLC1518IDW qualifies as a substitute based on matching resolution, package form factor, supply voltage requirements, and operating temperature range. While the TLC1518IDW employs a SAR (Successive Approximation Register) architecture with SPI interface and supports multiple input channels, these differences do not preclude substitution when the application requirements permit interface protocol adaptation and the single-input constraint of the original design is not a limiting factor.

Parameter Comparison

Engineering Selection Recommendations

The TLC1518IDW is an active product from Texas Instruments and represents the primary substitute for the obsolete ADC1061CIWM. Both devices maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for current manufacturing environments.

Selection of the TLC1518IDW requires accommodation of interface protocol differences. The original ADC1061CIWM employs parallel data output, while the TLC1518IDW utilizes SPI serial communication. System designs must incorporate appropriate signal conditioning and microcontroller interface modifications to support this protocol transition.

The TLC1518IDW's expanded input channel capability (7 or 8 channels versus 1 channel) and SAR architecture provide enhanced flexibility for multi-channel applications, though single-channel operation remains fully supported through channel selection.

Frequently Asked Questions (FAQ)

Q: Can the TLC1518IDW directly replace the ADC1061CIWM without circuit modifications?

A: Physical package compatibility exists (both 20-SOIC), and supply voltage requirements are identical. However, the data interface differs fundamentally: ADC1061CIWM uses parallel output while TLC1518IDW uses SPI serial interface. Circuit redesign is required to accommodate this protocol change.

Q: What are the key differences between flash and SAR architectures in this context?

A: Flash architecture (ADC1061CIWM) provides simultaneous conversion of all bits, resulting in faster conversion speed. SAR architecture (TLC1518IDW) converts bits sequentially, typically requiring more conversion time but offering lower power consumption. Both achieve 10-bit resolution and operate within the specified temperature range.

Q: Are there any compliance or certification concerns with substitution?

A: Both devices maintain ROHS3 compliance and REACH unaffected status. No additional compliance barriers exist for substitution in applications requiring these certifications.

Q: Does the TLC1518IDW's multi-channel capability affect single-channel operation?

A: No. The TLC1518IDW supports single-channel operation through channel selection via SPI commands. Unused channels remain inactive without impact on the selected channel's performance.

Q: What is the inventory status for these components?

A: ADC1061CIWM inventory is 2098 pieces (new original stock). TLC1518IDW inventory is 1374 pieces (new original stock, tube packaging). Both are currently available.
