ADC08061CIWMX Equivalent & Substitute Parts

Part Overview

The ADC08061CIWMX is an 8-bit analog-to-digital converter manufactured by Texas Instruments, featuring a sigma-delta architecture with a single-ended input and parallel data interface. This component is classified as obsolete, making equivalent and substitute parts necessary for new designs and ongoing production support. The device operates with 5V analog and digital supply voltages and is housed in a 20-SOIC surface-mount package.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the ADC08061CIWMX is determined by the following critical parameters: 8-bit resolution, single-ended input configuration, parallel data interface, 20-SOIC package compatibility, and surface-mount technology. The substitute parts identified maintain these core functional and mechanical specifications while offering different architectural approaches and operational characteristics.

The two qualified substitute parts are:

TLC0820ACDW - Texas Instruments LinCMOS™ series flash architecture ADC with identical package and pin configuration. This part maintains 8-bit resolution, single-ended input, and parallel interface but operates at a lower sampling rate (392k samples/second) and supports a wider supply voltage range (4.5V to 8V).

AD7822BRZ - Analog Devices pipelined architecture ADC with 8-bit resolution, single-ended input, and parallel interface in the same 20-SOIC package. This part offers higher sampling rate (2M samples/second) and dual supply voltage support (2.7V to 3.3V or 5V) with extended temperature range matching the original device.

Parameter Comparison

Engineering Selection Recommendations

AD7822BRZ is the primary substitute for applications requiring direct functional replacement. This part maintains the extended operating temperature range (-40°C to 85°C) of the original ADC08061CIWMX, supports 5V supply operation, and delivers higher sampling performance (2M samples/second). Both devices are active products with current manufacturing support and ROHS3 compliance.

TLC0820ACDW serves as an alternative for applications where sampling rate requirements are lower than 392k samples/second. This part offers wider supply voltage tolerance (4.5V to 8V) but operates within a narrower temperature range (0°C to 70°C) and is not suitable for extended temperature applications. This substitute is appropriate only when the reduced operating temperature range and lower sampling rate are compatible with system requirements.

Frequently Asked Questions (FAQ)

Q: Can TLC0820ACDW replace ADC08061CIWMX in all applications?

A: No. The TLC0820ACDW operates within 0°C to 70°C, which excludes it from applications requiring the full -40°C to 85°C range of the original part. Additionally, its 392k samples/second rate is significantly lower than the ADC08061CIWMX's 1.5M samples/second. Verify your application's temperature and sampling rate requirements before selection.

Q: Is AD7822BRZ a direct pin-for-pin replacement?

A: Both AD7822BRZ and ADC08061CIWMX use the 20-SOIC package with identical physical dimensions. However, architectural differences (pipelined versus sigma-delta) may affect signal processing characteristics. Consult device datasheets for detailed pin assignments and functional behavior before PCB layout finalization.

Q: What are the supply voltage compatibility differences?

A: ADC08061CIWMX requires fixed 5V supplies. AD7822BRZ supports both 2.7V to 3.3V and 5V operation, providing design flexibility. TLC0820ACDW accepts 4.5V to 8V, offering the widest voltage tolerance but requiring verification of 5V nominal operation within this range.

Q: Are all substitute parts RoHS compliant?

A: Yes. ADC08061CIWMX, TLC0820ACDW, and AD7822BRZ are all ROHS3 compliant. All parts are also REACH unaffected and classified under ECCN EAR99.

Q: Which substitute is recommended for new designs?

A: AD7822BRZ is the recommended substitute for new designs. It maintains full temperature range compatibility, offers higher sampling performance, and is an active product with ongoing manufacturer support.
