Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLV5636CDR is determined by the following critical parameters:

• Resolution: 12-bit DAC architecture
• Output Configuration: Single voltage output with buffered stage
• Interface Protocol: SPI serial communication
• Reference Support: Both external and internal reference capability
• Supply Voltage Range: Dual supply rails supporting 2.7V to 5.5V operation
• Package Compatibility: 8-SOIC surface mount form factor
• Regulatory Compliance: ROHS3 compliance and REACH unaffected status

The LTC1453CS8#PBF from Analog Devices Inc. meets these substitution criteria. Both devices share identical pin counts, package geometry, and core functional specifications. The substitute maintains SPI interface compatibility, 12-bit resolution, and buffered voltage output architecture.

Parameter Comparison

Engineering Selection Recommendations

The LTC1453CS8#PBF is a direct functional substitute for the obsolete TLV5636CDR. Both devices are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The substitute maintains active product status with Analog Devices Inc., ensuring long-term availability and supply chain stability.

The LTC1453CS8#PBF operates across an extended supply voltage range (2.7V ~ 5.5V) compared to the original part's discrete voltage levels, providing greater design flexibility. Both devices share identical 8-SOIC packaging and surface mount characteristics, enabling direct PCB layout compatibility without redesign.

Frequently Asked Questions (FAQ)

Q: Can the LTC1453CS8#PBF replace the TLV5636CDR in existing designs?

A: Yes. Both devices feature 12-bit resolution, SPI interface, buffered voltage output, and identical 8-SOIC packaging. Pin-for-pin compatibility is maintained, allowing direct substitution without PCB modifications.

Q: What are the differences in settling time between these parts?

A: The TLV5636CDR specifies 7µs settling time, while the LTC1453CS8#PBF specifies 14µs typical settling time. Applications requiring faster settling performance should evaluate timing margins in their specific signal chain.

Q: Are there differences in linearity specifications?

A: The TLV5636CDR specifies INL/DNL of ±2 and ±0.5 LSB respectively. The LTC1453CS8#PBF specifies ±4 and ±0.5 LSB maximum. Both devices meet 12-bit DAC linearity standards; applications with stringent linearity requirements should confirm compatibility with system specifications.

Q: What is the difference between String DAC and R-2R architecture?

A: The TLV5636CDR uses String DAC architecture while the LTC1453CS8#PBF uses R-2R architecture. Both architectures deliver 12-bit resolution with buffered voltage output. Architecture differences do not affect functional substitution for standard DAC applications.

Q: Is the extended supply voltage range of the LTC1453CS8#PBF a compatibility concern?

A: No. The LTC1453CS8#PBF's 2.7V ~ 5.5V supply range encompasses the TLV5636CDR's operating range. Designs operating within the original part's voltage specifications will function identically with the substitute.

Q: Are both parts available in the same packaging?

A: Yes. Both the TLV5636CDR and LTC1453CS8#PBF are housed in 8-SOIC (0.154", 3.90mm width) surface mount packages with identical pinouts and mechanical dimensions.
