TLC2272IPWR Equivalent & Substitute Parts

Part Overview

The TLC2272IPWR is a CMOS dual-channel operational amplifier manufactured by Texas Instruments, housed in an 8-TSSOP surface mount package. This device features rail-to-rail output capability and is designed for general-purpose analog signal processing applications requiring low power consumption and precision amplification. The part maintains Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when equivalent functional performance can be achieved within the specified electrical and mechanical parameter ranges, particularly when original inventory is unavailable or when alternative supply chain options are required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TLC2272IPWR is determined by strict alignment with the following critical parameters:

Package Compatibility: The substitute part must use the 8-TSSOP surface mount package with identical 0.173" (4.40mm) width specification to ensure PCB footprint compatibility without layout redesign.

Functional Architecture: The substitute must provide dual-channel (2 circuit) amplifier configuration with rail-to-rail output capability to maintain signal swing characteristics within the original design envelope.

Supply Voltage Range: The substitute must operate within or encompass the 4.4V to 16V supply span of the TLC2272IPWR. Parts with wider supply ranges are acceptable; parts with narrower ranges are not.

Temperature Rating: The substitute must support the -40°C to 125°C operating temperature range to ensure thermal compatibility across all specified environments.

Compliance Standards: The substitute must maintain RoHS3 compliance and MSL Level 1 rating to satisfy regulatory and manufacturing process requirements.

The NCS20072DTBR2G meets these substitution criteria through identical package geometry, dual-channel configuration, rail-to-rail output, and full compliance certification. The substitute operates across a wider supply voltage range (2.7V to 36V), which encompasses the TLC2272IPWR specification and provides additional design flexibility.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection Criteria:

The TLC2272IPWR remains the preferred component when original part availability is confirmed and supply chain continuity is established. Both the TLC2272IPWR and NCS20072DTBR2G maintain Active product status with identical RoHS3 compliance and MSL Level 1 ratings, ensuring regulatory and manufacturing process compatibility.

Substitution Conditions:

The NCS20072DTBR2G is a valid substitute when TLC2272IPWR inventory is depleted or lead times exceed project requirements. The substitute provides identical package geometry and dual-channel rail-to-rail architecture, enabling direct PCB placement without layout modification.

Supply Voltage Consideration:

The NCS20072DTBR2G operates across a wider supply voltage range (2.7V to 36V) compared to the TLC2272IPWR (4.4V to 16V). This expanded range does not create incompatibility; designs operating within the 4.4V to 16V window remain fully functional with the substitute part.

Performance Trade-offs:

The NCS20072DTBR2G exhibits lower supply current consumption (0.42mA versus 2.4mA across both channels), which may provide power efficiency benefits in battery-powered or low-power applications. The substitute demonstrates higher gain bandwidth product (3.2MHz versus 2.25MHz) and greater output current capability (65mA versus 50mA per channel). Input offset voltage is higher in the substitute (1.3mV versus 300µV), which may affect precision analog applications requiring sub-millivolt accuracy.

Compliance Verification:

Both parts satisfy ROHS3 compliance, REACH unaffected status, and EAR99 export classification. Moisture sensitivity Level 1 (Unlimited) applies to both devices, eliminating bake-out or desiccant storage requirements.

Frequently Asked Questions (FAQ)

Q: Can the NCS20072DTBR2G be used as a direct replacement for the TLC2272IPWR on existing PCBs?

A: Yes. Both parts use identical 8-TSSOP package geometry with 0.173" (4.40mm) width. The footprint, pin spacing, and mounting requirements are identical, allowing direct component substitution without PCB redesign or layout modification.

Q: What are the key electrical differences between these two parts?

A: The NCS20072DTBR2G provides lower supply current consumption (0.42mA versus 2.4mA), higher gain bandwidth product (3.2MHz versus 2.25MHz), and greater output current per channel (65mA versus 50mA). The TLC2272IPWR offers lower input offset voltage (300µV versus 1.3mV) and lower input bias current (1pA versus 5pA), making it more suitable for precision applications.

Q: Are there supply voltage compatibility issues when substituting the NCS20072DTBR2G?

A: No. The NCS20072DTBR2G operates across 2.7V to 36V, which fully encompasses the TLC2272IPWR specification of 4.4V to 16V. Designs operating within the original 4.4V to 16V range will function identically with the substitute part.

Q: Do both parts meet the same compliance and regulatory standards?

A: Yes. Both the TLC2272IPWR and NCS20072DTBR2G are RoHS3 compliant, REACH unaffected, and classified as EAR99 for export purposes. Both carry MSL Level 1 (Unlimited) moisture sensitivity rating and support the -40°C to 125°C operating temperature range.

Q: Which part should be selected for low-power applications?

A: The NCS20072DTBR2G is preferable for low-power designs due to significantly lower supply current consumption (0.42mA versus 2.4mA across both channels). This characteristic provides substantial power efficiency benefits in battery-powered or energy-constrained systems.

Q: Which part is better for precision analog signal processing?

A: The TLC2272IPWR is better suited for precision applications requiring low input offset voltage (300µV versus 1.3mV) and minimal input bias current (1pA versus 5pA). Applications with sub-millivolt accuracy requirements should prioritize the TLC2272IPWR.

Q: Can the substitute part handle higher output current demands?

A: Yes. The NCS20072DTBR2G provides 65mA per channel output current capability compared to 50mA for the TLC2272IPWR, offering 30% greater output drive capability for applications requiring higher load currents.

Q: Are there packaging or moisture sensitivity differences?

A: No. Both parts use 8-TSSOP surface mount packaging and carry identical MSL Level 1 (Unlimited) moisture sensitivity ratings. No special storage, handling, or bake-out procedures are required for either part.
