TLC2272CPS Equivalent & Substitute Parts

Part Overview

The TLC2272CPS is a CMOS operational amplifier featuring dual circuits with rail-to-rail output capability in an 8-SOIC surface mount package. This device is classified as obsolete, which necessitates identification of active equivalent components for continued system design and production support. The TLC2272CPS maintains specific electrical characteristics including a 2.25 MHz gain bandwidth product, 3.6 V/µs slew rate, and operates across a 4.4 V to 16 V supply voltage range. Locating functionally equivalent active alternatives ensures design continuity and supply chain reliability.

Substitute Part Grouping Explanation

Substitution of the TLC2272CPS is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute relationship is established based on the following criteria:

Electrical Parameter Equivalence:

• Amplifier topology (CMOS)
• Dual-circuit configuration (2 circuits)
• Rail-to-rail output capability
• Slew rate (3.6 V/µs)
• Gain bandwidth product (2.25 MHz)
• Input bias current (1 pA)
• Input offset voltage (300 µV)
• Supply current per channel (2.4 mA)
• Output current per channel (50 mA)
• Supply voltage range (4.4 V to 16 V minimum and maximum)
• Operating temperature range (0°C to 70°C)

Mechanical & Packaging Equivalence:

• Surface mount technology
• 8-SOIC package with 0.209" width and 5.30 mm width specification
• Pin-compatible configuration

Compliance & Regulatory Equivalence:

• RoHS3 compliance
• Moisture sensitivity level 1
• REACH unaffected status

The TLC2272CPSR is identified as the manufacturer-recommended substitute, maintaining identical electrical specifications while differing only in packaging format (Cut Tape and Digi-Reel versus Tube).

Parameter Comparison

Engineering Selection Recommendations

The TLC2272CPSR is the direct equivalent substitute for the obsolete TLC2272CPS. Both components are manufactured by Texas Instruments and share identical electrical and mechanical specifications across all critical parameters. The primary distinction is product status: the TLC2272CPS is obsolete, while the TLC2272CPSR maintains active production status.

Selection of the TLC2272CPSR is supported by:

• Complete electrical parameter equivalence with the original TLC2272CPS
• Identical 8-SOIC surface mount package configuration ensuring pin-for-pin compatibility
• Active product status ensuring continued availability and supply chain support
• Maintained RoHS3 compliance and regulatory certifications
• Identical operating temperature range and environmental specifications

The packaging format difference (Tube versus Cut Tape and Digi-Reel) does not affect functional performance or circuit compatibility. Component selection should be based on procurement and assembly requirements.

Frequently Asked Questions (FAQ)

Q: Can the TLC2272CPSR be used as a direct replacement for the TLC2272CPS in existing designs?
