Product details
Overview
TLC2272IPW from Texas Instruments is a dual rail-to-rail output operational amplifier in TSSOP-8 package, delivering 2.2-MHz gain-bandwidth, 3.6-V/μs slew rate, 9 nV/√Hz input voltage noise at 1 kHz, 1-pA typical input bias current, and ±5-V supply operation with output swing to both rails. It serves precision signal conditioning in transducer interfaces and battery-powered monitoring systems.
For engineers reviewing the TLC2272IPW datasheet, TLC2272IPW pinout, TLC2272IPW application, or TLC2272IPW equivalent, key selection factors include rail-to-rail output swing under ±5-V operation, low 1-pA input bias current for high-impedance source interfacing, 950-μV maximum input offset voltage (A-grade), 2.2-MHz bandwidth for moderate-speed closed-loop designs, and TSSOP-8 thermal performance with RθJA = 175.8°C/W.
Technical Context
The TLC2272IPW uses Advanced LinCMOS process technology to achieve rail-to-rail output swing while maintaining low input bias current and low noise. Its input stage operates with common-mode voltage range extending to the negative rail, enabling single-supply sensor front-end configurations without level-shifting circuitry.
It features fully specified AC and DC performance across ±2.2 V to ±8 V supply ranges and −40°C to +125°C temperature range (I-level grade). The device exhibits 75-dB CMRR and 95-dB PSRR at 25°C, supporting stable operation in noisy industrial environments where supply rejection and common-mode immunity are critical.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual rail-to-rail operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLC2272CDR | SOIC-8 package (3.91 mm × 4.90 mm); higher RθJA (115.6°C/W); same electrical specs and pinout | Preferred for through-hole prototyping or legacy PCBs with SOIC footprints; less compact than TSSOP | Select TLC2272CDR when board space allows larger footprint and thermal margin exceeds 175.8°C/W requirement |
| TLV2432IDR | Higher output drive (±30 mA), wider input voltage range (beyond rails), but higher input bias current (100 pA) and noise (18 nV/√Hz) | Better suited for driving heavy capacitive loads or rail-overdrive sensor interfaces; trades precision for robustness | Choose TLV2432IDR when driving >1000-pF loads or requiring input overvoltage tolerance beyond ±0.3 V of rails |
Compared with TLC2272CDR and TLV2432IDR, the TLC2272IPW provides optimal balance of ultra-low input bias current, low noise, and compact TSSOP packaging-making it ideal for space-constrained, high-impedance sensor nodes where thermal resistance is managed via PCB copper area.

FAQ
What is the maximum supply voltage range supported by the TLC2272IPW?
The TLC2272IPW supports a total supply voltage range of ±2.2 V to ±8 V (i.e., 4.4 V to 16 V across VDD+ and VDD−/GND). Absolute maximum ratings specify ±8 V on each supply rail. Operation at ±5 V is fully characterized with 2.25-MHz gain-bandwidth and 3.6-V/μs slew rate, making it suitable for standard dual-rail industrial systems.
Does the TLC2272IPW have rail-to-rail input capability?
No, the TLC2272IPW does not feature rail-to-rail input. Its common-mode input voltage range extends to the negative rail (VDD−/GND) but stops 1.5 V below the positive rail (VDD+) under recommended operating conditions. At ±5 V supply, VICR spans −5 V to +3.5 V. This design enables ground-referenced sensor use but requires input signal limiting above VDD+ −1.5 V.
What is the input offset voltage specification for the TLC2272IPW?
The TLC2272IPW is part of the TLC2272A grade, with a maximum input offset voltage of 950 μV at TA = 25°C and full-range maximum of 1500 μV across −40°C to +125°C. Typical value is 300 μV. This specification applies directly to the TLC2272IPW device and is verified per TI's SLOS190H datasheet Section 6.5 and 6.6.
Can the TLC2272IPW drive a 10-kΩ load while maintaining rail-to-rail output swing?
Yes, the TLC2272IPW delivers rail-to-rail output swing into 10-kΩ loads. At ±5 V supply and IO = ±20 μA, VOH = 4.99 V and VOL = −4.99 V. Even at ±1 mA load, output remains within 4.25 V to −4.25 V - preserving >85% of full rail span. This performance is confirmed in the "Maximum Peak-to-Peak Output Voltage vs Supply Voltage" graph and electrical tables of the datasheet.
Is the TLC2272IPW pin-compatible with other packages in the TLC2272 family?
Yes, the TLC2272IPW (TSSOP-8) shares identical pinout and function mapping with the SOIC-8 (TLC2272CDR), PDIP-8 (TLC2272P), and CDIP-8 (TLC2272J) variants. Pin 1 is OUT A, Pin 2 is IN− A, Pin 3 is IN+ A, Pin 4 is VDD−/GND, Pin 5 is IN+ B, Pin 6 is IN− B, Pin 7 is OUT B, and Pin 8 is VDD+. This allows drop-in replacement across packages when thermal and board-space constraints permit.
