Product details
Overview
TLC272CPWRG4 from Texas Instruments is a precision dual CMOS operational amplifier optimized for single-supply operation, featuring 10 mV max input offset voltage (25°C), 10.8 nV/√Hz input voltage noise at 1 kHz, and rail-to-rail output swing down to the negative rail. It operates from 3 V to 16 V over 0°C to 70°C and delivers 4.5 MHz unity-gain bandwidth with 0.5 V/μs slew rate - enabling high-fidelity signal conditioning in battery-powered sensor interfaces and portable instrumentation.
For engineers reviewing the TLC272CPWRG4 datasheet, TLC272CPWRG4 pinout, TLC272CPWRG4 application, or TLC272CPWRG4 equivalent, key selection criteria include input offset voltage grade (C-suffix = 10 mV), TSSOP-8 package compatibility with space-constrained PCB layouts, single-supply common-mode range extending below ground, and low bias current (<60 pA) critical for high-impedance transducer amplification.
Technical Context
The TLC272CPWRG4 uses a polysilicon-gate CMOS process to achieve ultra-high input impedance (>10¹² Ω) and sub-picoampere input bias current, minimizing loading on high-Z sources like piezoelectric sensors and pH electrodes. Its input stage supports common-mode voltages down to –0.1 V (at VDD = 5 V), enabling true single-supply operation without level-shifting circuitry.
Internally, it integrates ESD protection and latch-up immunity, with dual amplifiers sharing a single 3–16 V supply. The device exhibits 65–80 dB common-mode rejection and 65–120 dB supply-voltage rejection across temperature, ensuring stable performance in noisy industrial environments where supply ripple and ground bounce are present.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | 10 mV max at 25°C - defines DC accuracy limit in precision gain stages and sensor front-ends |
| Supply Voltage Range | 3 V to 16 V - supports direct interface with 3.3 V, 5 V, and 12 V logic/system rails |
| Unity-Gain Bandwidth | 4.5 MHz - enables stable closed-loop operation up to ~100 kHz with moderate gain |
| Slew Rate | 0.5 V/μs - sufficient for audio-band signals and slow control loops; limits large-signal settling |
| Input Voltage Noise | 10.8 nV/√Hz at 1 kHz - dominates total noise in medium-impedance circuits (≤50 kΩ) |
| Common-Mode Input Range | Extends to –0.1 V below negative rail - eliminates need for negative supply in single-ended sensor buffering |
| Output Swing | Includes negative rail (VOL ≤ 50 mV) - preserves full dynamic range when referenced to ground |
Pinout & Package
The TLC272CPWRG4 is housed in a 8-pin TSSOP (PW) package measuring 3 mm × 6.4 mm, with exposed thermal pad (non-electrical), gull-wing leads, and RoHS-compliant matte-tin lead finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (A) | High-impedance node for feedback network connection; accepts signals down to –0.1 V |
| 2 | Non-Inverting Input (A) | High-Z input for reference or sensor signal; bias current <60 pA minimizes leakage error |
| 3 | Output (A) | Capable of sourcing/sinking ±30 mA; swings to within 50 mV of negative rail |
| 4 | Negative Supply (V–) | Ground reference for single-supply use; must be connected even when V– = 0 V |
| 5 | Non-Inverting Input (B) | Independent second channel input; identical specs to Pin 2 |
| 6 | Inverting Input (B) | Second channel inverting input; supports dual-channel signal processing in one footprint |
| 7 | Output (B) | Second independent output; shares same supply pins but electrically isolated from Channel A |
| 8 | Positive Supply (V+) | Accepts 3–16 V; internal regulation not provided - external decoupling required |
Key Features
| Feature | Design Value |
|---|---|
| Single-supply optimized input stage | Common-mode range extends below negative rail (–0.1 V), eliminating need for dual supplies in ground-referenced systems |
| Ultra-low input bias current | <60 pA typical at 25°C - enables use with >1 MΩ source impedances without significant DC error |
| Rail-to-rail output swing | VOL ≤ 50 mV at negative rail ensures maximum usable output voltage range in 3.3 V or 5 V systems |
| Low 1/f noise corner | 10.8 nV/√Hz at 1 kHz with minimal low-frequency drift - suitable for DC-coupled precision measurement |
| ESD protection circuitry | Integrated protection per JEDEC JS-001 (±2 kV HBM) - reduces risk of handling damage during assembly |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV272IDR | Lower VIO (2 mV max), lower supply current (1.25 mA typ), but narrower supply range (2.7–16 V) and no extended temp option | Better DC accuracy for high-precision metrology; less suited for wide-temp industrial use | Choose TLV272IDR when VIO < 2 mV is mandatory and operating temperature stays within 0°C–70°C |
| LMV358IDR | Higher VIO (7 mV max), rail-to-rail input/output, but higher noise (40 nV/√Hz) and lower GBW (1 MHz) | Cost-optimized for consumer electronics; insufficient noise performance for sensor front-ends | Choose LMV358IDR only for non-critical, low-bandwidth, cost-sensitive applications where noise and offset are secondary |
Compared with TLV272IDR and LMV358IDR, the TLC272CPWRG4 offers superior noise performance and wider temperature capability than the TLV272IDR, while delivering significantly better DC precision and bandwidth than the LMV358IDR - making it the optimal choice for industrial and medical signal chains requiring balanced accuracy, speed, and ruggedness.

FAQ
What is the maximum input offset voltage specification for TLC272CPWRG4 at 25°C?
The TLC272CPWRG4 has a maximum input offset voltage of 10 mV at 25°C, as specified in the Electrical Characteristics table for the C-suffix grade under VDD = 5 V conditions. This value applies across the full operating temperature range (0°C to 70°C), with a worst-case of 12 mV. The TLC272CPWRG4 is part of the standard-grade TLC272 family, distinct from the tighter-tolerance TLC272AC (5 mV max) and TLC272BC (2 mV max) variants.
Does TLC272CPWRG4 support true single-supply operation with inputs referenced to ground?
Yes, the TLC272CPWRG4 supports true single-supply operation: its common-mode input voltage range extends to –0.1 V below the negative rail (typically ground), and its output swings to within 50 mV of the negative rail. This allows direct interfacing with ground-referenced sensors and eliminates the need for level-shifting circuitry or dual supplies - a core design feature confirmed in Section 6.1.1 of the datasheet.
What is the unity-gain bandwidth and slew rate of TLC272CPWRG4, and how do they affect small-signal response?
The TLC272CPWRG4 has a unity-gain bandwidth of 4.5 MHz and a slew rate of 0.5 V/μs. These values define its small-signal frequency response and large-signal settling behavior: the 4.5 MHz GBW supports stable closed-loop gains up to ~100 kHz at moderate gain, while the 0.5 V/μs slew rate limits full-scale step response time to ~10 μs for a 5 V output swing - sufficient for audio and control-loop applications but not high-speed data acquisition. Both parameters are measured at VDD = 5 V, TA = 25°C.
Can TLC272CPWRG4 be used in automotive applications requiring operation from –40°C to 125°C?
No, the TLC272CPWRG4 is rated for 0°C to 70°C operation (C-suffix grade). For automotive applications requiring –40°C to 125°C, TI offers the TLC272IPWR (I-suffix) variant, which is specified from –40°C to 85°C - still short of 125°C. The TLC272CPWRG4 itself is not qualified for extended temperature operation; using it outside its rated range may result in parametric shift or functional failure, and TI does not guarantee performance beyond 70°C.
What package type and dimensions does TLC272CPWRG4 use, and is it compatible with standard TSSOP-8 footprints?
The TLC272CPWRG4 uses a PW (TSSOP-8) package measuring 3.0 mm × 6.4 mm with 0.65 mm lead pitch. It is fully compatible with industry-standard TSSOP-8 footprints and reflow profiles. The "G4" suffix denotes green (halogen-free) packaging and tape-and-reel delivery - consistent with TI's RoHS-compliant manufacturing standards. Mechanical details are documented in Section 9 of the SLOS091F datasheet.
