Product details
Overview
TLC2272IPWRG4 from Texas Instruments is a dual rail-to-rail output operational amplifier optimized for precision, low-noise signal conditioning in single- or split-supply systems. It delivers 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 rail-to-rail output swing - enabling high-fidelity interfacing with ADCs in battery-powered sensor front-ends.
For engineers reviewing the TLC2272IPWRG4 datasheet, TLC2272IPWRG4 pinout, TLC2272IPWRG4 application, or TLC2272IPWRG4 equivalent, key selection criteria include its ±2.2 V to ±8 V supply range, 950 µV max input offset voltage (A-grade), low 2.4–3 mA supply current, and TSSOP-8 package compatibility with space-constrained industrial and portable designs.
Technical Context
The TLC2272IPWRG4 employs advanced LinCMOS process technology to achieve rail-to-rail output swing while maintaining low input bias current and low noise - distinguishing it from bipolar or standard CMOS op-amps. Its common-mode input voltage range extends to the negative rail, supporting ground-sensing configurations in single-supply applications.
It operates across ±2.2 V to ±8 V supplies (or 4.4 V to 16 V single-supply) and is fully characterized at both 5 V and ±5 V. The device features 10¹² Ω input resistance, 75–80 dB CMRR, and 80–95 dB PSRR, making it suitable for high-impedance transducer interfaces where DC accuracy and AC fidelity are jointly critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | ±2.2 V to ±8 V (or 4.4 V to 16 V single-supply); supports wide industrial and automotive battery-derived rails |
| Gain-Bandwidth Product | 2.25 MHz typical at ±5 V; enables stable unity-gain buffering and moderate-speed filtering up to ~200 kHz |
| Slew Rate | 3.6 V/µs typical; supports clean 1-Vpp signals up to ~570 kHz without slew-induced distortion |
| Input Offset Voltage | ≤950 µV max (TLC2272A grade); ensures ≤0.02% error in 5-V full-scale precision measurement paths |
| Input Bias Current | 1 pA typical; minimizes voltage drop across >100-MΩ source impedances (e.g., piezoelectric sensors) |
| Voltage Noise Density | 9 nV/√Hz at 1 kHz; 5× lower than TLC272, critical for low-level analog signal integrity |
| Common-Mode Input Range | Includes negative rail (down to VDD−); enables direct ground-referenced sensor amplification |
Pinout & Package
TLC2272IPWRG4 is housed in an 8-pin TSSOP package (4.40 mm × 3.00 mm body size), optimized for automated assembly and thermal performance in compact PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplified output of Channel 1; rail-to-rail swing supports full dynamic range into ADC reference or downstream stage |
| 2 | IN− A | Inverting input of Channel 1; high 10¹² Ω impedance preserves signal integrity from high-Z sources |
| 3 | IN+ A | Non-inverting input of Channel 1; common-mode range includes VDD−, enabling true ground-sensing |
| 4 | VDD−/GND | Negative supply or ground reference; shared return for both channels and internal biasing |
| 5 | IN+ B | Non-inverting input of Channel 2; independent dual-channel operation allows differential pair or dual-path signal processing |
| 6 | IN− B | Inverting input of Channel 2; matched input characteristics ensure channel-to-channel consistency |
| 7 | OUT B | Amplified output of Channel 2; identical AC/DC specs to Channel 1 enable symmetrical design reuse |
| 8 | VDD+ | Positive supply rail; accepts up to +8 V (or +16 V single-supply), defining upper output limit and headroom |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Delivers full supply-voltage dynamic range (e.g., 0 V to 5 V on 5-V single supply), maximizing ADC utilization and SNR |
| Low 1-pA input bias current | Enables accurate amplification of microamp-level currents and high-impedance (>1 GΩ) sensor outputs without loading error |
| 9 nV/√Hz input voltage noise | Reduces integrated noise floor in 10 Hz–100 kHz bandwidths, critical for ECG, strain gauge, and microphone preamplifiers |
| Specified for single- and split-supply operation | Eliminates need for separate design variants - same schematic works for 5-V logic systems or ±5-V instrumentation rails |
| 2.2-MHz bandwidth with 3.6-V/µs slew rate | Supports stable closed-loop gain ≥10 up to ~200 kHz and fast settling (<3.2 µs to 0.01%) for multiplexed data acquisition |

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; higher thermal resistance (115.6°C/W vs. 175.8°C/W for TSSOP); identical electrical specs | Preferred for through-hole prototyping or legacy board compatibility; less suited for high-density SMT layouts | Select when mechanical mounting or hand-soldering is required; avoid if thermal dissipation or board area is constrained. |
| TLV2432IDR | Higher output drive (±30 mA vs. ±50 mA), wider input voltage range (rail-to-rail input), but higher 22 nV/√Hz noise and 3.5-mA supply current | Better for driving heavy capacitive loads or rail-to-rail input requirements; trades noise and power for drive strength | Choose when driving >1000-pF loads or requiring input beyond supply rails; not recommended for low-noise sensor front-ends. |
Compared with TLC2272CDR and TLV2432IDR, the TLC2272IPWRG4 provides optimal balance of ultra-low noise, micropower operation, and TSSOP-8 footprint - making it superior for space- and battery-limited precision analog signal chains where input bias current and voltage noise dominate error budgets.

FAQ
What is the maximum supply voltage rating for the TLC2272IPWRG4?
The TLC2272IPWRG4 has an absolute maximum supply voltage rating of ±8 V (or 16 V single-supply). Operation beyond this risks permanent damage. Recommended operating range is ±2.2 V to ±8 V, with full electrical specifications guaranteed across this span at temperatures from –40°C to +125°C for I-grade parts.
Does the TLC2272IPWRG4 support true rail-to-rail input?
No - the TLC2272IPWRG4 features rail-to-rail *output* swing only. Its common-mode input voltage range extends to the negative rail (VDD−) but stops 1.5 V below the positive rail (VDD+ − 1.5 V), as specified in the Recommended Operating Conditions table. For rail-to-rail input capability, consider TI's TLV2432 or OPA333 families.
What is the input offset voltage specification for the TLC2272IPWRG4?
The TLC2272IPWRG4 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. This is tighter than the standard TLC2272 (3000 µV max), making it suitable for precision DC-coupled applications like weigh scales and temperature measurement bridges.
Can the TLC2272IPWRG4 drive capacitive loads directly?
The TLC2272IPWRG4 is stable with up to 100 pF capacitive load under unity-gain conditions, as verified in the datasheet's phase margin (52°) and gain margin (10 dB) tests. Driving larger capacitive loads (e.g., >500 pF) requires isolation resistance or external compensation to prevent peaking or oscillation - consult TI's Application Report SLOA061 for layout and stability guidelines.
Is the TLC2272IPWRG4 RoHS-compliant and lead-free?
Yes - the "G4" suffix in TLC2272IPWRG4 indicates RoHS-compliant, lead-free packaging per JEDEC J-STD-020 moisture sensitivity level 2a (MSL-2a), with peak reflow temperature of 260°C. The device meets TI's green chemistry standards and is suitable for modern lead-free manufacturing processes without exemption.
