Product details
Overview
TLC272CPWR from Texas Instruments is a precision dual CMOS operational amplifier optimized for single-supply operation, featuring 10 mV max input offset voltage (C-grade), 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 - enabling high-fidelity signal conditioning in battery-powered sensor front-ends and industrial analog interfaces.
For engineers reviewing the TLC272CPWR datasheet, TLC272CPWR pinout, TLC272CPWR application, or TLC272CPWR equivalent, key selection criteria include its low-input-bias-current (≤60 pA typ), wide common-mode input range extending below ground, and compatibility with 3 V–16 V single-rail supplies in instrumentation, data acquisition, and portable medical devices.
Technical Context
The TLC272CPWR uses a polysilicon-gate CMOS process to achieve ultra-high input impedance (>10¹² Ω) and low input bias current (10–60 pA), minimizing loading on high-impedance 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, and its output stage drives ±30 mA while maintaining low-level output voltage ≤50 mV (IOL = 0) - critical for interfacing with low-voltage logic and ADC reference buffers. The device exhibits 65–80 dB CMRR and 65–120 dB PSRR across temperature, supporting stable performance in noisy industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | 10 mV max (C-grade, 25°C); enables accurate DC-coupled amplification in 12-bit systems without trimming. |
| Supply Voltage Range | 3 V to 16 V (0°C to 70°C); supports direct interface with 3.3 V/5 V logic and legacy 12 V industrial rails. |
| Unity-Gain Bandwidth | 4.5 MHz (25°C); sufficient for anti-aliasing filters and active sensor signal conditioning up to ~200 kHz. |
| Input Voltage Noise | 10.8 nV/√Hz at 1 kHz; lower than bipolar op-amps above 50 kΩ source impedances, reducing thermal noise dominance. |
| Common-Mode Input Range | Extends to –0.1 V below negative rail (VDD = 5 V); allows ground-referenced inputs in single-supply configurations. |
| Slew Rate | 0.5 V/μs (unity gain, 100 mVpp); supports moderate-speed step response without overshoot in closed-loop gain ≥10. |
| Output Swing | Within 50 mV of negative rail and within 50 mV of positive rail (VDD = 5 V); preserves dynamic range for low-voltage ADC drivers. |
Pinout & Package
TLC272CPWR is housed in an 8-pin TSSOP (PW) package measuring 3 mm × 6.4 mm, with exposed pad for thermal enhancement and surface-mount compatibility.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (Amplifier A) | High-impedance node accepting differential signal; requires guard ring routing to suppress PCB leakage. |
| 2 | Non-Inverting Input (Amplifier A) | Accepts reference or sensor signal; common-mode range includes negative rail for ground-referenced sources. |
| 3 | Output (Amplifier A) | Capable of sourcing/sinking ±30 mA; output swing extends to within 50 mV of supply rails. |
| 4 | Negative Supply (GND) | Reference for single-supply operation; also serves as return path for both amplifiers' bias currents. |
| 5 | Non-Inverting Input (Amplifier B) | Independent input for second channel; identical specs to Pin 2, enabling dual-channel signal processing. |
| 6 | Inverting Input (Amplifier B) | Matches Pin 1 functionality; supports matched dual configurations like differential receivers or dual-filter stages. |
| 7 | Output (Amplifier B) | Electrically isolated from Pin 3; allows independent gain/feedback networks per channel. |
| 8 | Positive Supply (VDD) | Accepts 3–16 V; internal regulation ensures stable biasing across full supply range and temperature. |
Key Features
| Feature | Design Value |
|---|---|
| Single-supply operation | Operates from 3 V to 16 V with input common-mode range extending below GND and rail-to-rail output swing - eliminates need for split supplies in portable and industrial systems. |
| Low input bias current | 10–60 pA typical (25°C); enables use with high-impedance sources (e.g., photodiodes, pH probes) without significant DC error. |
| Low input voltage noise | 10.8 nV/√Hz at 1 kHz; outperforms bipolar op-amps in medium-to-high-impedance circuits (>50 kΩ), improving SNR in sensor interfaces. |
| ESD protection | Integrated circuitry withstands human-body-model ESD events per JEDEC JS-001; reduces field failure risk during handling and assembly. |
| Latch-up immunity | Designed-in robustness against parasitic SCR activation; ensures reliable operation under transient overvoltage or supply sequencing stress. |

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 |
|---|---|---|---|
| TLV272IPWR | Lower VIO (2 mV max), lower supply current (1.25 mA typ), but narrower supply range (2.7–16 V) and reduced CMRR (60 dB min). | Better for ultra-low-offset, low-power portable designs; less suitable for noisy industrial environments requiring high CMRR. | Select TLV272IPWR when offset-critical 16-bit+ systems demand <2 mV VIO and supply current <1.5 mA. |
| OPA2333AIPWR | Zero-drift architecture, 12 µV max VIO, 0.02 µV/°C drift, but higher cost and 1.8–5.5 V supply limit. | Ideal for precision weigh scales and medical diagnostics needing sub-µV/°C drift; incompatible with 12 V rails. | Choose OPA2333AIPWR only when long-term DC stability and <1 µV/°C drift outweigh supply flexibility and cost constraints. |
Compared with TLV272IPWR and OPA2333AIPWR, the TLC272CPWR offers broader supply voltage support (3–16 V), proven latch-up immunity, and balanced trade-offs between offset, noise, and cost - making it optimal for industrial analog I/O where reliability and voltage flexibility are prioritized over ultra-low drift.

FAQ
What is the maximum input offset voltage specification for TLC272CPWR?
The TLC272CPWR has a maximum input offset voltage of 10 mV at 25°C, specified for the C-grade (commercial temperature range: 0°C to 70°C). This value increases to 12 mV over the full operating temperature range. The parameter is measured with VO = 1.4 V, RS = 50 Ω, VIC = 0 V, and RL = 10 kΩ - consistent with standard op-amp test conditions defined in the SLOS091F datasheet.
Does TLC272CPWR support true single-supply operation with inputs referenced to ground?
Yes, the TLC272CPWR supports true single-supply operation with inputs referenced to ground. Its common-mode input voltage range extends to –0.1 V below the negative rail (GND) at VDD = 5 V, and its output swings within 50 mV of GND. This allows direct connection of ground-referenced sensors without external level-shifting circuitry - a core design feature confirmed in Section 6.1.1 of the TLC272 datasheet.
What is the unity-gain bandwidth and slew rate of TLC272CPWR?
The TLC272CPWR has a unity-gain bandwidth of 4.5 MHz and a slew rate of 0.5 V/μs (measured at unity gain, RL = 10 kΩ, CL = 20 pF, VIPP = 100 mV). These values are specified at 25°C with VDD = 5 V and define the device's small-signal speed and large-signal transient response - critical for active filter design and step-response fidelity in signal conditioning circuits.
Can TLC272CPWR be used in automotive under-hood applications?
The TLC272CPWR (C-suffix) is rated for 0°C to 70°C and is not qualified for under-hood use. However, the pin-compatible TLC272IPWR (I-suffix) operates from –40°C to 85°C and shares identical electrical specifications - including 10 mV max VIO and 4.5 MHz GBW - making it the appropriate variant for automotive cabin or engine-control peripheral applications requiring extended temperature support.
How does the input bias current of TLC272CPWR compare to bipolar op-amps?
The TLC272CPWR exhibits input bias current of 10–60 pA typical at 25°C - over six orders of magnitude lower than typical bipolar op-amps (e.g., LM358: ~45 nA). This enables high-impedance sensor interfacing (e.g., pH electrodes, photodiodes) without significant DC error, and reduces Johnson noise contribution in circuits with source impedances >50 kΩ - a key advantage confirmed in Section 6.1.2 and Table 4.3 of the datasheet.
