Product details
Overview
TLC272IPG4 from Texas Instruments is a precision dual CMOS operational amplifier optimized for single-supply operation, featuring 10 mV max input offset voltage (I-suffix), low input bias current (≤60 pA), 10.8 nV/√Hz input voltage noise at 1 kHz, and rail-to-rail output swing down to the negative rail - enabling use in battery-powered sensor signal conditioning and industrial analog front-ends.
For engineers reviewing the TLC272IPG4 datasheet, TLC272IPG4 pinout, TLC272IPG4 application, or TLC272IPG4 equivalent, key selection criteria include its guaranteed 4 V to 16 V supply range over –40°C to +85°C, high CMRR (65–85 dB), and compatibility with high-impedance sources (>10¹² Ω) in low-power instrumentation designs.
Technical Context
The TLC272IPG4 employs a polysilicon-gate CMOS process delivering ultra-low input bias current and stable offset voltage drift (0.3 µV/°C), making it suitable for precision DC-coupled amplification where thermal stability and minimal loading of high-Z sensors are critical. Its input stage supports common-mode voltages extending below ground, and its output drives to within 50 mV of the negative rail under load.
Designed for single-supply systems, the device maintains full functionality across 4 V to 16 V operation and achieves 4.5 MHz unity-gain bandwidth with 0.5 V/µs slew rate - balancing speed and precision without requiring split supplies or level-shifting circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 4 V to 16 V - enables direct interface with 5 V and 12 V industrial logic rails and battery-powered systems without regulation overhead. |
| Input Offset Voltage (max) | 10 mV at 25°C - defines worst-case DC error in precision gain stages; specified for I-suffix grade over full temperature range. |
| Input Bias Current (max) | 60 pA at 25°C - allows use with >1 MΩ source impedances without significant voltage drop or drift-induced errors. |
| Input Voltage Noise | 10.8 nV/√Hz at 1 kHz - supports low-noise amplification of microvolt-level sensor outputs (e.g., thermocouples, strain gauges). |
| Common-Mode Input Range | –0.1 V to 8.5 V at VDD = 10 V - includes ground reference, enabling true single-supply operation with AC-coupled or biased inputs. |
| Output Swing (low) | 0 to 50 mV above negative rail - ensures full dynamic range utilization when driving ADCs or comparators referenced to ground. |
| CMRR | 65–85 dB - rejects power supply ripple and shared-noise coupling in mixed-signal PCB layouts. |
Pinout & Package
The TLC272IPG4 is housed in an 8-pin PDIP (Plastic Dual Inline Package) measuring 9.81 mm × 9.43 mm, with through-hole mounting and industry-standard lead spacing for legacy board compatibility and manual prototyping.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting input (Amplifier A) | High-impedance node accepting differential signal; requires guard ring layout for leakage-sensitive applications. |
| 2 | Non-inverting input (Amplifier A) | Accepts reference or sensor signal; common-mode range extends below ground for true single-supply biasing. |
| 3 | Output (Amplifier A) | Capable of sourcing/sinking ±30 mA; swings to within 50 mV of negative rail and 0.05 V below positive rail. |
| 4 | Negative supply (V−) | Connected to ground in single-supply mode; must be decoupled with 0.1 µF ceramic capacitor near pin. |
| 5 | Non-inverting input (Amplifier B) | Independent second channel input; identical electrical specs to Pin 2; unused channel should be configured as unity-gain follower. |
| 6 | Inverting input (Amplifier B) | Matches Pin 1 performance; supports independent signal path or feedback configuration for dual-channel filtering. |
| 7 | Output (Amplifier B) | Electrically isolated from Output A; shares same supply pins but requires individual load decoupling if driving reactive loads. |
| 8 | Positive supply (V+) | Accepts 4–16 V; total supply current ≤4.4 mA (two amps, –40°C); requires local 0.1 µF + 10 µF bulk decoupling. |
Key Features
| Feature | Design Value |
|---|---|
| Single-supply operation | Operates from 4 V to 16 V with input common-mode range including ground and output swing to negative rail - eliminates need for split supplies in portable and industrial systems. |
| Ultra-low input bias current | ≤60 pA typical at 25°C - enables high-precision amplification of signals from piezoelectric sensors, pH electrodes, and photodiode transimpedance stages without loading error. |
| Low input voltage noise | 10.8 nV/√Hz at 1 kHz - reduces integrated noise in bandwidth-limited sensor interfaces, improving SNR for sub-mV signal detection. |
| Latch-up immunity | Designed-in protection against destructive latch-up during overvoltage or ESD events - enhances reliability in unregulated or noisy power environments. |
| ESD protection circuitry | Integrated input protection per JEDEC JS-001 - withstands ≥2 kV HBM, reducing need for external TVS diodes in cost-sensitive designs. |

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 |
|---|---|---|---|
| TLV272IP | Lower supply current (1.25 mA vs 4.4 mA), reduced VIO (5 mV max), but narrower supply range (2.7–16 V) and no –40°C to +85°C guarantee for all parameters. | Better suited for ultra-low-power battery applications; less robust for industrial ambient extremes. | Select TLV272IP only when supply current <1.5 mA is mandatory and temperature range can be limited to 0°C–70°C. |
| OPA2333PA | Zero-drift architecture, 10 µV max VIO, 0.02 µV/°C drift, but higher cost and 1.8–5.5 V supply limit - incompatible with 12 V systems. | Required for µV-level DC accuracy in high-end medical or scientific instruments; not viable for 12 V industrial use. | Choose OPA2333PA only when sub-20 µV offset and <0.1 µV/°C drift are non-negotiable and supply is constrained to ≤5.5 V. |
Compared with TLV272IP and OPA2333PA, the TLC272IPG4 provides the broadest industrial temperature and supply voltage coverage (–40°C to +85°C, 4–16 V) while maintaining adequate precision (10 mV VIO) and ultra-low bias current - making it the optimal balance for cost-sensitive, ruggedized analog signal chains.

FAQ
What is the maximum operating temperature range for the TLC272IPG4?
The TLC272IPG4 is rated for operation from –40°C to +85°C, matching the I-suffix specification. This range is validated across all key parameters including input offset voltage, CMRR, and supply current - ensuring reliable performance in automotive under-hood and industrial control cabinet environments where ambient temperatures exceed standard commercial limits.
Does the TLC272IPG4 support true rail-to-rail input operation?
The TLC272IPG4 does not provide full rail-to-rail input; its common-mode input voltage range extends to –0.1 V (below ground) and up to VDD – 1.5 V at temperature extremes. At VDD = 10 V and TA = 25°C, the usable range is –0.1 V to 8.5 V. This "beyond-the-rail" negative input capability enables ground-referenced single-supply designs, but the upper limit remains 1.5 V below VDD.
Can the TLC272IPG4 drive capacitive loads directly?
The TLC272IPG4 is not unity-gain stable into large capacitive loads. Driving >20 pF directly may cause peaking or oscillation. For loads exceeding this, TI recommends adding a series resistor (typically 10–100 Ω) between the output and capacitance, or using a dedicated buffer stage - especially critical in ADC driver and filter applications where phase margin must exceed 60°.
How does the input offset voltage drift behave over temperature for the TLC272IPG4?
The TLC272IPG4 exhibits a guaranteed maximum input offset voltage temperature coefficient of 0.3 µV/°C over 25°C to 85°C. This low drift - enabled by TI's polysilicon-gate CMOS process - ensures predictable, linear offset variation across its full operating range, simplifying system-level calibration and improving long-term measurement stability in unattended equipment.
Is the TLC272IPG4 pin-compatible with other devices in the TLC27xx family?
Yes, the TLC272IPG4 shares identical 8-pin PDIP pinout with all TLC272x, TLC272Ax, TLC272Bx, and TLC277x variants in the P-package. This allows direct substitution within the same package footprint for different offset grades (e.g., upgrading from TLC272IPG4 to TLC277IPG4) without PCB redesign - provided supply and layout constraints remain compatible.
