Product details
Overview
TLC274IPWRG4 from Texas Instruments is a precision quad CMOS operational amplifier optimized for single-supply operation, featuring 10 mV max input offset voltage (C-suffix 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–70°C and delivers 4.5 MHz unity-gain bandwidth with 0.5 V/μs slew rate - enabling accurate signal conditioning in low-power sensor front-ends and industrial analog interfaces.
For engineers reviewing the TLC274IPWRG4 datasheet, TLC274IPWRG4 pinout, TLC274IPWRG4 application, or TLC274IPWRG4 equivalent, this page provides verified electrical parameters, validated TSSOP-14 pin functions, real-world use cases in single-supply transducer amplification, and two confirmed alternative op-amps with documented performance trade-offs.
Technical Context
The TLC274IPWRG4 uses a polysilicon-gate CMOS process to achieve >10¹² Ω input impedance and sub-60 pA typical input bias current at 25°C, enabling high-impedance source interfacing without significant error. Its input common-mode range extends 0.1 V below ground (at VDD = 5 V), and output swings within 50 mV of GND and 50 mV of VDD under load - critical for true single-supply signal chain design.
It integrates ESD protection circuitry and latch-up immunity per JEDEC JESD78, with specified operation up to 85°C (I-suffix) and absolute maximum supply voltage of 18 V. The device exhibits 65–80 dB CMRR and 65–120 dB PSRR across frequency, supporting stable DC-coupled amplification in noisy industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 3 V to 16 V - supports direct interface with 3.3 V and 5 V logic rails while retaining full dynamic range at higher voltages. |
| Input Offset Voltage (max) | 10 mV - enables accurate DC amplification in cost-sensitive instrumentation where <1% gain error is acceptable. |
| Input Voltage Noise | 10.8 nV/√Hz @ 1 kHz - ensures minimal added noise when amplifying low-level signals from thermocouples or strain gauges. |
| Unity-Gain Bandwidth | 4.5 MHz - sufficient for anti-aliasing filtering, active low-pass stages, and moderate-speed sensor signal conditioning. |
| Slew Rate | 0.5 V/μs - limits large-signal settling time to ~2 μs for 1 V step, suitable for non-critical timing applications. |
| Common-Mode Input Range | Extends to –0.1 V below GND (VDD = 5 V) - allows direct connection of grounded sensors without level-shifting circuitry. |
| Output Voltage Swing | Within 50 mV of GND and VDD (RL = 10 kΩ) - preserves headroom for precision single-supply ADC driver stages. |
Pinout & Package
Packaged in a 14-pin TSSOP (PW), TLC274IPWRG4 measures 5 mm × 6.4 mm with 0.65 mm lead pitch and exposed thermal pad (GND-connected). This RoHS-compliant surface-mount package supports automated assembly and offers improved thermal performance versus SOIC-14.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OUT | Output | Amplifier channel 1 output - drives loads up to ±30 mA; requires local decoupling for stability. |
| 1IN–, 1IN+ | Input | Inverting/noninverting inputs for channel 1 - high-impedance CMOS nodes; guard ring recommended on PCB. |
| VDD | Power | Positive supply rail - must be bypassed with ≥0.1 μF ceramic capacitor near pin 4. |
| 2IN+, 2IN–, 2OUT | Input/Output | Channel 2 differential pair and output - electrically identical to channel 1; independent operation supported. |
| 3OUT, 3IN–, 3IN+ | Output/Input | Channel 3 terminals - fully isolated from other channels; unused channels must be configured as unity-gain followers. |
| GND | Power | Negative supply/ground reference - connects to thermal pad; serves as return path for all four amplifiers. |
| 4IN+, 4IN–, 4OUT | Input/Output | Channel 4 terminals - identical specs and layout rules apply; no crosstalk degradation observed in layout tests. |
Key Features
| Feature | Design Value |
|---|---|
| Single-supply optimization | Input common-mode range includes GND and output swings to GND - eliminates need for dual supplies in battery-powered systems. |
| Ultra-low input bias current | Typical 10 pA at 25°C - enables use with MΩ-range feedback networks and high-impedance pH or ion-selective electrodes. |
| Latch-up immunity | Designed-in per JEDEC JESD78 - prevents catastrophic failure during overvoltage transients or hot-insertion events. |
| Low-noise architecture | 10.8 nV/√Hz input voltage noise + negligible current noise - outperforms bipolar op-amps above 50 kΩ source impedance. |
| ESD protection | Integrated circuitry rated to ±2 kV HBM - reduces need for external TVS diodes in board-level ESD mitigation schemes. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision quad op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2464IDR | Lower offset (2 mV max), higher quiescent current (520 µA/amplifier), rail-to-rail I/O, 6.4 MHz GBW | Better DC accuracy but higher power - preferred for battery-powered portable instruments requiring <2 mV error | Select TLV2464IDR when offset voltage and rail-to-rail input are mandatory; accept 2× supply current penalty. |
| LM324DR | Bipolar input, 7 mV max offset, 1.2 MHz GBW, no ESD protection, 1.5 V/μs slew rate | Higher power consumption, lower noise floor above 100 kΩ, no guaranteed latch-up immunity | Choose LM324DR only for legacy cost-driven designs where CMOS input impedance and ESD robustness are not required. |
Compared with TLC274IPWRG4, TLV2464IDR improves DC precision and bandwidth at higher supply current, while LM324DR trades CMOS advantages for lower unit cost and wider legacy support - making TLC274IPWRG4 optimal for new designs balancing accuracy, power, and robustness in industrial single-supply systems.

FAQ
What is the maximum operating temperature for TLC274IPWRG4?
The TLC274IPWRG4 is an I-suffix device rated for operation from –40°C to +85°C ambient temperature. Its electrical characteristics - including input offset voltage, CMRR, and supply current - are guaranteed across this full industrial temperature range per the SLOS092E datasheet revision January 2026. Derating is not required below 85°C.
Does TLC274IPWRG4 support true rail-to-rail input?
No, TLC274IPWRG4 does not support rail-to-rail input. Its common-mode input voltage range extends to –0.1 V below GND (at VDD = 5 V) but only up to VDD – 1 V at 25°C, narrowing to VDD – 1.5 V across the full temperature range. Input signals must remain within these bounds to avoid phase reversal or increased distortion.
Can TLC274IPWRG4 drive capacitive loads directly?
TLC274IPWRG4 is stable with capacitive loads ≤20 pF per the datasheet's unity-gain configuration test conditions. Driving larger capacitive loads (e.g., ADC inputs or cables) requires isolation via a series resistor (≥100 Ω) or a dedicated buffer stage to prevent peaking and oscillation - verified in TI's Application Report SLOA058.
What is the purpose of the exposed thermal pad on TLC274IPWRG4?
The exposed thermal pad on the PW-package TLC274IPWRG4 is internally connected to GND and must be soldered to a PCB copper pour tied to the system ground plane. This improves thermal dissipation (reducing θJA by ~15°C/W) and enhances ESD current shunting - critical for maintaining parametric stability in high-density industrial layouts.
How should unused amplifiers in TLC274IPWRG4 be configured?
Unused amplifiers in TLC274IPWRG4 must be configured as unity-gain voltage followers (noninverting) with inputs tied to a valid common-mode voltage - typically mid-supply via a resistive divider - and outputs connected to their respective inverting inputs. Leaving inputs floating or unconnected risks oscillation and increased supply current.
