Product details
Overview
TLC2274MPWREP from Texas Instruments is a quad rail-to-rail output operational amplifier optimized for precision, low-noise signal conditioning in extended-temperature industrial and aerospace applications. It delivers 2.2 MHz gain-bandwidth product, 3.6 V/µs slew rate, 9 nV/√Hz input voltage noise at 1 kHz, 1 pA typical input bias current, and 950 µV maximum input offset voltage at 25°C - enabling high-fidelity interfacing with piezoelectric sensors and ADCs.
For engineers reviewing the TLC2274MPWREP datasheet, TLC2274MPWREP pinout, TLC2274MPWREP application, or TLC2274MPWREP equivalent, this page provides verified electrical specifications, TSSOP-14 package layout, rail-to-rail output behavior across ±2.2 V to ±8 V supplies, and validated alternatives for design-in continuity in harsh-environment analog front-ends.
Technical Context
The TLC2274MPWREP uses Advanced LinCMOS™ process technology to achieve rail-to-rail output swing while maintaining low input bias current and low noise - a combination uncommon in CMOS op-amps of its era. Its input stage operates with common-mode voltage range extending to the negative rail, supporting single-supply sensor interfaces down to GND.
It is fully characterized over −55°C to +125°C, qualified per JEDEC standards including HAST, temperature cycling, and electromigration testing. The device exhibits stable unity-gain operation with ≥50° phase margin into 10 kΩ//100 pF loads and supports both single-supply (up to 16 V) and split-supply (±8 V) configurations.
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) - enables direct use with 5 V, ±5 V, and 12 V systems without level-shifting. |
| Gain-Bandwidth Product | 2.2 MHz typ - supports closed-loop bandwidths up to ~200 kHz in unity-gain buffer or 10× gain configurations. |
| Slew Rate | 3.6 V/µs typ - ensures <1.5 µs settling to 0.1% for 2 V step, suitable for medium-speed data acquisition. |
| Input Offset Voltage | 950 µV max at 25°C - enables DC-coupled amplification of mV-level signals without significant baseline error. |
| Input Bias Current | 1 pA typ - preserves signal integrity when driving from high-impedance sources like pH electrodes or piezoelectric transducers. |
| Output Swing | Rail-to-rail (within 10–150 mV of rails depending on load) - maximizes dynamic range when driving SAR or sigma-delta ADCs directly. |
| Input Voltage Noise | 9 nV/√Hz at 1 kHz - two times lower than legacy TLC274, critical for low-amplitude sensor signal fidelity. |
Pinout & Package
TLC2274MPWREP is housed in a 14-pin TSSOP (PW) package with 0.65 mm pitch, rated for −55°C to +125°C operation and qualified for space-level reliability under enhanced DMS and qualification pedigree protocols.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Amplifier A output - drives external load or next-stage input; rail-to-rail capable. |
| 2 | 1IN− | Inverting input of Amp A - high-impedance node (10¹² Ω), sensitive to PCB leakage. |
| 3 | 1IN+ | Non-inverting input of Amp A - same impedance as IN−; accepts common-mode voltages to VDD−. |
| 4 | VDD+ | Positive supply rail - must be decoupled locally with 0.1 µF ceramic capacitor. |
| 5 | 2IN+ | Non-inverting input of Amp B - electrically identical to Pin 3; supports independent channel routing. |
| 6 | 2IN− | Inverting input of Amp B - matches Pin 2 performance; layout symmetry recommended. |
| 7 | 2OUT | Amplifier B output - shares same AC/DC specs as Pin 1; usable for differential drive or dual-channel buffering. |
| 8 | 4OUT | Amplifier D output - fourth independent output; enables 4-channel signal conditioning in one footprint. |
| 9 | 4IN− | Inverting input of Amp D - identical input structure to Pins 2 and 6; supports multi-sensor inputs. |
| 10 | 4IN+ | Non-inverting input of Amp D - completes quad-channel input set; all four amps are fully independent. |
| 11 | VDD− | Negative supply rail (or GND in single-supply) - return path for all four amplifiers' quiescent current. |
| 12 | 3IN+ | Non-inverting input of Amp C - third channel input; allows simultaneous processing of three or four analog channels. |
| 13 | 3IN− | Inverting input of Amp C - matches other IN− pins; supports inverting gain stages per channel. |
| 14 | 3OUT | Amplifier C output - final independent output; completes full quad-opamp functionality in TSSOP-14. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Delivers full dynamic range into 10 kΩ loads - eliminates need for level-shifting before 12-bit+ ADCs. |

| Extended temperature range (−55°C to +125°C) | Qualified for aerospace, downhole, and military platforms where commercial-grade parts fail. |
| Low 1/f and broadband noise (9 nV/√Hz) | Enables accurate amplification of microvolt-level signals from strain gauges or electrophysiology sensors. |
| Enhanced Diminishing Manufacturing Sources (DMS) support | Guarantees long-term component availability and controlled obsolescence management for legacy systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad rail-to-rail output op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2474IPW | Lower supply current (1.3 mA/amp), but only rated to 125°C (not −55°C); no enhanced DMS or pedigree qualification. | Not suitable for space, downhole, or military deployments requiring −55°C startup or long-term supply continuity. | Select TLV2474IPW only for commercial/industrial designs where extended temperature and DMS are not required. |
| OPA4340UA | Higher precision (125 µV VIO max), but limited to 105°C max ambient and no −55°C rating; higher cost and shorter supply horizon. | Appropriate for lab instrumentation or medical devices needing tighter DC specs, but not for ruggedized embedded systems. | Choose OPA4340UA when sub-200 µV offset is mandatory and environmental grade is secondary. |
Compared with TLV2474IPW and OPA4340UA, the TLC2274MPWREP uniquely combines −55°C to +125°C operation, rail-to-rail output, 1 pA input bias, and DMS pedigree - making it the only option qualified for long-life, high-reliability analog signal chains in aerospace and defense.

FAQ
What is the maximum operating temperature range for the TLC2274MPWREP?
The TLC2274MPWREP is fully specified and qualified for continuous operation from −55°C to +125°C. This extended range is validated per JEDEC standards including HAST, temperature cycling, and electromigration testing - confirming suitability for downhole, avionics, and military vehicle applications where commercial-grade op-amps fail.
Does the TLC2274MPWREP support true rail-to-rail input common-mode range?
No - the TLC2274MPWREP features rail-to-rail *output* swing, but its common-mode input voltage range extends only to the negative rail (VDD−) and up to VDD+ − 1.5 V. For example, with ±5 V supplies, VICR spans −5 V to +3.5 V. This supports single-supply operation with ground-referenced sensors but does not allow input signals to reach the positive rail.
What is the typical supply current consumption of the TLC2274MPWREP?
The TLC2274MPWREP draws 4.4 mA typical total supply current (1.1 mA per amplifier) at 5 V with no load. At ±5 V, IDD is 4.8 mA typical. This value remains stable across the full −55°C to +125°C range, making it predictable for battery-life calculations in remote monitoring systems.
Can the TLC2274MPWREP drive capacitive loads directly?
Yes - the TLC2274MPWREP is stable with up to 100 pF capacitive load in unity-gain configuration, exhibiting ≥50° phase margin. For loads >100 pF, external isolation resistance (e.g., 10–50 Ω in series with the output) is recommended to maintain stability, especially in high-impedance sensor buffering applications.
Is the TLC2274MPWREP pin-compatible with the standard TLC2274 family?
Yes - the TLC2274MPWREP uses the same TSSOP-14 pinout as the commercial TLC2274 and TLC2274A variants. All four amplifier sections, supply pins, and input/output assignments match identically, enabling drop-in replacement in existing designs that require extended temperature and enhanced reliability qualifications.
