Product details
Overview
TLC2274MDG4 from Texas Instruments is a quad 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, ±5-V supply operation, and rail-to-rail output swing - enabling direct interfacing with 12-bit ADCs in battery-powered sensor front-ends.
For engineers reviewing the TLC2274MDG4 datasheet, TLC2274MDG4 pinout, TLC2274MDG4 application, or TLC2274MDG4 equivalent, key selection criteria include input bias current (1 pA typ), input offset voltage (≤950 µV max), common-mode input range extending to negative rail, thermal stability across –55°C to 125°C, and SOIC-14 packaging for industrial-grade reliability.
Technical Context
The TLC2274MDG4 uses advanced LinCMOS process technology to achieve rail-to-rail output swing while maintaining low input bias current and high input impedance (>10¹² Ω). Its architecture supports both single-supply (up to 16 V) and dual-supply (±2.2 V to ±8 V) operation, with common-mode input voltage range including the negative rail - critical for ground-referenced transducer interfaces.
It features internal compensation for unity-gain stability, 75–80 dB CMRR and PSRR over temperature, and phase margin of 52° at unity gain with 100-pF capacitive load - ensuring robust performance in closed-loop configurations without external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 2.25 MHz - enables stable closed-loop gain up to 100 at 22.5 kHz for anti-aliasing filter design. |
| Slew rate | 3.6 V/µs - supports 10-kHz full-scale sine output at 2.3-V peak without distortion in ±5-V systems. |
| Input voltage noise | 9 nV/√Hz at 1 kHz - preserves SNR in high-gain amplification of microvolt-level piezoelectric signals. |
| Input bias current | 1 pA typical - minimizes voltage error across >1-MΩ source impedances in pH or thermocouple circuits. |
| Input offset voltage | ≤950 µV maximum - ensures ≤0.02% gain error in 5-V full-scale instrumentation amplifier stages. |
| Supply voltage range | ±2.2 V to ±8 V - allows operation from Li-ion (3.7 V) or dual AA (3 V) supplies with headroom for rail-to-rail output. |
| Operating temperature | –55°C to +125°C - qualified for military and automotive under-hood applications per M-level spec. |
Pinout & Package
TLC2274MDG4 is housed in a 14-pin SOIC (D package) with body size 3.91 mm × 8.65 mm, compliant with JEDEC MS-012, and rated for surface-mount reflow per J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Amplified output of Channel 1; rail-to-rail swing supports direct ADC input without level-shifting. |
| 2 | IN1− | Inverting input of Channel 1; matched to IN1+ for <100-µV offset in differential configurations. |
| 3 | IN1+ | Non-inverting input of Channel 1; accepts common-mode voltages down to VDD− (negative rail). |
| 4 | VDD+ | Positive supply terminal; decoupling capacitor required within 1 cm for stability at >1 MHz. |
| 5 | IN2+ | Non-inverting input of Channel 2; electrically isolated from Channel 1 for multi-sensor signal chains. |
| 6 | IN2− | Inverting input of Channel 2; supports unity-gain inverter or transimpedance configurations. |
| 7 | OUT2 | Amplified output of Channel 2; independent output stage prevents crosstalk below –80 dB at 10 kHz. |
| 8 | NC | No connection; no internal bond wire - must remain unconnected per TI design guidelines. |
| 9 | IN3+ | Non-inverting input of Channel 3; enables 3-channel simultaneous sampling in compact analog front-ends. |
| 10 | IN3− | Inverting input of Channel 3; referenced to same VDD− as all channels for consistent common-mode rejection. |
| 11 | VDD− | Negative supply terminal; serves as reference for all inputs and outputs in split-supply mode. |
| 12 | IN4+ | Non-inverting input of Channel 4; supports fourth independent sensor channel without additional ICs. |
| 13 | IN4− | Inverting input of Channel 4; layout symmetry recommended to match IN1−/IN2−/IN3− parasitics. |
| 14 | OUT4 | Amplified output of Channel 4; fully specified for drive capability up to ±5 mA into resistive loads. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLC2274CDR | Commercial-grade (0°C to 70°C); identical electrical specs except wider VIO max (2500 µV) and no M-level qualification. | Limited to indoor consumer electronics; not suitable for extended temperature or mission-critical environments. | Select when cost sensitivity outweighs environmental ruggedness and long-term offset stability requirements. |
| TLV2434IDR | Lower supply current (1.2 mA/ch vs. 1.5 mA/ch), higher GBW (2.7 MHz), but higher input noise (17 nV/√Hz) and narrower VIO spec (2000 µV max). | Better for high-speed, low-power portable devices where noise floor is less critical than battery runtime. | Choose when optimizing for sub-1-µA sleep current and faster settling in data-acquisition systems with relaxed noise budgets. |
Compared with TLC2274CDR, the TLC2274MDG4 provides guaranteed performance over –55°C to +125°C and tighter input offset voltage (≤950 µV), making it suitable for harsh environments; versus TLV2434IDR, it trades 8 nV/√Hz lower noise and superior DC precision for slightly higher quiescent current and lower bandwidth - favoring measurement fidelity over speed.

FAQ
What is the maximum supply voltage for TLC2274MDG4?
The TLC2274MDG4 supports a maximum dual-supply voltage of ±8 V (16 V total) and a maximum single-supply voltage of 16 V. Absolute maximum ratings specify VDD+ ≤ +8 V and VDD− ≥ –8 V; operation beyond these limits risks permanent damage. Recommended operating range is ±2.2 V to ±8 V for split supplies or +4.4 V to +16 V for single supplies.
Does TLC2274MDG4 support rail-to-rail input?
No, the TLC2274MDG4 does not support rail-to-rail input. 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) under recommended conditions. This allows ground-referenced inputs in single-supply systems but requires input signal headroom at the high end - unlike true rail-to-rail input op-amps such as the TLV2464.
What is the input offset voltage specification for TLC2274MDG4?
The TLC2274MDG4 has a maximum input offset voltage of 950 µV at TA = 25°C, with full-range (–55°C to +125°C) maximum of 1500 µV. This applies to the 'A' variant (TLC2274A), which the 'M' grade implements. The standard TLC2274 variant has a higher max of 2500 µV - confirming that TLC2274MDG4 is the precision-grade version for high-accuracy DC-coupled applications.
Can TLC2274MDG4 drive capacitive loads directly?
Yes, the TLC2274MDG4 is unity-gain stable and characterized for driving up to 100 pF capacitive loads without oscillation, as verified by phase margin (52°) and gain margin (10 dB) measurements in the datasheet. For loads exceeding 100 pF, an isolation resistor (10–100 Ω) between output and capacitance is recommended to maintain stability in high-frequency closed-loop configurations.
Is TLC2274MDG4 pin-compatible with other TLC2274 variants?
Yes, all TLC2274 variants - including TLC2274CDR, TLC2274IDR, TLC2274AMDR, and TLC2274MDG4 - share identical SOIC-14 pinouts and electrical pin functions per TI's Pin Functions table. Differences lie solely in temperature grading, input offset voltage limits, and qualification testing - not in physical layout or signal mapping - enabling drop-in replacement across grades when environmental and precision requirements align.
