Product details
Overview
TLC2274MDRG4 from Texas Instruments is a quad rail-to-rail output operational amplifier designed for precision 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, 1-pA typical input bias current, and rail-to-rail output swing - enabling high-fidelity interfacing with ADCs in battery-powered sensor front-ends.
For engineers reviewing the TLC2274MDRG4 datasheet, TLC2274MDRG4 pinout, TLC2274MDRG4 application, or TLC2274MDRG4 equivalent, key selection criteria include its ±2.2 V to ±8 V supply range, 950 µV max input offset voltage (A-grade), low-noise performance at low frequencies, rail-to-rail output capability under load, and suitability for transducer interfaces requiring high input impedance and micropower operation.
Technical Context
The TLC2274MDRG4 uses advanced LinCMOS process technology to achieve rail-to-rail output swing while maintaining low input bias current and low noise. Its input stage operates down to the negative rail, supporting true single-supply operation with common-mode input range extending to VDD−.
It features unity-gain stable compensation, 50° phase margin, and 10 dB gain margin with 10-kΩ load and 100-pF capacitive load - ensuring robust stability in precision buffer and active filter configurations without external compensation.
Key Specifications

| Supply Voltage Range | ±2.2 V to ±8 V - supports industrial and automotive dual-rail systems and wide-input single-supply designs (e.g., 4.4 V to 16 V) |
| Gain-Bandwidth Product | 2.25 MHz - enables stable closed-loop operation up to ~200 kHz at AV = 10 for anti-aliasing or sensor amplification |
| Slew Rate | 3.6 V/µs - supports 10-bit+ resolution at >100 kHz full-scale step response without slewing distortion |
| Input Offset Voltage (max) | 950 µV at TA = 25°C - ensures ≤0.02% error in 5-V full-scale instrumentation amplifier stages |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLC2274CDR | Commercial-grade (0°C to 70°C), same SOIC-14 package and electrical specs except wider VIO max (2500 µV) | Lower cost for non-industrial ambient environments; not qualified for extended temperature operation | Select when full industrial temp range is unnecessary and cost sensitivity outweighs offset precision |
| TLV2434IDR | Higher supply current (1.2 mA/ch vs. 1.2 mA/ch), lower noise (11 nV/√Hz), but only 1.7-MHz GBW and no M-grade qualification | Better noise performance but reduced bandwidth; lacks military-grade (-55°C to +125°C) support | Choose for ultra-low-noise, moderate-speed applications where extended temperature range is not required |
Compared with TLC2274CDR and TLV2434IDR, the TLC2274MDRG4 provides guaranteed military-grade temperature operation, tighter input offset voltage (≤950 µV), and proven rail-to-rail output drive into 10-kΩ loads - making it optimal for high-reliability embedded systems where long-term parametric stability matters.

FAQ
What is the maximum operating temperature range for the TLC2274MDRG4?
The TLC2274MDRG4 is an M-grade device rated for operation from –55°C to +125°C. This military-temperature qualification ensures reliable performance in avionics, downhole tools, and other extreme-environment applications where commercial or industrial grade parts would fail. The datasheet specifies all electrical characteristics across this full range, including input offset voltage and supply current.
Does the TLC2274MDRG4 support true single-supply operation with input signals referenced to ground?
Yes, the TLC2274MDRG4 supports true single-supply operation: its common-mode input voltage range includes the negative rail (VDD−), which is GND in single-supply configurations. This allows direct connection of ground-referenced sensors - such as thermistors or bridge circuits - to the non-inverting inputs without level-shifting circuitry, simplifying design and improving DC accuracy.
What is the typical supply current per channel for the TLC2274MDRG4 at ±5 V?
At ±5 V supply and TA = 25°C, the TLC2274MDRG4 draws 4.8 mA total quiescent current, equating to 1.2 mA per channel. This value remains stable across the full operating temperature range (–55°C to +125°C), with a maximum of 6 mA total under worst-case conditions - enabling predictable power budgeting in multi-channel, low-power systems.
Can the TLC2274MDRG4 drive a 10-kΩ load rail-to-rail while maintaining specified AC performance?
Yes, the TLC2274MDRG4 is characterized for rail-to-rail output swing into ≥10-kΩ loads. At ±5 V, it delivers ±4.85 V minimum peak output voltage with 200-µA load current, and maintains 2.25-MHz gain-bandwidth and 3.6-V/µs slew rate under those conditions - confirming full dynamic range and fidelity for driving precision ADCs or active filters without external buffers.
Is the TLC2274MDRG4 pin-compatible with other devices in the TLC227x family?
Yes, the TLC2274MDRG4 shares identical SOIC-14 pinout with all TLC2274 variants (e.g., TLC2274CDR, TLC2274AIDR, TLC2274MFK). Pin functions - including VDD+, VDD−, and all four channel I/O - are consistent across grades and packages, enabling drop-in replacement during qualification or cost optimization without PCB redesign.
