Product details
Overview
TLC25M2CD from Texas Instruments is a LinCMOS™ dual operational amplifier optimized for low-power, single-supply operation across 1.4 V to 16 V. It delivers 560 µA max supply current (at 5 V, 70°C), 2-mV max input offset voltage (B-grade), and rail-to-rail common-mode input range extending to the negative rail - enabling precision signal conditioning in battery-powered sensor interfaces and portable instrumentation.
For engineers reviewing the TLC25M2CD datasheet, TLC25M2CD pinout, TLC25M2CD application, or TLC25M2CD equivalent, key selection criteria include its 0.43 V/µs slew rate at 5 V, 525 kHz unity-gain bandwidth, 32 nV/√Hz input noise at 1 kHz, and compatibility with high-impedance transducer sources requiring sub-µA bias currents.
Technical Context
The TLC25M2CD implements a silicon-gate LinCMOS™ process delivering ultra-low input bias current (≤600 pA) and stable offset voltage grading (2 mV max for B-suffix). Its architecture supports true single-supply operation with common-mode input range including the negative rail and output swing within 50 mV of ground.
It features internal ESD protection rated to 2000 V (MIL-STD-883C, Method 3015.1), operates over 0°C to 70°C, and is characterized for stability at unity gain with capacitive loads up to 20 pF - making it suitable for active filtering and low-noise buffering without external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.4 V to 16 V - enables direct operation from single alkaline, lithium, or solar cells without regulation. |
| Input Offset Voltage (Max) | 2 mV at 25°C - ensures ≤2 mV DC error in precision DC-coupled amplifiers and sensor front-ends. |
| Supply Current (Two Amps) | 560 µA max at 5 V, 70°C - supports multi-year battery life in always-on monitoring systems. |
| Unity-Gain Bandwidth | 525 kHz typical at 5 V - sufficient for anti-aliasing filters, audio preamps, and slow-control loop amplification. |
| Slew Rate | 0.43 V/µs typical at 5 V - limits large-signal settling time to <1 µs for 1-V step inputs. |
| Input Noise Density | 32 nV/√Hz at 1 kHz - preserves SNR in low-level thermocouple or strain gauge signal chains. |
| Common-Mode Input Range | Extends to VDD–/GND - allows direct interfacing with ground-referenced sensors and single-ended sources. |
Pinout & Package
Package: 8-pin SOIC (D package), surface-mount, tape-and-reel compatible (suffix R available).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Inverting amplifier output - drives 100-kΩ load with ≤50 mV low-level saturation. |
| 2 | IN– A | Inverting input - high-impedance node (≥10¹² Ω) for feedback network connection. |
| 3 | IN+ A | Non-inverting input - accepts signals down to GND with no level-shifting circuitry. |
| 4 | VDD–/GND | Power reference - serves as analog ground return for both amplifiers and bias networks. |
| 5 | VDD | Positive supply - accepts 1.4–16 V; decoupling capacitor required near pin for stability. |
| 6 | OUT B | Second amplifier output - independent channel for dual-path signal processing or differential drive. |
| 7 | IN– B | Inverting input for second op-amp - electrically isolated from Channel A per datasheet layout guidelines. |
| 8 | IN+ B | Non-inverting input for second op-amp - supports independent sensor or reference input routing. |
Key Features
| Feature | Design Value |
|---|---|
| LinCMOS™ Process Technology | Enables 600 pA max input bias current - eliminates guard rings and leakage errors in high-Z pH or photodiode circuits. |
| True Single-Supply Operation | Common-mode input includes GND and output swings to within 50 mV of GND - removes need for dual supplies or level shifters. |
| Low-Voltage Capability | Functional at 1.4 V supply - supports direct interface with primary batteries (e.g., AA, AAA) without voltage boosters. |
| ESD Protection | 2000 V HBM rating - reduces field failure risk during PCB handling and assembly without external TVS diodes. |
| Stable Unity-Gain Configuration | No external compensation required - simplifies design of buffers, followers, and integrators with 20-pF capacitive loads. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2462CD | Higher supply current (1.3 mA typ), lower VIO (1.6 mV max), rail-to-rail output (TLC25M2CD is not RRO) | Requires higher power budget; better for precision output swing but less suited for ultra-low-power designs | Select TLV2462CD when output swing to VDD is required and supply current >500 µA is acceptable. |
| LMV358IDR | Lower cost, wider temp range (–40°C to 125°C), higher VIO (7 mV max), 360-µA supply current | Less precise offset performance; better for industrial ambient conditions where extended temperature is critical | Select LMV358IDR for cost-sensitive, non-precision applications operating beyond 70°C. |
Compared with TLV2462CD and LMV358IDR, the TLC25M2CD uniquely balances ultra-low quiescent current (560 µA max), 2-mV VIO grade, and 1.4-V minimum supply - making it the optimal choice for long-life, battery-operated instrumentation where precision and energy efficiency are co-prioritized.

FAQ
What is the maximum supply voltage rating for the TLC25M2CD?
The TLC25M2CD has an absolute maximum supply voltage of 18 V, but its recommended operating range is 1.4 V to 16 V. Exceeding 16 V may cause parametric degradation or reliability issues despite surviving short-term stress. Always observe derating curves in the dissipation rating table for thermal management at elevated voltages and temperatures.
Does the TLC25M2CD support rail-to-rail output swing?
No, the TLC25M2CD does not provide rail-to-rail output. Its output typically swings within 50 mV of GND and within ~1.2 V of VDD at 5 V supply (e.g., VOH ≈ 3.9 V, VOL ≈ 0 mV). For full rail-to-rail output capability, consider alternatives like the TLV2462CD - though at higher quiescent current.
How does the input offset voltage of the TLC25M2CD compare to the TLC25L2CD variant?
The TLC25M2CD (B-suffix) is specified for ≤2 mV max input offset voltage at 25°C, whereas the TLC25L2CD (B-suffix) offers ≤2 mV max but with significantly lower supply current (28 µA vs. 560 µA). The TLC25M2CD trades higher power for improved bandwidth and slew rate - 525 kHz vs. 85 kHz unity-gain bandwidth - making it suitable for faster signal paths.
Can the TLC25M2CD be used with capacitive loads greater than 20 pF?
The TLC25M2CD is characterized for stability with up to 20 pF capacitive load at unity gain. Driving larger capacitive loads (e.g., >50 pF) risks phase margin reduction and potential oscillation. If required, add a series isolation resistor (e.g., 10–100 Ω) between the output and load capacitance to restore stability without compromising DC accuracy.
Is the TLC25M2CD pin-compatible with other devices in the TLC25x2 family?
Yes, the TLC25M2CD shares identical 8-pin SOIC (D) package pinout and footprint with all members of the TLC25x2 family, including TLC252CD, TLC25L2CD, and their A/B-suffix variants. This allows drop-in replacement for offset, speed, or power trade-offs - provided system-level validation confirms stability and noise performance meet requirements.
