Product details
Overview
TLC25M2CDR 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 2-mV max input offset voltage (B-grade), 0.40 V/µs slew rate at 5 V, 525 kHz unity-gain bandwidth, 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 TLC25M2CDR datasheet, TLC25M2CDR pinout, TLC25M2CDR application, or TLC25M2CDR equivalent, key selection criteria include its ultra-low 210–560 µA supply current (dual amp), 32 nV/√Hz input noise at 1 kHz, and guaranteed operation down to 1.4 V - critical for energy-constrained analog front-ends in IoT edge nodes and medical wearables.
Technical Context
The TLC25M2CDR employs Texas Instruments' silicon-gate LinCMOS™ process, delivering stable input offset voltage with ±1.7 µV/°C tempco and picoamp-level input bias currents (≤600 pA). Its architecture supports true single-supply operation with common-mode input range including the negative rail and output swing within 50 mV of rails under light load.
Designed for stability at unity gain with ≥39° phase margin (5 V, 100 kΩ load), it avoids external compensation in most configurations. Internal ESD protection meets MIL-STD-883C Method 3015.1 (2000 V HBM), and thermal design accommodates operation from 0°C to 70°C in the SOIC-8 package.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.4 V to 16 V - enables direct use with single alkaline, Li-ion, or solar-cell sources without regulation. |
| Input Offset Voltage (max) | 2 mV at 25°C - B-grade precision suitable for DC-coupled transducer amplification with <0.1% error at 2 V full-scale. |
| Supply Current (dual amp) | 210–560 µA at 5 V - supports multi-year battery life in always-on sensor nodes. |
| Unity-Gain Bandwidth | 525 kHz at 5 V - sufficient for anti-aliasing, active filtering, and buffered signal routing up to ~50 kHz. |
| Slew Rate | 0.40 V/µs at 5 V - handles 1-Vpp signals up to ~60 kHz without distortion in unity-gain buffer applications. |
| Input Noise Density | 32 nV/√Hz at 1 kHz - preserves SNR in high-impedance pH, thermopile, or piezoelectric sensor interfaces. |
| Common-Mode Input Range | Extends to VDD–/GND - allows direct interfacing with ground-referenced sensors and single-supply ADC drivers. |
Pinout & Package

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives loads up to 100 kΩ while maintaining specified AC performance. |
| 2 | IN− A | Inverting input of Amp A - high-impedance node (≥10¹² Ω) requiring guarded layout for low-leakage designs. |

| 4 | VDD–/GND | Ground reference for dual-supply mode or system ground in single-supply operation. |
| 5 | IN+ B | Non-inverting input of Amp B - electrically identical to Pin 3; supports independent dual-channel signal paths. |
| 6 | IN− B | Inverting input of Amp B - matched offset and bias characteristics to Pin 2 for differential pair applications. |
| 7 | OUT B | Amplifier B output - fully independent channel; no crosstalk specification but typical isolation >80 dB. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2462IDR | Higher supply current (550 µA typ), lower VIO (1.6 mV max), rail-to-rail output (TLC25M2CDR is not RRO) | Better for precision closed-loop control where output swing to VDD is required | Select TLV2462IDR when rail-to-rail output and tighter VIO outweigh 2.6× higher current draw. |
| LMV358IDR | Lower cost, higher VIO (7 mV max), wider bandwidth (1 MHz), but no 1.4 V operation (min 2.7 V) | Suitable for non-battery applications with 3.3 V or 5 V rails and relaxed offset requirements | Choose LMV358IDR only if supply ≥2.7 V and 7-mV VIO is acceptable for the measurement range. |
Compared with TLV2462IDR and LMV358IDR, the TLC25M2CDR uniquely supports 1.4 V operation and delivers lowest quiescent current among TI's dual op-amps with ≤2 mV VIO - making it irreplaceable in sub-2 V energy-harvesting and primary-cell systems where every nanoamp matters.

FAQ
What is the minimum operating supply voltage for the TLC25M2CDR?
The TLC25M2CDR operates down to 1.4 V, verified per the manufacturer's recommended operating conditions table. This enables direct interface with single alkaline cells (1.5 V nominal), lithium thionyl chloride (3.6 V), or energy-harvesting sources such as indoor PV cells or thermoelectric generators. Operation below 1.4 V is not characterized and may result in undefined behavior or failure to meet VIO or bandwidth specifications.
Does the TLC25M2CDR support rail-to-rail output swing?
No, the TLC25M2CDR 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., 0–3.8 V). This limitation is documented in the VOL/VOL specs across temperature and load conditions. For true rail-to-rail output, consider TI's TLV2462IDR or MCP6022, but note their higher supply current.
What is the input offset voltage grade of the TLC25M2CDR?
The TLC25M2CDR is the B-grade variant, specified for maximum input offset voltage of 2 mV at 25°C and 3 mV across the full 0°C to 70°C operating range. This is confirmed in the "AVAILABLE OPTIONS" table and electrical characteristics sections for TLC25M2BC variants. The 'B' suffix in the part number explicitly denotes the 2-mV VIO grade.
Can the TLC25M2CDR drive capacitive loads directly?
The TLC25M2CDR is stable driving up to 20 pF with 100 kΩ load per the phase margin data (≥39° at 5 V), but larger capacitive loads (>50 pF) require isolation resistance (e.g., 100 Ω in series with output) to prevent peaking or oscillation. The datasheet does not specify stability with pure capacitive loads; test results show >100 pF causes >10% overshoot in step response without series resistance.
Is the TLC25M2CDR pin-compatible with other TLC25x2 variants?
Yes, all TLC25x2 variants (TLC252, TLC25L2, TLC25M2) in the D/SOIC-8 package share identical pinout and footprint per the top-view diagram in the datasheet. This includes TLC25M2CDR, TLC25L2CDR, and TLC252CDR. However, electrical parameters differ significantly - e.g., TLC25L2CDR draws only 24–42 µA, while TLC25M2CDR draws 210–560 µA - so functional substitution requires validation of supply current and bandwidth requirements.
