Product details
Overview
TLC25M2ACD 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 5 mV max input offset voltage (VIO), 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 TLC25M2ACD datasheet, TLC25M2ACD pinout, TLC25M2ACD application, or TLC25M2ACD equivalent, this page provides verified electrical specifications, package mapping to SOIC-8 (D), validated alternative options, and design-critical context on input bias current (≤60 pA), noise (32 nV/√Hz), and stability at unity gain - all confirmed per SLOS002I Rev. March 2001.
Technical Context
The TLC25M2ACD uses Texas Instruments' silicon-gate LinCMOS™ process to achieve ultra-low input bias and offset currents while maintaining stable DC performance across temperature. Its input stage supports true single-supply operation with common-mode voltage down to VDD–/GND, and internal ESD protection withstands 2000 V per MIL-STD-883C Method 3015.1.
This variant belongs to the TLC25M2 family - the medium-bias tier - balancing speed (525 kHz B1), power (560 µA max IDD at 70°C), and precision (5 mV VIO max) between the high-speed TLC252 and ultra-low-power TLC25L2 families. It is characterized for 0°C to 70°C operation and specified with RL = 100 kΩ loads.
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 cells without regulation. |
| Input Offset Voltage (VIO) | 5 mV max at 25°C - ensures ≤5 mV DC error in precision DC-coupled amplifiers and transducer front-ends. |
| Slew Rate | 0.40 V/µs at 5 V, RL = 100 kΩ - supports audio-frequency signal buffering and moderate-speed active filtering. |
| Unity-Gain Bandwidth (B1) | 525 kHz typical at 5 V - sufficient for anti-aliasing filters, sensor amplification, and low-bandwidth control loops. |
| Input Bias Current | 60 pA max at 70°C - preserves accuracy in high-impedance pH, photodiode, or piezoelectric sensor circuits. |
| Input Noise Voltage | 32 nV/√Hz at 1 kHz - suitable for low-level analog signal conditioning where thermal noise dominates. |
| Common-Mode Input Range | Extends to VDD–/GND - allows ground-referenced inputs in single-supply systems without level-shifting. |
Pinout & Package
Package: SOIC-8 (D), 3.9 mm × 4.9 mm body, 1.27 mm pitch, tape-and-reel compatible (suffix R available).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Inverting amplifier output - drives 100 kΩ load with 0.4 V/µs slew rate and rail-swing capability. |
| 2 | IN− A | Inverting input - high-impedance node (≥10¹² Ω) for feedback networks and differential sensing. |
| 3 | IN+ A | Non-inverting input - accepts signals down to VDD–/GND; critical for single-supply sensor biasing. |
| 4 | VDD–/GND | Ground reference - shared return for both amplifiers; must be low-impedance for noise immunity. |
| 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-stage gain, differential output, or dual-sensor interface. |
| 7 | IN− B | Inverting input for second op-amp - electrically isolated from Channel A; supports dual independent circuits. |
| 8 | IN+ B | Non-inverting input for second op-amp - identical DC and AC specs as Pin 3; enables matched dual configurations. |
Key Features
| Feature | Design Value |
|---|---|
| True single-supply operation | Common-mode input includes VDD–/GND - eliminates need for dual supplies or level-shifters in portable designs. |
| Ultra-low input bias current | ≤60 pA max at 70°C - maintains gain accuracy in MΩ-range feedback networks used with piezoresistive sensors. |
| Low-voltage compatibility | Operates down to 1.4 V - supports direct integration with energy-harvesting sources and coin-cell-powered devices. |
| ESD-protected inputs | Rated to 2000 V HBM - reduces risk of field failure during PCB handling and system integration. |
| Stable at unity gain | Phase margin ≥40° at B1 - ensures reliable operation in voltage-follower, buffer, and active filter configurations. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLC25M2CD | 10 mV max VIO (vs. 5 mV for TLC25M2ACD); otherwise identical pinout, bias, and speed. | Acceptable where higher DC error budget exists (e.g., non-precision gain stages). | Select TLC25M2CD only if 10 mV VIO meets system offset requirements and cost savings justify reduced precision. |
| MCP6022-I/SN | Higher supply current (120 µA/ch vs. 280 µA total), lower VIO (250 µV), rail-to-rail output, but requires ≥2.7 V supply. | Not viable for sub-2.7 V systems (e.g., single alkaline or NiMH); superior for precision above 2.7 V. | Choose MCP6022-I/SN only when operating ≥2.7 V and sub-mV offset is mandatory; not drop-in for 1.4–2.7 V use cases. |
Compared with TLC25M2CD, the TLC25M2ACD provides tighter DC accuracy at no layout or supply change; versus MCP6022-I/SN, it enables lower-voltage operation but trades off output swing and offset precision - making TLC25M2ACD optimal for cost-sensitive, wide-supply, battery-constrained analog front-ends.

FAQ
What is the maximum supply voltage rating for the TLC25M2ACD?
The TLC25M2ACD has an absolute maximum supply voltage (VDD) rating of 18 V, as specified in the SLOS002I datasheet Absolute Maximum Ratings table. However, its recommended operating range is 1.4 V to 16 V. Exceeding 16 V may compromise long-term reliability or parametric performance, even if below the 18 V stress limit.
Does the TLC25M2ACD support rail-to-rail output swing?
No, the TLC25M2ACD does not provide rail-to-rail output swing. Its output voltage swing is limited - for example, at 5 V supply and RL = 100 kΩ, VOH is typically 3.9 V and VOL is ≤50 mV. The device features rail-to-rail *input* common-mode range (including VDD–/GND), but output swing remains within ~1 V of each rail under load.
What is the input bias current specification for TLC25M2ACD at 70°C?
The TLC25M2ACD specifies a maximum input bias current (IIB) of 600 pA at 70°C, per the "electrical characteristics at specified free-air temperature, VDD = 5 V" table in SLOS002I. At 25°C, the typical value is 0.6 pA, with a maximum of 60 pA - confirming its suitability for high-impedance sensor interfacing across the full commercial temperature range.
Is the TLC25M2ACD pin-compatible with other variants in the TLC25x2 family?
Yes, the TLC25M2ACD is pin-compatible with all D-package variants in the TLC25x2 family (e.g., TLC252CD, TLC25L2ACD, TLC25M2BCD), sharing identical SOIC-8 pinout, terminal functions, and footprint. This allows direct substitution within the same package grade when VIO, bias, or speed requirements align - though system-level validation of offset, bandwidth, and supply current is required.
What is the unity-gain bandwidth of TLC25M2ACD at 10 V supply?
At VDD = 10 V and TA = 25°C, the TLC25M2ACD has a typical unity-gain bandwidth (B1) of 635 kHz, as documented in the "operating characteristics, VDD = 10 V" table of SLOS002I. This increases from 525 kHz at 5 V, reflecting improved small-signal performance with higher supply voltage - useful for optimizing bandwidth in higher-voltage portable systems.
