Product details
Overview
TLC25M2ACP from Texas Instruments is a LinCMOS™ dual operational amplifier optimized for low-power, single-supply operation with rail-to-rail common-mode input (down to negative rail), 5-mV max input offset voltage (A-grade), and 210–560 µA supply current at 5 V. It delivers 0.40 V/µs slew rate, 525 kHz unity-gain bandwidth, and 32 nV/√Hz input noise-enabling precision signal conditioning in battery-powered sensor interfaces and portable instrumentation.
For engineers reviewing the TLC25M2ACP datasheet, TLC25M2ACP pinout, TLC25M2ACP application, or TLC25M2ACP equivalent, this device is selected for ultra-low quiescent current, true single-supply capability (1.4–16 V), high input impedance (>10¹² Ω), and stable unity-gain performance in energy-constrained analog front-ends.
Technical Context
The TLC25M2ACP uses Texas Instruments' silicon-gate LinCMOS™ process to achieve extremely low input bias current (≤60 pA typ) and input offset current (≤60 pA typ), enabling accurate amplification of high-impedance sources such as piezoelectric sensors and pH electrodes. Its input common-mode range extends to the negative rail, supporting ground-referenced signal acquisition without level-shifting circuitry.
It features internal ESD protection rated to 2000 V (MIL-STD-883C, Method 3015.1), operates across 0°C to 70°C, and is characterized for stable unity-gain operation with 40° phase margin at 5 V and 25°C-making it suitable for active filters, transducer buffers, and low-noise DC-coupled gain stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.4 V to 16 V - enables direct operation from single alkaline, lithium coin cell, or solar-cell sources without regulation. |
| Input Offset Voltage (Max) | 5 mV at 25°C - A-suffix grade ensures tighter DC accuracy than standard C-grade (10 mV), critical for low-gain sensor amplifiers. |
| Supply Current (Two Amps) | 210–560 µA at 5 V, 25°C - supports multi-year battery life in always-on IoT sensor nodes and wearable health monitors. |
| Unity-Gain Bandwidth | 525 kHz (typ) at 5 V - sufficient for anti-aliasing filters, ECG front-ends, and slow-control loop compensation. |
| Slew Rate | 0.40 V/µs (typ) at 5 V - balances speed and power for sub-MHz signal paths while minimizing dynamic power consumption. |
| Input Noise Voltage | 32 nV/√Hz at 1 kHz - lower than TLC25L2 series (68 nV/√Hz), making TLC25M2ACP preferred for medium-bandwidth precision sensing. |
| Common-Mode Input Range | Includes negative rail (e.g., –0.2 V to 3.5 V at 5 V) - eliminates need for input biasing resistors in single-supply configurations. |
Pinout & Package
Package: 8-pin Plastic DIP (P), through-hole, 0.3-inch wide body. RoHS-compliant lead finish, rated for 260°C soldering (10 s).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Output of Amplifier 1 (1OUT) | Low-impedance buffered output capable of driving ≥100 kΩ loads with <50 mV saturation near rails. |
| 2 | Inverting Input of Amplifier 1 (1IN–) | Differential input node with >10¹² Ω impedance; requires matched trace routing to minimize offset drift. |
| 3 | Non-Inverting Input of Amplifier 1 (1IN+) | High-Z input referenced to system ground or bias network; accepts signals down to VDD–/GND. |
| 4 | Negative Supply / Ground (VDD–/GND) | Return path for both amplifiers and bias network; must be low-impedance to minimize PSRR degradation. |
| 5 | Positive Supply (VDD) | Single-supply rail (1.4–16 V); decoupling capacitor (0.1 µF ceramic) required within 1 cm of this pin. |
| 6 | Output of Amplifier 2 (2OUT) | Independent output stage; electrically isolated from 1OUT but shares same supply and ground. |
| 7 | Inverting Input of Amplifier 2 (2IN–) | Second differential input; layout symmetry with Pin 2 recommended for matched thermal drift. |
| 8 | Non-Inverting Input of Amplifier 2 (2IN+) | Second high-Z input; usable for differential pair, instrumentation amp reference, or independent channel. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input common-mode range | Extends to VDD–/GND, enabling ground-sensed signals without external level shifters or dual supplies. |
| Ultra-low input bias current | ≤60 pA typical - preserves signal integrity from high-impedance sources (e.g., glass pH electrodes, photodiodes). |
| Low quiescent current | 210–560 µA total for two op-amps - reduces thermal load and extends battery runtime in portable devices. |
| Stable unity-gain operation | 40° phase margin at 5 V - allows direct use in voltage followers and active filters without external compensation. |
| ESD protection | 2000 V HBM - enhances robustness during PCB handling and field deployment in industrial environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLC25M2CP | Same die, C-grade (10-mV VIO max), higher supply current (300–375 µA at 5 V). | Acceptable where DC accuracy is less critical and cost sensitivity is higher. | Select TLC25M2CP only if 10-mV offset is acceptable and BOM cost reduction is prioritized over precision. |
| TLC25L2ACP | Lower supply current (24–42 µA), lower bandwidth (85 kHz), higher noise (68 nV/√Hz). | Better suited for ultra-low-power, sub-10-kHz applications like smoke detector CO sensing. | Choose TLC25L2ACP when microamp-level quiescent current is mandatory and signal bandwidth is <100 kHz. |
Compared with TLC25M2CP, the TLC25M2ACP provides tighter DC accuracy and lower noise at modest current cost; versus TLC25L2ACP, it trades 20× higher supply current for 2.3× higher bandwidth and half the input noise-ideal for medium-speed precision sensing.

FAQ
What is the maximum supply voltage rating for the TLC25M2ACP?
The TLC25M2ACP has an absolute maximum supply voltage (VDD) rating of 18 V. However, its recommended operating range is 1.4 V to 16 V. Exceeding 16 V may cause parametric degradation or reliability issues, even if below the 18-V absolute limit. Always observe derating curves in the dissipation rating table for the P-package at elevated ambient temperatures.
Does the TLC25M2ACP support true single-supply operation with input signals at ground potential?
Yes, the TLC25M2ACP supports true single-supply operation with input common-mode voltage extending to the negative rail (VDD–/GND). At 5 V supply, the specified common-mode input range is –0.2 V to 3.5 V, allowing ground-referenced signals without external level shifting-critical for interfacing with sensors tied to system ground.
How does the A-suffix in TLC25M2ACP affect input offset voltage specification?
The A-suffix denotes the 5-mV maximum input offset voltage grade at 25°C, tested and binned during production. This is tighter than the standard C-grade (10-mV max) and B-grade (2-mV max). The TLC25M2ACP maintains this 5-mV limit across the full 0°C to 70°C operating range, with a typical average temperature coefficient of 1.7 µV/°C.
Can the TLC25M2ACP drive capacitive loads directly without stability issues?
The TLC25M2ACP is characterized for stable unity-gain operation with ≥100 kΩ resistive loads and ≤20 pF capacitive loads (phase margin ≥40° at 5 V). Driving larger capacitive loads (e.g., >50 pF) requires isolation resistance (≥100 Ω) in series with the output or external compensation per Figure 3 in the datasheet to prevent peaking or oscillation.
Is the TLC25M2ACP pin-compatible with other variants in the TLC25x2 family?
Yes, all TLC25x2 variants-including TLC25M2ACP, TLC25M2CP, TLC25L2ACP, and TLC252ACP-share identical 8-pin DIP (P) and SOIC (D) footprints and pinouts. This allows drop-in substitution between grades (A/B/C) and subfamilies (M/L/2) without PCB redesign, provided supply, bandwidth, and accuracy requirements are verified.
