Product details
Overview
TLC27M2CPS from Texas Instruments is a dual precision CMOS operational amplifier with 10 mV max input offset voltage at 25°C, rail-to-rail output swing down to negative rail, and operation from 3 V to 16 V supply across 0°C to 70°C. It delivers 0.43 V/µs slew rate, 32 nV/√Hz input noise at 1 kHz, and 525 kHz unity-gain bandwidth at VDD = 5 V - enabling low-power sensor signal conditioning in battery-powered instrumentation.
For engineers reviewing the TLC27M2CPS datasheet, TLC27M2CPS pinout, TLC27M2CPS application, or TLC27M2CPS equivalent, this page provides verified package mapping (8-pin plastic DIP), confirmed LinCMOS process advantages, real-world common-mode input range (−0.2 V to 3.5 V), and two validated alternative op-amps for design flexibility in analog front-end upgrades.
Technical Context
The TLC27M2CPS uses Texas Instruments' silicon-gate LinCMOS technology, delivering high input impedance (10¹² Ω typ), ultra-low input bias current (0.6 pA typ at 25°C), and built-in ESD protection rated to 2000 V per MIL-STD-883C Method 3015.2. Its architecture supports single-supply operation with common-mode input voltage extending below ground.
It features internal phase compensation for unity-gain stability, latch-up immunity, and robust output drive capability (±30 mA). The device exhibits stable large-signal differential voltage amplification (15–170 V/mV) and strong rejection of supply and common-mode interference (CMRR ≥ 60 dB, kSVR ≥ 60 dB).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | 10 mV max at 25°C - defines worst-case DC error in precision gain stages without trimming |
| Supply Voltage Range | 3 V to 16 V - enables direct use with single Li-ion, multi-cell alkaline, or industrial 5/12 V rails |
| Common-Mode Input Range | −0.2 V to 3.5 V at VDD = 5 V - supports sensing signals referenced below ground (e.g., shunt current monitors) |
| Slew Rate | 0.43 V/µs typ at 25°C - sufficient for <10 kHz full-scale step response in 12-bit DAQ systems |
| Unity-Gain Bandwidth | 525 kHz typ at VDD = 5 V - suitable for anti-aliasing filters and active RC stages up to ~50 kHz |
| Input Noise Density | 32 nV/√Hz at 1 kHz - low enough for µV-level thermocouple or strain gauge amplification |
| Quiescent Current | 210 µA typ per amplifier at 25°C - enables dual-channel operation under 500 µA total for ultra-low-power nodes |
Pinout & Package
Package: 8-pin plastic DIP (P package), through-hole mounting, 0.3-inch width, RoHS-compliant lead finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Inverting amplifier output - drives loads up to ±30 mA; swings to negative rail |
| 2 | IN− A | Inverting input - high-impedance node (10¹² Ω); accepts signals down to −0.2 V |
| 3 | IN+ A | Non-inverting input - same voltage range and impedance as IN− A |
| 4 | GND | Analog ground reference - shared return for both amplifiers and supply decoupling |
| 5 | IN+ B | Non-inverting input of second amplifier - electrically isolated but on same die |
| 6 | IN− B | Inverting input of second amplifier - independent bias path, matched to Channel A |
| 7 | OUT B | Second amplifier output - identical drive strength and rail-swing capability as OUT A |
| 8 | VCC | Positive supply rail - accepts 3–16 V; no separate VEE required for single-supply use |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing to negative rail | Enables true single-supply operation without level-shifting circuitry in 0–5 V systems |
| 10¹² Ω typical input impedance | Minimizes loading error on high-Z sources like piezoelectric sensors or pH electrodes |
| ESD protection to 2000 V (HBM) | Reduces need for external transient suppression in board-level ESD-prone environments |
| Latch-up immunity | Prevents catastrophic failure during overvoltage transients on inputs or outputs |
| Low 32 nV/√Hz input noise | Supports 16-bit-equivalent resolution in DC-coupled sensor interfaces with ≤100 Hz bandwidth |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual CMOS op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLC27L2CPS | Lower supply current (190 µA typ), lower slew rate (0.17 V/µs), 25 mV max VIO | Targeted at ultra-low-power, low-bandwidth (<10 kHz) applications where offset is less critical | Select when power budget is tighter than DC accuracy requirements |

FAQ
What is the maximum input offset voltage specification for TLC27M2CPS at 25°C?
The maximum input offset voltage for TLC27M2CPS at 25°C is 10 mV, as specified in the Electrical Characteristics table for the C-suffix (0°C to 70°C) grade. This value applies under standard test conditions (VO = 1.4 V, VIC = 0 V, VDD = 5 V) and represents the worst-case DC error introduced by the amplifier in precision gain stages without external trimming.
Does TLC27M2CPS support true single-supply operation with input signals below ground?
Yes, TLC27M2CPS supports true single-supply operation with its common-mode input voltage range extending to −0.2 V at VDD = 5 V. This allows the device to accurately amplify signals referenced slightly below ground - such as those from current-sense shunts or certain transducer bridges - without requiring a negative supply rail or level-shifting circuitry.
What is the recommended operating supply voltage range for TLC27M2CPS?
The recommended operating supply voltage range for TLC27M2CPS is 3 V to 16 V across the 0°C to 70°C temperature range. This wide range enables direct compatibility with common power sources including single Li-ion batteries (3.0–4.2 V), 5 V logic rails, and industrial 12 V systems - all while maintaining specified performance for input offset, CMRR, and output swing.
Can TLC27M2CPS drive a 100 kΩ load while maintaining rail-to-rail output swing?
Yes, TLC27M2CPS is characterized to deliver rail-to-rail output swing into a 100 kΩ load. At VDD = 5 V and 25°C, the low-level output voltage (VOL) is guaranteed ≤50 mV and high-level output voltage (VOH) ≥3.2 V - confirming full swing from near ground to within ~0.8 V of VDD. This behavior is maintained across the full operating temperature range.
Is TLC27M2CPS pin-compatible with other devices in the TLC27x family?
Yes, TLC27M2CPS shares the same 8-pin DIP (P) package pinout with all C-suffix variants in the TLC27x family, including TLC27L2CPS, TLC27M7CPS, and TLC27M2ACPS. This allows drop-in substitution for different offset grades without PCB changes - provided the system's supply voltage, temperature range, and performance requirements align with the selected variant.
