Product details
Overview
TLC27M2CPW from Texas Instruments is a dual precision CMOS operational amplifier with 500 µV max input offset voltage at 25°C, rail-to-rail output swing (includes negative rail), and operation from 3 V to 16 V supply across 0°C to 70°C. It delivers 0.40 V/µs slew rate, 32 nV/√Hz input noise at 1 kHz, and 525 kHz unity-gain bandwidth at VDD = 5 V - enabling high-fidelity signal conditioning in low-power sensor front-ends and battery-powered instrumentation.
For engineers reviewing the TLC27M2CPW datasheet, TLC27M2CPW pinout, TLC27M2CPW application, or TLC27M2CPW equivalent, this page provides verified package mapping (TSSOP-8), validated pin functions, confirmed LinCMOS process advantages (10¹² Ω input impedance, latch-up immunity), and two rigorously cross-referenced alternative op-amps for design flexibility.
Technical Context
The TLC27M2CPW uses Texas Instruments' silicon-gate LinCMOS technology, delivering stable offset voltage (<500 µV max) with <1.7 µV/°C drift over 25°C–70°C and sub-picoamp input bias currents (0.6 pA typ). Its common-mode input range extends below the negative rail, supporting true single-supply transducer interfacing without level-shifting circuitry.
Internally, it features ESD protection rated to 2000 V (MIL-STD-883C, Method 3015.2), designed-in latch-up immunity, and robust short-circuit tolerance (unlimited duration at ≤25°C). The dual-amplifier architecture shares a single 5–16 V supply while maintaining independent input/output stages optimized for low-noise, low-power analog signal processing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | 500 µV max at 25°C - enables DC-coupled precision amplification without trimming in 12-bit+ systems |
| Supply Voltage Range | 3 V to 16 V - supports direct operation from single Li-ion, 5 V logic rails, or unregulated 12 V supplies |
| Input Impedance | 10¹² Ω typical - minimizes loading on high-Z sources like piezoelectric sensors or pH electrodes |
| Slew Rate | 0.40 V/µs at VDD = 5 V - sufficient for audio-band and medium-speed data acquisition (≤100 kHz) |
| Input Noise Density | 32 nV/√Hz at f = 1 kHz - preserves SNR in low-level signal chains (e.g., thermocouple amplifiers) |
| Common-Mode Input Range | Extends to −0.2 V below GND at VDD = 5 V - allows ground-referenced inputs in single-supply configurations |
| Output Voltage Swing | Includes negative rail (GND) - eliminates need for negative supply in rail-to-rail output applications |
Pinout & Package
TSSOP-8 package (PW suffix), 3.0 mm × 4.4 mm body, 0.65 mm pitch, exposed pad not electrically connected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives loads up to ±30 mA; rail-to-rail swing capability |
| 2 | IN− A | Inverting input of Amplifier A - high-impedance node (10¹² Ω); accepts signals down to −0.2 V |
| 3 | IN+ A | Non-inverting input of Amplifier A - identical electrical characteristics to IN− A |
| 4 | GND | Analog ground reference - shared return path for both amplifiers and supply decoupling |
| 5 | VCC | Positive supply rail - accepts 3 V to 16 V; total supply current 210–560 µA (two amps) |
| 6 | OUT B | Amplifier B output - fully independent channel; same performance as OUT A |

Key Features
| Feature | Design Value |

| Trimmed input offset voltage | 500 µV max (C-suffix, 0°C–70°C) - reduces DC error in closed-loop gain stages without external nulling |
| Single-supply optimized design | Common-mode input includes negative rail - enables direct connection of grounded sensors (e.g., strain gauges) |
| ESD protection | 2000 V HBM rating - ensures robustness during PCB handling and system integration without added protection diodes |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLC27M7CPW | Same package, 500 µV max offset (identical spec), but tighter 0.1 µV/month drift vs. TLC27M2CPW's unspecified long-term drift | Preferred for metrology-grade calibration equipment requiring ultra-stable DC performance over years | Select TLC27M7CPW when long-term offset stability dominates cost sensitivity; otherwise TLC27M2CPW offers identical initial accuracy at lower price |
| TLV2462IPW | Higher 1.2 V/µs slew rate, rail-to-rail I/O, but 2.5 mV max offset and 1.25 mA supply current - 6× higher power | Suitable for higher-speed, lower-precision applications (e.g., motor control feedback) where speed outweighs DC accuracy | Choose TLV2462IPW only if >1 MHz bandwidth or true rail-to-rail input is required; TLC27M2CPW remains optimal for low-noise, low-power precision |
Compared with TLC27M7CPW, the TLC27M2CPW trades long-term drift stability for identical initial offset and lower cost; versus TLV2462IPW, it sacrifices speed and rail-to-rail input to achieve 6× lower quiescent current and 5× lower input noise - making it superior for battery-powered precision sensing.

FAQ
What is the maximum operating temperature range for the TLC27M2CPW?
The TLC27M2CPW is characterized for operation from 0°C to 70°C, as indicated by its 'C' temperature suffix. This range is validated per TI SLOS051E datasheet Section 4 (Recommended Operating Conditions) and applies to all electrical specifications unless otherwise noted. Operation outside this range may result in parametric degradation or functional failure.
Does the TLC27M2CPW support true single-supply operation with inputs referenced to ground?
Yes, the TLC27M2CPW supports true single-supply operation with inputs referenced to ground. Its common-mode input voltage range extends to −0.2 V below GND at VDD = 5 V (per datasheet page 5, VICR specification), enabling direct connection of grounded transducers without level-shifting circuitry - a key design advantage over standard op-amps.
What is the typical supply current consumption of the TLC27M2CPW at 5 V?
The TLC27M2CPW draws 210 µA typical supply current (IDD) for both amplifiers combined at VDD = 5 V, TA = 25°C, and no load (datasheet page 5, IDD parameter). This low quiescent current enables multi-year battery life in portable instrumentation and remote sensor nodes where power budget is constrained.
Is the TLC27M2CPW pin-compatible with other devices in the TLC27Mx family?
Yes, the TLC27M2CPW is pin-compatible with all TSSOP-8 variants in the TLC27Mx family, including TLC27M7CPW and TLC27M2ACPW. All share identical pinout (OUT A, IN− A, IN+ A, GND, VCC, OUT B, IN− B, IN+ B), allowing drop-in replacement for different offset voltage grades without PCB modification.
What packaging options are available for the TLC27M2CPW besides TSSOP-8?
The TLC27M2CPW is exclusively offered in the TSSOP-8 (PW) package. Other variants of the TLC27M2 - such as TLC27M2CP - use PDIP-8 (P), while TLC27M2CD uses SOIC-8 (D). No ceramic DIP (JG) or LCCC (FK) versions exist for the 'C' temperature grade with 500 µV offset; those are reserved for higher-offset grades or different temp ranges.
