Product details
Overview
TLC27M2BIP from Texas Instruments is a dual precision operational amplifier using LinCMOS technology, designed for single-supply operation across −40°C to 85°C. It delivers 2 mV max input offset voltage at 25°C, 32 nV/√Hz input noise at 1 kHz, and 0.43 V/µs slew rate at VDD = 5 V - enabling accurate signal conditioning in battery-powered sensor interfaces and industrial analog front-ends.
For engineers reviewing the TLC27M2BIP datasheet, TLC27M2BIP pinout, TLC27M2BIP application, or TLC27M2BIP equivalent, key selection considerations include its rail-to-rail output swing, common-mode input range extending below ground, low 210 µA supply current per amplifier at 25°C, and guaranteed performance over extended temperature with I-suffix qualification.
Technical Context
The TLC27M2BIP implements a silicon-gate LinCMOS process that provides stable input offset voltage (drift ≤0.1 µV/month) and ultra-high input impedance (10¹² Ω typical), eliminating need for external biasing in high-impedance transducer applications. Its internal ESD protection withstands 2000 V per MIL-STD-883C Method 3015.2.
Designed for single-supply use, the device supports common-mode input voltage down to −0.2 V (at VDD = 5 V) and output swing to within 50 mV of GND. It exhibits 91 dB CMRR and 93 dB PSRR at 25°C, making it suitable for noisy industrial environments where supply rejection and interference immunity are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | 2 mV max at 25°C - enables DC-coupled amplification without significant baseline error in 12-bit ADC front-ends |
| Supply Voltage Range | 4 V to 16 V over −40°C to 85°C - supports wide-input industrial power rails and battery systems down to 4 V |
| Input Bias Current | 0.6 pA typical at 25°C - preserves signal integrity in photodiode and piezoelectric sensor interfaces |
| Slew Rate | 0.43 V/µs at VDD = 5 V - sufficient for <50 kHz small-signal bandwidth in unity-gain buffer configurations |
| Common-Mode Input Range | Extends to −0.2 V below GND at VDD = 5 V - allows direct interfacing with bipolar signals in single-supply systems |
| Output Voltage Swing | Within 50 mV of GND and within 100 mV of VDD - ensures full dynamic range utilization with 3.3 V or 5 V logic-compatible outputs |
| Supply Current (dual) | 210 µA typical at 25°C, VDD = 5 V - enables multi-year operation in low-power remote monitoring nodes |
Pinout & Package
Package: 8-pin plastic DIP (P package), through-hole mounting, JEDEC MS-001 compatible.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Inverting amplifier output - drives loads up to ±30 mA; rail-to-rail swing supports full-scale analog output |
| 2 | IN− A | Inverting input - high-impedance node (10¹² Ω); requires matched trace impedance for optimal CMRR |
| 3 | IN+ A | Non-inverting input - accepts signals down to −0.2 V below GND; used for reference-biased sensor inputs |
| 4 | GND | Analog ground reference - must be star-connected to minimize ground bounce in mixed-signal PCB layouts |
| 5 | VCC | Positive supply - decoupling capacitor (0.1 µF ceramic) required within 5 mm for stability at unity gain |
| 6 | OUT B | Second amplifier output - independent channel enables dual-path signal conditioning without cross-talk |
| 7 | IN− B | Inverting input for second op-amp - electrically isolated from Channel A; supports differential pair configurations |
| 8 | IN+ B | Non-inverting input for second op-amp - identical electrical characteristics to Pin 3; enables matched dual-channel design |
Key Features
| Feature | Design Value |

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 |
|---|---|---|---|
| TLC27M2CP | Same electrical specs but rated for 0°C to 70°C only; P-package identical; no thermal derating required below 70°C | Restricted to commercial-temperature applications (e.g., consumer electronics, office equipment) | Select when ambient operating temperature remains above 0°C and cost optimization is prioritized over extended temp range |
| TLV272IP | Lower VIO (2.5 mV max), higher supply current (1.25 mA), rail-to-rail input/output, same −40°C to 85°C rating | Better input/output swing but higher power draw limits use in ultra-low-power designs | Choose when full rail-to-rail input capability is required and system can accommodate ~6× higher quiescent current |
Compared with TLC27M2CP, the TLC27M2BIP adds guaranteed −40°C startup and long-term drift stability for industrial deployment; versus TLV272IP, it trades rail-to-rail input for 5.9× lower supply current - critical for energy-constrained edge sensors.

FAQ
What is the maximum input offset voltage specification for TLC27M2BIP over its full operating temperature range?
The TLC27M2BIP has a maximum input offset voltage of 3000 µV (3 mV) across the full −40°C to 85°C operating range, as specified in the "electrical characteristics" table for VDD = 5 V and full temperature range testing conditions. At 25°C only, the limit is tighter: 2000 µV (2 mV). This graded specification reflects thermal drift behavior inherent to LinCMOS process technology.
Can TLC27M2BIP operate from a single 3.3 V supply?
No, TLC27M2BIP cannot operate reliably from a single 3.3 V supply. Its minimum recommended supply voltage is 4 V across the −40°C to 85°C range, as defined in the "recommended operating conditions" table. Operation below 4 V risks degraded output swing, reduced CMRR, and potential failure to meet AC specifications such as slew rate and bandwidth.
Does TLC27M2BIP support rail-to-rail input operation?
No, TLC27M2BIP does not support rail-to-rail input. Its common-mode input voltage range extends to −0.2 V below GND (at VDD = 5 V) but only up to 3.5 V - i.e., 1.5 V below VDD. It is rail-to-rail on the output side (within 50 mV of GND and within 100 mV of VDD), but input range is limited, distinguishing it from modern RRO op-amps like TLV272IP.
What package type is used for TLC27M2BIP, and is it RoHS-compliant?
TLC27M2BIP uses the 8-pin plastic DIP (P) package, per JEDEC MS-001 standard. While the original datasheet predates RoHS, Texas Instruments confirms this part is manufactured in RoHS-compliant facilities and meets lead-free soldering requirements (reflow profile peak 260°C for 10 seconds). Full compliance documentation is available under TI's PCN archives.
How does the input bias current of TLC27M2BIP compare to bipolar op-amps, and why does it matter?
TLC27M2BIP features an input bias current of just 0.6 pA typical at 25°C - over six orders of magnitude lower than typical bipolar op-amps (e.g., LM358: ~45 nA). This enables direct connection to high-impedance sources like pH electrodes, photodiodes, and piezoelectric sensors without signal loss or DC error from bias current flowing through source resistance.
