Product details
Overview
TLC27M2BIDR from Texas Instruments is a dual precision operational amplifier using LinCMOS technology, designed for single-supply operation with rail-to-rail input (extends below negative rail) and output swing to negative rail. 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 high-accuracy signal conditioning in battery-powered sensor interfaces and industrial analog front-ends.
For engineers reviewing the TLC27M2BIDR datasheet, TLC27M2BIDR pinout, TLC27M2BIDR application, or TLC27M2BIDR equivalent, key selection criteria include its −40°C to 85°C industrial temperature range, low 210–560 µA supply current per amplifier pair, high 10¹² Ω input impedance, and compatibility with 4–16 V supply rails - critical for low-power, wide-voltage-range analog systems.
Technical Context
The TLC27M2BIDR implements a silicon-gate LinCMOS process that achieves superior input offset voltage stability versus metal-gate alternatives, with typical drift of only 0.1 µV/month including first 30 days. Its architecture supports common-mode input voltage down to −0.2 V (at VDD = 5 V), enabling true single-supply transducer interfacing without level-shifting circuitry.
It features internal ESD protection rated to 2000 V (MIL-STD-883C, Method 3015.2), latch-up immunity, and robust absolute maximum ratings - including ±30 mA output current and 18 V supply voltage tolerance - making it suitable for harsh industrial environments where reliability under transient stress is essential.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | 2 mV max at 25°C; ensures ≤2 mV DC error in precision gain stages without trimming. |
| Supply Voltage Range | 4 V to 16 V over −40°C to 85°C; supports direct connection to 5 V, 9 V, or 12 V rails without regulation. |
| Input Bias Current | 0.6 pA typ at 25°C; enables high-impedance sensor buffering (e.g., pH electrodes, piezoresistive bridges) with minimal loading. |
| Slew Rate | 0.43 V/µs at VDD = 5 V; sufficient for <50 kHz small-signal bandwidth in unity-gain configurations. |
| Common-Mode Input Range | Extends to −0.2 V below GND at VDD = 5 V; allows direct interface with ground-referenced sensors in single-supply systems. |
| Output Voltage Swing | Includes negative rail (VOL ≤ 50 mV at IOL = 0); simplifies level-sensitive comparator or reference buffer designs. |
| Input Noise Density | 32 nV/√Hz at f = 1 kHz; limits added noise in low-frequency instrumentation amplifiers and sensor signal chains. |
Pinout & Package
Package: SOIC-8 (D package), tape-and-reel (R suffix), 3.9 mm × 4.9 mm body, 1.27 mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| 2 | Non-inverting input of amplifier A | Reference or sensor input node; supports common-mode voltages down to −0.2 V (VDD = 5 V). |
| 3 | Output of amplifier A | Capable of sourcing/sinking ±30 mA; drives 100 kΩ loads with ≤50 mV low-level swing. |
| 4 | Ground (GND) | Return path for both amplifiers; must be low-impedance to minimize PSRR degradation. |
| 5 | Non-inverting input of amplifier B | Independent input channel; identical electrical specs to Pin 2. |
| 6 | Inverting input of amplifier B | Independent input channel; identical electrical specs to Pin 1. |
| 7 | Output of amplifier B | Independent output channel; identical drive capability to Pin 3. |
| 8 | Positive supply (VCC) | Accepts 4–16 V; decoupling capacitor (0.1 µF ceramic) required within 1 cm for stability. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual precision operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV272IDR | Lower 1.5 mV max offset (I-suffix), 0.35 V/µs slew rate, 1.8–16 V supply, but higher 550 µA supply current. | Better offset spec but reduced speed and higher power - suited for ultra-low-offset DC apps where bandwidth <30 kHz suffices. | Select TLV272IDR when offset <1.5 mV is mandatory and power budget allows +100 µA per amplifier. |
| LMV358IDR | Higher 3 mV max offset, rail-to-rail output only (not input), 1.0 V/µs slew rate, 2.7–5.5 V supply - incompatible above 5.5 V. | Optimized for 3.3 V systems only; cannot replace TLC27M2BIDR in 9 V or 12 V industrial supplies. | Choose LMV358IDR only for cost-sensitive 3.3 V consumer electronics - not for industrial 4–16 V use cases. |
Compared with TLV272IDR and LMV358IDR, the TLC27M2BIDR uniquely balances 2 mV offset, 4–16 V operation, rail-to-rail input, and sub-600 µA quiescent current - making it the sole option among the three for wide-supply, low-drift, low-power industrial analog front-ends.

FAQ
What is the maximum input offset voltage specification for TLC27M2BIDR at 25°C?
The TLC27M2BIDR has a maximum input offset voltage of 2 mV at 25°C, as specified in the "Electrical Characteristics" table for the I-suffix grade under VDD = 5 V test conditions. This value is guaranteed across production lots and applies to both amplifiers in the dual package.
Does TLC27M2BIDR support true single-supply operation with input signals below ground?
Yes, the TLC27M2BIDR supports common-mode input voltages down to −0.2 V (at VDD = 5 V) and −0.2 V (at VDD = 10 V), extending below the negative rail (GND). This rail-to-rail input capability enables direct interfacing with ground-referenced sensors without external level-shifting circuitry.
What is the supply voltage range for TLC27M2BIDR over its full operating temperature range?
The TLC27M2BIDR operates from 4 V to 16 V across its full −40°C to 85°C industrial temperature range. This wide supply range allows direct integration into systems powered by unregulated 5 V, 9 V, or 12 V rails without intermediate regulation.
How does the input bias current of TLC27M2BIDR impact high-impedance sensor interfacing?
The TLC27M2BIDR exhibits a typical input bias current of 0.6 pA at 25°C, enabling accurate amplification of signals from high-impedance sources such as pH electrodes, piezoresistive sensors, or photodiode transimpedance stages without significant DC error or signal attenuation.
Is TLC27M2BIDR pin-compatible with other devices in the TLC27Mx family?
Yes, all TLC27Mx dual op-amps - including TLC27M2BIDR, TLC27M2CDR, and TLC27M7IDR - share identical SOIC-8 (D) pinouts and package dimensions. This allows drop-in replacement between grades (e.g., upgrading from 2 mV to 500 µV offset) without PCB redesign.
