Texas Instruments TLC27M2BID

Overview

TLC27M2BID from Texas Instruments is a dual precision operational amplifier using LinCMOS technology, designed for industrial temperature range (−40°C to 85°C), with 2 mV max input offset voltage at 25°C, 32 nV/√Hz input noise at 1 kHz, and rail-to-rail output swing down to GND - ideal for low-power sensor signal conditioning in battery-powered instrumentation.

For engineers reviewing the TLC27M2BID datasheet, TLC27M2BID pinout, TLC27M2BID application, or TLC27M2BID equivalent, key selection criteria include its guaranteed 2 mV V_IO over full temperature range, single-supply operation from 4 V to 16 V, high 10¹² Ω input impedance, ESD protection up to 2000 V, and compatibility with legacy TLC27x designs requiring extended temperature performance.

Technical Context

The TLC27M2BID implements a silicon-gate LinCMOS process enabling stable offset voltage drift (typically 0.1 µV/month) and ultra-low input bias current (0.6 pA typ at 25°C). Its architecture supports common-mode input voltage extending below the negative rail, enabling true single-supply transducer interfacing without level-shifting circuitry.

It delivers 0.43 V/µs slew rate and 525 kHz unity-gain bandwidth at V_DD = 5 V, with phase margin of 40° - sufficient for stable closed-loop operation in active filters and precision gain stages while consuming only 210 µA per amplifier (420 µA total) at 25°C.

The following parts are listed as comparable options for similar dual precision op-amp applications.

Compared with TLV272IDR and LMV358IDR, the TLC27M2BID uniquely balances moderate offset (2 mV), ultra-low bias current (0.6 pA), and industrial temperature rating - making it optimal for long-lifetime, uncalibrated sensor nodes where leakage and thermal drift dominate error budgets.

Availability

TLC27M2BID is available at Aetrix Electronics and suitable for industrial sensor signal conditioning, portable battery-powered instrumentation, medical patient monitoring, and automotive cabin environment sensing requiring stable component supply across extended temperature ranges and multi-year production cycles.

Supply support for TLC27M2BID includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

Manufacturer

Texas Instruments is a global semiconductor company headquartered in Dallas, Texas, delivering analog and embedded processing solutions since 1930.

The TLC27Mx series was developed to provide LinCMOS-based precision op-amps with superior offset stability, low power, and single-supply capability - targeting industrial, medical, and instrumentation applications where reliability and long-term parametric consistency are critical.

FAQ

What is the maximum input offset voltage specification for TLC27M2BID over its full operating temperature range?

The TLC27M2BID has a maximum input offset voltage of 3 mV over the full −40°C to +85°C operating range, with a tighter 2 mV limit specified at 25°C. This graded specification ensures predictable DC error in precision analog front-ends without requiring system-level trimming, especially in industrial environments where ambient temperature varies widely.

Can TLC27M2BID operate from a single 3.3 V supply?

No, the TLC27M2BID requires a minimum supply voltage of 4 V across its rated −40°C to +85°C temperature range. At 3.3 V, the device falls outside its recommended operating conditions and may exhibit degraded parameters including reduced output swing, increased offset voltage, and instability. For 3.3 V systems, consider the TLV272 or LMV358 families instead.

Does TLC27M2BID support rail-to-rail input common-mode voltage?

The TLC27M2BID supports common-mode input voltage down to −0.2 V below GND (i.e., extends below the negative rail), but does not support rail-to-rail input - the upper limit is V_DD − 1.5 V at 25°C. This design enables true single-supply operation with grounded sensors while maintaining robustness against input overvoltage transients.

What is the typical input bias current of TLC27M2BID at 85°C?

The typical input bias current of TLC27M2BID at 85°C is 200 pA, with a maximum of 2000 pA. This ultra-low value - enabled by LinCMOS gate oxide technology - ensures minimal voltage error across high-value feedback networks (e.g., 10 MΩ resistors contribute <2 mV error), critical for precision integrators and high-gain sensor interfaces.

Is TLC27M2BID pin-compatible with other devices in the TLC27Mx family?

Yes, all TLC27Mx dual op-amps in SOIC-8 (D) package - including TLC27M2BID, TLC27M2CD, TLC27M7ID, and TLC27M2AID - share identical pinout and footprint. This allows direct substitution within the same package variant for offset grade upgrades or temperature range changes without PCB redesign.
