Product details
Overview
TLC27L2ID from Texas Instruments is a precision dual CMOS operational amplifier optimized for low-power, single-supply sensor signal conditioning. It delivers 10 mV max input offset voltage (25°C), ultra-low 34 µA typical supply current (VDD = 5 V), and rail-to-rail output swing down to the negative rail - enabling direct interfacing with transmitters in battery-powered field instrumentation.
For engineers reviewing the TLC27L2ID datasheet, TLC27L2ID pinout, TLC27L2ID application, or TLC27L2ID equivalent, key selection criteria include its LinCMOS™ input stage (10¹² Ω impedance, <60 pA bias current), −40°C to +85°C industrial temperature rating, and SOIC-8 package compatibility with legacy analog signal chains requiring precision, stability, and ESD-hardened operation.
Technical Context
The TLC27L2ID uses silicon-gate LinCMOS™ process technology to achieve exceptional input offset voltage stability (0.1 µV/month drift) and latch-up immunity, distinguishing it from conventional metal-gate CMOS op amps. Its input stage supports common-mode voltage down to −0.2 V (at VDD = 5 V), enabling true single-supply operation with ground-referenced sensors.
It features two independent amplifiers sharing one 5–16 V supply rail and ground reference, with internal ESD protection rated to 2000 V (MIL-STD-883C, Method 3015.2). The device exhibits 85 kHz unity-gain bandwidth and 34° phase margin at 25°C, ensuring stable closed-loop performance in active filters and transducer interface circuits without external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage (max) | 10 mV at 25°C - defines worst-case DC error in precision gain stages and sensor offset correction circuits |
| Supply Current (typ) | 34 µA at 25°C, VDD = 5 V - enables multi-year battery life in remote 4–20 mA loop-powered transmitters |
| Input Bias Current (max) | 60 pA at 25°C - preserves signal integrity when driving high-impedance sources like piezoelectric or pH electrodes |
| Common-Mode Input Range | −0.2 V to 3.5 V (VDD = 5 V) - allows direct connection to ground-referenced sensors without level-shifting circuitry |
| Output Swing (low) | ≤50 mV above GND (VDD = 5 V) - supports full-scale ADC utilization in single-supply data acquisition systems |
| Unity-Gain Bandwidth | 85 kHz at 25°C - sufficient for anti-aliasing filtering and low-frequency sensor signal amplification (e.g., pressure, temperature) |
| ESD Rating | 2000 V HBM - ensures robustness during PCB handling and field deployment in industrial environments |

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 |
|---|---|---|---|
| TLC27L2CD | Same electrical specs but rated for 0°C to 70°C commercial temperature range; lower cost | Not qualified for extended industrial environments; unsuitable for outdoor or uncontrolled-ambient deployments | Select TLC27L2CD only for cost-sensitive consumer or lab-grade equipment with controlled thermal conditions |
| TLV2462IDR | Higher drive strength (15 mA), rail-to-rail I/O, 6.5 V max supply, 23 µA IDD - but 3 mV VIO (max) and no MSL-1 moisture sensitivity rating | Better for higher-speed or higher-current analog front-ends; lacks long-term VIO stability and MIL-STD-883 ESD hardening | Choose TLV2462IDR when bandwidth >200 kHz or output current >10 mA is required, accepting trade-offs in drift and ruggedness |
Compared with TLC27L2CD and TLV2462IDR, the TLC27L2ID uniquely balances industrial temperature qualification, ultra-low drift, and proven ESD robustness - making it the preferred choice for field-deployed sensor interfaces where calibration stability and reliability outweigh raw speed or cost.

FAQ
What is the maximum operating temperature range for the TLC27L2ID?
The TLC27L2ID is specified for continuous operation from −40°C to +85°C. This industrial temperature grade is confirmed in Section 5.3 (Recommended Operating Conditions) and Table 5.8–5.11 of the SLOS052E datasheet. It supports deployment in outdoor enclosures, factory floors, and unheated utility cabinets where ambient extremes occur.
Does the TLC27L2ID support true single-supply operation with inputs extending below ground?
Yes, the TLC27L2ID supports common-mode input voltages down to −0.2 V (at VDD = 5 V), as verified in Section 5.3 and Table 5.4–5.15. This allows direct connection to ground-referenced sensors such as thermocouples or resistive bridges without external level-shifting circuitry - a key feature of its LinCMOS™ input architecture.
What is the typical supply current draw of the TLC27L2ID at 5 V?
The TLC27L2ID draws 34 µA typical supply current (two amplifiers) at VDD = 5 V and TA = 25°C, per Section 5.4 Electrical Characteristics. At −40°C, IDD rises to 31 µA (min), and at +85°C, it drops to 15 µA (min), confirming ultra-low power behavior across its full industrial temperature range.
Is the TLC27L2ID pin-compatible with other devices in the TLC27Lx family?
Yes, all TLC27Lx dual op amps - including TLC27L2ID, TLC27L2CD, TLC27L2AI, and TLC27L7I - use identical SOIC-8 (D), PDIP-8 (P), SOP-8 (PS), and TSSOP-8 (PW) packages with identical pinouts per Figure 4-1 and Table 4-1. This allows drop-in replacement for different offset voltage grades without PCB redesign.
What packaging options are available for the TLC27L2ID?
The TLC27L2ID is offered exclusively in the SOIC-8 (D) package, as confirmed in the Device Information table and Section 10 Mechanical, Packaging, and Orderable Information. It is supplied in tape-and-reel format for automated assembly, with moisture sensitivity level (MSL) rating appropriate for standard SMT reflow profiles.
