Product details
Overview
TLC27L2AIDR from Texas Instruments is a precision dual CMOS operational amplifier optimized for ultra-low-power, single-supply operation in sensor signal conditioning and industrial monitoring systems. It delivers 5 mV max input offset voltage at 25°C, 10¹² Ω typical input impedance, 95 μW typical power consumption at 5 V, and rail-to-rail output swing capability with common-mode input extending below ground.
For engineers reviewing the TLC27L2AIDR datasheet, TLC27L2AIDR pinout, TLC27L2AIDR application, or TLC27L2AIDR equivalent, key selection considerations include its −40°C to +85°C industrial temperature range, SOIC-8 package, LinCMOS™ process stability, and suitability for battery-powered transducer interfaces requiring low drift and high DC accuracy.
Technical Context
The TLC27L2AIDR uses Texas Instruments' silicon-gate LinCMOS™ process to achieve exceptional input offset voltage stability (0.1 μV/month drift) and ultra-low input bias currents (sub-1 pA typical). Its architecture supports single-supply operation down to 4 V over the full −40°C to +85°C range while maintaining rail-inclusive common-mode input (−0.2 V to VDD − 1.5 V) and rail-swing output.
It features internal ESD protection rated to 2000 V (MIL-STD-883C, Method 3015.2), latch-up immunity, and operates with supply rejection >70 dB and CMRR >65 dB across temperature - enabling robust performance in noisy industrial environments without external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | 5 mV max at 25°C - enables accurate DC-coupled amplification of microvolt-level sensor outputs without trimming. |
| Supply Voltage Range | 4 V to 16 V over −40°C to +85°C - supports direct interface with 5 V or 12 V industrial rails and battery-backed systems. |
| Input Impedance | 10¹² Ω typical - minimizes loading on high-impedance sources like piezoresistive bridges and pH electrodes. |
| Quiescent Current | 20–34 µA per amplifier at 25°C - allows continuous operation for years on coin-cell batteries in remote field transmitters. |
| Common-Mode Input Range | Extends to −0.2 V below ground - permits true single-supply operation with inputs referenced to system ground. |
| Output Voltage Swing | Within 50 mV of rails at light load - maximizes dynamic range in low-voltage data acquisition front-ends. |
| Unity-Gain Bandwidth | 85 kHz at VDD = 5 V - sufficient for anti-aliasing, filtering, and buffering of slow-varying process signals (e.g., pressure, temperature). |
Pinout & Package
Package: 8-pin SOIC (D), tape-and-reel format, body width 3.9 mm, standard JEDEC MS-012AC footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1IN+ | Noninverting input, Channel 1 | High-impedance node for differential sensing; accepts signals down to −0.2 V relative to GND. |
| 1IN− | Inverting input, Channel 1 | Feedback node for closed-loop configurations; matched to 1IN+ for precision gain setting. |
| 1OUT | Output, Channel 1 | Capable of sourcing/sinking ±30 mA; swings within 50 mV of VDD/GND under light load. |
| GND | Ground reference | System return path; serves as negative supply rail in single-supply operation. |
| 2IN+ | Noninverting input, Channel 2 | Independent high-Z input for second sensor channel or reference buffer. |
| 2IN− | Inverting input, Channel 2 | Separate feedback node; electrically isolated from Channel 1 for dual-path signal processing. |
| VDD | Positive supply | Accepts 4–16 V; powers both amplifiers; internal regulation ensures stable bias over supply variation. |
| NC | No connect | Pin 8 is not bonded; no electrical function - must remain unconnected per TI design. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low power consumption | 95 μW typical at 5 V - extends battery life in wireless sensor nodes and portable instrumentation. |
| Input offset voltage drift | 0.1 μV/month including first 30 days - eliminates need for periodic recalibration in long-term field deployments. |
| ESD protection | 2000 V HBM rating - withstands handling and board assembly without external protection diodes. |
| Latch-up immunity | Designed-in robustness against transient-induced parasitic conduction - improves reliability in harsh EMI environments. |
| Single-supply operation | Valid down to 4 V with rail-inclusive inputs - simplifies power architecture by eliminating split supplies in analog front-ends. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision dual op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2462IDR | Higher drive strength (15 mA), higher supply current (550 µA), rail-to-rail I/O, but 3 mV VIO max - less precise DC gain accuracy. | Better for driving capacitive loads or ADC drivers; unsuitable where ultra-low power (<100 µA) is mandatory. | Select when output drive or rail-to-rail input is prioritized over micropower and ultra-low offset. |
| OPA2333AIDR | Zero-drift architecture, 12 µV VIO max, 17 µA per amp, but requires ≥1.8 V supply - incompatible with 4 V minimum requirement. | Superior for sub-µV offset needs in medical or test equipment; cannot operate from 4–5 V industrial rails. | Select only if supply can be lowered to 1.8–5.5 V and zero-drift performance justifies cost and layout complexity. |
Compared with TLV2462IDR and OPA2333AIDR, the TLC27L2AIDR uniquely balances ultra-low power (≤34 µA), 4 V minimum supply, and 5 mV precision in an industrial-temperature SOIC-8 - making it optimal for legacy-compatible, battery-constrained field transmitter upgrades.
