Product details
Overview
TLC27L2IPWR 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 accurate amplification in battery-powered field transmitters and smoke detectors.
For engineers reviewing the TLC27L2IPWR datasheet, TLC27L2IPWR pinout, TLC27L2IPWR application, or TLC27L2IPWR equivalent, key selection criteria include its −40°C to +85°C industrial temperature rating, LinCMOS™ input impedance of 10¹² Ω, common-mode input range extending below ground, and compatibility with 4–16 V single-supply operation in remote analog front-ends.
Technical Context
The TLC27L2IPWR uses Texas Instruments' silicon-gate LinCMOS™ process to achieve stable input offset voltage (drift ≤0.1 µV/month) and high DC precision without bipolar power penalties. Its dual-channel architecture supports independent signal paths with matched gain and offset characteristics across temperature.
It operates with true single-supply capability: the common-mode input voltage includes the negative rail (−0.2 V at VDD = 5 V), and output swings to within 50 mV of GND. Internal ESD protection meets MIL-STD-883C, Method 3015.2 (2000 V HBM).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage (max) | 10 mV at 25°C - sets baseline DC error in precision sensor gain stages |
| Supply Current (typ) | 34 µA at VDD = 5 V - enables multi-year battery life in wireless field transmitters |
| Input Impedance | 10¹² Ω - prevents loading of high-impedance sources like piezoresistive sensors |
| Common-Mode Input Range | −0.2 V to 3.5 V (VDD = 5 V) - allows direct interface to grounded sensors |
| Output Swing (low) | ≤50 mV above GND - supports full-scale ADC utilization in single-supply systems |
| Unity-Gain Bandwidth | 85 kHz at VDD = 5 V - sufficient for DC–10 kHz industrial sensor signals |
| ESD Rating | 2000 V HBM - reduces handling sensitivity in manufacturing and field service |
Pinout & Package
Packaged in an 8-pin TSSOP (PW), the TLC27L2IPWR provides compact surface-mount integration with thermal and space efficiency for dense PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1IN+ | Noninverting input, Channel 1 | High-impedance node for differential or single-ended signal routing |
| 1IN− | Inverting input, Channel 1 | Feedback path connection point; matched to 1IN+ for CMRR optimization |
| 1OUT | Output, Channel 1 | Capable of sourcing/sinking ±30 mA; swings to within 50 mV of GND |
| GND | Ground reference | Low-impedance return for both channels; must be star-connected in mixed-signal designs |
| 2IN+ | Noninverting input, Channel 2 | Independent high-Z input for second sensor or reference channel |
| 2IN− | Inverting input, Channel 2 | Enables dual-channel instrumentation or active filtering without cross-talk |
| VDD | Positive supply | Accepts 4–16 V; internal regulation not required for stable biasing |
| NC | No connect | Pin 8 is unused; no internal connection - leave unconnected or grounded per layout best practice |
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 |
|---|---|---|---|
| TLC27L2CPW | Same electrical specs but rated for 0°C to 70°C (C-suffix); TSSOP-8 package identical | Not qualified for industrial temperature range; unsuitable for outdoor or factory-floor deployment | Select TLC27L2IPWR when operating ambient exceeds 70°C or drops below 0°C |
| TLV2462IDR | Lower VIO (2 mV max), higher IDD (550 µA typ), rail-to-rail I/O, SOIC-8 only | Higher power consumption limits battery use; superior DC precision suits metrology-grade designs | Choose TLV2462IDR only if VIO < 2 mV is mandatory and power budget allows ≥500 µA per amplifier |
Compared with TLC27L2CPW, the TLC27L2IPWR adds guaranteed −40°C to +85°C operation without changing footprint or pinout; versus TLV2462IDR, it trades 8× lower quiescent current for relaxed offset spec - making it optimal for energy-constrained industrial sensing where 10 mV VIO is acceptable.

FAQ
What is the maximum supply voltage for the TLC27L2IPWR?
The TLC27L2IPWR supports a maximum supply voltage of 16 V under recommended operating conditions. Absolute maximum rating is 18 V, but continuous operation above 16 V risks parametric degradation and reduced reliability. This 4–16 V range enables direct use with standard 5 V, 12 V, and 24 V industrial rails - critical for the TLC27L2IPWR's role in field transmitters and sensor interfaces.
Does the TLC27L2IPWR support true single-supply operation with inputs below ground?
Yes, the TLC27L2IPWR supports true single-supply operation with its common-mode input voltage range extending to −0.2 V (at VDD = 5 V), i.e., 200 mV below the negative rail (GND). This allows direct connection of grounded sensors such as thermocouples or bridge circuits without level-shifting - a core design feature confirmed in Section 5.3 of the TLC27L2IPWR datasheet.
What is the typical supply current of the TLC27L2IPWR at 5 V?
The TLC27L2IPWR draws 34 µA typical supply current (two amplifiers) at VDD = 5 V and TA = 25°C, rising to 42 µA at 0°C and falling to 26 µA at 85°C. This ultra-low quiescent current is fundamental to its use in battery-powered field devices - for example, enabling multi-year operation in wireless pressure transmitters powered by CR2032 cells.
Is the TLC27L2IPWR pin-compatible with other TLC27Lx variants in TSSOP-8?
Yes, all TLC27Lx devices in the PW (TSSOP-8) package - including TLC27L2IPWR, TLC27L2APWR, TLC27L2BPWR, and TLC27L7PWR - share identical pinout, footprint, and thermal pad configuration. The only differences are input offset voltage grade and temperature rating; no PCB redesign is needed when upgrading within the same package suffix.
What does the 'I' suffix in TLC27L2IPWR indicate?
The 'I' suffix in TLC27L2IPWR denotes industrial temperature range qualification: −40°C to +85°C. This distinguishes it from the 'C' (0°C to 70°C) and 'M' (−55°C to +125°C) variants. All electrical specifications in the TLC27L2IPWR datasheet - including VIO ≤10 mV, IDD ≤46 µA, and VICR - are guaranteed across this full industrial range, making it suitable for factory automation and outdoor environmental monitoring.
