Product details
Overview
TLC27L4IPWR from Texas Instruments is a precision quad operational amplifier using LinCMOS™ technology, designed for ultra-low-power, single-supply sensor signal conditioning. It delivers 10 mV max input offset voltage (25°C), 195 µW typical power consumption at 5 V, and rail-to-rail output swing with common-mode input extending below ground. It is used in battery-powered field transmitters including pressure, temperature, and flow sensors.
For engineers reviewing the TLC27L4IPWR datasheet, TLC27L4IPWR pinout, TLC27L4IPWR application, or TLC27L4IPWR equivalent, key selection criteria include its 10 mV VIO grade, TSSOP-14 package, –40°C to +85°C industrial temperature range, and compatibility with low-voltage (4–16 V) single-supply operation in high-impedance analog front-ends.
Technical Context
The TLC27L4IPWR implements a silicon-gate LinCMOS™ input stage enabling 1012 Ω input impedance and sub-picoampere bias currents (0.6 pA typ), while maintaining latch-up immunity and integrated ESD protection rated to 2000 V (MIL-STD-883C). Its architecture supports stable unity-gain operation with 34° phase margin and 85 kHz bandwidth at 5 V supply.
It operates across 4 V to 16 V supply rails with a common-mode input range of –0.2 V to 3.5 V (at 5 V) and output swing from GND to within 50 mV of VDD, making it suitable for direct interfacing with microcontroller ADCs and low-voltage reference circuits without level-shifting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VIO max (25°C) | 10 mV - defines worst-case DC error in precision gain stages; impacts offset-critical applications like bridge sensor amplification |
| Supply voltage range | 4 V to 16 V - enables direct use with 5 V, 9 V, or 12 V industrial supplies and battery stacks without regulation |
| IDD (4 amps, 25°C) | 39–68 µA - allows continuous operation for >10 years on a single CR2032 coin cell in low-duty-cycle sensor nodes |
| Input impedance | 1012 Ω - prevents loading of high-Z sources such as piezoelectric sensors, pH electrodes, and thermistors |
| Common-mode range | –0.2 V to 3.5 V (VDD = 5 V) - supports true single-supply operation with inputs referenced to ground |
| Output swing | GND to VDD – 50 mV - delivers full dynamic range to 12-bit ADCs without external level-shifting circuitry |
| Unity-gain bandwidth | 85 kHz (25°C, VDD = 5 V) - sufficient for anti-aliasing and sensor signal filtering up to ~10 kHz |
Pinout & Package
Packaged in a 14-pin TSSOP (PW), the TLC27L4IPWR provides compact footprint (5.0 × 4.4 mm) and thermal performance suited for space-constrained industrial modules and portable instrumentation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1IN+, 2IN+, 3IN+, 4IN+ | Noninverting input (x4 channels) | High-impedance node for reference or sensor signal connection; accepts voltages down to –0.2 V |
| 1IN–, 2IN–, 3IN–, 4IN– | Inverting input (x4 channels) | Feedback or differential sensing node; matched to noninverting input for CMRR optimization |
| 1OUT, 2OUT, 3OUT, 4OUT | Amplifier output (x4 channels) | Rail-to-rail capable output driving loads ≥1 MΩ; limited to ±30 mA short-circuit current |
| VDD (Pin 4) | Positive supply | Accepts 4–16 V; must be decoupled locally with 0.1 µF ceramic capacitor |
| GND (Pin 11) | Ground reference | System return path; serves as negative rail for single-supply operation and common-mode baseline |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low quiescent power | 195 µW typical at 5 V - enables always-on monitoring in energy-harvesting and battery-backed systems |
| Input offset drift | 0.1 µV/month - ensures long-term calibration stability in field-deployed instrumentation |
| ESD protection | 2000 V HBM - reduces need for external transient suppression in industrial I/O modules |
| Latch-up immunity | Designed-in robustness - prevents catastrophic failure during overvoltage or hot-plug events |
| Single-supply optimized | Common-mode range extends below GND - eliminates dual-rail requirement for sensor biasing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2464IPWR | Lower VIO (2 mV max), higher IDD (520 µA), rail-to-rail I/O, 1.5 MHz GBW | Better precision and speed but 2.7× higher power; requires 2.7–6 V supply | Select when higher bandwidth and lower offset outweigh battery-life constraints |
| LM324DR | Higher VIO (7 mV typ), bipolar input (65 nA IIB), no ESD rating, 1.2 MHz GBW | Cost-optimized general-purpose part; lacks LinCMOS low-power and high-Z advantages | Select for non-battery, non-high-Z applications where cost dominates and 40 µA quiescent current is acceptable |
Compared with TLV2464IPWR, TLC27L4IPWR trades bandwidth and offset for 13× lower supply current-critical for multi-year battery operation. Versus LM324DR, it delivers 1000× lower input bias current and integrated ESD protection, enabling reliable interfacing with high-impedance sensors in harsh environments.
