Product details
Overview
TLC27L4IPWRG4 from Texas Instruments is a precision quad CMOS operational amplifier optimized for low-power, single-supply operation in sensor signal conditioning and industrial monitoring systems. It delivers 10 mV max input offset voltage (25°C), ultra-low 68 µA typical supply current (four amplifiers, VDD = 5 V), and rail-to-rail output swing down to the negative rail - enabling accurate analog front-end design in battery-powered field transmitters.
For engineers reviewing the TLC27L4IPWRG4 datasheet, TLC27L4IPWRG4 pinout, TLC27L4IPWRG4 application, or TLC27L4IPWRG4 equivalent, key selection criteria include its LinCMOS™ input stage (10¹² Ω input impedance, <1 pA bias current), extended common-mode range (–0.2 V to 3.5 V at VDD = 5 V), and guaranteed operation from –40°C to +85°C in TSSOP-14 packaging.
Technical Context
The TLC27L4IPWRG4 implements a silicon-gate LinCMOS™ architecture that combines bipolar-like precision (low VIO drift: 0.1 µV/month) with MOSFET-level power efficiency. Its input stage supports common-mode voltages extending below ground, while the output stage drives loads down to GND without saturation - critical for single-supply instrumentation interfaces.
Designed for stable operation with capacitive loads up to 20 pF, it features 85 kHz unity-gain bandwidth (VDD = 5 V), 34° phase margin, and 0.03 V/µs slew rate - balancing speed, stability, and low-noise (70 nV/√Hz at 1 kHz) for DC-coupled sensor amplification and active filtering.
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 without trimming |
| Supply Current (typ) | 68 µA for all four op amps at VDD = 5 V - enables multi-channel sensing in energy-constrained remote nodes |
| Input Impedance | 10¹² Ω typical - minimizes loading on high-Z sources like piezoresistive sensors and pH electrodes |
| Common-Mode Range | –0.2 V to 3.5 V at VDD = 5 V - allows direct interfacing to sub-ground-referenced transducer outputs |
| Output Swing (low) | 1 mV above GND (IOL = 0 mA) - supports full-scale ADC utilization in single-supply data acquisition |
| Unity-Gain Bandwidth | 85 kHz at VDD = 5 V - sufficient for anti-aliasing and low-frequency sensor signal conditioning (e.g., pressure, temperature) |
| ESD Rating | 2000 V per MIL-STD-883C, Method 3015.2 - ensures robustness during automated PCB assembly and field handling |

| 1OUT, 2OUT, 3OUT, 4OUT | Output (ch. 1–4) | Rail-to-rail capable: swings within 1 mV of GND and 0.9 V below VDD at light load |
| VDD | Positive power supply | Accepts 4 V to 16 V over –40°C to +85°C - supports wide-input industrial power rails |
| GND | Ground / negative supply | Reference for all inputs and outputs; common return for four independent amplifier sections |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad precision op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2464IPW | Lower VIO (1.6 mV max), higher supply current (550 µA), rail-to-rail I/O, 2.5 V min supply | Better DC precision but 8× higher power - suitable only where battery life is secondary to accuracy | Choose TLV2464IPW if VIO < 2 mV is mandatory and power budget allows ≥500 µA per device |
| LM324DR | Bipolar input (70 nA IB), higher VIO (7 mV typ), no sub-rail CMVR, 3 V min supply, wider temp range (–40°C to 125°C) | Higher power (1.4 mA), lower input impedance - acceptable for cost-sensitive, non-battery applications | Choose LM324DR for legacy designs or high-temp industrial use where LinCMOS benefits are not required |
Compared with TLV2464IPW, TLC27L4IPWRG4 trades precision for 8× lower power and true sub-ground input capability; compared with LM324DR, it delivers MOSFET-level input performance and single-supply flexibility at modest cost premium.

FAQ
What is the maximum operating temperature range for the TLC27L4IPWRG4?
The TLC27L4IPWRG4 is characterized for continuous operation from –40°C to +85°C, matching the I-suffix industrial temperature grade. This range is validated per TI's SLOS053E datasheet Section 5.3 and supports deployment in outdoor enclosures, factory floors, and automotive under-hood environments where thermal extremes occur.
Does the TLC27L4IPWRG4 support true single-supply operation with inputs below ground?
Yes - the TLC27L4IPWRG4 features a common-mode input voltage range extending to –0.2 V (at VDD = 5 V), verified in Section 5.4 of the datasheet. This allows direct connection to grounded-sensor outputs (e.g., strain gauges, thermocouples with cold-junction compensation) without external level-shifting circuitry.
What is the typical supply current for the TLC27L4IPWRG4 at 5 V?
The TLC27L4IPWRG4 draws 68 µA typical total supply current for all four amplifiers at VDD = 5 V and TA = 25°C, as specified in Section 5.4 Electrical Characteristics (C-suffix and I-suffix data). This ultra-low quiescent current enables multi-year battery life in wireless sensor nodes.
Is the TLC27L4IPWRG4 pin-compatible with other TLC27Lx variants?
Yes - all TLC27Lx quad op amps (including TLC27L4A, TLC27L4B, TLC27L9) share identical 14-pin TSSOP (PW) pinout and footprint per Figure 4-1 and Table 4-1. Designers may substitute grades based on VIO requirements without layout changes, provided thermal and supply constraints remain within spec.
