Product details
Overview
TLC27L4CPWRG4 from Texas Instruments is a precision quad operational amplifier in TSSOP-14 package, featuring 10 mV max input offset voltage (25°C), ultra-low 195 µW power consumption at 5 V, and rail-to-rail output swing down to the negative rail. It supports single-supply operation from 3 V to 16 V over 0°C–70°C and is optimized for low-power sensor signal conditioning in battery-powered field transmitters.
For engineers reviewing the TLC27L4CPWRG4 datasheet, TLC27L4CPWRG4 pinout, TLC27L4CPWRG4 application, or TLC27L4CPWRG4 equivalent, key selection criteria include input offset voltage stability (0.1 µV/month drift), high 10¹² Ω input impedance, common-mode input range extending below ground, and ESD protection rated to 2000 V per MIL-STD-883C Method 3015.2.
Technical Context
The TLC27L4CPWRG4 uses TI's LinCMOS™ silicon-gate process to achieve bipolar-like performance-high gain, low noise (70 nV/√Hz at 1 kHz), and excellent CMRR (65–87 dB)-without bipolar power penalties. Its four independent amplifiers share a single VDD and GND, with each channel supporting unity-gain stable operation and phase margin ≥30° across temperature.
Designed for single-supply systems, it enables true ground-sensing inputs (VICR down to –0.2 V) and rail-referenced outputs (VOL ≤ 50 mV at 0 mA load). Input bias current remains ultra-low (0.6 pA typ at 25°C), enabling high-impedance source interfacing without significant error.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage (max) | 10 mV at 25°C - sets worst-case DC error in precision gain stages and sensor bridges |
| Supply Current (typ) | 68 µA at 25°C - enables multi-year battery life in remote 4–20 mA loop-powered transmitters |
| Input Impedance | 10¹² Ω typical - preserves signal integrity when buffering high-Z sources like piezoresistive sensors |
| Common-Mode Input Range | –0.2 V to 3.5 V at VDD = 5 V - allows direct interface to grounded thermocouples or shunt-based current sensing |
| Unity-Gain Bandwidth | 85 kHz at VDD = 5 V - sufficient for anti-aliasing and low-frequency active filtering in industrial analog front-ends |
| ESD Rating | 2000 V HBM - ensures robustness during PCB handling and field deployment in unshielded environments |
| Slew Rate | 0.03 V/µs at VDD = 5 V - limits large-signal settling time but maintains stability with capacitive loads up to 20 pF |
Pinout & Package
Packaged in a 14-pin TSSOP (PW), the TLC27L4CPWRG4 features a compact 5 mm × 4.4 mm footprint with 0.65 mm pitch, suitable for space-constrained industrial PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1IN+, 2IN+, 3IN+, 4IN+ | Noninverting input (x4 channels) | Accepts high-impedance sensor signals; common-mode range extends below GND |
| 1IN–, 2IN–, 3IN–, 4IN– | Inverting input (x4 channels) | Used for feedback configuration; matched input bias minimizes offset error in differential setups |
| 1OUT, 2OUT, 3OUT, 4OUT | Output (x4 channels) | Rail-to-rail swing to GND enables full dynamic range utilization in single-supply systems |
| VDD | Positive supply | Single 3–16 V rail powers all four op-amps; IDD < 92 µA at 10 V ensures low quiescent dissipation |
| GND | Ground reference | Shared return path for all channels; internal ESD protection ties inputs to GND |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low power | 195 µW total at 5 V - reduces thermal drift and enables use in sealed, convection-limited enclosures |
| Latch-up immunity | Designed-in robustness against transient-induced CMOS latch-up - critical for field-deployed instrumentation |
| Offset voltage drift | 0.1 µV/month (including first 30 days) - ensures long-term calibration stability in maintenance-free installations |
| Single-supply optimization | Input and output operate near GND - eliminates need for dual supplies or level-shifting circuitry |
| High CMRR & PSRR | ≥65 dB CMRR and ≥70 dB PSRR - rejects noise from shared power rails and noisy industrial environments |

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 (2 mV max), higher supply current (550 µA), rail-to-rail I/O, wider bandwidth (6.4 MHz) | Better for higher-speed, higher-accuracy designs where power budget allows >2× increase | Select TLV2464IPW when faster settling and lower offset outweigh battery-life constraints |
| LM324DR | Higher VIO (7 mV typ), no guaranteed VIO max, higher IDD (1.4 mA), no ESD rating beyond 1500 V | Cost-sensitive general-purpose use; not recommended for calibrated sensor interfaces | Choose LM324DR only for non-critical, AC-coupled, or post-calibration applications with ample margin |
Compared with TLC27L4CPWRG4, TLV2464IPW delivers superior precision and speed at higher power cost, while LM324DR offers legacy compatibility and lower unit cost but lacks guaranteed offset, drift control, and robust ESD protection required for modern field instrumentation.

FAQ
What is the maximum operating temperature range for the TLC27L4CPWRG4?
The TLC27L4CPWRG4 is characterized for operation from 0°C to 70°C (C-suffix grade). Its absolute maximum junction temperature is 150°C, but continuous operation above 70°C requires derating per the 7.6 mW/°C dissipation factor for the TSSOP-14 package. The device is not rated for extended operation at –40°C or +85°C-those ranges apply only to I-suffix variants like TLC27L4IPWR.
Does the TLC27L4CPWRG4 support rail-to-rail input?
No-the TLC27L4CPWRG4 does not support rail-to-rail input. Its common-mode input voltage range extends to –0.2 V (below GND) and up to 3.5 V at VDD = 5 V, but it cannot accept signals at the positive rail. However, its output is rail-to-rail, swinging within 50 mV of GND and within 0.9 V of VDD under light load.
Can the TLC27L4CPWRG4 drive capacitive loads?
Yes-the TLC27L4CPWRG4 is unity-gain stable and tested with 20 pF capacitive loads. Phase margin remains ≥30° at 25°C with CL = 20 pF. For larger loads (>50 pF), external isolation resistance (e.g., 100 Ω in series with output) is recommended to maintain stability, as indicated in Figure 5-29 of the datasheet.
What is the input bias current specification for the TLC27L4CPWRG4?
The TLC27L4CPWRG4 has a typical input bias current of 0.6 pA at 25°C and a maximum of 600 pA at 70°C. This ultra-low value results from TI's LinCMOS™ process and enables accurate amplification of signals from high-impedance sources such as pH electrodes, photodiodes, and piezoelectric sensors without significant input error.
Is the TLC27L4CPWRG4 pin-compatible with other TLC27Lx variants?
Yes-the TLC27L4CPWRG4 shares identical pinout and package (TSSOP-14) with all other TLC27Lx variants offered in PW packaging, including TLC27L4APWR, TLC27L4BPWR, and TLC27L9PWR. Electrical differences (e.g., VIO grade, temperature range) do not affect mechanical or electrical connectivity, allowing drop-in substitution where specifications align.
