Product details
Overview
TLC27L4CPW from Texas Instruments is a precision quad CMOS operational amplifier in TSSOP-14 package, optimized for single-supply operation with 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 - enabling use in battery-powered sensor signal conditioning and industrial transmitter front-ends.
For engineers reviewing the TLC27L4CPW datasheet, TLC27L4CPW pinout, TLC27L4CPW application, or TLC27L4CPW equivalent, this page delivers verified specifications, validated pin functions, confirmed operating conditions (0°C to 70°C, 3–16 V supply), and real-world design context for low-power analog signal processing in field transmitters and remote sensing systems.
Technical Context
The TLC27L4CPW implements LinCMOS™ silicon-gate technology to achieve high input impedance (10¹² Ω typical), sub-picoampere input bias current (0.6 pA typ at 25°C), and latch-up immunity - distinguishing it from bipolar op amps while avoiding their power penalties. Its common-mode input range extends 0.2 V below ground, supporting true single-supply interfacing with grounded sensors.
It delivers stable unity-gain bandwidth (85 kHz typ at 5 V), 34° phase margin, and low 70 nV/√Hz input noise - making it suitable for DC-coupled amplification and low-frequency active filtering where precision, stability, and minimal quiescent current are critical.
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 per amplifier (272 µA total) at 25°C - enables multi-channel operation on microamp-level power budgets |
| Input Bias Current (typ) | 0.6 pA at 25°C - permits high-impedance sensor interfaces (e.g., pH electrodes, piezoresistive bridges) without loading error |
| Common-Mode Input Range | Extends to –0.2 V below GND - supports direct connection of grounded-signal sources in single-supply systems |
| Output Voltage Swing | Down to GND (low-level output ≤ 50 mV at 25°C) - ensures full dynamic range utilization with unipolar supplies |
| Unity-Gain Bandwidth | 85 kHz at VDD = 5 V - sufficient for <10 kHz sensor signal bandwidths with stable closed-loop response |
| ESD Rating | 2000 V per MIL-STD-883C Method 3015.2 - provides robust handling during PCB assembly and field service |
Pinout & Package
TSSOP-14 (PW) package: 4.4 mm × 5.0 mm body, 0.65 mm pitch, exposed pad not electrically connected; RoHS-compliant, moisture-sensitive level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1IN+, 2IN+, 3IN+, 4IN+ | Noninverting inputs (ch1–ch4) | High-impedance nodes accepting sensor or reference signals; tolerate common-mode voltages down to –0.2 V |
| 1IN–, 2IN–, 3IN–, 4IN– | Inverting inputs (ch1–ch4) | Accept feedback or differential inputs; matched with noninverting inputs for common-mode rejection |
| 1OUT, 2OUT, 3OUT, 4OUT | Amplifier outputs (ch1–ch4) | Capable of sourcing/sinking ±30 mA; swing to GND and up to VDD – 1.1 V (at 5 V) |
| VDD | Positive supply | Accepts 3–16 V over 0°C to 70°C; internal regulation not required |
| GND | Ground / negative supply | Reference for all inputs and outputs; common return for four channels |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low power | 195 µW total quiescent power at 5 V - extends battery life in portable field instruments beyond 10 years |
| Rail-to-rail output | Output swings to GND (≤50 mV low-level) and within 1.1 V of VDD - maximizes ADC input range in 3.3 V or 5 V systems |
| Single-supply optimized | Common-mode input includes negative rail (–0.2 V) - eliminates need for dual supplies or level-shifting circuitry |
| High input impedance | 10¹² Ω typical - prevents loading of high-Z sources like thermocouples, strain gauges, or capacitive sensors |
| ESD protection | 2000 V HBM rating - reduces risk of damage during handling and board-level testing |

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 total), rail-to-rail I/O, 2.5–6 V supply only | Better DC accuracy but incompatible with 12 V loop-powered systems; requires redesign for supply voltage and layout | Select when highest precision and rail-to-rail input are needed, and supply is limited to ≤6 V |
| LM324DR | Bipolar input (45 nA IB), higher VIO (7 mV max), no ESD protection, wider temp range (–40°C to 125°C) | Higher power (1.4 mW), unsuitable for high-Z sensors; better for cost-sensitive, non-battery applications with wide ambient range | Select for legacy industrial controls where low cost and extended temperature tolerance outweigh input bias and power concerns |
Compared with TLV2464IPW, TLC27L4CPW offers superior power efficiency and 12 V compatibility at the expense of input offset voltage; compared with LM324DR, it delivers 7-orders-of-magnitude lower input bias current and integrated ESD protection - critical for modern low-power, high-impedance sensor interfaces.

FAQ
What is the maximum operating temperature range for the TLC27L4CPW?
The TLC27L4CPW is characterized for operation from 0°C to 70°C (C-suffix grade). It supports supply voltages from 3 V to 16 V within this range. Operation outside this range is not guaranteed per datasheet specifications, and thermal derating must be applied if ambient exceeds 70°C. The TLC27L4IPW variant extends to –40°C to +85°C.
Does the TLC27L4CPW support true rail-to-rail input?
No - the TLC27L4CPW features rail-to-rail *output* and a common-mode input range extending 0.2 V below GND, but its input does not swing to VDD. At VDD = 5 V, the maximum common-mode input voltage is 3.5 V (0°C to 70°C), limiting high-side sensing without attenuation. This differs from true rail-to-rail input op amps like the TLV2464.
Can the TLC27L4CPW drive a 10 kΩ load at 5 V supply?
Yes - the TLC27L4CPW can source or sink ±30 mA per output, well exceeding the 0.5 mA required for a 10 kΩ load at 5 V. Output voltage swing remains within specification (VOH ≥ 3.2 V, VOL ≤ 50 mV at 25°C), ensuring full logic-level compatibility with downstream comparators or ADC drivers.
Is the TLC27L4CPW pin-compatible with other TSSOP-14 quad op amps?
No - while the TLC27L4CPW shares the standard TSSOP-14 footprint, its pinout (e.g., VDD on Pin 4, GND on Pin 11) differs from industry-standard configurations like the LM324 or TLV2464. Direct replacement requires PCB layout revision; verify pin mapping against Table 4-1 in the SLOS053E datasheet before substitution.
What is the typical input offset voltage drift over time for the TLC27L4CPW?
The TLC27L4CPW exhibits typical input offset voltage drift of 0.1 µV/month, including the first 30 days - a key stability metric for long-life field instruments. This value is measured under controlled conditions and reflects aging behavior of the LinCMOS™ process, not temperature-induced drift (which is specified separately as 1.1 µV/°C).
