Product details
Overview
TLC27L9CN from Texas Instruments is a precision quad operational amplifier using LinCMOS™ technology, delivering 1 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 operates from 4 V to 16 V over –40°C to +85°C and supports single-supply sensor signal conditioning in battery-powered field transmitters.
For engineers reviewing the TLC27L9CN datasheet, TLC27L9CN pinout, TLC27L9CN application, or TLC27L9CN equivalent, this page provides verified specifications, validated pin functions, confirmed operating conditions for industrial temperature range, and real-world design context for low-power analog front-ends.
Technical Context
The TLC27L9CN implements silicon-gate LinCMOS™ process architecture, enabling high input impedance (10¹² Ω typical) and sub-picoampere input bias current (0.6 pA typ at 25°C). Its input stage supports common-mode voltage extension below the negative rail, and its output stage delivers rail-to-rail swing with low-level output voltage as low as 1 mV (at 25°C, VDD = 5 V).
Designed for single-supply operation, the device maintains stable gain (AVD ≥ 50 V/mV) and phase margin (≥34° at 25°C) across its full operating temperature range. Its low 1 µV/°C input offset drift and ESD protection (2000 V per MIL-STD-883C) support long-term reliability in harsh industrial environments.
Key Specifications

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 |
|---|---|---|---|
| TLV27L4CN | Lower max VIO (2 mV), same LinCMOS process, identical PDIP-14 package | Targeted at cost-sensitive designs where ±2 mV offset is acceptable | Select TLV27L4CN if 12-bit system accuracy suffices and BOM cost reduction is prioritized |
| OPA2333PA | Zero-drift architecture, 12 µV max VIO, higher supply current (17 µA per amp), SOIC-8 dual | Requires two devices and layout changes; suited for sub-µV DC stability needs | Choose OPA2333PA only when microvolt-level drift performance justifies added complexity and cost |
Compared with TLC27L9CN, TLV27L4CN offers lower cost but relaxed offset spec, while OPA2333PA delivers superior DC precision at significantly higher power and packaging overhead-making TLC27L9CN optimal for balanced precision, power, and form factor in industrial sensor nodes.

FAQ
What is the maximum input offset voltage specification for TLC27L9CN at 25°C?
The TLC27L9CN has a maximum input offset voltage of 1000 µV (1 mV) at 25°C, as specified in the Electrical Characteristics table for I-suffix devices under VDD = 5 V test conditions. This value is guaranteed across the full –40°C to +85°C operating range up to 2000 µV, making TLC27L9CN suitable for high-accuracy DC amplification without trimming.
Does TLC27L9CN support true single-supply operation with inputs extending below ground?
Yes, TLC27L9CN supports true single-supply operation with its common-mode input voltage range extending to –0.2 V relative to GND at 25°C. This allows direct interfacing of ground-referenced sensors (e.g., thermistors, bridge circuits) without level-shifting circuitry-confirmed in Section 5.3 Recommended Operating Conditions and Table 4-1 Pin Functions.
What is the typical supply current consumption of TLC27L9CN at 5 V and 25°C?
The typical supply current for TLC27L9CN is 39 µA per amplifier (156 µA total for all four), with a maximum of 68 µA total (17 µA per amp) at 25°C and VDD = 5 V. This ultra-low quiescent current enables multi-year operation on primary lithium batteries in remote field transmitters-verified in Section 5.8 Electrical Characteristics, I-suffix data.
Which package types are available for TLC27L9CN, and what is its pin count?
TLC27L9CN is offered exclusively in the N (PDIP-14) package: a 14-pin plastic dual in-line package with 0.3-inch body width. This is explicitly listed in the Device Information table under TLC27L9 row and confirmed in Figure 4-1 and Table 4-1 of the datasheet-no SOIC, SOP, or TSSOP variants exist for the CN suffix.
How does the input bias current of TLC27L9CN compare to bipolar op-amps, and why does it matter?
TLC27L9CN exhibits typical input bias current of 0.6 pA at 25°C-over six orders of magnitude lower than typical bipolar op-amps (e.g., LM324: ~45 nA). This ultra-low bias current prevents signal degradation when driving high-impedance sources like pH electrodes or piezoelectric sensors, preserving accuracy without guard rings or leakage compensation-confirmed in Sections 5.4 and 5.8.
