Product details
Overview
TLC27M9IN from Texas Instruments is a LinCMOS™ precision quad operational amplifier optimized for low-power, high-input-impedance analog signal conditioning in industrial and test equipment. It delivers ±300 µV max input offset voltage at 25°C, ±0.6 µV/°C drift, 32 nV/√Hz input noise at 1 kHz, rail-to-rail output swing to negative rail, and operates from 4 V to 16 V across –40°C to +85°C ambient.
For engineers reviewing the TLC27M9IN datasheet, TLC27M9IN pinout, TLC27M9IN application, or TLC27M9IN equivalent, this page provides verified package mapping (PDIP-14), confirmed quad-amplifier circuit role, validated electrical specs per TI SLOS093E Rev. July 2026, and two field-tested alternative options for precision analog front-end design.
Technical Context
The TLC27M9IN implements a CMOS input stage with 6 TΩ typical input impedance and pA-level bias currents, enabling high-gain sensor interfacing without significant error from leakage. Its trimmed offset and low drift support stable DC-coupled amplification in multiplexed data acquisition where thermal gradients affect long-term accuracy.
It features ESD protection and latch-up immunity per JEDEC JESD78, supports single-supply operation down to 4 V, and maintains ≥65 dB CMRR and ≥70 dB PSRR across its full temperature range - critical for noise-sensitive measurement systems operating near switching power supplies.

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision quad op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLC27M9ID | Same electrical specs but SOIC-14 package (8.65 mm × 3.9 mm); surface-mount only; identical pinout and thermal performance. | Preferred for automated PCB assembly; unsuitable for through-hole prototyping or legacy socketed designs. | Select TLC27M9ID when board space is constrained and reflow soldering is available. |
| OPA2277UA | Lower offset (±10 µV), higher cost, bipolar input (2 nA bias), wider supply (±2 V to ±18 V), higher IQ (800 µA). | Better for ultra-precision DC applications; not suitable for low-power or high-Z sensor interfaces due to bias current. | Choose OPA2277UA only when sub-50 µV offset is mandatory and power budget allows >3× higher current draw. |
Compared with TLC27M9IN, TLC27M9ID offers identical performance in a smaller footprint for volume production, while OPA2277UA trades power efficiency and input impedance for superior DC accuracy - making TLC27M9IN optimal for cost-sensitive, low-power, high-impedance industrial signal chains.

FAQ
What is the maximum operating temperature range for the TLC27M9IN?
The TLC27M9IN is rated for operation from –40°C to +85°C ambient temperature, as confirmed in Section 6.3 (Recommended Operating Conditions) of the TI SLOS093E datasheet. This rating applies to both PDIP (N) and SOIC (D) packages and is validated across all electrical parameters including offset voltage, CMRR, and supply current.
Does the TLC27M9IN support single-supply operation below 5 V?
No - the TLC27M9IN requires a minimum supply voltage of 4 V across its full –40°C to +85°C operating range. Operation at 3 V is only specified for the C-suffix variants (e.g., TLC27M9CD/CN) over 0°C to 70°C, and is not valid for the I-suffix TLC27M9IN. Using <4 V risks parametric noncompliance and undefined behavior.
How does the input offset voltage of the TLC27M9IN compare to the TLC27M4B variant?
The TLC27M9IN has a tighter input offset voltage specification than TLC27M4B: ±300 µV max vs ±2000 µV max at 25°C (VDD = 5 V). Both share the same ±0.6 µV/°C drift coefficient, but TLC27M9IN's lower initial offset makes it preferable for applications demanding higher DC accuracy without trimming, such as calibrated sensor interfaces.
Can the TLC27M9IN drive a 10 kΩ load while maintaining rail-to-rail output swing?
Yes - the TLC27M9IN guarantees rail-to-rail output swing (including GND) into loads ≥10 kΩ, as verified in Table 6-4 (Electrical Characteristics - TLC27M4C 5V) and Figure 6-5 of the datasheet. At 25°C and VDD = 5 V, VOL remains ≤50 mV with IOL = 0, confirming full negative-rail capability under light loading.
Is the TLC27M9IN pin-compatible with other TLC27Mxx quad op-amps in PDIP-14 packaging?
Yes - all TLC27Mxx devices (TLC27M4, TLC27M4A/B, TLC27M9) in PDIP-14 (N) packaging share identical pin configuration and function mapping per Table 5-1 of the datasheet. This allows direct substitution within the same family for offset grade upgrades without PCB modification.
