Product details
Overview
TLC27M4AIN 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 ±300µV max input offset voltage at 25°C, ±0.6µV/°C drift, 32nV/√Hz input noise at 1kHz, rail-to-rail output swing to negative supply, and operates from 4V to 16V across –40°C to 85°C.
For engineers reviewing the TLC27M4AIN datasheet, TLC27M4AIN pinout, TLC27M4AIN application, or TLC27M4AIN equivalent, this page provides verified package mapping (PDIP-14), confirmed electrical specs including input bias current (±10pA typ), common-mode range (–0.2V to 3.5V at 5V), supply current (120µA per two amps), and real-world use cases in PLC analog I/O and motor control feedback loops.
Technical Context
The TLC27M4AIN uses LinCMOS™ process technology to achieve ultra-low input bias current (±10pA typ) and high input impedance (6TΩ typ), enabling accurate sensing in high-impedance source applications such as thermocouple amplification and photodiode transimpedance stages. Its trimmed offset voltage and low drift support stable DC-coupled gain without frequent recalibration.
It features rail-to-rail output swing down to the negative rail, supporting single-supply operation in systems with limited headroom-e.g., 5V-powered data acquisition front-ends. The device maintains 65dB minimum CMRR and 70dB kSVR across its full operating temperature range, ensuring robust performance in 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 |
|---|---|---|---|
| TLV274IPW | Lower supply current (125µA per amp), wider temp range (–40°C to 125°C), but higher offset (1.1mV max) | Better suited for extended-temp embedded control; less ideal for sub-mV DC accuracy | Select when ultra-low power per channel and extended temperature operation outweigh offset sensitivity |
| OPA2277UA | Chopper-stabilized architecture, lower offset (10µV max), higher cost, SOIC-8 dual only (requires two ICs for quad) | Required where <50µV offset and <0.1µV/°C drift are mandatory, e.g., medical instrumentation | Select when absolute DC precision exceeds LinCMOS™ capability and dual-SOIC layout is acceptable |
Compared with TLV274IPW and OPA2277UA, the TLC27M4AIN offers the best balance of low offset (±300µV), ultra-low bias current (±10pA), and quad integration in PDIP-14 - making it optimal for industrial analog I/O where high-Z sources and moderate DC accuracy coexist.

FAQ
What is the maximum operating temperature range for the TLC27M4AIN?
The TLC27M4AIN is rated for operation from –40°C to +85°C. This industrial temperature grade is confirmed in Table 4-1 and Section 6.3 of the datasheet, where the "I" suffix denotes the –40°C to 85°C range. Absolute maximum junction temperature is 150°C, but continuous operation above 85°C is not supported per specifications.
Does the TLC27M4AIN support rail-to-rail input operation?
No, the TLC27M4AIN does not support rail-to-rail input. Its common-mode input voltage range is specified as –0.2V to 3.5V at VDD = 5V and –0.2V to 8.5V at VDD = 10V (Section 6.3). While the output swings to the negative rail, inputs must remain ≥0.2V above GND and ≤VDD – 1.5V to maintain specified performance.
What is the typical supply current for the TLC27M4AIN at 25°C?
The typical supply current for the TLC27M4AIN is 120µA per two amplifiers at 25°C and VDD = 5V, meaning ~240µA total for all four op-amps. This value is confirmed in Section 6.4 Electrical Characteristics under IQ (supply current) for the TLC27M4AI variant at 25°C.
Can the TLC27M4AIN be used with a single 3.3V supply?
No, the TLC27M4AIN cannot be operated from a 3.3V supply. Its minimum recommended supply voltage is 4V across the –40°C to 85°C range (Section 6.3). At 3.3V, key parameters-including input offset voltage, CMRR, and output swing-fall outside guaranteed specifications and may result in functional failure.
Is the TLC27M4AIN pin-compatible with other TLC27Mxx variants in PDIP-14?
Yes, the TLC27M4AIN is pin-compatible with all TLC27Mxx quad op-amps in the N (PDIP-14) package, including TLC27M4N, TLC27M4BN, and TLC27M9N. Pin configuration and functions are identical per Table 5-1, enabling drop-in replacement where electrical specs meet system requirements.
