Product details
Overview
TLC27M2IPWRG4 from Texas Instruments is a dual precision operational amplifier using LinCMOS technology, designed for single-supply operation across −40°C to 85°C. It delivers 10 mV max input offset voltage at 25°C, 32 nV/√Hz input noise at 1 kHz, and 0.43 V/µs slew rate at VDD = 5 V - enabling accurate signal conditioning in battery-powered sensor interfaces and portable instrumentation.
For engineers reviewing the TLC27M2IPWRG4 datasheet, TLC27M2IPWRG4 pinout, TLC27M2IPWRG4 application, or TLC27M2IPWRG4 equivalent, this page provides verified package mapping (TSSOP-8), confirmed electrical parameters per TI SLOS051E Rev. August 2008, thermal performance data across industrial temperature range, and validated alternative options for precision analog front-end design.
Technical Context
The TLC27M2IPWRG4 implements silicon-gate LinCMOS process technology to achieve high input impedance (10¹² Ω typ), ultra-low input bias current (0.6 pA typ at 25°C), and latch-up immunity. Its input stage extends common-mode voltage range to the negative rail, supporting true single-supply operation down to 4 V.
It features internal ESD protection rated to 2000 V (MIL-STD-883C, Method 3015.2), rail-to-rail output swing capability, and stable unity-gain operation with 40° phase margin at 525 kHz bandwidth (VDD = 5 V). The device avoids bipolar power penalties while matching speed performance of general-purpose op-amps.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLC27M2CPW | Same silicon, C-suffix (0°C to 70°C) instead of I-suffix; otherwise identical pinout, specs, and TSSOP-8 package | Limited to commercial temperature range; unsuitable for extended ambient or industrial deployments | Select when operating environment stays within 0°C–70°C and cost sensitivity outweighs temperature margin |
| TLV2462IDR | Lower VIO (2 mV max), higher supply current (550 µA), rail-to-rail I/O, but narrower supply range (2.7–6 V) | Requires tighter supply regulation; better for low-voltage portable designs but incompatible with 12 V systems | Choose for enhanced DC accuracy in 3.3 V systems where power budget allows 2.6× higher IDD |
Compared with TLC27M2IPWRG4, TLC27M2CPW trades temperature robustness for lower cost in benign environments, while TLV2462IDR improves offset and I/O swing at the expense of supply flexibility and quiescent power - making TLC27M2IPWRG4 optimal for wide-supply, industrial-grade dual-amplifier functions.

FAQ
What is the maximum input offset voltage specification for TLC27M2IPWRG4 over its full operating temperature range?
The TLC27M2IPWRG4 has a maximum input offset voltage of 13 mV across the full −40°C to +85°C range, as specified in the "electrical characteristics" table for TLC27M2I at VDD = 5 V. At 25°C only, the limit is tighter: 10 mV max. This parameter directly impacts DC accuracy in precision amplification stages and must be considered alongside drift over temperature.
Does TLC27M2IPWRG4 support true single-supply operation with inputs referenced to ground?
Yes, the TLC27M2IPWRG4 supports true single-supply operation with inputs extending to the negative rail (GND). Its common-mode input voltage range is specified as −0.2 V to 3.5 V at VDD = 5 V across the full −40°C to +85°C range. This allows direct connection of grounded sensors such as thermocouples or shunt-based current monitors without level-shifting circuitry.
What is the recommended bypass capacitance and placement for TLC27M2IPWRG4?
A 0.1 µF ceramic capacitor is recommended directly between VDD (Pin 5) and GND (Pin 4), placed as close as possible to the device pins - ideally within 2 mm trace length. This minimizes high-frequency supply impedance and prevents instability or noise coupling, especially critical given the device's 525 kHz unity-gain bandwidth and 32 nV/√Hz noise floor.
Can TLC27M2IPWRG4 drive capacitive loads without oscillation?
The TLC27M2IPWRG4 is characterized for stability with up to 20 pF capacitive load in unity-gain configuration, achieving 40° phase margin at 25°C. Driving larger capacitive loads (e.g., >50 pF) may cause peaking or oscillation; TI recommends adding a series resistor (10–100 Ω) between the output and load capacitance to isolate the pole and maintain stability.
Is the TLC27M2IPWRG4 RoHS compliant and lead-free?
Yes, the TLC27M2IPWRG4 is RoHS compliant and lead-free. The "G4" suffix in the part number explicitly denotes TI's green packaging standard: lead-free terminations, halogen-free molding compound, and compliance with JEDEC J-STD-020 moisture sensitivity level 3 (MSL-3) for surface-mount assembly.
