Product details
Overview
TLC27M4IPWR 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.
For engineers reviewing the TLC27M4IPWR datasheet, TLC27M4IPWR pinout, TLC27M4IPWR application, or TLC27M4IPWR equivalent, this device is selected for precision sensor interfacing, multiplexed data acquisition, and low-quiescent-current analog front-ends where input bias current below 60 pA and CMOS input stage advantages are critical.
Technical Context
The TLC27M4IPWR implements a complementary metal-oxide-semiconductor (LinCMOS™) input stage enabling 6 TΩ typical input impedance and sub-60 pA input bias current at 25°C. Its architecture supports single-supply operation with common-mode input range extending to –0.2 V (below ground) and output swing to the negative rail.
It features internal ESD protection and latch-up immunity, and is characterized across three temperature grades - C (0°C–70°C), I (–40°C–85°C), and M (–55°C–125°C). The 'I' suffix in TLC27M4IPWR confirms its –40°C to 85°C operating range and TSSOP-14 packaging.

IC Role / Device Role / Timing Role: Quad amplifier provides simultaneous buffering, filtering, and level-shifting for four independent channels. Use Value: Low input bias current prevents error in high-impedance RTD bridge circuits; rail-to-rail output maximizes ADC dynamic range. | Use Scenario: High-channel-count DAQ systems switch between dozens of sensors using analog multiplexers, requiring low-drift, low-noise pre-amplification. IC Role / Device Role / Timing Role: Each TLC27M4IPWR channel conditions one sensor path prior to multiplexer input. Use Value: ±300 µV offset and ±0.6 µV/°C drift ensure measurement stability across temperature; 32 nV/√Hz noise preserves SNR for µV-level signals. |
| Test and Measurement Equipment | Motor Drive Control Modules |
Use Scenario: Benchtop multimeters and signal analyzers require precision DC amplification and offset correction in front-end signal paths. IC Role / Device Role / Timing Role: Used in auto-zeroing circuits and programmable gain stages for calibrated voltage/current measurement. Use Value: Trimmed offset voltage eliminates need for external trimming potentiometers; CMOS input avoids leakage-induced errors in nanoampere measurements. | Use Scenario: Inverter control boards monitor phase currents and bus voltage with isolation amplifiers and shunt-based sensing. IC Role / Device Role / Timing Role: Amplifies low-voltage shunt resistor signals and conditions feedback from isolated voltage sensors. Use Value: 4–16 V supply range aligns with auxiliary 5 V/12 V rails; –40°C to 85°C rating ensures reliability in motor control enclosures. |
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 |
|---|---|---|---|
| TLC27M4CDR | SOIC-14 package; C-temp grade (0°C–70°C); same electrical specs but lower temperature range | Suitable for commercial-grade instrumentation or non-extended-temperature industrial controls | Select when board space allows SOIC and ambient temperature stays within 0°C–70°C |
| TLC27M4IDR | SOIC-14 package; identical I-temp grade (–40°C–85°C) and electrical performance | Drop-in replacement where TSSOP footprint is not available or reflow compatibility is constrained | Choose for legacy SOIC layouts or when TSSOP assembly capability is limited |

FAQ
What is the maximum supply voltage for the TLC27M4IPWR?
The absolute maximum supply voltage for the TLC27M4IPWR is 18 V, but the recommended operating range is 4 V to 16 V across its full –40°C to 85°C temperature specification. Operation above 16 V risks exceeding dissipation limits and degrading long-term reliability, even if within absolute ratings.
Does the TLC27M4IPWR support rail-to-rail input operation?
No - the TLC27M4IPWR does not support rail-to-rail input. Its common-mode input voltage range extends to –0.2 V (below ground) and up to VDD – 1.5 V at 25°C, depending on supply voltage. However, it does provide rail-to-rail output swing to the negative rail (GND), making it suitable for single-supply configurations.
What is the input bias current specification for the TLC27M4IPWR at 85°C?
At 85°C, the TLC27M4IPWR exhibits a maximum input bias current of 600 pA, as specified in the TLC27M4I electrical characteristics table. This remains well below 1 nA, preserving accuracy in high-impedance sensor interfaces such as photodiode transimpedance amplifiers or strain gauge bridges.
Can the TLC27M4IPWR drive a 10 kΩ load across its full temperature range?
Yes - the TLC27M4IPWR is fully specified to drive 10 kΩ loads across –40°C to 85°C, with output voltage swing and slew rate validated under RL = 10 kΩ conditions in both 5 V and 10 V supply configurations. Its output stage maintains VOH ≥ 3 V and VOL ≤ 50 mV into 10 kΩ at 85°C.
Is the TLC27M4IPWR pin-compatible with other devices in the TLC27Mxx family?
Yes - all TLC27Mxx quad op-amps, including TLC27M4IPWR, TLC27M4IDR, and TLC27M4CDR, share identical pinouts in their respective packages (TSSOP-14 and SOIC-14). This allows direct substitution between temperature grades and package types without PCB redesign, provided mechanical and thermal constraints are met.
