Texas Instruments TLC27M4CPWR

Overview

TLC27M4CPWR from Texas Instruments is a LinCMOS™ precision quad operational amplifier optimized for low-power, rail-to-rail output (negative rail inclusive), high-input-impedance signal conditioning in 0°C to 70°C industrial environments. It delivers ±300 µV max input offset voltage at 25°C, 32 nV/√Hz input noise at 1 kHz, and 120 µA typical quiescent current per amplifier pair at VDD = 5 V - enabling high-accuracy sensor interfacing and multiplexed data acquisition.

For engineers reviewing the TLC27M4CPWR datasheet, TLC27M4CPWR pinout, TLC27M4CPWR application, or TLC27M4CPWR equivalent, this page provides verified package mapping (TSSOP-14), confirmed electrical specifications across temperature grades, real-world application context for test equipment and PLC analog I/O, and validated alternative options with documented functional trade-offs.

Technical Context

The TLC27M4CPWR implements a CMOS input stage with 6 TΩ typical input impedance and ESD-protection circuitry, supporting single-supply operation from 3 V to 16 V. Its trimmed offset voltage and ±0.6 µV/°C drift enable stable DC-coupled gain stages without frequent recalibration.

It features four independent amplifiers sharing one 14-pin TSSOP package, each with rail-inclusive output swing, unity-gain bandwidth of 1.1 MHz (at 5 V), and phase margin of 60° - making it suitable for closed-loop control feedback paths and anti-aliasing filtering where stability under capacitive loads matters.

FAQ

What is the maximum operating temperature range for the TLC27M4CPWR?

The TLC27M4CPWR is rated for 0°C to 70°C operation, as indicated by its "C" suffix. This grade supports commercial and industrial environments where ambient temperatures remain within that band. It is not qualified for extended ranges like −40°C to 85°C (I-suffix) or −55°C to 125°C (M-suffix), and using it outside 0°C–70°C may result in degraded offset drift or increased supply current beyond specification.

Does the TLC27M4CPWR support rail-to-rail input operation?

No, the TLC27M4CPWR does not support rail-to-rail input. Its common-mode input voltage range extends to −0.2 V (below GND) and up to VDD − 1.5 V at 5 V supply - meaning it accepts inputs down to the negative rail but not up to VDD. For true rail-to-rail input capability, consider alternatives like the TLV2464IPW, which explicitly specifies RRI/O architecture.

Can the TLC27M4CPWR drive a 10 kΩ load while maintaining specified AC performance?

Yes, the TLC27M4CPWR is characterized with RL = 10 kΩ in its Electrical Characteristics tables (e.g., slew rate, unity-gain bandwidth, and output voltage swing). At 25°C and VDD = 5 V, it delivers 1.1 MHz unity-gain bandwidth and 0.5 V/µs slew rate into 10 kΩ, ensuring stable operation in standard gain-of-10 or unity-gain buffer configurations without external compensation.

How does the input bias current of the TLC27M4CPWR affect high-impedance sensor interfacing?

The TLC27M4CPWR has ±10 pA typical input bias current at 25°C, rising to ±60 pA at 70°C. When interfacing with sensors having >1 MΩ source impedance (e.g., pH electrodes or piezoelectric elements), this bias current introduces <60 µV of offset error across a 1 MΩ resistor - well within the ±300 µV max input offset budget. Its 6 TΩ input impedance further minimizes loading-induced signal attenuation.

Is the TLC27M4CPWR pin-compatible with other members of the TLC27Mxx family?

Yes, all TLC27Mxx quad op-amps - including TLC27M4CPWR, TLC27M4CDR, TLC27M4ACD, and TLC27M9CD - share identical 14-pin TSSOP (PW) or SOIC (D) pinouts and terminal functions. The only differences lie in internal trimming (offset grade), temperature range, and packaging - allowing direct substitution in the same footprint when electrical specs align with system requirements.
