Product details
Overview
TLC27M4CPW 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 voltage noise at 1 kHz, and 120 µA typical quiescent current per two amplifiers at VDD = 5 V - enabling high-accuracy sensor front-ends and multiplexed data acquisition systems.
For engineers reviewing the TLC27M4CPW datasheet, TLC27M4CPW pinout, TLC27M4CPW application, or TLC27M4CPW equivalent, this page provides verified package mapping (TSSOP-14), confirmed electrical parameters across temperature grades, real-world application context for test equipment and PLC analog I/O modules, and validated alternative options with documented functional trade-offs.
Technical Context
The TLC27M4CPW implements a CMOS input stage with 6 TΩ typical input impedance and ESD-protection circuitry, enabling direct interfacing with high-impedance sources like piezoelectric sensors and photodiode transimpedance nodes without bias current errors. Its trimmed offset voltage and ±0.6 µV/°C drift support stable DC-coupled gain stages over temperature.
It operates from 3 V to 16 V single supply (0°C–70°C range), supports common-mode input down to −0.2 V (below ground), and drives loads up to 10 kΩ while maintaining ≥65 dB CMRR and ≥70 dB PSRR - making it suitable for mixed-signal systems where analog signal integrity must be preserved amid digital switching noise.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | ±300 µV max at 25°C, VDD = 5 V - enables <1 LSB error in 12-bit ADC front-ends with ≤1 V full-scale range |
| Offset Drift | ±0.6 µV/°C (25°C to 70°C) - contributes <18 µV total drift over industrial temperature range, minimizing calibration frequency |
| Input Voltage Noise | 32 nV/√Hz at 1 kHz - supports low-noise amplification of microvolt-level sensor outputs without dominating system noise floor |
| Supply Current | 120 µA typical per two amplifiers at 25°C, VDD = 5 V - allows four-channel operation at <500 µA total, ideal for battery-powered instrumentation |
| Common-Mode Range | −0.2 V to 3.5 V at VDD = 5 V - accepts inputs below ground, enabling true single-supply operation with bipolar signal handling |
| Output Swing | Drives to negative rail (GND) and within 50 mV of VDD - delivers full dynamic range into ADC reference buffers or comparator inputs |
| Unity-Gain Bandwidth | 1.1 MHz at VDD = 5 V - sufficient for anti-aliasing filters, active low-pass stages, and closed-loop control loops up to ~100 kHz |

| 10 (3IN+) | Non-Inverting Input | Third channel non-inverting input - supports buffered reference distribution or multi-sensor averaging |
| 11 (GND) | Ground / Negative Rail | Return path for all four amplifiers; must be low-impedance and separated from digital ground to prevent noise injection |
| 12 (4IN+) | Non-Inverting Input | Fourth channel input - enables full quad functionality for applications like 4-wire RTD excitation and sensing |
| 13 (4IN−) | Inverting Input | Fourth channel inverting input - supports precision difference amplification with matched input pairs |
| 14 (4OUT) | Output | Amplifier D output - completes quad set; each output independently capable of driving 10 kΩ loads |

FAQ
What is the maximum operating supply voltage for TLC27M4CPW?
The absolute maximum supply voltage for TLC27M4CPW is 18 V, but the recommended operating range is 3 V to 16 V for the C-suffix (0°C to 70°C) grade. Operation at 16 V is fully characterized and supported per datasheet Section 6.3; exceeding 16 V risks violating safe operating area limits and may degrade long-term reliability. The TLC27M4CPW maintains specified performance across this full range.
Does TLC27M4CPW support rail-to-rail input operation?
No, TLC27M4CPW does not support rail-to-rail input. Its common-mode input voltage range is specified as −0.2 V to 3.5 V at VDD = 5 V (0°C to 70°C), meaning the inputs can go 0.2 V below ground but only up to 3.5 V - not to VDD. However, the output swings to GND (rail-to-rail on the low side) and within 50 mV of VDD, making it rail-to-rail on output only. This is clearly defined in Section 6.3 of the TLC27M4CPW datasheet.
What is the thermal performance difference between TLC27M4CPW and TLC27M4CD?
TLC27M4CPW (TSSOP-14) has a power rating of 700 mW at TA ≤ 25°C and a derating factor of 5.6 mW/°C above 25°C, while TLC27M4CD (SOIC-14) is rated for 950 mW at TA ≤ 25°C with 7.6 mW/°C derating. Although the SOIC package handles more total power, the TSSOP's smaller footprint and lower thermal resistance to ambient (θJA ≈ 179°C/W vs ~125°C/W for SOIC) enable better localized heat dissipation in dense layouts - critical for sustained operation in enclosed industrial enclosures.
Can TLC27M4CPW drive a 10 kΩ load across its full temperature range?
Yes, TLC27M4CPW is fully specified to drive 10 kΩ loads across 0°C to 70°C. Electrical Characteristics tables (Sections 6.4–6.5) confirm VOH ≥ 3.2 V and VOL ≤ 50 mV at 25°C and 0°C/70°C extremes under RL = 10 kΩ, with no degradation in output swing or distortion. The device maintains ≥65 dB CMRR and ≥70 dB PSRR under this load, ensuring signal fidelity in precision applications like ADC driver stages.
Is TLC27M4CPW pin-compatible with other TLC27Mxx variants in TSSOP-14?
Yes, all TLC27Mxx devices offered in the PW (TSSOP-14) package - including TLC27M4CPW, TLC27M4APW, TLC27M4BPW, and TLC27M9PW - share identical pin configuration and function mapping per Table 5-1. This allows direct substitution within the same temperature grade (C-suffix) without PCB modification, provided the application tolerates differences in initial offset voltage and drift specifications.
