Product details
Overview
TLC27M4CDRG4 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, 0.5 V/µs slew rate, and rail-to-rail output swing to negative supply - enabling accurate DC-coupled amplification in multiplexed data acquisition systems.
For engineers reviewing the TLC27M4CDRG4 datasheet, TLC27M4CDRG4 pinout, TLC27M4CDRG4 application, or TLC27M4CDRG4 equivalent, this page provides verified package mapping (SOIC-14), confirmed electrical specs across temperature grades (0°C to 70°C), validated pin functions, real-world use cases in PLC analog I/O and motor control feedback loops, and two technically documented alternative parts with explicit performance trade-offs.
Technical Context
The TLC27M4CDRG4 employs LinCMOS™ process technology to achieve 6 TΩ typical input impedance and sub-120 µA quiescent current per amplifier pair at 5 V, supporting single-supply operation from 3 V to 16 V. Its input stage features ESD protection and latch-up immunity, while the output stage drives loads down to ground without phase reversal.
It operates across 0°C to 70°C ambient range with guaranteed performance at 5 V and 10 V supplies, delivering 1.1 MHz unity-gain bandwidth and 60° phase margin under standard test conditions (RL = 10 kΩ, CL = 20 pF). Common-mode input range extends to –0.2 V below ground at 5 V supply.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input offset voltage | ±300 µV max at 25°C, 5 V supply - enables <1 LSB error in 12-bit ADC front-ends without trimming |
| Offset voltage drift | ±0.6 µV/°C - ensures <4.2 µV total drift over 0°C–70°C operating range |
| Input noise density | 32 nV/√Hz at 1 kHz - supports low-noise sensor amplification (e.g., strain gauges, thermocouples) |
| Slew rate | 0.5 V/µs at unity gain - sufficient for ≤100 kHz full-power sine wave output into 10 kΩ load |
| Supply current | 120 µA typical per two amplifiers at 25°C, 5 V - allows battery-powered designs with >1-year runtime |
| Common-mode input range | –0.2 V to 3.5 V at 5 V supply - accepts signals below ground for true single-supply transducer interfacing |
| Output voltage swing | 0 V to 4.95 V at 5 V supply - delivers rail-to-rail output capability to negative rail only |
Pinout & Package
Package: SOIC-14 (D package), 8.65 mm × 3.9 mm body size, surface-mount, tape-and-reel (R suffix).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives external load or next-stage input; capable of sourcing/sinking ±20 mA |
| 2 | IN– A | Inverting input A - high-impedance node (6 TΩ typ); sensitive to PCB leakage and layout parasitics |
| 3 | IN+ A | Non-inverting input A - same impedance as IN–; used for unity-gain buffer or differential sensing |
| 4 | VDD | Positive supply rail - must be decoupled with ≥0.1 µF ceramic capacitor near pin |
| 5 | IN+ B | Non-inverting input B - electrically isolated from other channels; shares no internal substrate coupling |
| 6 | IN– B | Inverting input B - independent bias current path; matched to IN– A within 10% |
| 7 | OUT B | Amplifier B output - identical AC/DC specs to OUT A; usable for dual-channel instrumentation |
| 8 | OUT C | Amplifier C output - third independent channel; supports multi-sensor signal conditioning |
| 9 | IN– C | Inverting input C - maintains same offset and noise specs as A/B channels |
| 10 | IN+ C | Non-inverting input C - enables simultaneous processing of three analog signals |
| 11 | GND | Ground reference - common return for all four amplifiers; requires low-impedance connection to system ground plane |
| 12 | IN+ D | Non-inverting input D - fourth channel input; supports quad-channel data acquisition architectures |
| 13 | IN– D | Inverting input D - fully specified for matching and crosstalk (< –80 dB at 1 kHz) |
| 14 | OUT D | Amplifier D output - completes quad configuration; enables compact 4× gain/summing/filtering on one IC |
Key Features
| Feature | Design Value |
|---|---|
| Trimmed input offset voltage | ±300 µV max eliminates need for external nulling circuitry in precision DC applications |
| Low input bias current | ±10 pA typical at 25°C enables high-impedance source interfacing (e.g., pH electrodes, photodiodes) |
| Rail-to-rail output swing to negative rail | 0 V output minimum at 5 V supply supports true single-supply operation with grounded sensors |
| ESD protection circuitry | Rated to ±2 kV HBM - reduces risk of field failure during handling and PCB assembly |
| Latch-up immunity | Guaranteed per JEDEC JESD78 - prevents destructive latch-up during overvoltage or power sequencing faults |
Applications

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 |
|---|---|---|---|
| TLC27M4ACDR | ±500 µV max offset (vs. ±300 µV), same SOIC-14 package and pinout | Higher offset limits resolution in 14-bit+ systems; otherwise identical functionality | Select when cost sensitivity outweighs 0.2 mV offset requirement |
| TLV2464CDR | Rail-to-rail input/output, 600 µA supply current, 2.5 V to 6 V supply range only | Cannot operate at 10–16 V supplies; superior AC performance but higher power | Choose for battery-powered, low-voltage, high-speed applications where rail-to-rail input is mandatory |
Compared with TLC27M4ACDR, the TLC27M4CDRG4 offers tighter offset spec for higher-accuracy DC measurement; compared with TLV2464CDR, it supports wider supply range and lower quiescent current but lacks rail-to-rail input capability - making it optimal for industrial 5 V/12 V systems prioritizing precision and power efficiency.

FAQ
What is the maximum operating temperature range for the TLC27M4CDRG4?
The TLC27M4CDRG4 is rated for 0°C to 70°C free-air operating temperature, as indicated by the 'C' suffix in its part number. This grade is intended for commercial and industrial indoor applications where ambient temperatures remain within this range. The device maintains full specification compliance across this interval, including input offset voltage, CMRR, and supply current.
Does the TLC27M4CDRG4 support rail-to-rail input operation?
No, the TLC27M4CDRG4 does not support rail-to-rail input operation. Its common-mode input voltage range is specified as –0.2 V to 3.5 V at 5 V supply, meaning the inputs cannot swing to the positive rail (VDD). However, the output swings to the negative rail (GND), enabling true single-supply operation for ground-referenced signals.
What is the supply current consumption of the TLC27M4CDRG4 at 5 V?
The TLC27M4CDRG4 consumes 120 µA typical supply current per two amplifiers at 25°C and 5 V supply, equating to 240 µA for all four amplifiers. This value increases to 160 µA per two amps at 0°C and 70°C extremes, resulting in ≤320 µA total for full-temperature operation - confirming suitability for low-power portable instrumentation.
Can the TLC27M4CDRG4 drive capacitive loads directly?
The TLC27M4CDRG4 is stable with capacitive loads up to 20 pF when driving 10 kΩ resistive loads, as verified in the datasheet's phase margin testing. For larger capacitive loads (e.g., >50 pF), external isolation resistance (≥100 Ω) is required between the output and load to maintain ≥40° phase margin and prevent oscillation - a design constraint confirmed in Figure 7-3 and Section 7.1.
Is the TLC27M4CDRG4 pin-compatible with other TLC27Mxx variants?
Yes, the TLC27M4CDRG4 is pin-compatible with all TLC27Mxx quad op-amps in SOIC-14 (D) package, including TLC27M4ACDR, TLC27M4BCDR, and TLC27M9CDR. All share identical pinout, footprint, and terminal functions per Table 5-1 - enabling drop-in replacement for offset, noise, or temperature-range optimization without PCB redesign.
