Product details
Overview
TLC27M4IDRG4 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 TLC27M4IDRG4 datasheet, TLC27M4IDRG4 pinout, TLC27M4IDRG4 application, or TLC27M4IDRG4 equivalent, this device is selected for multiplexed data-acquisition front-ends, programmable logic controller analog I/O modules, motor control feedback amplification, and low-noise sensor signal conditioning where precision, low quiescent current (120 µA typ), and ESD-protected CMOS inputs are critical.
Technical Context
The TLC27M4IDRG4 implements a trimmed LinCMOS input stage delivering 6 TΩ typical input impedance and sub-nA bias currents, enabling direct interfacing with high-impedance sources like piezoelectric sensors and photodiode transimpedance nodes without loading error. 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 its 1.1 MHz unity-gain bandwidth and 0.5 V/µs slew rate support moderate-speed closed-loop configurations such as active filters, level shifters, and precision comparators with hysteresis - all while consuming less than 500 µA total supply current across four channels at 5 V.
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 without trimming |
| Offset voltage drift | ±0.6 µV/°C - ensures <2.5 µV total drift over 0–70°C ambient, critical for stable calibration |
| Input noise density | 32 nV/√Hz at 1 kHz - supports low-noise amplification of microvolt-level sensor signals |
| Supply current (4 op-amps) | 120 µA typical at 25°C, VDD = 5 V - allows battery-powered or energy-constrained designs |
| Common-mode input range | –0.2 V to VDD – 1.5 V at 5 V - permits true single-supply operation with ground-referenced inputs |
| Output voltage swing | Includes negative rail (GND) - eliminates need for dual supplies in level-shifting and reference buffering |
| Unity-gain bandwidth | 1.1 MHz - sufficient for anti-aliasing filters, active gain stages, and closed-loop control up to ~100 kHz |

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 |
|---|---|---|---|
| TLV274IPW | Lower supply current (65 µA/ch), but higher offset (2 mV max) and reduced CMRR (70 dB) | Better suited for ultra-low-power battery applications where absolute precision is secondary to current draw | Select when system-level power budget is tighter than DC accuracy requirements |
| OPA4188AIDR | Zero-drift architecture, 0.003 µV/°C drift, but higher cost and 175 µA/ch supply current | Required for <0.1 µV/°C drift in metrology-grade instruments or long-duration unattended logging | Select only when thermal drift must be eliminated - not for general-purpose precision use |
Compared with TLV274IPW and OPA4188AIDR, the TLC27M4IDRG4 offers the optimal balance of low offset (±300 µV), ultra-low drift (±0.6 µV/°C), and sub-150 µA total quiescent current - making it ideal for industrial analog I/O where cost, accuracy, and reliability must coexist without zero-drift complexity or excessive power penalty.

FAQ
What is the maximum operating temperature range for the TLC27M4IDRG4?
The TLC27M4IDRG4 is rated for operation from –40°C to +85°C, with electrical specifications fully guaranteed across this industrial temperature range. Absolute maximum ratings extend to –55°C to +125°C, but parametric performance is only specified within the –40°C to +85°C range per the official TI datasheet revision SLOS093E.
Does the TLC27M4IDRG4 support true single-supply operation with inputs referenced to ground?
Yes, the TLC27M4IDRG4 supports true single-supply operation: its common-mode input voltage range extends to –0.2 V (i.e., 200 mV below ground) at VDD = 5 V, and its output swings fully to the negative rail (GND). This enables ground-referenced sensor interfaces and rail-to-rail signal handling without dual supplies.
How many operational amplifiers are integrated into the TLC27M4IDRG4?
The TLC27M4IDRG4 integrates four independent, precision operational amplifiers in a single SOIC-14 package. All four channels share identical electrical specifications including offset voltage, drift, noise, and bandwidth - enabling matched multi-channel signal conditioning without inter-channel calibration.
What is the typical supply current consumption of the TLC27M4IDRG4 at 5 V?
The TLC27M4IDRG4 draws 120 µA typical supply current per two amplifiers at 25°C and VDD = 5 V, resulting in approximately 240 µA total for all four op-amps. This ultra-low quiescent current makes the TLC27M4IDRG4 well-suited for energy-sensitive industrial and portable instrumentation designs.
Is the TLC27M4IDRG4 pin-compatible with other devices in the TLC27Mxx family?
Yes, the TLC27M4IDRG4 is pin-compatible with all SOIC-14 variants in the TLC27Mxx family (e.g., TLC27M4CDR, TLC27M4AIDR, TLC27M4BIDR), sharing identical pinout, footprint, and terminal functions. This allows drop-in replacement across offset grade variants without PCB layout changes.
