Product details
Overview
TLC2201AMDG4 from Texas Instruments is a precision, low-noise single-channel operational amplifier using Advanced LinCMOS™ process. It delivers 30 nV/√Hz max input noise at 10 Hz, 500 µV max input offset voltage, rail-to-rail output swing, and operates across −55°C to 125°C. It serves as a high-impedance signal conditioner in military-grade sensor front-ends and precision data acquisition systems.
For engineers reviewing the TLC2201AMDG4 datasheet, TLC2201AMDG4 pinout, TLC2201AMDG4 application, or TLC2201AMDG4 equivalent, this page provides verified specifications, military-temperature validated performance, package-specific terminal mapping, and direct alternatives for low-noise analog signal chains requiring dc precision and ESD-hardened operation.
Technical Context
The TLC2201AMDG4 implements a dual-differential input stage with silicon-gate LinCMOS™ architecture, enabling input offset voltage stability over temperature (0.5 µV/°C typ) and time far exceeding metal-gate JFET amplifiers. Its common-mode input range includes the negative rail, supporting true single-supply operation down to VDD− = 0 V when configured with ground-referenced negative supply.
It features internal ESD protection rated to 2000 V (MIL-PRF-38535 Method 3015.2), −100-mA surge current tolerance on inputs/outputs without latch-up, and is fully specified for both split-supply (±2.3 V to ±8 V) and single-supply (4.6 V to 16 V) configurations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Noise Voltage | 30 nV/√Hz max at 10 Hz - enables resolution of sub-µV signals in low-frequency instrumentation |
| Input Offset Voltage | 500 µV max - supports accurate dc-coupled amplification without trimming in rugged environments |
| Supply Voltage Range | ±2.3 V to ±8 V (split) or 4.6 V to 16 V (single) - accommodates wide industrial/military power rails |
| Operating Temperature | −55°C to +125°C - qualified for full military temperature range per M-suffix designation |
| Rail-to-Rail Output | Swing within 200 mV of rails (at 10 kΩ load) - maximizes dynamic range in low-voltage systems |
| Input Bias Current | 1 pA typ at 25°C - preserves signal integrity in high-impedance pH sensors and piezoelectric transducers |
| Common-Mode Input Range | Includes VDD− (negative rail) - allows direct interfacing to ground-referenced sensors in single-supply designs |
Pinout & Package
TLC2201AMDG4 is supplied in an 8-pin SOIC (D) package with gull-wing leads, moisture sensitivity level 1, and RoHS-compliant finish. The device uses standard D-package pin numbering and thermal profile compatibility with JEDEC J-STD-020.

| 3 | Output (OUT) | Rail-to-rail output capable of sourcing/sinking ±50 mA; stable into 10 kΩ loads |
| 4 | VDD− / Ground | Negative supply or ground reference; common-mode range extends to this pin |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision low-noise op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA211IDR | Lower noise (1.1 nV/√Hz), but only rated to 105°C; requires external VOS trim for <50 µV offset | Not qualified for −55°C operation; unsuitable for extended cold-start military platforms | Select when ultra-low noise dominates over temperature range and board space permits trim components |
| AD8628ARZ | Zero-drift architecture; 0.5 µV max VIO, but higher 1/f noise (150 nV/√Hz at 0.1 Hz) and 125°C max TJ | Superior dc accuracy but inferior low-frequency SNR in vibration-prone sensor nodes | Select for dc-stable integrators or zero-error summing junctions where 1/f noise is filtered out |
Compared with OPA211IDR and AD8628ARZ, the TLC2201AMDG4 uniquely balances military-temperature operation, B-grade low-noise certification, and LinCMOS™ dc stability-making it optimal for unattended, wide-temperature analog signal chains where reliability trumps ultimate noise floor.

FAQ
What is the maximum supply voltage for TLC2201AMDG4?
The TLC2201AMDG4 has an absolute maximum supply voltage of ±8 V for split-supply operation or 16 V for single-supply use. Operation beyond these limits risks permanent damage. Recommended operating range is ±2.3 V to ±8 V (split) or 4.6 V to 16 V (single), with full electrical specifications guaranteed across that span for the TLC2201AMDG4.
Does TLC2201AMDG4 support true single-supply operation with input referenced to ground?
Yes. The TLC2201AMDG4's common-mode input voltage range includes the negative rail (VDD−), allowing the IN+ and IN− pins to accept signals down to ground potential when VDD− is tied to 0 V. This enables direct interfacing with ground-referenced sensors without level-shifting circuitry - a key capability confirmed for the TLC2201AMDG4 in its datasheet.
What is the meaning of the 'M' and 'G4' suffixes in TLC2201AMDG4?
The 'M' suffix denotes full military temperature range qualification (−55°C to +125°C), while 'G4' indicates TI's green packaging standard: lead-free, RoHS-compliant, and halogen-free construction. Together, TLC2201AMDG4 specifies a military-grade, environmentally compliant SOIC-8 op-amp - distinct from commercial (C) or industrial (I) variants.
Can TLC2201AMDG4 drive capacitive loads without instability?
The TLC2201AMDG4 is unity-gain stable into 100 pF loads with 10 kΩ series resistance, as verified by phase margin ≥48° at unity gain. Driving larger capacitive loads directly may cause peaking or oscillation; for >100 pF, a small isolation resistor (e.g., 20–50 Ω) in series with the output is recommended to maintain stability in the TLC2201AMDG4.
How does the noise performance of TLC2201AMDG4 compare to TLC2201CD?
The TLC2201AMDG4 is B-grade qualified with tighter noise limits: ≤30 nV/√Hz at 10 Hz and ≤12 nV/√Hz at 1 kHz. In contrast, the TLC2201CD (C-grade) is specified at ≤35 nV/√Hz and ≤15 nV/√Hz respectively. This B-grade screening makes the TLC2201AMDG4 preferred for low-frequency precision applications where noise floor directly impacts measurement resolution.
