Product details
Overview
TLC2201AMD 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 in high-impedance sensor signal conditioning and precision analog front-ends for military-grade instrumentation.
For engineers reviewing the TLC2201AMD datasheet, TLC2201AMD pinout, TLC2201AMD application, or TLC2201AMD equivalent, key selection criteria include its military-temperature-range operation, low 1-pA typical input bias current, common-mode input range extending to the negative rail, and compatibility with both single-supply (4.6 V to 16 V) and split-supply (±2.3 V to ±8 V) configurations.
Technical Context
The TLC2201AMD implements a dual-stage CMOS input stage with silicon-gate technology, enabling exceptional input offset voltage stability over temperature (0.5 µV/°C typ) and time. Its architecture supports fully specified operation under single-supply (e.g., 5 V) and split-supply (e.g., ±5 V) conditions, with common-mode input voltage range including the negative rail and rail-to-rail output capability.
It features internal ESD protection rated to 2000 V (MIL-PRF-38535, Method 3015.2), input surge current tolerance of ±100 mA, and absolute maximum supply ratings of ±8 V. The device is not unity-gain stable-phase margin is 45°–48° at unity gain with 10 kΩ load and 100 pF capacitive load.

Pinout & Package
TLC2201AMD is available in the 8-pin ceramic DIP (JG) package, with lead finish suitable for high-reliability soldering (300°C for 60 s). The package provides hermetic sealing and thermal stability required for extended military-temperature operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (IN−) | Differential input node; high-impedance CMOS gate input requiring guarded layout to preserve 1-pA bias current spec |
| 2 | Non-Inverting Input (IN+) | Differential input node; common-mode range extends to VDD−, enabling ground-sensing configurations |
| 3 | Output (OUT) | Class-AB output stage capable of ±50 mA short-circuit current; rail-to-rail swing within 50 mV of rails at light load |
| 4 | VDD− / Ground | Negative supply or ground reference; internally connected to substrate backside in JG package per bonding diagram |
| 5 | NC | No internal connection - must be left unconnected or tied to ground per layout best practices |
| 6 | VDD+ | Positive supply pin; accepts up to +8 V (split) or +16 V (single); decoupling capacitor required within 1 cm |
| 7 | NC | No internal connection - no routing or metallization recommended |
| 8 | NC | No internal connection - unused pad; avoid solder mask openings to prevent contamination |
Key Features
| Feature | Design Value |
|---|---|
| Advanced LinCMOS™ Process | Silicon-gate CMOS input stage delivering 0.5 µV/°C offset drift and superior long-term stability vs metal-gate alternatives |

Applications
| Strain Gauge Signal Conditioning | Thermopile-Based Temperature Sensing |
|---|---|
Use Scenario: Amplifying microvolt-level Wheatstone bridge outputs from metal foil strain gauges in structural health monitoring systems. IC Role / Device Role / Timing Role: Precision instrumentation amplifier front-end with ultra-low input bias current to prevent bridge imbalance errors. Use Value: 1-pA typical input bias current avoids loading high-resistance bridge arms; 500-µV max VIO limits zero-point error to <0.1% FS in 0.5-mV/V bridge configurations. | Use Scenario: Low-noise amplification of thermopile outputs (typically 10–100 µV/°C) in non-contact infrared thermometers. IC Role / Device Role / Timing Role: First-stage DC-coupled amplifier with sub-30-nV/√Hz noise density to resolve <0.1°C resolution at 1-Hz bandwidth. Use Value: 30 nV/√Hz max at 10 Hz directly sets minimum detectable signal; rail-to-rail output drives ADC reference without level-shifting. |
| Downhole Oilfield Instrumentation | Military-Grade Data Acquisition Front-End |
Use Scenario: Signal conditioning in high-temperature (>125°C ambient) pressure and flow sensors deployed in oil/gas wellbores. IC Role / Device Role / Timing Role: High-stability op-amp operating continuously at 125°C junction temperature with guaranteed parametric performance. Use Value: −55°C to +125°C operating range and 0.5 µV/°C VIO drift ensure calibration holdover over extended deployment cycles without recalibration. | Use Scenario: Analog front-end for 16-bit SAR ADCs in secure communications equipment requiring EMI-hardened analog stages. IC Role / Device Role / Timing Role: Low-noise, low-drift buffer and gain stage preceding anti-alias filtering and digitization. Use Value: 2000-V HBM ESD rating and ±100-mA surge tolerance eliminate need for discrete TVS devices; ceramic DIP package resists moisture ingress and thermal shock. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA211MDR | Lower 1.1 nV/√Hz noise, but higher 3.5-nA input bias current and only −40°C to +125°C rating | Better for wideband precision but unsuitable for >1-GΩ source impedances or extended cold-temperature operation | Select when ultra-low voltage noise dominates over input bias and temperature range requirements |
| AD8628TBRZ-REEL7 | Zero-drift architecture, 0.5 µV max VIO, but 120 nV/√Hz noise at 10 Hz and 125°C max operating temperature | Superior DC accuracy for chopper-stabilized applications, but higher low-frequency noise limits sub-Hz sensor use | Select when long-term DC stability is paramount and low-frequency noise is secondary |
Compared with OPA211MDR and AD8628TBRZ-REEL7, TLC2201AMD uniquely balances military-temperature operation, femtoampere-level input bias, and sub-30-nV/√Hz 10-Hz noise-making it irreplaceable in high-impedance, low-frequency, extreme-environment analog signal chains where all three attributes are simultaneously required.

FAQ
What is the maximum supply voltage for TLC2201AMD?
The TLC2201AMD supports a maximum supply voltage of ±8 V in split-supply mode or 16 V in single-supply mode, as specified in its Absolute Maximum Ratings table. Exceeding these limits risks permanent damage. Operation is fully characterized from ±2.3 V to ±8 V (or 4.6 V to 16 V), with optimal noise and offset performance observed at ±5 V or 5 V supplies.
Does TLC2201AMD support rail-to-rail input?
No, TLC2201AMD does not support rail-to-rail input. Its common-mode input voltage range extends to the negative rail (VDD−) but only up to VDD+ − 2.3 V under recommended operating conditions. This allows ground-referenced inputs but prohibits direct connection of IN+ or IN− to the positive supply rail without external attenuation or level-shifting.
What package types are available for TLC2201AMD?
TLC2201AMD is offered in four package variants: ceramic DIP (JG), plastic DIP (P), small-outline (D), and chip carrier (FK). All variants share identical electrical specifications and military-temperature qualification (−55°C to +125°C), with JG providing hermetic sealing and highest reliability for mission-critical deployments.
Is TLC2201AMD unity-gain stable?
TLC2201AMD is not unity-gain stable. Its phase margin is 45°–48° under unity-gain conditions with a 10-kΩ load and 100-pF capacitive load, as documented in the operating characteristics tables. For stable operation at gains ≥5, no compensation is needed; for gains <5, external compensation (e.g., feedback capacitor) is required to prevent oscillation.
How does the input offset voltage drift of TLC2201AMD compare to standard CMOS op-amps?
TLC2201AMD exhibits a temperature coefficient of input offset voltage of 0.5 µV/°C typical-significantly lower than most standard CMOS op-amps (often 2–5 µV/°C). This is achieved via Texas Instruments' silicon-gate Advanced LinCMOS™ process, which minimizes oxide-trap-related drift and ensures predictable, linear VIO behavior across its full −55°C to +125°C operating range.
