Product details
Overview
TLC2201MLB from Texas Instruments is a precision, low-noise single-channel operational amplifier using Advanced LinCMOS™ process, delivering rail-to-rail output swing, 500 µV max input offset voltage, 30 nV/√Hz max input noise at 10 Hz, and full military temperature range (−55°C to 125°C). It serves as a high-impedance signal-conditioning front-end in single- or split-supply sensor interfaces and data acquisition systems.
For engineers reviewing the TLC2201MLB datasheet, TLC2201MLB pinout, TLC2201MLB application, or TLC2201MLB equivalent, key selection criteria include its guaranteed low-noise performance at sub-kHz frequencies, input bias current of 1 pA typ, common-mode input range extending to the negative rail, and robust ESD protection up to 2000 V per MIL-PRF-38535.
Technical Context
The TLC2201MLB implements a silicon-gate LinCMOS™ architecture that achieves superior input offset voltage stability over temperature (0.5 µV/°C typ) and time versus metal-gate alternatives. Its input stage includes JFET-like high impedance with bipolar-level DC precision, enabling stable operation in high-source-impedance transducer amplification.
It supports both single-supply (VDD = 4.6 V to 16 V) and split-supply (±2.3 V to ±8 V) configurations, with common-mode input voltage range spanning from VDD− to (VDD+ − 2.3 V), and rail-to-rail output swing delivering >4.7 V peak-to-peak into 10 kΩ load at ±5 V supply.

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision low-noise operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA211MDRG4 | Lower noise (1.1 nV/√Hz at 1 kHz), but higher input bias current (1.5 nA) and narrower temp range (−55°C to 125°C only for MD variant) | Preferred where ultra-low broadband noise dominates; less suitable for >100 MΩ source impedances | Select OPA211MDRG4 when system bandwidth exceeds 10 MHz and DC precision is secondary to noise floor |
| AD8628ARMZ | Zero-drift architecture; 0.5 µV max offset, but higher 1/f noise (250 nV p-p, 0.1–10 Hz) and limited output drive (20 mA) | Better for DC-stable integrators or zero-error nulling loops; not recommended for high-current sensor loads | Choose AD8628ARMZ when long-term DC stability outweighs low-frequency noise sensitivity |
Compared with TLC2201MLB, OPA211MDRG4 offers superior high-frequency noise performance but sacrifices input impedance compatibility, while AD8628ARMZ delivers near-zero offset drift at the cost of increased low-frequency noise and reduced output current capability-making TLC2201MLB optimal for balanced low-noise, high-Z, and ruggedized analog front-ends.

FAQ
What is the maximum supply voltage rating for TLC2201MLB?
The TLC2201MLB has an absolute maximum supply voltage rating of ±8 V for split-supply operation or 16 V for single-supply operation. Exceeding 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 this span for the TLC2201MLB.
Does TLC2201MLB support rail-to-rail input operation?
No, the TLC2201MLB does not support rail-to-rail input operation. Its common-mode input voltage range extends to the negative rail (VDD−) but only up to (VDD+ − 2.3 V) on the positive side. This design enables ground-referenced sensor interfacing while maintaining precision-confirmed in the "Recommended Operating Conditions" table of the TLC2201MLB datasheet.
What is the guaranteed input offset voltage specification for TLC2201MLB over temperature?
The TLC2201MLB guarantees a maximum input offset voltage of 500 µV at 25°C and 600 µV across its full operating range of −55°C to +125°C. Its temperature coefficient is specified at 0.5 µV/°C typical, ensuring predictable, bounded drift in precision DC-coupled circuits throughout the military temperature envelope.
Can TLC2201MLB be used in single-supply configurations?
Yes, the TLC2201MLB is fully specified for single-supply operation from 4.6 V to 16 V. Its common-mode input range includes the negative rail (ground), and its rail-to-rail output swing enables full utilization of the supply range-making it suitable for battery-powered or industrial 5 V/12 V systems without dual supplies.
How does the Advanced LinCMOS™ process benefit TLC2201MLB in long-term deployments?
The Advanced LinCMOS™ process in the TLC2201MLB provides exceptional input offset voltage stability over time and temperature-achieving 0.5 µV/°C typical drift and <0.005 µV/month long-term drift. This silicon-gate technology outperforms metal-gate alternatives in aging resistance, reducing recalibration needs in field-deployed systems like avionics or oilfield sensors where maintenance access is limited.
