Product details
Overview
TLC2201IP from Texas Instruments is a precision, low-noise single-channel operational amplifier using Advanced LinCMOS™ process. It delivers 500 µV max input offset voltage, 30 nV/√Hz max noise at 10 Hz, rail-to-rail output swing, and operates from −40°C to 85°C in plastic DIP (P) package. It serves high-impedance sensor signal conditioning in single-supply data acquisition systems.
For engineers reviewing the TLC2201IP datasheet, TLC2201IP pinout, TLC2201IP application, or TLC2201IP equivalent, key selection criteria include input bias current (1 pA typ), common-mode input range extending to negative rail, noise performance at sub-1 kHz frequencies, and guaranteed operation across industrial temperature range without derating.
Technical Context
The TLC2201IP implements a precision CMOS input stage with silicon-gate Advanced LinCMOS™ technology, enabling exceptional input offset voltage stability over time and temperature (0.5 µV/°C typ). Its architecture supports both single-supply (VDD = 5 V) and split-supply (±5 V) configurations while maintaining full rail-to-rail output swing and common-mode input voltage range inclusive of the negative rail.
It features internal ESD protection rated to 2000 V (MIL-PRF-38535, Method 3015.2) and robust input/output surge tolerance (−100 mA). The device is not unity-gain stable by default - phase margin is specified at 45°–48° under 10 kΩ//100 pF load, requiring careful compensation for closed-loop stability at high gains.
Key Specifications

| Input Bias Current | 1 pA typ at 25°C; enables use with >1 GΩ source impedances without significant DC error |
| Common-Mode Input Range | Includes negative rail (VDD−/GND); allows direct interfacing to ground-referenced transducers in single-supply systems |
| Rail-to-Rail Output | Swings within 200 mV of supply rails (±4.7 V @ ±5 V); maximizes dynamic range in low-voltage ADC driver applications |

Pinout & Package
Package: Plastic Dual-In-Line (P), 8-pin, through-hole. Body dimensions: 9.27 mm × 6.35 mm × 3.3 mm (JEDEC MS-001). RoHS-compliant lead finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (IN−) | Differential input node; high-impedance CMOS gate; requires matched trace impedance for noise rejection |
| 2 | Non-Inverting Input (IN+) | Differential input node; referenced to system ground or bias network; accepts signals down to VDD− |
| 3 | Output (OUT) | Class AB output stage; drives ≥10 kΩ loads; limited to ±50 mA short-circuit current |
| 4 | Ground / Negative Supply (VDD−/GND) | Power return path; must be low-impedance; shared reference for input common-mode and output swing |
| 5 | No Connect (NC) | Internally unconnected; no electrical function; leave floating or tie to ground per layout best practice |
| 6 | Positive Supply (VDD+) | Primary power rail; decoupling capacitor (0.1 µF ceramic) required within 5 mm of pin |
| 7 | No Connect (NC) | Internally unconnected; no electrical function; avoid routing sensitive traces nearby |
| 8 | No Connect (NC) | Internally unconnected; no electrical function; maintain clearance from thermal vias |
Key Features

|---|---|
Use Scenario: Amplifying µV-level Wheatstone bridge outputs from metallic strain gauges in structural health monitoring. IC Role / Device Role / Timing Role: Precision DC-coupled instrumentation amplifier core (configured as non-inverting gain stage). Use Value: 1 pA input bias avoids loading high-Z bridge arms; 30 nV/√Hz noise preserves resolution below 10 Hz where mechanical vibration dominates. | Use Scenario: Cold-junction-compensated amplification of Type-K thermocouple outputs (−5 mV to +40 mV) over −40°C to +85°C ambient.

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA227PA | Bipolar input; 10 µV max VOS, 10 nV/√Hz @ 1 kHz, but 10 nA IIB; requires dual supply | Better DC precision and broadband noise, but unsuitable for >100 kΩ source impedances or single-supply use | Select OPA227PA only when ultra-low VOS and high-speed settling dominate over input impedance and supply flexibility |
| AD8628ARZ | Zero-drift auto-zero; 1 µV max VOS, 0.1 pA IIB, but 45 nV/√Hz @ 10 Hz; higher quiescent current (1.2 mA) | Superior DC accuracy and bias current for nanovolt-level measurements, but higher low-frequency noise compromises sub-10 Hz resolution | Select AD8628ARZ when long-term drift and offset nulling are critical, and 10 Hz noise floor is acceptable |
Compared with OPA227PA and AD8628ARZ, the TLC2201IP uniquely balances ultra-low input bias current (1 pA), usable low-frequency noise (30 nV/√Hz @ 10 Hz), rail-to-rail output, and industrial temperature range - making it optimal for high-Z, battery-conscious, single-supply sensor interfaces where moderate DC precision suffices.

FAQ
What is the maximum supply voltage for the TLC2201IP?
The TLC2201IP supports a maximum supply voltage of ±8 V in split-supply mode or 16 V in single-supply mode. Absolute maximum ratings specify VDD+ ≤ +8 V and VDD− ≥ −8 V relative to midpoint; exceeding these risks permanent damage. For reliable operation, TI recommends staying within ±2.3 V to ±8 V (split) or 4.6 V to 16 V (single) as defined in recommended operating conditions. The TLC2201IP must never be operated beyond these limits even momentarily.
Does the TLC2201IP support true rail-to-rail input?
No, the TLC2201IP does not support rail-to-rail input. Its common-mode input voltage range extends to the negative rail (VDD−/GND) but only up to VDD+ − 2.3 V under recommended conditions - meaning it cannot accept signals within 2.3 V of the positive supply. However, its rail-to-rail output capability (swinging within 200 mV of both rails) remains fully functional. This asymmetry makes the TLC2201IP ideal for ground-referenced sensor inputs in single-supply systems but unsuitable for inputs near VDD+ without level shifting.
Can the TLC2201IP drive a 100 pF capacitive load directly?
The TLC2201IP is not optimized for direct 100 pF capacitive loads. Its phase margin drops to 45°–48° under 10 kΩ resistive + 100 pF capacitive load, risking instability and overshoot in unity-gain configurations. TI's datasheet explicitly characterizes slew rate and bandwidth under CL = 100 pF, confirming marginal stability. For reliable operation, add a small isolation resistor (10–50 Ω) between output and capacitance, or use a dedicated buffer stage. Never drive 100 pF without compensation if step response fidelity or settling time is critical.
What is the typical input bias current of the TLC2201IP at 85°C?
The typical input bias current of the TLC2201IP remains 1 pA at 25°C, and the datasheet specifies a maximum of 100 pA across the full −40°C to +85°C operating range. While temperature increases bias current in CMOS devices, the Advanced LinCMOS™ process used in the TLC2201IP suppresses this effect significantly - ensuring bias stays well below 10 pA at 85°C in most units. Designers should use the 100 pA max value for worst-case analysis in high-impedance circuits, especially those with >100 MΩ source resistance.
Is the TLC2201IP pin-compatible with other devices in the TLC220x family?
Yes, the TLC2201IP shares identical 8-pin DIP (P) pinout with all single-channel variants in the TLC220x family, including TLC2201AC, TLC2201BC, TLC2201C, and TLC2201AIP. Pin functions (IN−, IN+, OUT, VDD−/GND, VDD+) and NC assignments are consistent across all P-package versions. This allows drop-in replacement between grades (e.g., upgrading from C-suffix to I-suffix for extended temperature) without PCB modification - provided the application tolerates differences in VOS, noise, and CMRR specifications.
