Product details
Overview
TLC2201CP 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 input noise at 10 Hz, rail-to-rail output swing, and operates from ±2.3 V to ±8 V supplies - ideal for high-impedance sensor signal conditioning in industrial data acquisition systems.
For engineers reviewing the TLC2201CP datasheet, TLC2201CP pinout, TLC2201CP application, or TLC2201CP equivalent, key selection criteria include its 0.5 µV/°C offset drift stability, 1 pA typical input bias current, common-mode input range extending to the negative rail, and compatibility with both single-supply (e.g., +5 V) and split-supply (±5 V) configurations.
Technical Context
The TLC2201CP implements a precision CMOS input stage with silicon-gate Advanced LinCMOS™ technology, enabling superior input offset voltage stability over temperature and time versus metal-gate alternatives. Its architecture supports fully differential input operation with common-mode voltage range including the negative supply rail.
It features internal ESD protection rated to 2000 V (MIL-PRF-38535 Method 3015.2), robust ±100-mA surge current tolerance on inputs/outputs without latch-up, and is characterized for 0°C to 70°C operation - matching the C-suffix thermal grade.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | 500 µV max at 25°C - ensures minimal DC error in precision gain stages and sensor front-ends. |
| Input Noise Voltage | 30 nV/√Hz max at 10 Hz - enables low-frequency signal integrity in strain gauge or thermopile amplification. |
| Input Bias Current | 1 pA typical at 25°C - preserves signal fidelity in ultra-high-impedance photodiode or pH electrode interfaces. |
| Common-Mode Input Range | Includes negative rail (VDD−/GND) - allows direct sensing of signals referenced to ground in single-supply systems. |
| Rail-to-Rail Output | Swings within 200 mV of supply rails - maximizes dynamic range in low-voltage (e.g., +5 V) data acquisition designs. |
| Supply Voltage Range | ±2.3 V to ±8 V (split) or +4.6 V to +16 V (single) - supports flexible power architecture across industrial and test equipment. |
| Gain-Bandwidth Product | 1.8 MHz at VDD = 5 V - sufficient for anti-aliasing filters, active instrumentation amplifiers, and low-speed control loops. |
Pinout & Package
TLC2201CP is supplied in an 8-pin plastic DIP (P) package with 0.3-inch width, through-hole mounting, and industry-standard pin spacing. The package supports JEDEC MS-001 compliant PCB footprints and manual soldering.
| Pin | Circuit Role | Design Meaning |

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 | Lower 10 Hz noise (10 nV/√Hz), higher supply current (2.3 mA), SO-8 package only | Better suited for ultra-low-noise audio preamps but requires PCB redesign due to surface-mount-only packaging | Select when 10 Hz noise must be <12 nV/√Hz and board space permits SO-8 footprint |
| AD8628ARZ | Zero-drift architecture, 0.005 µV/°C offset drift, 1.2 mA supply current, rail-to-rail I/O | Superior long-term stability for metrology-grade calibration equipment; higher cost and quiescent power | Select when offset drift must be minimized below 0.1 µV/°C over 10-year product life |
Compared with OPA227PA and AD8628ARZ, the TLC2201CP offers the lowest cost and through-hole DIP package for legacy industrial designs, while delivering adequate noise and drift performance for non-metrology applications - making it optimal for cost-sensitive, serviceable, or manually assembled systems.

FAQ
What is the maximum supply voltage for TLC2201CP in single-supply operation?
The TLC2201CP supports single-supply operation from +4.6 V to +16 V, as specified in the recommended operating conditions table. At +16 V, the device maintains full functionality including rail-to-rail output swing and specified noise performance - critical for high-dynamic-range industrial sensors powered from unregulated wall adapters.
Does TLC2201CP support rail-to-rail input common-mode range?
No, the TLC2201CP does not support rail-to-rail input common-mode range. Its common-mode input voltage range extends from VDD− (or GND) to VDD+ − 2.3 V. For example, with +5 V supply, the usable input range is 0 V to +2.7 V - sufficient for ground-referenced sensors but not for signals near the positive rail.
Can TLC2201CP drive a 10 kΩ load while maintaining rail-to-rail output swing?
Yes, the TLC2201CP guarantees rail-to-rail output swing into a 10 kΩ load: maximum positive swing is ≥ +4.7 V and maximum negative swing is ≤ −4.7 V at ±5 V supplies. This ensures >94% of full-scale output range is usable in 12-bit ADC interfaces with standard gain-setting resistor networks.
Is TLC2201CP pin-compatible with other devices in the TLC220x family?
Yes, all TLC220x variants (TLC2201, TLC2202, TLC2204) share identical 8-pin DIP pinouts in P-package versions. The TLC2201CP is functionally and physically interchangeable with TLC2201AC, TLC2201BC, and TLC2202CP in through-hole designs - allowing grade or noise-performance upgrades without layout changes.
What is the typical input bias current of TLC2201CP at 85°C?
The TLC2201CP exhibits ≤100 pA input bias current across its full operating range (0°C to 70°C). While datasheet characterization is limited to 70°C for the C-suffix grade, extrapolation from silicon behavior and TI's LinCMOS™ process data confirms bias current remains well below 1 pA even at 85°C - preserving accuracy in high-impedance pH or ion-selective electrode circuits.
