Product details
Overview
TLC2202CP from Texas Instruments is a dual precision, low-noise operational amplifier using Advanced LinCMOS™ process, designed for high-impedance signal conditioning in single- or split-supply configurations. It delivers rail-to-rail output swing, 500 µV max input offset voltage, 30 nV/√Hz max input noise at 10 Hz, and operates across 0°C to 70°C. Used in sensor front-ends, medical instrumentation, and precision data acquisition systems.
For engineers reviewing the TLC2202CP datasheet, TLC2202CP pinout, TLC2202CP application, or TLC2202CP equivalent, this page provides verified specifications, package mapping (8-pin PDIP), functional pin roles, real-world use cases, and two validated alternative parts with documented technical and application differences.
Technical Context
The TLC2202CP integrates two independent precision op-amps on a single die using silicon-gate Advanced LinCMOS™ technology, enabling superior input offset voltage stability over temperature and time versus metal-gate processes. Its input stage includes common-mode range extending to the negative rail and supports ±2.3 V to ±8 V dual supply or +4.6 V to +16 V single supply operation.
Each amplifier features JFET-like input impedance (>10¹² Ω) combined with bipolar-level DC precision, low input bias current (1 pA typ), and internal ESD protection rated to 2000 V (MIL-PRF-38535 Method 3015.2). The device withstands −100-mA surge currents at inputs/outputs without latch-up.
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 amplifiers. |
| Input Noise Voltage | 30 nV/√Hz max at 10 Hz - enables low-frequency signal integrity in EEG, strain gauge, and thermocouple interfaces. |
| Rail-to-Rail Output | Swings within 200 mV of rails at ±5 V supply - maximizes dynamic range in low-voltage single-supply systems. |
| Input Bias Current | 1 pA typical at 25°C - critical for high-Z source applications like photodiode transimpedance amps. |
| Supply Voltage Range | ±2.3 V to ±8 V (dual) or +4.6 V to +16 V (single) - supports flexible power architecture in industrial and portable equipment. |
| Common-Mode Input Range | Includes negative rail - allows direct interfacing with ground-referenced sensors without level-shifting circuitry. |
| Gain-Bandwidth Product | 1.9 MHz - sufficient for anti-aliasing filters, active instrumentation amplifiers, and moderate-speed closed-loop control. |
Pinout & Package
Package: Plastic Dual-In-Line (PDIP-8), 0.3-inch body width, through-hole mounting. RoHS-compliant lead finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting input of amplifier A | High-impedance node accepting differential feedback or signal inversion; referenced to VDD−/GND. |
| 2 | Non-inverting input of amplifier A | High-Z input for reference or sensor connection; common-mode range extends to negative rail. |
| 3 | Output of amplifier A | Capable of ±50 mA short-circuit current; rail-to-rail swing supports full utilization of supply headroom. |
| 4 | VDD− / Ground | Power return for dual supply or system ground for single supply; shared reference for both amplifiers. |
| 5 | Non-inverting input of amplifier B | Independent high-Z input; electrically isolated from amplifier A except via shared supply and substrate. |
| 6 | Inverting input of amplifier B | Accepts feedback network or inverted signal path; identical electrical characteristics to Pin 1. |
| 7 | Output of amplifier B | Functionally identical to Pin 3; supports independent load driving up to 50 mA sink/source. |
| 8 | VDD+ | Positive supply rail; must be ≥ |VDD−| for symmetric operation or used as sole supply in single-rail mode. |
Key Features
| Feature | Design Value |
|---|---|
| Advanced LinCMOS™ Process | Silicon-gate technology delivering 0.5 µV/°C typical input offset drift - reduces calibration frequency in field-deployed instruments. |
| Low-Frequency Noise Performance | 30 nV/√Hz max at 10 Hz - directly improves signal-to-noise ratio in sub-100-Hz biomedical and geophysical sensing. |
| Rail-to-Rail Output Stage | Delivers >4.7 V swing with ±5 V supplies - eliminates need for level-shifting in 5 V microcontroller-based data loggers. |
| Input Overvoltage Withstand | Withstands −100 mA surge without latch-up - enhances robustness in noisy industrial environments with inductive transients. |
| ESD Protection | 2000 V HBM rating per MIL-PRF-38535 - reduces handling sensitivity during PCB assembly and test. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2277PA | Lower VIO (10 µV max), higher cost, SO-8 only - no PDIP option; 0.1 µV/°C drift vs. TLC2202CP's 0.5 µV/°C. | Better for ultra-precision DC-coupled systems (e.g., laboratory calibrators); not drop-in due to different pinout and package. | Select when VIO and drift dominate performance requirements and PDIP is not mandatory. |
| LMV722MMX | Higher noise (20 nV/√Hz @ 1 kHz), wider GBW (10 MHz), same PDIP-8 footprint - but only single-supply rated (2.7–5.5 V). | Suitable for higher-speed, lower-voltage portable designs; lacks dual-supply flexibility and rail-to-rail input. | Choose for battery-powered 3.3 V systems needing faster response, accepting higher low-frequency noise. |
Compared with OPA2277PA and LMV722MMX, the TLC2202CP uniquely balances low 10-Hz noise, rail-to-rail output, dual-supply capability, and PDIP-8 availability - making it optimal for legacy industrial and medical designs requiring field-serviceable through-hole assembly.

FAQ
What is the maximum operating temperature range for the TLC2202CP?
The TLC2202CP is characterized for operation from 0°C to +70°C (C-suffix grade). It is not rated for extended industrial (−40°C to +85°C) or military (−55°C to +125°C) temperature ranges - those require TLC2202IP or TLC2202MP variants. Thermal derating begins above 70°C per the dissipation rating table in the datasheet.
Does the TLC2202CP support true rail-to-rail input operation?
No - the TLC2202CP features rail-to-rail *output* swing but its common-mode input voltage range extends only to the negative rail (VDD−/GND), not to the positive rail. The upper limit is VDD+ − 2.3 V under recommended conditions. For full rail-to-rail input, consider newer TI devices like OPA2333 or TLV2462.
Can the TLC2202CP drive capacitive loads without instability?
The TLC2202CP has a phase margin of 48° at unity gain with 100 pF load and 10 kΩ RL. It remains stable with ≤100 pF capacitive loads under standard conditions; larger loads require isolation resistors or external compensation per Figure 10 in the datasheet. Avoid direct connection to >1 nF ADC input capacitors without series resistance.
What is the typical supply current consumption of the TLC2202CP?
The TLC2202CP draws 1.8–2.7 mA per amplifier (3.6–5.4 mA total) at 25°C with no load and ±5 V supplies. Supply current increases slightly with temperature and supply voltage - up to 2.7 mA per amp at full 0°C to 70°C range. This makes it suitable for low-power precision applications where <6 mA total quiescent current is acceptable.
Is the TLC2202CP pin-compatible with other dual op-amps in PDIP-8 packages?
No - the TLC2202CP uses a non-standard pinout: Pins 1/2/3 = Amp A (−/+/OUT), Pin 4 = VDD−/GND, Pins 5/6/7 = Amp B (+/−/OUT), Pin 8 = VDD+. This differs from industry-standard dual op-amps like LM358 (Pins 1/2/3 = OUT/−/+ for Amp A) and requires PCB layout adaptation. Always verify pin mapping before substitution.
