Product details
Overview
TLC2202BCP from Texas Instruments is a dual, precision, low-noise rail-to-rail output operational amplifier fabricated in Advanced LinCMOS™ technology. It delivers 500 µV max input offset voltage, 30 nV/√Hz max input noise at 10 Hz, and 12 nV/√Hz max at 1 kHz, operating from ±2.3 V to ±8 V supplies across 0°C to 70°C. It serves signal-conditioning roles in high-impedance sensor interfaces and single-supply data acquisition systems.
For engineers reviewing the TLC2202BCP datasheet, TLC2202BCP pinout, TLC2202BCP application, or TLC2202BCP equivalent, key selection criteria include its B-grade noise performance, rail-to-rail output swing, common-mode input range extending to the negative rail, low 1 pA typical input bias current, and compatibility with both single- and split-supply configurations.
Technical Context
The TLC2202BCP implements a dual-channel architecture with fully independent amplifiers sharing only power supply connections. Each channel features silicon-gate Advanced LinCMOS™ input stages enabling superior input offset voltage stability over temperature (0.5 µV/°C typ) and time, plus ultra-low input bias current (1 pA typ at 25°C).
Its design supports operation with common-mode input voltage down to the negative rail (VDD−/GND), rail-to-rail output swing (±4.7 V min at ±5 V supplies), and robust ESD protection (2000 V per MIL-PRF-38535 Method 3015.2), making it suitable for direct interfacing with transducers and ADC drivers in noisy industrial environments.
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 accurate amplification of low-frequency microvolt-level signals (e.g., thermocouples, strain gauges). |
| Rail-to-Rail Output | Swings within 200 mV of supply rails at ±5 V - maximizes dynamic range in single-supply systems without level-shifting circuitry. |
| Common-Mode Input Range | Includes VDD−/GND - allows direct connection of grounded sensors or reference-based inputs without external bias networks. |
| Supply Voltage Range | ±2.3 V to ±8 V - supports flexible power architectures including battery-powered and industrial ±5 V systems. |
| Input Bias Current | 1 pA typ at 25°C - minimizes voltage drop across high-impedance sources (e.g., pH electrodes, photodiodes). |
| Operating Temperature | 0°C to 70°C (C-suffix) - qualified for commercial-grade embedded instrumentation and test equipment. |

Applications
| Strain Gauge Signal Conditioning | Thermocouple Amplification |
|---|---|
|
Use Scenario: Amplifying mV-level Wheatstone bridge outputs from metal foil strain gauges in load cells and pressure sensors. IC Role / Device Role / Timing Role: Precision instrumentation amplifier front-end with low noise and near-zero input bias current to avoid bridge imbalance errors. Use Value: 30 nV/√Hz noise floor preserves resolution of <1 µε mechanical strain; rail-to-rail output drives 12-bit SAR ADCs directly. |
Use Scenario: Cold-junction compensation and low-drift amplification of Type-K thermocouple outputs (≈41 µV/°C) in HVAC controllers. IC Role / Device Role / Timing Role: High-input-impedance, low-offset amplifier with common-mode range to ground for direct thermocouple connection. Use Value: 500 µV max VIO contributes <12°C error at 25°C; 0.5 µV/°C drift limits thermal EMF-induced drift to <0.1°C/°C ambient change. |
| Single-Supply Data Acquisition | Industrial Sensor Interface |
|
Use Scenario: Buffering and scaling analog outputs from 4–20 mA loop-powered sensors into 0–3.3 V ranges for microcontroller ADCs. IC Role / Device Role / Timing Role: Rail-to-rail I/O op-amp configured as unity-gain buffer and level shifter in 3.3 V or 5 V systems. Use Value: Output swings to within 200 mV of GND and VDD - enables full utilization of 10-bit+ ADC input range without external biasing. |
Use Scenario: Interfacing high-impedance pH electrodes (10⁹–10¹² Ω) to analog front-ends in water quality analyzers. IC Role / Device Role / Timing Role: Ultra-low-input-bias-current amplifier minimizing electrode polarization and measurement drift. Use Value: 1 pA typical input bias current prevents >1 mV error across 1 GΩ source impedance - critical for stable pH readings over minutes. |
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 10 µV max VIO but higher 10 nV/√Hz noise at 1 kHz; bipolar input (2 nA IB); SO-8 package only. | Preferred where ultra-low offset dominates over noise; unsuitable for high-Z pH or piezoelectric sensors due to IB. | Select OPA2277PA when offset-critical DC precision outweighs noise and input impedance requirements. |
| MCP6022-I/P | Higher 3 mV max VIO; 14 nV/√Hz noise at 1 kHz; rail-to-rail I/O; 2.7–6 V single-supply only; DIP-8 available. | Cost-optimized alternative for non-critical industrial monitoring where ±5 V operation and sub-µV offset are not required. | Choose MCP6022-I/P for budget-sensitive, single-supply applications with relaxed DC accuracy needs. |
Compared with OPA2277PA and MCP6022-I/P, the TLC2202BCP uniquely balances B-grade low-frequency noise, rail-to-rail output, true ground-sensing input, and DIP-8 through-hole packaging - making it optimal for legacy-compatible, high-impedance, low-drift analog signal chains.

FAQ
What is the maximum supply voltage rating for the TLC2202BCP?
The TLC2202BCP has an absolute maximum supply voltage rating of ±8 V across VDD+ and VDD− terminals. Operation beyond this limit risks permanent damage. Recommended operating range is ±2.3 V to ±8 V, with full specification compliance guaranteed across that span. The device's internal protection circuits do not extend safe operation beyond these limits.
Does the TLC2202BCP support single-supply operation?
Yes, the TLC2202BCP is fully specified for single-supply operation. When used with VDD− tied to ground and VDD+ at +5 V (or +3.3 V to +16 V), its common-mode input range extends to ground and its output swings rail-to-rail - enabling direct interfacing with microcontroller ADCs and other 0–VDD referenced circuitry without level-shifting components.
What does "B-grade" mean for the TLC2202BCP noise specification?
"B-grade" indicates that the TLC2202BCP is 100% tested for low-frequency noise performance: 30 nV/√Hz max at 10 Hz and 12 nV/√Hz max at 1 kHz. This grade distinguishes it from the standard C-grade (35/15 nV/√Hz) and A-grade (20/8 nV/√Hz), providing verified noise performance for demanding sensor applications without requiring binning or sampling verification.
Can the TLC2202BCP drive capacitive loads directly?
The TLC2202BCP is stable with capacitive loads up to 100 pF when driving into RL = 10 kΩ, as confirmed by phase margin testing (48° at unity gain). For larger capacitive loads (e.g., ADC input capacitance >100 pF or cable capacitance), external isolation resistance (≥100 Ω) is recommended to maintain stability and prevent peaking or oscillation in closed-loop configurations.
Is the TLC2202BCP pin-compatible with other devices in the TLC220x family?
Yes - all TLC220x dual op-amps in the 8-pin DIP (P), SOIC (D), and PS packages share identical pinouts: Pins 1/7 are outputs, Pins 2/6 are inverting inputs, Pins 3/5 are non-inverting inputs, Pin 4 is VDD−/GND, and Pin 8 is VDD+. This allows direct substitution between TLC2201, TLC2202, and TLC2204 variants in the same package, provided electrical specifications meet the application's requirements.
