Product details
Overview
TLC2202ACDR from Texas Instruments is a dual, precision, low-noise rail-to-rail output operational amplifier using Advanced LinCMOS™ process. 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 high-impedance sensor signal conditioning in single- or split-supply data acquisition systems.
For engineers reviewing the TLC2202ACDR datasheet, TLC2202ACDR pinout, TLC2202ACDR application, or TLC2202ACDR equivalent, key selection criteria include input offset stability (0.5 µV/°C typ), rail-to-rail output swing (±4.7 V at ±5 V supply), ultra-low input bias current (1 pA typ), common-mode range extending to negative rail, and compatibility with low-voltage, low-power precision analog front-ends.
Technical Context
The TLC2202ACDR 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 JFET-like high-impedance inputs with bipolar-level DC precision.
It supports both single-supply (e.g., +5 V with GND) and split-supply (e.g., ±5 V) configurations, with common-mode input voltage range including the negative rail and rail-to-rail output swing-enabling full dynamic range utilization in low-voltage systems without level-shifting circuitry.
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 bridges. |
| Input Noise Density | 30 nV/√Hz max at 10 Hz - critical for low-frequency sensor amplification (e.g., thermocouples, strain gauges). |
| Rail-to-Rail Output | Swings within 200 mV of rails at ±5 V supply - maximizes usable output range in 3.3 V or 5 V systems. |
| Input Bias Current | 1 pA typ at 25°C - enables high-impedance source interfacing (e.g., pH electrodes, photodiode transimpedance). |
| Supply Voltage Range | ±2.3 V to ±8 V - supports operation from low-voltage battery-powered designs to industrial ±5 V rails. |
| Common-Mode Input Range | Includes negative rail (VDD−/GND) - allows direct sensing of signals referenced to ground in single-supply configurations. |
| Gain-Bandwidth Product | 1.9 MHz - sufficient for anti-aliasing filters, active instrumentation amps, and moderate-speed closed-loop control. |
Pinout & Package
TLCL2202ACDR is housed in an 8-pin SOIC (Small Outline Integrated Circuit) package (D suffix), surface-mount, tape-and-reel compatible (R suffix). Dimensions conform to JEDEC MS-012, body width 3.9 mm, lead pitch 1.27 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (Amplifier 1) | High-impedance node accepting differential input signal; accepts common-mode down to VDD−. |
| 2 | Non-Inverting Input (Amplifier 1) | High-impedance reference or sensor input; matched bias current minimizes offset error. |
| 3 | Output (Amplifier 1) | Rail-to-rail capable output driving loads ≥10 kΩ; short-circuit protected to ±50 mA. |
| 4 | VDD− / GND | Negative supply or ground reference; common return for both amplifiers and input common-mode range anchor. |
| 5 | Non-Inverting Input (Amplifier 2) | Independent high-Z input for second channel; electrically isolated from Amp 1 except shared supply pins. |
| 6 | Inverting Input (Amplifier 2) | Second differential input node; identical electrical specs to Pin 1. |
| 7 | Output (Amplifier 2) | Second rail-to-rail output; fully specified for same load and thermal conditions as Pin 3. |
| 8 | VDD+ | Positive supply rail; must be decoupled locally with 0.1 µF ceramic capacitor to minimize noise coupling. |
Key Features
| Feature | Design Value |
|---|---|
| Advanced LinCMOS™ Process | Silicon-gate technology delivering 0.5 µV/°C typical offset drift - reduces calibration frequency in field-deployed instruments. |
| Bipolar-Level DC Precision + JFET Noise Performance | Combines <500 µV offset with 30 nV/√Hz low-frequency noise - eliminates trade-off between precision and low-noise in sensor interfaces. |
| Rail-to-Rail Output Swing | Delivers >95% of full supply range (e.g., 4.7 V swing on ±5 V) - preserves SNR in ADC-driven systems without external level-shifting. |
| ESD Protection | Withstands 2000 V per MIL-PRF-38535 Method 3015.2 - reduces handling sensitivity during PCB assembly and test. |
| Surge Current Tolerance | Inputs/outputs withstand −100 mA transient surges without latch-up - improves robustness in noisy industrial environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision low-noise op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2188AIDR | Lower offset (25 µV max), lower noise (8.8 nV/√Hz @ 1 kHz), but higher supply current (420 µA/channel) and no rail-to-rail output. | Preferred for ultra-precision DC-coupled systems where offset dominates error budget; unsuitable where full output swing is required. | Select OPA2188AIDR when offset voltage <100 µV is mandatory and rail-to-rail output is not needed. |
| AD8628ARZ-REEL7 | Zero-drift architecture achieves 1 µV max offset and 0.005 µV/°C drift, but higher 1/f noise (25 nV/√Hz @ 0.1 Hz) and limited bandwidth (2.5 MHz). | Better for long-term DC stability in calibration equipment; less optimal for wideband sensor signals above 10 kHz. | Choose AD8628ARZ-REEL7 for metrology-grade zero-drift performance where low-frequency stability outweighs broadband noise. |
Compared with OPA2188AIDR and AD8628ARZ-REEL7, the TLC2202ACDR offers balanced precision, low-frequency noise, rail-to-rail output, and moderate power - making it optimal for cost-sensitive, battery-aware, medium-bandwidth sensor interfaces where full dynamic range and thermal stability are jointly critical.

FAQ
What is the maximum operating temperature range for the TLC2202ACDR?
The TLC2202ACDR is characterized for operation from 0°C to 70°C (C-suffix grade). Its absolute maximum junction temperature is 150°C, and storage temperature range extends from −65°C to 150°C. Thermal derating begins above 25°C ambient, with power dissipation reduced by 5.8 mW/°C for the SOIC-8 (D) package.
Does the TLC2202ACDR support single-supply operation?
Yes, the TLC2202ACDR fully supports single-supply operation. With VDD− connected to GND and VDD+ supplied (e.g., +5 V), its common-mode input range includes the negative rail (0 V), and output swings rail-to-rail - enabling direct interface with 3.3 V or 5 V ADCs without level-shifting circuitry.
What is the input bias current specification for the TLC2202ACDR?
The TLC2202ACDR has a typical input bias current of 1 pA at 25°C, with a maximum of 100 pA across the full operating temperature range (0°C to 70°C). This ultra-low value enables accurate amplification of signals from high-impedance sources such as piezoelectric sensors, pH electrodes, and photodiodes.
How does the noise performance of the TLC2202ACDR compare at low versus high frequencies?
The TLC2202ACDR exhibits 30 nV/√Hz maximum input voltage noise at 10 Hz and 12 nV/√Hz maximum at 1 kHz - reflecting classic 1/f noise roll-off typical of precision CMOS op-amps. Its peak-to-peak noise is 0.7 µV over 0.1–10 Hz, making it well-suited for DC-coupled, low-frequency sensor applications where flicker noise dominates.
Is the TLC2202ACDR pin-compatible with other devices in the TLC220x family?
Yes, the TLC2202ACDR shares the same SOIC-8 (D) package pinout with all TLC2202x variants (e.g., TLC2202BCDR, TLC2202CDR) and is functionally compatible with TLC2201x dual op-amps in the same package - though TLC2201 has different offset and noise specs. No PCB layout change is required when substituting within the TLC2202x series.
