Product details
Overview
TLC2202ACD from Texas Instruments is a dual-channel, 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 voltage 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 is used in high-impedance sensor signal conditioning, medical instrumentation front-ends, and precision single-supply data acquisition systems.
For engineers reviewing the TLC2202ACD datasheet, TLC2202ACD pinout, TLC2202ACD application, or TLC2202ACD equivalent, this page provides verified package mapping (SOIC-8), confirmed dual-amplifier topology, rail-to-rail output swing specification, common-mode input range including negative rail, and validated alternative options for low-noise precision op-amp selection.
Technical Context
The TLC2202ACD implements two independent precision amplifiers on a single die using silicon-gate Advanced LinCMOS™ process, enabling superior input offset voltage stability over temperature (0.5 µV/°C typ) and time versus metal-gate alternatives. Its input stage includes JFET-like high impedance (1 pA typ input bias current) with bipolar-level DC precision.
It supports both split-supply (±2.3 V to ±8 V) and single-supply operation with common-mode input voltage range extending to the negative rail (VDD−/GND), and rail-to-rail output swing delivering ±4.7 V into 10 kΩ at ±5 V supply. The device features internal ESD protection rated to 2000 V (MIL-PRF-38535, Method 3015.2) and 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 - enables accurate DC-coupled amplification of mV-level sensor signals without significant baseline error |
| Input Voltage Noise | 30 nV/√Hz max at 10 Hz - critical for low-frequency precision applications like strain gauge or thermopile amplification |
| Rail-to-Rail Output | Swings within 300 mV of supply rails at ±5 V - maximizes dynamic range in single-supply systems (e.g., 0–5 V ADC interfaces) |
| Common-Mode Input Range | Includes VDD−/GND - allows direct sensing of signals referenced to ground in single-supply configurations |
| Supply Current | 2.7 mA max per amplifier - balances low-noise performance with moderate power consumption for portable instrumentation |

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 (1 mA/ch) and no rail-to-rail output | Better DC accuracy for µV-level measurements; unsuitable where output must swing to GND in single-supply designs | Select when ultra-low offset dominates over output swing and power constraints |
| AD8628ARZ-REEL7 | Zero-drift architecture, 1 µV max offset, 11 nV/√Hz @ 1 kHz, rail-to-rail output, but limited GBW (2.5 MHz) and higher cost | Superior long-term stability for calibration-critical systems; less suitable for wideband sensor excitation or fast settling | Select when zero-drift stability outweighs bandwidth needs and budget permits premium pricing |
Compared with TLC2202ACD, OPA2188AIDR trades rail-to-rail output and lower power for superior DC precision, while AD8628ARZ-REEL7 delivers near-zero drift at higher cost and reduced bandwidth-making TLC2202ACD optimal for balanced low-noise, rail-to-rail, and cost-sensitive industrial signal chains.

FAQ
What is the maximum supply voltage range for the TLC2202ACD?
The TLC2202ACD supports a total supply voltage range of ±2.3 V to ±8 V for split-supply operation, or 4.6 V to 16 V for single-supply use. Absolute maximum ratings specify VDD+ ≤ +8 V and VDD− ≥ −8 V. Exceeding these limits risks permanent damage, and operation above ±8 V violates the recommended operating conditions defined in the SLOS175B datasheet.
Does the TLC2202ACD support true rail-to-rail input?
No, the TLC2202ACD does not feature 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. This means it accepts inputs down to ground in single-supply setups but cannot handle signals at the positive rail-unlike rail-to-rail input op-amps. The TLC2202ACD's key strength is rail-to-rail *output* swing.
What is the guaranteed input offset voltage specification for the TLC2202ACD?
The TLC2202ACD has a maximum input offset voltage of 500 µV at 25°C and 650 µV across the full 0°C to 70°C operating range. This value applies specifically to the "A" grade variant (TLC2202A), as confirmed in the "TLC2202 AVAILABLE OPTIONS" table and electrical characteristics section of the SLOS175B datasheet.
Can the TLC2202ACD drive capacitive loads directly?
The TLC2202ACD is characterized for stability with 100 pF capacitive load at unity gain (phase margin = 48°). Driving larger capacitive loads (>100 pF) without isolation resistance may cause peaking or oscillation. For loads exceeding 100 pF, a series resistor (typically 10–100 Ω) between the output and capacitance is recommended to maintain stability, as noted in standard op-amp layout guidelines.
Is the TLC2202ACD pin-compatible with other devices in the TLC220x family?
Yes, the TLC2202ACD shares identical SOIC-8 (D package) pinout with all TLC2202 variants (e.g., TLC2202BCD, TLC2202CD) and is functionally compatible with TLC2201-series dual op-amps in the same package-though TLC2201 has different performance grades and noise specs. Pin compatibility enables drop-in replacement within the same suffix family, provided thermal and electrical requirements are met.
