Product details
Overview
TLC2262CD from Texas Instruments is a dual rail-to-rail output operational amplifier in an 8-pin SOIC (D) package, designed for precision signal conditioning in single- or split-supply systems. It delivers 12 nV/√Hz input noise at 1 kHz, 1 pA typical input bias current, and 500 µA maximum supply current per amplifier, enabling high-fidelity sensor interfacing in battery-powered instrumentation.
For engineers reviewing the TLC2262CD datasheet, TLC2262CD pinout, TLC2262CD application, or TLC2262CD equivalent, this page provides verified electrical specifications, validated dual-amplifier pin configuration, real-world use cases in ADC driver and piezoelectric transducer circuits, and two confirmed alternative parts with documented functional trade-offs.
Technical Context
The TLC2262CD uses Advanced LinCMOS™ process technology to achieve rail-to-rail output swing while maintaining low input bias current and low noise-critical for high-impedance source amplification. Its common-mode input voltage range extends to the negative rail, supporting true single-supply operation down to 4.4 V total supply.
This device operates across 0°C to 70°C and is fully characterized at both 5 V single-supply and ±5 V split-supply conditions. It exhibits 0.55 V/µs slew rate, 0.71 MHz gain-bandwidth product, and 70 dB minimum CMRR-making it suitable for medium-speed, precision analog front-ends where power efficiency and dynamic range are jointly constrained.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current | 500 µA max per amplifier - enables multi-channel, low-power portable instrumentation without thermal derating. |
| Input Bias Current | 1 pA typ - preserves signal integrity when amplifying from >1 GΩ sources like piezoelectric sensors. |
| Input Noise Voltage | 12 nV/√Hz at 1 kHz - supports high-resolution measurement of microvolt-level signals in medical or test equipment. |
| Rail-to-Rail Output | Swing within 10 mV of both rails at 100 µA load - maximizes usable dynamic range into ADCs with 0–5 V input spans. |
| Common-Mode Input Range | Includes negative rail (VDD–) - allows direct sensing of ground-referenced signals in single-supply configurations. |
| Offset Voltage | 2500 µV max at 25°C - sufficient for non-critical DC-coupled gain stages where trimming is not required. |
| Slew Rate | 0.55 V/µs - supports stable closed-loop operation up to ~185 kHz full-power bandwidth at 2 VPP. |
Pinout & Package
Package: 8-pin SOIC (D), surface-mount, tape-and-reel compatible (TLC2262CDR variant available).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Amplifier 1 output - drives loads up to ±50 mA; rail-to-rail swing enables direct interface to SAR ADC reference inputs. |
| 2 | IN1– | Inverting input of Amp1 - high-impedance node (10¹² Ω) requiring guarded layout for low-noise performance. |
| 3 | IN1+ | Non-inverting input of Amp1 - accepts common-mode voltages from VDD– to VDD+ –1.5 V in all operating conditions. |
| 4 | VDD– / GND | Negative supply or ground reference - serves as return path for both amplifiers; must be low-impedance for noise immunity. |
| 5 | IN2+ | Non-inverting input of Amp2 - electrically isolated from Amp1; supports independent dual-channel signal paths. |
| 6 | IN2– | Inverting input of Amp2 - matched input characteristics to Pin 2; enables differential pair or independent gain stages. |
| 7 | OUT2 | Amplifier 2 output - identical AC/DC specs to OUT1; allows simultaneous processing of two analog channels. |
| 8 | VDD+ | Positive supply - accepts 4.4 V to 16 V single-supply or ±2.2 V to ±8 V split-supply; internal ESD protection rated to ±2 kV HBM. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output | Delivers full 0–5 V swing at 100 µA load on 5 V supply - eliminates level-shifting circuitry before 12-bit+ ADCs. |
| Low input bias current | 1 pA typical - reduces voltage error across 10 MΩ source impedances to <10 µV, critical for pH or photodiode amps. |
| Low noise architecture | 12 nV/√Hz at 1 kHz - 3× lower than TLC27M2, enabling clean amplification of weak signals without post-filtering. |
| Single- and split-supply support | Fully specified from 4.4 V to 16 V single or ±2.2 V to ±8 V dual - simplifies design reuse across industrial and portable platforms. |
| High CMRR & PSRR | 70 dB min CMRR, 80 dB min PSRR - rejects supply ripple and common-mode interference in noisy embedded environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLC2262ACD | 950 µV max input offset voltage (vs. 2500 µV for TLC2262CD); same package, pinout, and speed. | Required for precision DC-coupled gain stages where offset-induced error must stay below 0.5 LSB in 12-bit systems. | Select TLC2262ACD when offset-critical signal chains demand guaranteed ≤950 µV VIO over full temperature range. |
| TLV2432IDR | Higher slew rate (1.5 V/µs), lower quiescent current (23 µA), but only 65 dB CMRR and no guaranteed rail-to-rail input. | Better for ultra-low-power, AC-coupled audio or sensor interfaces where DC accuracy is secondary to battery life. | Choose TLV2432IDR only if supply current <25 µA is mandatory and input common-mode range beyond VDD– is unnecessary. |
Compared with TLC2262ACD, the TLC2262CD trades guaranteed low offset for broader availability and lower cost in commercial-temp applications; versus TLV2432IDR, it prioritizes DC precision and noise performance over micropower operation-making it optimal for mid-speed, battery-operated instrumentation requiring consistent accuracy.

FAQ
What is the maximum supply voltage for the TLC2262CD?
The TLC2262CD supports a maximum total supply voltage of 16 V in single-supply mode (VDD+ to VDD–/GND) or ±8 V in split-supply mode. Absolute maximum ratings specify ±8 V on each supply rail, with continuous operation recommended within ±2.2 V to ±8 V for reliable performance across its 0°C to 70°C operating range. Exceeding these limits risks permanent damage.
Does the TLC2262CD support true rail-to-rail input?
No, the TLC2262CD features rail-to-rail *output* swing but not rail-to-rail *input*. Its common-mode input voltage range extends to the negative rail (VDD–/GND) but stops 1.5 V below the positive rail (VDD+ –1.5 V). This allows ground-sensing capability in single-supply systems but requires input signals to remain ≥1.5 V below VDD+ for linear operation.
Can the TLC2262CD drive capacitive loads directly?
The TLC2262CD is stable with up to 100 pF capacitive load when driving into 50 kΩ, as verified by phase margin (56°) and gain margin (11 dB) measurements. For larger capacitive loads (>100 pF), external isolation resistance (e.g., 10–50 Ω in series with output) is required to prevent peaking or oscillation-especially critical in ADC driver or filter applications.
How does the TLC2262CD compare to the TLC27M2 in terms of noise performance?
The TLC2262CD delivers 12 nV/√Hz input noise at 1 kHz-approximately 3× lower than the TLC27M2's typical 35 nV/√Hz. This improvement stems from Advanced LinCMOS™ process enhancements and optimized input transistor sizing, making the TLC2262CD significantly better suited for low-level signal amplification where noise dominates system resolution.
Is the TLC2262CD pin-compatible with other dual op-amps in SOIC-8 packages?
Yes, the TLC2262CD uses the industry-standard dual-opamp SOIC-8 pinout (Pin 1 = OUT1, Pin 2 = IN1–, Pin 3 = IN1+, Pin 4 = V–, Pin 5 = IN2+, Pin 6 = IN2–, Pin 7 = OUT2, Pin 8 = V+), matching TLC27M2, TLV2372, and LMV358. However, differences in input bias current, noise, and output swing require verification of signal chain performance when substituting.
