Product details
Overview
TLC2264CD from Texas Instruments is a quad 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 low-noise, micropower operation in battery-powered sensor interfaces and ADC driver stages.
For engineers reviewing the TLC2264CD datasheet, TLC2264CD pinout, TLC2264CD application, or TLC2264CD equivalent, key selection criteria include its rail-to-rail output swing (±4.8 V at ±5 V supplies), 0.71 MHz gain-bandwidth product, 0.35 V/µs slew rate, 70 dB minimum CMRR, and guaranteed operation from 0°C to 70°C - all critical for analog front-end design in industrial monitoring and portable instrumentation.
Technical Context
The TLC2264CD uses Advanced LinCMOS™ process technology to achieve rail-to-rail output swing while maintaining low input bias current (1 pA typ) and low noise (12 nV/√Hz). Its input stage includes common-mode voltage range extending to the negative rail, supporting true single-supply operation down to 4.4 V total supply.
Each of the four amplifiers features fully specified performance across 0°C to 70°C, with 2.5 mV max input offset voltage at 25°C and 2 µV/°C temperature coefficient. The device is characterized for both 5 V single-supply and ±5 V split-supply configurations, with output drive capability up to ±50 mA.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | ±2.2 V to ±8 V (split) or 4.4 V to 16 V (single) - supports wide-input industrial and automotive power rails |
| Input Offset Voltage | 300–2500 µV max at 25°C - enables DC-coupled precision amplification without external trimming |
| Input Bias Current | 1 pA typical - preserves signal integrity in high-impedance sensor circuits (e.g., piezoelectric transducers) |
| Output Swing | Within 100 mV of both rails at ±5 V - maximizes dynamic range when driving 12-bit+ ADCs |
| Gain-Bandwidth Product | 0.71 MHz - sufficient for anti-aliasing filters and low-frequency sensor signal conditioning |
| Slew Rate | 0.35 V/µs - adequate for <10 kHz bandwidth applications with minimal distortion |
| Common-Mode Rejection | 70 dB min - ensures stable operation in noisy industrial environments with ground offsets |
Pinout & Package
Package: 8-pin SOIC (D), surface-mount, tape-and-reel compatible (TLC2264CDR variant available).
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting input (Amplifier A) | Accepts differential signal reference; high-impedance node requiring guarded layout |
| 2 | Non-inverting input (Amplifier A) | High-Z input for sensor or reference connection; common-mode range includes negative rail |
| 3 | Output (Amplifier A) | Rail-to-rail output capable of sourcing/sinking ±50 mA - drives ADC inputs directly |
| 4 | Ground / VDD− | Return path for all four amplifiers; must be low-impedance to minimize PSRR degradation |
| 5 | VDD+ | Positive supply pin; decoupling capacitor required within 1 cm for stability |
| 6 | Output (Amplifier B) | Independent rail-to-rail output; no internal crosstalk with Amplifier A under load |
| 7 | Inverting input (Amplifier B) | Second high-Z input channel; identical electrical specs to Pin 1 |
| 8 | Non-inverting input (Amplifier B) | Second sensor/reference input; shares same common-mode and offset specs as Pin 2 |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output | Delivers full supply-voltage swing (e.g., 0–4.9 V on 5 V rail), eliminating level-shifting circuitry before ADCs |
| Low input bias current | 1 pA typical enables use with >1 GΩ source impedances (e.g., pH electrodes, photodiode TIA feedback) |
| Low noise performance | 12 nV/√Hz at 1 kHz allows clean amplification of µV-level signals without dominant noise contribution |
| Single- and split-supply support | Fully characterized at 5 V and ±5 V - simplifies migration between portable (single) and test equipment (split) designs |
| Micro-power operation | 1 mA max total supply current (four amps) extends battery life in handheld data loggers and remote sensors |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLC2264CPW | TSSOP-14 package (14-pin), same electrical specs, higher pin count accommodates separate power/ground pins per amplifier pair | Better thermal performance and lower crosstalk in high-density PCB layouts; requires different footprint | Select when board space is constrained but thermal management or channel isolation is critical |
| TLV2434CD | Higher slew rate (1.5 V/µs), lower supply current (550 µA total), but only 500 kHz GBW and 25 µV/°C offset drift | Superior for fast-settling multiplexed ADC drivers; less suitable for precision DC-coupled applications | Select when speed dominates over DC accuracy - e.g., multichannel data acquisition with >10 kSPS throughput |
Compared with TLC2264CPW, the TLC2264CD offers identical analog performance in a smaller SOIC-8 footprint but lacks dedicated power pins per amplifier pair; compared with TLV2434CD, it trades bandwidth and speed for superior DC precision and lower noise - making it optimal for sensor signal chains where accuracy outweighs speed.

FAQ
What is the maximum operating temperature range for the TLC2264CD?
The TLC2264CD is rated for operation from 0°C to 70°C ambient temperature. This commercial-grade temperature range is defined in the recommended operating conditions table of the official datasheet (SLOS177D), and applies specifically to the 'C' suffix variant. For extended temperature operation, consider the TLC2264ID (–40°C to 125°C) or TLC2264AID (950 µV max VIO, –40°C to 125°C).
Does the TLC2264CD support true single-supply operation with input voltage down to ground?
Yes, the TLC2264CD supports true single-supply operation with its common-mode input voltage range extending to VDD– (ground), as confirmed in the "Recommended Operating Conditions" table. At 5 V supply, the input common-mode range is specified from 0 V to 3.5 V, allowing direct interfacing with ground-referenced sensors without level-shifting circuitry - a key feature enabled by its Advanced LinCMOS™ input stage.
What is the typical supply current consumption of the TLC2264CD?
The TLC2264CD draws 0.8–1.0 mA total supply current (for all four amplifiers) at 25°C with no load, as specified in the "Electrical Characteristics" tables for VDD = 5 V and VDD± = ±5 V. This value is well within the 1 mA maximum limit stated in the datasheet, making it suitable for low-power applications such as battery-powered data loggers and portable instrumentation where quiescent current directly impacts runtime.
Can the TLC2264CD drive a standard 10-bit or 12-bit SAR ADC directly?
Yes, the TLC2264CD can directly drive most 10-bit and 12-bit SAR ADCs. Its rail-to-rail output swing (e.g., 0–4.99 V on 5 V supply), low output impedance (<250 Ω), and 0.35 V/µs slew rate ensure settling within typical ADC acquisition windows. The 0.71 MHz gain-bandwidth product provides adequate phase margin for unity-gain stable operation into typical ADC input capacitance (≤20 pF), as verified in the "Operating Characteristics" section.
Is the TLC2264CD pin-compatible with older TI op-amps like the TLC27M4?
No, the TLC2264CD is not pin-compatible with the TLC27M4. While both are quad SOIC-14 op-amps, the TLC2264CD uses an 8-pin SOIC (D) package - a fundamentally different pinout and footprint. The TLC2264CD's 8-pin configuration consolidates power and ground pins (Pins 4 and 5), whereas the TLC27M4 uses 14 pins with separate VDD+/VDD– and individual amplifier I/O. Migration requires PCB redesign, though the TLC2264CD offers improved noise, rail-to-rail output, and lower bias current.
