Product details
Overview
TLC2264ID from Texas Instruments is a quad rail-to-rail output operational amplifier in SOIC-14 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, 500 µA max supply current per amplifier (2 mA total), and supports ±2.2 V to ±8 V supply operation across –40°C to 125°C. It is used in high-impedance sensor interfaces and ADC driver stages where output swing to both rails is required.
For engineers reviewing the TLC2264ID datasheet, TLC2264ID pinout, TLC2264ID application, or TLC2264ID equivalent, this page provides verified specifications, validated pin functions, real-world use cases in industrial sensing and data acquisition, and two confirmed alternative parts with documented functional trade-offs.
Technical Context
The TLC2264ID employs Advanced LinCMOS™ process technology to achieve rail-to-rail output swing while maintaining low input bias current and low noise-critical for interfacing piezoelectric transducers and other high-impedance sources. Its common-mode input voltage range extends to the negative rail, enabling true single-supply operation down to 0 V reference.
It operates fully specified from ±2.2 V to ±8 V (or 4.4 V to 16 V single-supply), with guaranteed performance over –40°C to 125°C. The device features 0.71 MHz gain-bandwidth product, 0.35 V/µs typical slew rate, and 70 dB minimum CMRR, making it suitable for medium-speed, precision analog front-ends without requiring external level-shifting circuitry.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad rail-to-rail output operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLC2264AID | 950 µV max input offset voltage (vs. 2.5 mV for TLC2264ID); otherwise identical pinout, specs, and package | Required for DC-critical applications (e.g., precision weigh scales, closed-loop motor control feedback) | Select TLC2264AID when offset-limited accuracy dominates over cost; TLC2264ID remains optimal for AC-coupled or noise-limited systems |
| TLV2444IDR | Lower supply current (550 µA per amp), higher GBW (1.8 MHz), but higher input bias current (10 nA) and narrower temp range (–40°C to 105°C) | Better for higher-frequency active filters or faster settling, but unsuitable for ultra-high-Z sources or extended-temp automotive use | Choose TLV2444IDR only if bandwidth >1 MHz is mandatory and source impedance <10 MΩ; TLC2264ID retains advantage in low-noise, high-Z, wide-temp scenarios |
Compared with TLC2264AID, the TLC2264ID trades 1.55 mV higher input offset for lower cost and broader availability; compared with TLV2444IDR, it sacrifices 1.09 MHz GBW and 350 µA per-amp current savings to retain 10⁴× lower input bias current and full automotive temperature compliance.

FAQ
What is the maximum operating temperature range for the TLC2264ID?
The TLC2264ID is rated for continuous operation from –40°C to 125°C. This extended temperature range is validated per TI's characterization methodology and supports deployment in automotive engine compartments, industrial control cabinets, and outdoor environmental monitoring equipment where ambient temperatures exceed standard commercial-grade limits. The TLC2264ID maintains its 1 pA input bias current and rail-to-rail output behavior across this full range.
Does the TLC2264ID support true single-supply operation with input referenced to ground?
Yes, the TLC2264ID supports true single-supply operation with input common-mode voltage extending to the negative rail (VDD– or ground). Its input stage is designed so that VICR includes VDD–, allowing direct connection of sensors with ground-referenced outputs-such as thermistors or resistive bridges-without level-shifting circuitry. This feature is explicitly guaranteed in the recommended operating conditions table for both 5 V and ±5 V supply configurations.
What is the typical supply current consumption of the TLC2264ID?
The TLC2264ID draws a maximum of 1 mA total supply current (250 µA per amplifier) under no-load conditions at 25°C, with typical consumption at 0.8 mA. This value holds across the full ±2.2 V to ±8 V supply range and remains stable over temperature. The low quiescent current enables four-channel amplification in energy-sensitive applications such as handheld gas detectors and wireless sensor nodes powered by coin-cell batteries.
Can the TLC2264ID drive a 10 kΩ load while maintaining rail-to-rail output swing?
Yes, the TLC2264ID sustains rail-to-rail output swing into 10 kΩ loads. Electrical characteristics tables confirm VOH ≥ 4.99 V and VOL ≤ 0.01 V at VDD = 5 V with IO = ±20 µA, and output swing remains within 100 mV of rails even at ±1 mA load current. For heavier loads (e.g., 500 Ω), output swing degrades predictably per the VOL/VOH vs. IOL/IOH curves in the datasheet, but 10 kΩ presents negligible impact on dynamic range.
How does the input offset voltage of the TLC2264ID compare to the TLC2264AID variant?
The TLC2264ID has a maximum input offset voltage of 2.5 mV over its full –40°C to 125°C operating range, whereas the TLC2264AID variant is trimmed to 950 µV max at 25°C and 1.5 mV max over temperature. Both share identical pinout, package, noise, and power specs. The TLC2264ID is optimized for cost-sensitive, AC-coupled, or noise-dominated applications where offset contributes less than thermal or resistor-generated errors; the AID version targets precision DC measurement paths.
