Product details
Overview
TLC2264CDR from Texas Instruments is a quad rail-to-rail output operational amplifier in SOIC-14 package, delivering 12 nV/√Hz input noise at 1 kHz, 500 µA max supply current per amplifier (2 mA total), and ±2.2 V to ±8 V dual-supply operation. It enables high-dynamic-range signal conditioning in battery-powered sensor interfaces and single-supply ADC drivers.
For engineers reviewing the TLC2264CDR datasheet, TLC2264CDR pinout, TLC2264CDR application, or TLC2264CDR equivalent, this page provides verified electrical specs, validated SOIC-14 terminal mapping, real-world use cases in precision analog front-ends, and two confirmed alternative op-amps with documented performance trade-offs.
Technical Context
The TLC2264CDR implements Advanced LinCMOS™ process technology to achieve rail-to-rail output swing while maintaining low input bias current (1 pA typ) and low noise-critical for high-impedance source interfacing like piezoelectric transducers. Its common-mode input range includes the negative rail, supporting true single-supply operation down to 0 V ground reference.
It features fully specified performance across 0°C to 70°C ambient, with 950 µV max input offset voltage for the 'A' grade (not applicable here), while the 'C' grade (TLC2264CDR) specifies 2.5 mV max. The device exhibits 0.71 MHz gain-bandwidth product and 0.35 V/µs min slew rate under 5 V single-supply conditions.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad rail-to-rail operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2444CDR | Higher supply current (1.4 mA total), 0.65 V/µs slew rate, 22 nV/√Hz noise - optimized for higher-speed, lower-precision uses | Preferred where faster settling (<3 µs) is needed but sub-µV noise not required - e.g., motor control feedback | Select TLV2444CDR when bandwidth >1 MHz is mandatory and power budget allows +40% current draw |
| OPA2340UA/2K5 | Lower noise (8 nV/√Hz), higher precision (125 µV max Vos), but only dual-channel - requires two packages for quad function | Better suited for metrology-grade instrumentation where channel count is secondary to absolute accuracy | Choose OPA2340UA/2K5 only if Vos <200 µV and noise <10 nV/√Hz are mandatory, accepting doubled PCB area and cost |
Compared with TLV2444CDR and OPA2340UA/2K5, the TLC2264CDR delivers optimal balance of ultra-low input bias current, moderate speed, and quad integration - making it the preferred choice for space-constrained, battery-operated sensor systems requiring high-Z compatibility and rail-to-rail output fidelity.

FAQ
What is the maximum supply voltage rating for the TLC2264CDR?
The TLC2264CDR has an absolute maximum supply voltage rating of ±8 V for dual-supply operation or 16 V for single-supply use. Operation beyond these limits risks permanent damage. Recommended operating range is ±2.2 V to ±8 V or 4.4 V to 16 V, with full electrical specifications guaranteed across that span for the TLC2264CDR.
Does the TLC2264CDR support true single-supply operation with input signals down to ground?
Yes, the TLC2264CDR supports true single-supply operation with its common-mode input voltage range extending to the negative rail (VDD– or ground). This allows direct interfacing with sensors referenced to ground - such as thermistors or bridge circuits - without level-shifting circuitry, preserving accuracy and reducing component count in the TLC2264CDR-based design.
What is the typical input offset voltage specification for the TLC2264CDR?
The TLC2264CDR has a maximum input offset voltage of 2.5 mV at 25°C, with typical value of 300 µV. This specification applies across the full 0°C to 70°C operating temperature range. For applications requiring tighter offset control, the pin-compatible TLC2264ACDR variant offers 950 µV max, but the standard TLC2264CDR remains optimal for cost-sensitive, general-purpose analog conditioning.
Can the TLC2264CDR drive capacitive loads directly, and what is its phase margin?
The TLC2264CDR is characterized with 100 pF capacitive load and 50 kΩ resistive load, achieving 56° phase margin at unity gain - ensuring stable operation without external compensation in most sensor buffer and filter applications. While it can drive moderate capacitive loads directly, sustained >1 nF loads may require isolation resistance or feedback compensation to maintain stability in the TLC2264CDR circuit.
Is the TLC2264CDR RoHS compliant and halogen-free?
Yes, the TLC2264CDR is RoHS compliant and halogen-free per Texas Instruments' published environmental compliance documentation. The SOIC-14 (D) package uses lead-free terminations and meets JEDEC J-STD-020 moisture sensitivity level 3 requirements, supporting standard reflow profiles without special handling for the TLC2264CDR in automated assembly.
