Product details
Overview
TLC2264AIDR 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 950 µV max input offset voltage at 25°C, 12 nV/√Hz input voltage noise at 1 kHz, 500 µA max supply current per amplifier (2 mA total), and rail-to-rail output swing - enabling full dynamic range utilization when interfacing with 12-bit ADCs in battery-powered sensor front-ends.
For engineers reviewing the TLC2264AIDR datasheet, TLC2264AIDR pinout, TLC2264AIDR application, or TLC2264AIDR equivalent, key selection criteria include its guaranteed low VIO over –40°C to 125°C, CMOS input bias current ≤1 pA, and compatibility with 2.2 V to ±8 V supplies - critical for high-impedance transducer amplification, portable medical monitors, and industrial analog I/O modules.
Technical Context
The TLC2264AIDR implements Advanced LinCMOS™ process technology to achieve rail-to-rail output swing while maintaining ultra-low input bias current (1 pA typ) and low noise (12 nV/√Hz). Its input stage operates with common-mode voltage extending to the negative rail, supporting true single-supply operation down to 2.2 V.
Each of the four independent amplifiers features fully characterized performance across –40°C to 125°C, with guaranteed 950 µV max VIO and 0.35 V/µs min slew rate at unity gain. The device is specified for both single-supply (VDD = 4.4 V to 16 V) and split-supply (±2.2 V to ±8 V) configurations without performance degradation.
Key Specifications

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 |
|---|---|---|---|
| TLV2444IDR | Higher supply current (1.4 mA), lower VIO (1.5 mV max), no A-grade option; 1.2 V/µs slew rate. | Better AC performance but higher power; not qualified for extended temperature range. | Select TLV2444IDR only if bandwidth >1 MHz is required and temperature range is limited to 0°C–70°C. |
| OPA4340UA | Lower noise (8 nV/√Hz), lower VIO (125 µV max), but higher supply current (750 µA per amp); SOIC-14. | Superior precision at cost of 50% higher quiescent power; requires tighter layout for noise immunity. | Choose OPA4340UA when sub-200 µV offset and <10 nV/√Hz noise are mandatory, and power budget allows ≥3 mA total. |
Compared with TLV2444IDR and OPA4340UA, the TLC2264AIDR provides the optimal balance of ultra-low input bias current (1 pA), guaranteed 950 µV VIO over –40°C to 125°C, and 1 mA total supply current - making it uniquely suited for high-impedance, wide-temperature, battery-constrained applications where precision and power coexist.

FAQ
What is the maximum operating temperature range for the TLC2264AIDR?
The TLC2264AIDR is rated for continuous operation from –40°C to +125°C, with all electrical specifications guaranteed across this full industrial temperature range. This makes the TLC2264AIDR suitable for under-hood automotive applications and harsh-environment industrial controls where thermal stability is critical.
Does the TLC2264AIDR support true single-supply operation with input signals referenced to ground?
Yes, the TLC2264AIDR supports true single-supply operation: its common-mode input voltage range includes the negative rail (VDD–/GND), and its output swings rail-to-rail. When powered from a single 5 V supply with VDD– tied to ground, the TLC2264AIDR accepts inputs from 0 V and delivers outputs from near 0 V to near 5 V - eliminating the need for level-shifting circuitry.
How does the input offset voltage specification of the TLC2264AIDR compare to the standard TLC2264IDR?
The "A" suffix in TLC2264AIDR denotes the precision grade: it guarantees ≤950 µV maximum input offset voltage at 25°C, whereas the standard TLC2264IDR is specified at ≤2.5 mV max. Both share identical pinout, package, and temperature range, but the A-grade version reduces DC error by more than 2× - critical for uncalibrated precision measurement paths.
Can the TLC2264AIDR drive capacitive loads directly, and what is its phase margin?
The TLC2264AIDR is stable with capacitive loads up to 100 pF when configured with unity-gain feedback and a 50 kΩ load. Its phase margin is 56° at unity gain (VDD = 5 V), ensuring robust step response without peaking or oscillation. For loads >100 pF, an isolation resistor (e.g., 10–50 Ω) in series with the output is recommended to maintain stability.
Is the TLC2264AIDR pin-compatible with legacy TI op-amps like the TLC27M4 or TS27M4?
Yes, the TLC2264AIDR uses the same SOIC-14 pinout as the TLC27M4 and TS27M4, enabling drop-in replacement in existing designs. It improves upon those predecessors with rail-to-rail output swing, lower input offset voltage (950 µV vs. 5 mV), lower noise (12 nV/√Hz vs. 25 nV/√Hz), and lower input bias current (1 pA vs. 10 pA), delivering immediate performance uplift without PCB changes.
