Product details
Overview
TLC2264AIPWR from Texas Instruments is a quad rail-to-rail output operational amplifier in TSSOP-14 package, designed for precision signal conditioning in low-power, single- or split-supply systems. It delivers 950 µV max input offset voltage (TA = 25°C), 12 nV/√Hz input voltage noise at 1 kHz, 500 µA max supply current per amplifier, and rail-to-rail output swing - enabling direct interfacing with 5-V or ±5-V ADCs in battery-powered sensor front-ends.
For engineers reviewing the TLC2264AIPWR datasheet, TLC2264AIPWR pinout, TLC2264AIPWR application, or TLC2264AIPWR equivalent, key selection criteria include guaranteed low input bias current (1 pA typ), common-mode input range extending to negative rail, full characterization at both 5 V and ±5 V, and automotive-grade temperature support (–40°C to 125°C) for industrial monitoring and portable instrumentation.
Technical Context
The TLC2264AIPWR implements Advanced LinCMOS™ process technology to achieve high input impedance (>10¹² Ω), ultra-low input bias current (1 pA typ), and rail-to-rail output capability without compromising ac performance. Its architecture supports stable operation with capacitive loads up to 100 pF and maintains 56° phase margin at unity gain with 50 kΩ load and 100 pF capacitance.
It is fully specified for single-supply (VDD = 5 V) and split-supply (VDD± = ±5 V) operation, with common-mode input voltage range including the negative rail and output swing within 10 mV of both rails under light load. Input offset voltage is trimmed to ≤950 µV at 25°C, and supply current remains ≤1 mA total (250 µA per amplifier) across temperature.
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 total), wider GBW (1.8 MHz), but higher input offset (2 mV max) and noise (28 nV/√Hz) | Better for higher-speed filtering (>100 kHz), less suitable for ultra-low-power or ultra-low-noise dc sensing | Select TLV2444IDR only when bandwidth >1 MHz is required and power budget allows +40% current draw |
| OPA4340UA | Lower noise (8 nV/√Hz), lower VIO (120 µV max), but higher supply current (1.6 mA) and no AEC-Q100 option | Preferred for medical-grade precision where noise and offset dominate over temperature range or automotive qualification | Choose OPA4340UA for lab-grade instrumentation; avoid where extended temperature or automotive compliance is mandatory |
Compared with TLV2444IDR and OPA4340UA, the TLC2264AIPWR uniquely balances ultra-low input bias current (1 pA), rail-to-rail output, AEC-Q100 qualification, and sub-1-mA quiescent current - making it optimal for cost-sensitive, battery-operated, and automotive-qualified sensor systems requiring dc precision without speed overhead.

FAQ
What is the maximum operating temperature range for the TLC2264AIPWR?
The TLC2264AIPWR is rated for operation from –40°C to 125°C, meeting industrial and automotive environmental requirements. This range is validated per the I-suffix specification and confirmed in the Absolute Maximum Ratings and Recommended Operating Conditions tables of the official SLOS177D datasheet.
Does the TLC2264AIPWR support true single-supply operation with input signals referenced to ground?
Yes, the TLC2264AIPWR supports true single-supply operation: its common-mode input voltage range includes the negative rail (VDD–/GND), and the output swings rail-to-rail. This allows ground-referenced sensor inputs and direct interfacing with 0–5 V ADCs without level-shifting circuitry.
How does the input offset voltage of TLC2264AIPWR compare to the standard TLC2264IPWR?
The "A" suffix in TLC2264AIPWR denotes the precision grade: max input offset voltage is 950 µV at 25°C, versus 2.5 mV for the standard TLC2264IPWR. Both share identical pinout, package, and most electrical characteristics - the "A" variant is selected specifically for dc-critical applications.
Can the TLC2264AIPWR drive capacitive loads, and what is the stability limit?
The TLC2264AIPWR is stable with capacitive loads up to 100 pF when driving a 50 kΩ resistive load, as verified by 56° phase margin at unity gain in the datasheet. For loads >100 pF, external isolation resistance (e.g., 10–50 Ω in series with output) is recommended to maintain stability.
Is the TLC2264AIPWR pin-compatible with older TI op-amps like the TLC27L4 or TS27M4?
Yes - the TLC2264AIPWR shares the same TSSOP-14 pinout and footprint as TLC27L4IPW and TS27M4IPW, enabling drop-in replacement. It improves upon them with rail-to-rail output, lower noise (12 vs. 25 nV/√Hz), lower VIO (950 µV vs. 10 mV), and lower input bias current (1 pA vs. 100 pA).
