Product details
Overview
TLC2264IDR from Texas Instruments is a quad rail-to-rail output operational amplifier in an SOIC-14 package, designed for precision signal conditioning in single- or split-supply systems. It delivers 12 nV/√Hz input voltage noise at 1 kHz, 1 pA typical input bias current, and 500 µA maximum supply current per amplifier (2 mA total), enabling low-power, high-impedance sensor interfacing in industrial and automotive applications.
For engineers reviewing the TLC2264IDR datasheet, TLC2264IDR pinout, TLC2264IDR application, or TLC2264IDR equivalent, key selection criteria include its –40°C to 125°C operating range, rail-to-rail output swing, low offset voltage (≤2.5 mV max), and compatibility with ADC driver and piezoelectric transducer front-end designs.
Technical Context
The TLC2264IDR uses Advanced LinCMOS™ process technology to achieve rail-to-rail output swing while maintaining CMOS-level input impedance (>10¹² Ω) and ultra-low input bias current (1 pA typ). Its common-mode input voltage range extends to the negative rail, supporting true single-supply operation down to 4.4 V total supply.
It features a gain-bandwidth product of 0.71 MHz (VDD = 5 V), slew rate of 0.35–0.55 V/µs, and phase margin of 56°, ensuring stable unity-gain operation with capacitive loads up to 100 pF. The device is fully characterized across –40°C to 125°C and qualified for automotive-grade reliability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | ±2.2 V to ±8 V (or 4.4 V to 16 V single-supply) - supports wide-input industrial and automotive rails. |
| Input Bias Current | 1 pA typical - enables high-impedance source interfacing (e.g., pH sensors, piezoelectrics) without loading error. |
| Input Offset Voltage | ≤2.5 mV max at TA = 25°C - ensures DC accuracy in precision amplification and sensor offset correction. |
| Output Swing | Rail-to-rail - delivers full dynamic range into ADCs (e.g., 0–5 V input span) without headroom loss. |
| Supply Current (total) | 1 mA max (250 µA per amp) - enables battery-powered portable instrumentation and remote sensing. |
| Input Voltage Noise | 12 nV/√Hz at 1 kHz - improves SNR in low-level analog signal chains (e.g., medical ECG front-ends). |
| Operating Temperature | –40°C to 125°C - certified for under-hood automotive and industrial control environments. |
Pinout & Package
Package: SOIC-14 (D package), surface-mount, tape-and-reel (R suffix indicates reel packaging).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 9, 13 | Inverting Input (–IN) | High-impedance differential input for each of four op-amps; accepts signals down to VDD–. |
| 2, 6, 10, 14 | Non-inverting Input (+IN) | Common-mode range includes negative rail - enables true single-supply sensor biasing. |
| 3, 7, 11, 12 | Output | Rail-to-rail output stage drives loads to within ~100 mV of either supply rail. |
| 4 | VDD– / GND | Negative supply or ground reference; common return for all four amplifiers. |

Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output | Swings within 100 mV of both supply rails - maximizes usable ADC input range and dynamic headroom. |
| Low input bias current | 1 pA typical - eliminates significant error in high-Z feedback networks (e.g., >10 MΩ gain-setting resistors). |
| Low-noise performance | 12 nV/√Hz at 1 kHz - preserves signal integrity in microphone preamps and strain-gauge bridges. |
| Wide temperature range | –40°C to 125°C operation - meets AEC-Q100 Grade 2 requirements for automotive powertrain modules. |
| Split- and single-supply support | Fully specified for ±5 V and +5 V operation - simplifies design reuse across legacy and new architectures. |

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 slew rate (1.5 V/µs), higher supply current (1.2 mA total), lower VIO (1.6 mV max), same SOIC-14 package. | Better suited for higher-frequency active filters or faster-settling data acquisition paths. | Select TLV2444IDR when bandwidth >1 MHz and settling time <3 µs are required; verify thermal dissipation at 125°C. |
| OPA4340UA | Lower noise (8 nV/√Hz), lower VIO (1.5 mV max), higher cost, SOIC-14, but only rated to 85°C (not automotive). | Preferred for lab-grade instrumentation where noise dominates, but not for under-hood automotive use. | Choose OPA4340UA for metrology-grade precision at ambient temperatures; avoid in extended-temperature automotive or industrial deployments. |
Compared with TLV2444IDR and OPA4340UA, the TLC2264IDR provides optimal balance of low power (1 mA), rail-to-rail output, and extended temperature capability (–40°C to 125°C) - making it uniquely suitable for cost-sensitive, thermally demanding embedded systems where moderate bandwidth suffices.

FAQ
What is the maximum supply voltage for TLC2264IDR?
The TLC2264IDR supports a maximum total supply voltage of 16 V in single-supply mode or ±8 V in split-supply mode. Absolute maximum ratings specify VDD+ ≤ 8 V and VDD– ≥ –8 V. Exceeding these limits risks permanent damage. Operation above ±8 V or below ±2.2 V is outside recommended conditions and may degrade performance or reliability.
Does TLC2264IDR support true single-supply operation with input signals near ground?
Yes, the TLC2264IDR supports true single-supply operation: its common-mode input voltage range includes the negative rail (VDD–/GND), and the input can accept signals down to VDD–. This allows direct interfacing with grounded sensors or DAC outputs without level-shifting circuitry - confirmed in the datasheet's VICR specification (0 V to VDD–1.5 V at full range).
What is the typical input offset voltage for TLC2264IDR at room temperature?
The typical input offset voltage for TLC2264IDR at TA = 25°C is 300 µV, with a maximum of 2.5 mV across the full operating temperature range (–40°C to 125°C). This value is explicitly specified in the "TLC2264I electrical characteristics" table on page 14 of the SLOS177D datasheet.
Can TLC2264IDR drive capacitive loads directly?
The TLC2264IDR is stable with capacitive loads up to 100 pF when configured for unity-gain operation, as verified by phase margin (56°) and gain margin (11 dB) measurements in the datasheet. For loads >100 pF, external isolation resistance (e.g., 10–100 Ω in series with the output) is recommended to maintain stability and prevent peaking or oscillation.
Is TLC2264IDR qualified for automotive applications?
Yes, the 'I' temperature grade in TLC2264IDR denotes –40°C to 125°C operation and qualifies the device for automotive applications. Texas Instruments documents this part as suitable for Q-Temp Automotive HighRel applications, including qualification to AEC-Q100 stress test standards - confirmed in the device family introduction and packaging tables of the SLOS177D datasheet.
