Product details
Overview
TLC2264AINE4 from Texas Instruments is a quad rail-to-rail output operational amplifier in a 14-pin plastic DIP (N) package, specified for industrial temperature range (–40°C to 125°C), with maximum input offset voltage of 950 µV at 25°C, low input bias current (1 pA typ), and supply current of 1 mA (four amplifiers, VDD = 5 V). It enables high-precision signal conditioning in single-supply sensor interfaces and battery-powered data acquisition systems.
For engineers reviewing the TLC2264AINE4 datasheet, TLC2264AINE4 pinout, TLC2264AINE4 application, or TLC2264AINE4 equivalent, key selection criteria include rail-to-rail output swing, 12 nV/√Hz input noise at 1 kHz, ±5 V or single 5 V operation, and compatibility with ADC driver stages requiring low VIO and wide common-mode input range extending to the negative rail.
Technical Context
The TLC2264AINE4 implements Advanced LinCMOS™ process technology to achieve rail-to-rail output swing while maintaining CMOS-level input bias current (1 pA typ) and low noise (12 nV/√Hz at 1 kHz). Its input stage accepts common-mode voltages down to the negative supply rail, supporting true single-supply operation without level-shifting circuitry.
It delivers 0.35–0.55 V/µs slew rate and 0.71 MHz gain-bandwidth product under 5 V supply, with 70–83 dB CMRR and 80–95 dB PSRR - optimized for precision DC-coupled amplification and low-frequency AC signal conditioning where micropower and accuracy coexist.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | ±2.2 V to ±8 V or single 4.4 V to 16 V - supports dual-supply lab instrumentation and single-supply portable systems. |
| Input Offset Voltage (max) | 950 µV at TA = 25°C - enables <1 LSB error in 12-bit ADC front-ends with gain ≤10. |
| Input Bias Current (typ) | 1 pA - preserves signal integrity from high-impedance sources like piezoelectric sensors or pH electrodes. |
| Output Swing | Rail-to-rail - delivers full dynamic range into ADCs or low-voltage logic without external level-shifting. |
| Supply Current (4 amps) | 1 mA max at 5 V - allows four independent channels in space-constrained, battery-operated devices. |
| Input Noise Voltage | 12 nV/√Hz at 1 kHz - improves SNR in audio preamps and sensor signal chains over prior TLC27M4 generation. |
| Common-Mode Input Range | Includes negative rail (VDD–) - eliminates need for biasing resistors in single-supply transducer interfaces. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLC2264IN | Same package and pinout; higher max VIO (2.5 mV vs. 950 µV) and wider temp range (0°C to 70°C). | Acceptable for non-critical industrial controls but not precision sensor front-ends requiring <1 mV offset. | Select TLC2264IN only when cost sensitivity outweighs VIO requirement and ambient temperature stays within 0–70°C. |
| TLV2444CDR | Lower supply current (550 µA vs. 1 mA), higher GBW (1.8 MHz), but VIO max = 2.5 mV and no A-grade option. | Better for high-speed, low-power applications (e.g., active filters >100 kHz); unsuitable for DC-critical offset budgets. | Choose TLV2444CDR when bandwidth >1 MHz is needed and VIO tolerance ≥2.5 mV is acceptable. |
Compared with TLC2264IN and TLV2444CDR, the TLC2264AINE4 uniquely combines industrial temperature rating, 950 µV VIO guarantee, and rail-to-rail output in a through-hole DIP - making it the only drop-in solution for legacy-replacement precision analog designs requiring long-term stability and zero-layout change.

FAQ
What is the maximum operating temperature range for the TLC2264AINE4?
The TLC2264AINE4 is rated for industrial operation from –40°C to +125°C. This specification is validated across all electrical parameters in the datasheet, including input offset voltage, CMRR, and output swing. The 'I' suffix explicitly denotes this extended temperature grade, distinguishing it from commercial-grade variants like TLC2264CN.
Does the TLC2264AINE4 support true single-supply operation with input signals referenced to ground?
Yes. The TLC2264AINE4 features a common-mode input voltage range that includes the negative supply rail (VDD–), which is typically grounded in single-supply configurations. This allows direct connection of ground-referenced transducers - such as thermistors or bridge sensors - without external biasing networks or level-shifting circuitry.
What is the typical input noise voltage of the TLC2264AINE4, and at what frequency is it specified?
The TLC2264AINE4 has a typical equivalent input noise voltage of 12 nV/√Hz at 1 kHz, and 40–43 nV/√Hz at 10 Hz. These values are measured under standard conditions (VDD = 5 V, TA = 25°C) and reflect its suitability for low-frequency precision applications like strain gauge or thermocouple amplification where 1/f noise dominates.
Can the TLC2264AINE4 drive ADC inputs directly, and what output swing capability does it provide?
Yes. The TLC2264AINE4 provides rail-to-rail output swing - delivering output voltages within ~10 mV of both supply rails under light load. At VDD = 5 V, VOH ≥ 4.99 V and VOL ≤ 0.01 V (IO = ±20 µA), enabling direct interface with 12- to 16-bit SAR and delta-sigma ADCs without external level-shifting or gain adjustment.
How does the TLC2264AINE4 differ from the standard TLC2264IN in terms of precision specifications?
The TLC2264AINE4 is the 'A' grade variant, guaranteeing a maximum input offset voltage of 950 µV at 25°C, whereas the TLC2264IN specifies 2.5 mV max. Both share the same DIP-14 package and industrial temperature range, but the 'A' grade undergoes tighter post-package trimming and screening - critical for applications requiring minimal calibration or high DC accuracy.
