Product details
Overview
TLV2264IDR from Texas Instruments is a quad rail-to-rail output operational amplifier optimized for low-voltage, low-power applications. 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 across 2.7 V to 8 V operation. Its common-mode input range includes the negative rail and supports single-supply interfacing with precision ADCs in battery-powered sensor signal conditioning.
For engineers reviewing the TLV2264IDR datasheet, TLV2264IDR pinout, TLV2264IDR application, or TLV2264IDR equivalent, key selection criteria include guaranteed 950 µV max input offset voltage (A-grade), rail-to-rail output swing, −40°C to 125°C automotive temperature rating, and SOIC-14 package compatibility with legacy TLV2334 layouts.
Technical Context
This CMOS-based op-amp family bridges micro-power and AC performance: it improves upon TLV225x power efficiency while offering better noise and bandwidth than TLC227x. The architecture enables stable unity-gain operation with 55° phase margin and supports capacitive loads up to 100 pF without oscillation.
It is fully characterized at 3 V and 5 V, with rail-to-rail output stage delivering >2.65 V high-level and <300 mV low-level output voltage into 1 mA load at 3 V supply - enabling full dynamic range utilization in single-supply data acquisition systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 8 V - operates from single-cell Li-ion (3.0 V) or dual alkaline (3.0 V) without regulation. |
| Input Offset Voltage (max) | 950 µV at TA = 25°C - ensures ≤0.02% gain error in 12-bit ±2.5 V input ranges. |
| Input Bias Current (typ) | 1 pA - preserves signal integrity from high-impedance sources like piezoelectric sensors. |
| Supply Current (per amp) | 500 µA max - enables four-channel amplification at <2 mA total, ideal for portable instrumentation. |
| Input Voltage Noise | 12 nV/√Hz at 1 kHz - 3× lower than predecessor TLV2334, critical for low-level transducer signals. |
| Gain-Bandwidth Product | 0.67 MHz at 3 V - sufficient for anti-aliasing filters and sensor front-end buffering up to ~100 kHz. |
| Output Swing (RL=10 kΩ) | Within 175 mV of rails at 3 V - delivers >2.65 Vpp output for 3 V ADC reference compatibility. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2334IDR | Higher input offset (3 mV max), higher supply current (1.2 mA/amp), no A-grade option. | Lacks guaranteed low-VIO for precision DC-coupled measurement; suitable only for AC-coupled or less demanding DC paths. | Select TLV2264IDR when VIO ≤950 µV and supply current <1 mA per amp are required. |
| TLV9054IDR | Lower noise (7 nV/√Hz), higher GBW (5 MHz), but 1.2 mA/amp supply current and narrower supply range (1.8–5.5 V). | Not viable for 8 V systems or ultra-low-power designs; superior for high-speed sensor readout where power budget allows. | Choose TLV2264IDR for 2.7–8 V operation and sub-1 mA/amp consumption; TLV9054IDR only if bandwidth >1 MHz is mandatory. |
Compared with TLV2334IDR and TLV9054IDR, TLV2264IDR uniquely balances ultra-low input bias current, guaranteed low offset, wide supply range, and sub-1 mA quiescent current - making it the optimal choice for precision, low-power, multi-channel analog front-ends in automotive and industrial edge nodes.

FAQ
What is the operating temperature range for TLV2264IDR?
The TLV2264IDR is rated for −40°C to 125°C operation, meeting automotive under-hood and industrial control requirements. This specification is validated per AEC-Q100 stress testing and applies across the full 2.7 V to 8 V supply range. The device maintains specified input offset voltage, noise, and output drive capability throughout this range, making TLV2264IDR suitable for harsh-environment deployments without thermal derating.
Does TLV2264IDR support true rail-to-rail input?
No, TLV2264IDR features rail-to-rail *output* but not rail-to-rail *input*. Its common-mode input voltage range extends to the negative rail (VDD−) but stops 1.3 V below the positive rail (VDD+) at 3 V supply - i.e., 0 V to 1.7 V. This design enables robust operation with ground-referenced sensors while maintaining CMOS input stage integrity; TLV2264IDR does not accept inputs at VDD+.
How does the input offset voltage of TLV2264IDR compare to TLV2264CDR?
TLV2264IDR is the "I" grade with 950 µV maximum input offset voltage at 25°C, whereas TLV2264CDR (commercial grade) has 2.5 mV maximum. The "I" suffix denotes enhanced initial accuracy and tighter temperature drift (2 µV/°C), making TLV2264IDR appropriate for precision DC-coupled applications like medical instrumentation or calibrated sensor interfaces where offset-induced errors must remain below 0.02% of full scale.
Can TLV2264IDR drive capacitive loads directly?
Yes, TLV2264IDR is stable with up to 100 pF capacitive load when configured for unity gain, as verified by 55° phase margin and 11 dB gain margin in the datasheet. For loads >100 pF, a series isolation resistor (e.g., 10–50 Ω) between output and capacitor is recommended to maintain stability. This capability simplifies anti-aliasing filter design and direct connection to ADC input capacitance without external compensation.
Is TLV2264IDR pin-compatible with TLV2334IDR?
Yes, TLV2264IDR and TLV2334IDR share identical SOIC-14 pinouts and footprint, enabling drop-in replacement in existing designs. However, TLV2264IDR offers lower input offset (950 µV vs. 3 mV), lower noise (12 nV/√Hz vs. 25 nV/√Hz), and lower supply current (500 µA vs. 1.2 mA per amp), so layout changes are unnecessary but performance improvements require verification of loop stability and signal chain gain calibration.
