Product details
Overview
TLV2264QD from Texas Instruments is a quad rail-to-rail output operational amplifier optimized for low-voltage, low-power applications. It delivers 950 µV max input offset voltage, 12 nV/√Hz input voltage noise at 1 kHz, 500 µA max supply current per amplifier, and operates from 2.7 V to 8 V. It serves as a precision signal conditioner in automotive sensor interfaces and battery-powered data acquisition systems.
For engineers reviewing the TLV2264QD datasheet, TLV2264QD pinout, TLV2264QD application, or TLV2264QD equivalent, key selection criteria include its −40°C to 125°C automotive temperature rating, rail-to-rail output swing, low input bias current (1 pA typ), and compatibility with single-supply ADC driver topologies requiring wide common-mode input range down to the negative rail.
Technical Context
The TLV2264QD uses Advanced LinCMOS™ process technology to achieve high input impedance (>10¹² Ω) and low input bias current while maintaining rail-to-rail output capability. Its architecture supports both single-supply (2.7 V–8 V) and split-supply operation without performance degradation.
It features fully characterized AC performance at 3 V and 5 V, including 0.67 MHz gain-bandwidth product, 0.35–0.55 V/µs slew rate, and 55° phase margin with 100 pF capacitive load-enabling stable unity-gain buffer and active filter configurations in space-constrained automotive modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 8 V - enables direct integration into 3.3 V and 5 V automotive subsystems without level-shifting. |
| Input Offset Voltage (max) | 950 µV at TA = 25°C - ensures <1 LSB error when driving 12-bit SAR ADCs with 3.3 V reference. |
| Input Voltage Noise | 12 nV/√Hz at f = 1 kHz - critical for low-level piezoelectric transducer signal conditioning. |
| Supply Current (per amp) | 500 µA max - supports >10-year battery life in always-on vehicle health monitoring nodes. |
| Common-Mode Input Range | Includes negative rail (VDD−) - allows direct sensing of ground-referenced signals without biasing resistors. |
| Output Swing | Rail-to-rail - maximizes dynamic range into ADCs and preserves SNR across full supply range. |
| Operating Temperature | −40°C to 125°C - qualified for under-hood and powertrain control unit environments. |
Pinout & Package
TLV2264QD is housed in an 14-pin SOIC (D) package with standard quad op-amp pinout. The device features four independent amplifiers, dual supply pins (VDD+ and VDD−/GND), and no internal connections on pins 3, 5, 11, and 13 (NC).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Amplifier 1 Output | Drives low-impedance loads up to ±50 mA; rail-to-rail swing supports full-scale ADC input. |
| 2 | Amplifier 1 Inverting Input | High-impedance node (10¹² Ω); accepts signals down to VDD− without clipping. |
| 3 | No Connect | Internally unconnected; must be left floating or tied to GND per layout best practice. |
| 4 | Amplifier 1 Non-Inverting Input | High-Z input for sensor bridges or thermistor networks; minimal bias current avoids measurement error. |
| 5 | No Connect | Internally unconnected; no external connection required. |
| 6 | VDD− / GND | Power return for all four amplifiers; requires low-impedance local decoupling to minimize PSRR degradation. |
| 7 | Amplifier 2 Non-Inverting Input | Independent high-Z input; enables dual-channel sensor front-end with shared supply rails. |
| 8 | Amplifier 2 Inverting Input | Configurable for inverting gain stages or differential amplification with matched feedback networks. |
| 9 | No Connect | Internally unconnected; leave unpopulated on PCB. |
| 10 | Amplifier 2 Output | Provides second independent buffered output; identical AC/DC specs to Pin 1. |
| 11 | No Connect | Internally unconnected; no routing or termination needed. |
| 12 | VDD+ | Positive supply input; accepts 2.7–8 V; requires 0.1 µF ceramic decoupling adjacent to pin. |
| 13 | No Connect | Internally unconnected; no electrical function. |
| 14 | Amplifier 4 Output | Fourth independent output; supports multi-channel signal conditioning in compact ECUs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2264AQD | Same package and pinout; tighter 950 µV max VIO spec guaranteed over full temperature range (−40°C to 125°C). | Required for designs needing guaranteed offset performance across entire automotive operating range. | Select TLV2264AQD when production calibration is impractical and worst-case VIO must be bounded at temperature extremes. |
| LMV324QDR | Lower cost CMOS quad op-amp; higher 3 mV max VIO, 22 nV/√Hz noise, and only 1.8–5.5 V supply range. | Suitable for non-critical body electronics (e.g., mirror controls) where precision and extended voltage range are not required. | Choose LMV324QDR for cost-sensitive, non-safety-critical applications with 3.3 V supply and relaxed accuracy needs. |
Compared with TLV2264AQD, the TLV2264QD offers identical packaging and temperature rating but specifies VIO only at 25°C (950 µV max), making it appropriate for cost-optimized designs where room-temperature calibration is feasible. Versus LMV324QDR, TLV2264QD provides superior noise, offset, and supply flexibility-justifying its use in safety-relevant signal chains.

FAQ
What is the maximum input offset voltage specification for TLV2264QD?
The TLV2264QD has a maximum input offset voltage of 950 µV at TA = 25°C. This value is specified for the 'A' grade variant (TLV2264AQD) over the full −40°C to 125°C range, while TLV2264QD guarantees the 950 µV limit at 25°C per the SLOS186C datasheet. Designers should verify system-level offset budget accordingly when operating outside 25°C.
Does TLV2264QD support true rail-to-rail input operation?
No, TLV2264QD does not support rail-to-rail input common-mode range. Its common-mode input voltage range extends to the negative rail (VDD−) but stops 1.3 V below the positive rail (VDD+ − 1.3 V) at 3 V and 5 V supplies. This design enables robust operation with ground-referenced sensors while maintaining low input bias current and offset stability.
What is the supply current consumption of TLV2264QD per amplifier?
The TLV2264QD consumes a maximum of 500 µA per amplifier under recommended operating conditions (VDD = 2.7 V to 8 V, TA = −40°C to 125°C). Total quiescent current for all four amplifiers is thus ≤2 mA, enabling multi-channel signal conditioning in energy-constrained automotive modules without compromising battery runtime.
Is TLV2264QD qualified for automotive applications?
Yes, TLV2264QD is explicitly qualified for automotive use under Texas Instruments' Q-Temp program, meeting AEC-Q100 stress test requirements for Grade 2 (−40°C to +125°C ambient). It includes configuration control, print support, and qualification to automotive reliability standards-making it suitable for engine control, chassis, and ADAS subsystems.
Can TLV2264QD drive capacitive loads directly?
TLV2264QD is stable with up to 100 pF capacitive load at unity gain, as verified by 55° phase margin in the datasheet. For loads exceeding 100 pF, external isolation resistance (e.g., 10–100 Ω in series with the output) is recommended to maintain stability. This capability supports direct interfacing with ADC input capacitors and long PCB traces in distributed sensor networks.
