Product details
Overview
TLV2264AIPWR 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 is used in precision signal conditioning of high-impedance sources such as piezoelectric transducers and in battery-powered remote sensing.
For engineers reviewing the TLV2264AIPWR datasheet, TLV2264AIPWR pinout, TLV2264AIPWR application, or TLV2264AIPWR equivalent, key selection considerations include its guaranteed 950 µV VIO over −40°C to 125°C, rail-to-rail output swing with single-supply operation, and compatibility with analog-to-digital converter (ADC) interface circuits requiring wide dynamic range.
Technical Context
The TLV2264AIPWR implements a CMOS-input, rail-to-rail output architecture with fully differential input stage and push-pull output stage. Its design supports stable unity-gain operation with 55° phase margin and 11 dB gain margin when driving 100 pF capacitive loads with 50 kΩ resistive load.
It features high input impedance (>10¹² Ω), low input bias current (1 pA typ), and common-mode input voltage range extending to the negative rail - enabling direct interfacing with ground-referenced sensors and single-supply data acquisition systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 8 V - enables operation from single Li-ion cell (3.0–3.7 V) up to dual AA/AAA (3.0 V) or regulated 5 V rails. |
| Input Offset Voltage (max) | 950 µV at TA = 25°C - ensures ≤0.05% gain error in 10-bit ADC front-end with 3 V full-scale reference. |
| Supply Current (per amp) | 500 µA max - allows four-channel operation at <2 mA total, suitable for always-on sensor nodes. |
| Input Voltage Noise | 12 nV/√Hz at f = 1 kHz - supports low-noise amplification of microvolt-level signals from piezo or strain gauges. |
| Output Swing | Rail-to-rail - delivers >99% of supply voltage swing, maximizing ADC utilization without level-shifting circuitry. |
| Gain-Bandwidth Product | 0.67 MHz at VDD = 3 V - sufficient for anti-aliasing filters and sensor signal conditioning up to ~100 kHz. |
| Common-Mode Input Range | Includes negative rail (VDD−) - permits direct connection of ground-referenced transducer outputs without biasing networks. |
Pinout & Package
TSSOP-14 package (PW), 4.4 mm × 5.0 mm body, 0.65 mm pitch, exposed pad optional (not electrically connected).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives external load or next-stage input; rail-to-rail capable. |
| 2 | IN− A | Inverting input of Amp A - high-impedance node; sensitive to PCB leakage and guarding requirements. |
| 3 | IN+ A | Non-inverting input of Amp A - accepts DC-coupled sensor signals referenced to VDD−. |
| 4 | VDD− / GND | Power ground / negative supply - shared return path for all four amplifiers; requires low-impedance local decoupling. |
| 5 | IN+ B | Non-inverting input of Amp B - independent channel; supports differential pair configuration with IN− B (Pin 6). |
| 6 | IN− B | Inverting input of Amp B - matched to Pin 5 for precision instrumentation amplifier configurations. |
| 7 | OUT B | Amplifier B output - identical performance to Pin 1; may be paralleled for higher drive (with external resistors). |
| 8 | OUT C | Amplifier C output - third independent channel; no internal connection to other outputs. |
| 9 | IN− C | Inverting input of Amp C - electrically isolated; layout symmetry recommended for matching with Pins 2 and 6. |
| 10 | IN+ C | Non-inverting input of Amp C - supports multi-channel sensor interfaces (e.g., 3-axis accelerometer front-end). |
| 11 | VDD+ | Positive supply - accepts 2.7–8 V; must be decoupled with ≥0.1 µF ceramic capacitor near Pin 11. |
| 12 | IN+ D | Non-inverting input of Amp D - fourth channel; usable as reference buffer or active filter stage. |
| 13 | IN− D | Inverting input of Amp D - supports unity-gain inverter or transimpedance configuration with photodiode. |
| 14 | OUT D | Amplifier D output - fully specified rail-to-rail performance; enables 4-channel simultaneous sampling front-ends. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Delivers >99% of VDD− to VDD+ range under 10 kΩ load - eliminates need for level-shifting stages before SAR or sigma-delta ADCs. |
| Low input bias current (1 pA typ) | Minimizes voltage error across high-value feedback or sensor resistors (>10 MΩ), critical for pH or ion-selective electrode interfaces. |
| Specified for −40°C to 125°C | Guaranteed 950 µV VIO and 500 µA IDD across full automotive temperature range - suitable for engine control and cabin sensor modules. |
| Low noise (12 nV/√Hz) | Enables resolution of sub-millivolt signals without post-amplification; reduces requirement for external averaging or digital filtering. |
| Single-supply operation from 2.7 V | Supports direct integration into energy-harvesting systems powered by thin-film batteries or RF/thermal harvesters (<3 V output). |

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 |
|---|---|---|---|
| TLV2264IPWR | Higher 2.5 mV max VIO at 25°C; not specified for 950 µV over full temperature range. | Suitable for cost-sensitive industrial controls where ±1°C temperature accuracy is acceptable. | Select TLV2264IPWR only if VIO budget allows >2× degradation vs. TLV2264AIPWR at 125°C. |
| TLV2444CDR | Higher supply current (1.3 mA/amp), wider GBW (1.8 MHz), but no guaranteed VIO spec below 1.5 mV. | Better for AC-coupled audio or higher-speed sensor interfaces where bandwidth >1 MHz is required. | Choose TLV2444CDR when slew rate (1.2 V/µs) and GBW outweigh low-noise and ultra-low-IQ requirements. |
Compared with TLV2264IPWR and TLV2444CDR, the TLV2264AIPWR uniquely balances ultra-low input offset (950 µV), micropower operation (500 µA/amp), and rail-to-rail output in a single quad package - making it optimal for precision, battery-constrained measurement systems where long-term calibration stability is mandatory.

FAQ
What is the maximum input offset voltage specification for TLV2264AIPWR across temperature?
The TLV2264AIPWR has a maximum input offset voltage of 950 µV at TA = 25°C and 1500 µV over the full −40°C to 125°C operating range. This guaranteed spec enables precision DC-coupled designs in automotive and industrial environments where thermal drift must remain bounded.
Does TLV2264AIPWR support true rail-to-rail input common-mode range?
No - the TLV2264AIPWR supports rail-to-rail *output* swing and common-mode input range that *includes the negative rail* (VDD−), but does not extend to the positive rail. At VDD = 3 V, the common-mode input range is −0.3 V to 2.2 V, limiting high-side sensing without level translation.
Can TLV2264AIPWR drive a 10 kΩ load while maintaining rail-to-rail output swing?
Yes - the TLV2264AIPWR maintains rail-to-rail output swing into 10 kΩ loads across the full temperature range. Output voltage swing is specified down to 100 mV from each rail at IOL = 500 µA, which corresponds to ≤100 mV drop at 10 kΩ - well within rail-to-rail definition.
Is TLV2264AIPWR qualified for automotive applications?
Yes - the TLV2264AIPWR is offered in the Q-temp automotive grade (TLV2264AQD, TLV2264AQPWR) and meets AEC-Q100 qualification. While TLV2264AIPWR itself is the industrial-grade part, its electrical specs (−40°C to 125°C, 950 µV VIO) align with automotive subsystem requirements such as cabin temperature sensing.
What is the typical supply current per amplifier in TLV2264AIPWR at 3 V operation?
The typical supply current per amplifier in TLV2264AIPWR is 400 µA at VDD = 3 V and TA = 25°C, with a maximum of 500 µA per amplifier across temperature. Total device supply current is therefore 1.6 mA typical and 2.0 mA maximum under static conditions.
