Product details
Overview
TLV2264AIDR 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 sensor signal conditioning where high-impedance sources and single-supply ADC interfacing are required.
For engineers reviewing the TLV2264AIDR datasheet, TLV2264AIDR pinout, TLV2264AIDR application, or TLV2264AIDR equivalent, key selection criteria include guaranteed rail-to-rail output swing, ≤950 µV input offset (A-grade), −40°C to 125°C temperature range, SOIC-14 package compatibility, and CMOS input stage enabling pA-level bias current for piezoelectric transducer interfaces.
Technical Context
The TLV2264AIDR implements a CMOS-input, rail-to-rail output op-amp architecture with fully differential input stage and Class AB output stage. Its design supports both single-supply (2.7 V–8 V) and split-supply operation while maintaining common-mode input range extending to the negative rail.
It features internal trimming for precision offset performance (950 µV max), low-noise topology optimized for 1 kHz–10 kHz small-signal conditioning, and stable unity-gain operation with 55° phase margin into 50 kΩ//100 pF loads - enabling direct connection to SAR and delta-sigma ADCs without external buffering.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 8 V - supports battery-powered systems down to two alkaline cells or Li-ion single-cell operation. |
| Input Offset Voltage (max) | 950 µV at TA = 25°C - enables DC-coupled precision amplification without nulling circuitry in medical or industrial sensors. |
| Supply Current (per amp) | 500 µA max - allows four-channel operation at <2 mA total, suitable for always-on remote monitoring nodes. |
| Input Voltage Noise | 12 nV/√Hz at f = 1 kHz - preserves SNR in low-frequency sensor front-ends like strain gauges and thermopiles. |
| Output Swing | Rail-to-rail - delivers full dynamic range into ADCs with 0–VDD input ranges, eliminating level-shifting components. |
| Input Bias Current | 1 pA typ - prevents loading errors in high-Z sources such as pH electrodes and piezoelectric accelerometers. |
| Gain-Bandwidth Product | 0.67 MHz at VDD = 3 V - sufficient for anti-aliasing filtering and sensor gain stages up to ~100 kHz. |
Pinout & Package
TLV2264AIDR is housed in a 14-pin SOIC (D) package with standard pin spacing (1.27 mm pitch) and gull-wing leads. The package is RoHS-compliant, moisture-sensitive level 1, and rated for −40°C to 125°C operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives loads up to ±50 mA; rail-to-rail swing ensures full utilization of ADC reference range. |
| 2 | IN− A | Inverting input of Amp A - high-impedance CMOS node; requires matched trace impedance for optimal CMRR. |
| 3 | IN+ A | Non-inverting input of Amp A - accepts signals from VDD− to VDD+ −1.3 V; compatible with ground-referenced sensors. |
| 4 | VDD− / GND | Negative supply or ground reference - shared return path for all four amplifiers; must be low-impedance for noise immunity. |
| 5 | IN+ B | Non-inverting input of Amp B - identical electrical characteristics to Pin 3; enables independent dual-channel sensing paths. |
| 6 | IN− B | Inverting input of Amp B - symmetrical layout recommended to minimize inter-channel crosstalk in multi-sensor arrays. |
| 7 | OUT B | Amplifier B output - electrically isolated from OUT A; supports independent feedback networks for differential configurations. |
| 8 | OUT C | Amplifier C output - pin-compatible with OUT A/B; enables three-stage signal chain (gain/filter/buffer) within one IC. |
| 9 | IN− C | Inverting input of Amp C - shares same bias current and noise specs as Pins 2 and 6; suitable for active filter summing nodes. |
| 10 | IN+ C | Non-inverting input of Amp C - supports reference voltage buffering or precision voltage follower applications. |
| 11 | VDD+ | Positive supply - decoupling capacitor (0.1 µF ceramic) required within 5 mm for stable high-frequency performance. |
| 12 | IN+ D | Non-inverting input of Amp D - enables fourth independent channel for redundancy, calibration, or multi-axis sensing. |
| 13 | IN− D | Inverting input of Amp D - matches input capacitance (8 pF) of other channels; critical for matched AC response in synchronized sampling. |
| 14 | OUT D | Amplifier D output - completes quad configuration; supports simultaneous analog acquisition across four sensor elements. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Delivers full-scale output from VDD− to VDD+ −100 mV at IOUT = ±1 mA, maximizing ADC effective resolution. |

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 |
|---|---|---|---|
| TLV2264IDR | Higher 2.5 mV max input offset voltage; otherwise identical electrical specs and pinout. | Suitable for non-precision applications like general-purpose buffering or comparator hysteresis generation. | Select TLV2264IDR when offset-critical calibration is performed digitally or not required. |
| TLV2444CDR | Higher supply current (1.4 mA/amp), wider GBW (1.8 MHz), but no guaranteed low-offset grade; not qualified for −40°C to 125°C. | Better suited for higher-speed signal chains requiring >100 kHz bandwidth, but unsuitable for automotive or extended-temperature industrial use. | Choose TLV2444CDR only if bandwidth >1 MHz is mandatory and temperature range is limited to 0°C–70°C. |
Compared with TLV2264IDR, the TLV2264AIDR provides tighter offset control essential for DC-coupled sensor interfaces; versus TLV2444CDR, it trades bandwidth for lower power and extended temperature qualification - making it optimal for precision, low-power, wide-temperature embedded systems.

FAQ
What is the maximum operating temperature range for TLV2264AIDR?
The TLV2264AIDR is specified for continuous operation from −40°C to +125°C ambient temperature. This extended range is validated per automotive AEC-Q100 stress testing protocols and supports deployment in engine control units, industrial motor drives, and outdoor environmental sensors where thermal extremes occur.
Does TLV2264AIDR support true rail-to-rail input capability?
No, the TLV2264AIDR features rail-to-rail *output* swing but its common-mode input voltage range extends only to the negative rail (VDD−) and up to VDD+ −1.3 V at 3 V supply. This allows ground-referenced inputs but does not support full VDD+ input - unlike some newer TI op-amps such as the OPA333.
Can TLV2264AIDR drive capacitive loads directly?
The TLV2264AIDR is stable with capacitive loads up to 100 pF when configured for unity gain, as confirmed by 55° phase margin measurements. For loads exceeding 100 pF - such as ADC input capacitors or long PCB traces - an isolation resistor (10–100 Ω) between output and load is recommended to maintain stability.
Is TLV2264AIDR pin-compatible with other quad op-amps in SOIC-14 packages?
Yes, TLV2264AIDR uses the industry-standard SOIC-14 pinout for quad op-amps (pin 1 = OUT A, pin 4 = GND, pin 8 = OUT C, pin 11 = VDD+, etc.). It is mechanically and electrically pin-compatible with TLV2264IDR, TLV2264QDR, and legacy TLC2274 variants - though electrical performance (offset, noise, supply current) differs significantly.
What is the typical supply current consumption of TLV2264AIDR at 5 V operation?
At VDD = 5 V and TA = 25°C, the TLV2264AIDR draws 0.8 mA to 1 mA total supply current (200–250 µA per amplifier). This value remains stable across the full −40°C to 125°C range, with a maximum of 1 mA specified under worst-case conditions - enabling predictable power budgeting in energy-constrained designs.
