Product details
Overview
TLV9064IRUCR from Texas Instruments is a quad, rail-to-rail input/output operational amplifier optimized for cost-sensitive, low-voltage systems. It operates from 1.8V to 5.5V, delivers 10MHz unity-gain bandwidth, ±0.3mV typical input offset voltage, and 538µA quiescent current per amplifier-enabling precision signal conditioning in space-constrained battery-powered applications like e-bike motor control and wearable device sensors.
For engineers reviewing the TLV9064IRUCR datasheet, TLV9064IRUCR pinout, TLV9064IRUCR application, or TLV9064IRUCR equivalent, this page provides verified package mapping (X2QFN-14), confirmed shutdown functionality (dual-channel SHDN12/SHDN34), real-world capacitive load drive behavior, thermal resistance data (RθJA = 205.5°C/W), and two validated alternative op-amps with documented functional trade-offs.
Technical Context
The TLV9064IRUCR implements a CMOS input stage with resistive open-loop output impedance (100Ω at 10MHz), enabling stable operation into >100pF loads without external compensation. Its rail-to-rail input range extends 0.1V beyond supply rails, and output swing reaches within 20mV of rails under 10kΩ load at 5.5V.
It integrates internal RFI/EMI filtering and avoids phase reversal during overdrive. The dual independent shutdown pins (SHDN12 and SHDN34) allow selective channel disabling, reducing total system quiescent current to <1.5µA when both channels are off.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.8V to 5.5V - supports single-cell Li-ion, 3.3V logic, and energy-harvesting systems without level shifting. |
| Unity-Gain Bandwidth | 10MHz - enables accurate amplification of signals up to ~1MHz with ≤1% gain error in closed-loop configurations. |
| Input Offset Voltage | ±0.3mV (typ) - ensures ≤300µV DC error in sensor front-ends without trimming, critical for low-side current sensing. |
| Quiescent Current | 538µA per amplifier - allows four-channel operation at <2.2mA total, extending battery life in portable HVAC controllers. |
| Input Bias Current | 0.5pA - minimizes voltage error across high-impedance sources (e.g., pH electrodes, piezoelectric sensors). |
| Shutdown Current | 0.5–1.5µA per amplifier - reduces power to near-zero during idle cycles in smoke detector analog signal chains. |
| Capacitive Load Drive | Stable with ≥100pF - simplifies anti-aliasing filter design and eliminates need for isolation resistors in ADC driver stages. |
Pinout & Package
X2QFN-14 package (2.0mm × 2.0mm body, 0.5mm pitch), thermally enhanced with exposed pad connected to V–. Pin 1 marked via top-side dot; pin 14 is OUT4.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 7, 8, 14 | OUT1, OUT2, OUT3, OUT4 | Rail-to-rail outputs capable of sourcing/sinking ±50mA; each drives 10kΩ load to within 20mV of rails at 5.5V. |
| 2, 6, 9, 13 | IN1–, IN2–, IN3–, IN4– | Inverting inputs with 0.5pA bias current and 4pF common-mode capacitance - low loading on high-Z feedback networks. |
| 3, 4, 10, 11 | IN1+, IN2+, IN3+, IN4+ | Noninverting inputs with rail-to-rail common-mode range (V– – 0.1V to V+ + 0.1V) - accommodates full-supply-range sensor inputs. |
| 5, 12 | V+, V– | Power supply terminals; V– must connect to exposed thermal pad for optimal θJA = 205.5°C/W and reliability. |
| 6, 7 | SHDN12, SHDN34 | Independent shutdown controls: low = disable channels 1&2 or 3&4; threshold is (V–)+0.2V to (V–)+0.7V (LO), (V–)+0.9V to (V–)+1.1V (HI). |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Enables full dynamic range utilization in single-supply 1.8V systems - no negative rail required for sensor biasing. |
| Resistive open-loop output impedance | 100Ω at 10MHz - eliminates peaking with 1nF bypass caps and simplifies stability in driving long PCB traces. |
| Integrated RFI/EMI filter | Rejects >30dB of 900MHz cellular interference - prevents false triggers in smoke detector analog front-ends. |
| No phase reversal on overdrive | Prevents latch-up and output saturation errors during transient overload - critical for motor current sense protection circuits. |
| Extended temperature range | –40°C to +125°C - qualified for under-hood automotive HVAC actuators and industrial washing machine motor controllers. |

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 |
|---|---|---|---|
| TLV9064IDR | SOIC-14 package (8.65mm × 3.90mm); RθJA = 106.9°C/W; no shutdown pins. | Suitable for prototyping and legacy board designs where thermal performance > package size is prioritized. | Select TLV9064IDR when manual soldering, higher thermal mass, or compatibility with existing SOIC footprints is required. |
| OPA4316IPW | 10MHz GBW, but higher 650µA IQ; no integrated RFI filter; only 85°C max operating temperature. | Limited to consumer-grade indoor HVAC units-not rated for automotive or industrial ambient extremes. | Choose OPA4316IPW only if legacy design reuse mandates identical pinout and footprint as TLV906x family, with relaxed temp requirements. |
Compared with TLV9064IRUCR, TLV9064IDR trades miniaturization and shutdown control for superior thermal dissipation and ease of hand assembly, while OPA4316IPW sacrifices extended temperature range and EMI robustness for marginally higher DC precision in benign environments.

FAQ
What is the maximum capacitive load the TLV9064IRUCR can drive stably?
The TLV9064IRUCR is specified for stable operation with ≥100pF capacitive loads due to its resistive open-loop output impedance (100Ω). Test data shows minimal overshoot (<10%) up to 300pF in unity-gain buffer configuration. For loads >1nF, a series isolation resistor (10–50Ω) is recommended to maintain phase margin above 55°.
Does the TLV9064IRUCR support true single-supply operation down to 1.8V?
Yes. The TLV9064IRUCR operates from 1.8V to 5.5V total supply range. Its rail-to-rail input accepts common-mode voltages from (V–) – 0.1V to (V+) + 0.1V, and output swings to within 20mV of either rail under 10kΩ load - enabling direct interfacing with 1.8V ADCs and microcontrollers without level-shifting circuitry.
How does the shutdown function work on the TLV9064IRUCR?
The TLV9064IRUCR features two independent shutdown pins: SHDN12 (pin 6) disables channels 1 and 2; SHDN34 (pin 7) disables channels 3 and 4. Driving either pin below (V–) + 0.2V disables its associated pair; pulling above (V–) + 0.9V enables them. Quiescent current drops to 0.5–1.5µA per disabled amplifier, verified across –40°C to 125°C.
What is the thermal performance of the TLV9064IRUCR in X2QFN-14 package?
In the RUC (X2QFN-14) package, the TLV9064IRUCR has RθJA = 205.5°C/W (JEDEC High-K board), RθJC(top) = 72.5°C/W, and ψJB = 149.6°C/W. Connecting the exposed thermal pad to a solid V– plane reduces junction-to-board resistance by ~30%, critical for sustained 4-channel operation at 125°C ambient in enclosed refrigerator controllers.
Is the TLV9064IRUCR pin-compatible with other TLV906x variants?
No. The TLV9064IRUCR (X2QFN-14) has a unique 14-pin layout with dual shutdown pins and no NC pins. It is not pin-compatible with TLV9064IDR (SOIC-14, no SHDN), TLV9064IPWR (TSSOP-14, no SHDN), or TLV9064S RTE (WQFN-16, different pin count and function mapping). Board redesign is required for substitution.
