Product details
Overview
TLV9064IDR from Texas Instruments is a quad rail-to-rail input/output operational amplifier optimized for cost-sensitive, low-voltage systems (1.8V to 5.5V). It delivers 10MHz unity-gain bandwidth, ±0.3mV typical input offset voltage, 10nV/√Hz input voltage noise, 538µA quiescent current per amplifier, and operates across –40°C to 125°C. It is used in low-side current sensing, HVAC control, and wearable device signal conditioning.
For engineers reviewing the TLV9064IDR datasheet, TLV9064IDR pinout, TLV9064IDR application, or TLV9064IDR equivalent, key selection considerations include its resistive open-loop output impedance (simplifying stability with >100pF loads), internal RFI/EMI filtering, shutdown capability (TLV9064S variant), and SOIC-14 package compatibility with legacy layouts.
Technical Context
The TLV9064IDR employs a CMOS input stage enabling ultra-low input bias current (0.5pA) and rail-to-rail common-mode input range extending 0.1V beyond supply rails. Its unity-gain stable architecture integrates an internal RFI/EMI filter and avoids phase reversal during overdrive.
Designed for single-supply operation down to 1.8V, it features a resistive open-loop output impedance (~100Ω at 10MHz), which reduces peaking and simplifies compensation when driving capacitive loads-unlike conventional op-amps requiring external isolation resistors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Unity-gain bandwidth | 10MHz - supports fast-settling signal conditioning in motor control feedback loops and active filters. |
| Input offset voltage | ±0.3mV (typ) - enables accurate DC-coupled amplification in precision low-side current sensing. |
| Quiescent current | 538µA per amplifier - allows four-channel operation within tight power budgets of battery-powered wearables. |
| Supply voltage range | 1.8V to 5.5V - compatible with Li-ion, 3.3V, and 5V system rails without level-shifting. |
| Input voltage noise | 10nV/√Hz at 10kHz - preserves SNR in sensor front-ends like smoke detector analog signal chains. |
| Operating temperature | –40°C to 125°C - qualified for under-hood automotive HVAC modules and industrial motor drives. |
| CMRR | 103dB (typ) at 5.5V - rejects common-mode interference in noisy industrial environments. |
Pinout & Package
TLV9064IDR is supplied in a 14-pin SOIC (D) package measuring 8.65mm × 3.90mm, with exposed pad optional per thermal design requirements. Pin 1 is OUT1; pin 14 is OUT4; V– (pin 11) and V+ (pin 4) are shared supply rails; all four channels have dedicated IN+/IN– pairs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 7, 8, 14 | OUT1–OUT4 | Amplifier outputs - rail-to-rail swing supports full dynamic range utilization in single-supply data acquisition. |
| 2, 6, 9, 13 | IN1–, IN2–, IN3–, IN4– | Inverting inputs - high-impedance CMOS nodes enable direct connection to high-Z sensors without loading. |
| 3, 5, 10, 12 | IN1+, IN2+, IN3+, IN4+ | Noninverting inputs - rail-to-rail common-mode range (V– – 0.1V to V+ + 0.1V) accommodates ground-referenced or biased signals. |
| 4 | V+ | Positive supply - accepts 1.8V–5.5V; decoupling capacitor required near pin for stability. |
| 11 | V– | Negative supply / ground - serves as reference for single-supply operation and thermal pad connection point. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Enables full-scale signal swing in 1.8V systems, maximizing ADC resolution without level-shifting circuitry. |
| Resistive open-loop output impedance | ~100Ω at 10MHz - eliminates need for series output resistors when driving 100–500pF capacitive loads (e.g., long PCB traces, ADC inputs). |
| Internal RFI/EMI filter | Rejects high-frequency noise from switching regulators and RF sources, reducing post-layout filtering effort. |
| Low input bias current | 0.5pA - prevents voltage error in high-impedance transducer interfaces (e.g., thermopiles, pH electrodes). |
| Extended temperature range | –40°C to 125°C - meets AEC-Q100 Grade 1 stress requirements for automotive cabin and powertrain subsystems. |

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 |
|---|---|---|---|
| TLV9064IPWR | TSSOP-14 package (5.00mm × 4.40mm); identical electrical specs and pinout; slightly higher RθJA (135.8°C/W vs 106.9°C/W). | Better suited for space-constrained PCBs where SOIC footprint is prohibitive; thermal performance requires careful layout. | Select TLV9064IPWR when board area is critical and thermal margin allows TSSOP mounting. |
| OPA4316IPW | Higher quiescent current (1mA per amp); lower noise (8.5nV/√Hz); same 10MHz GBW; wider supply range (1.8V–5.5V); no integrated RFI filter. | Preferred for ultra-low-noise sensor front-ends where power budget permits; lacks EMI hardening for noisy motor-drive environments. | Choose OPA4316IPW only when noise dominates over EMI robustness and power constraints. |
Compared with TLV9064IPWR, TLV9064IDR offers superior thermal dissipation in SOIC packaging, while OPA4316IPW trades higher power for marginally better noise-neither is pin-compatible with TLV9064S shutdown variants.

FAQ
What is the maximum capacitive load the TLV9064IDR can drive without external compensation?
The TLV9064IDR features a resistive open-loop output impedance (~100Ω), enabling stable operation with capacitive loads up to 500pF without series isolation resistors. This is confirmed by small-signal overshoot testing showing <10% peaking at 300pF in unity-gain configuration. For loads exceeding 500pF, a small series resistor (10–22Ω) at the output is recommended to maintain phase margin above 45°.
Does the TLV9064IDR support true single-supply operation with input signals at ground potential?
Yes. The TLV9064IDR's rail-to-rail input stage allows common-mode voltage from (V–) – 0.1V to (V+) + 0.1V. When V– = 0V (ground), inputs can accept signals from –0.1V to V+ + 0.1V, enabling direct interfacing with ground-referenced sensors and transducers without level-shifting circuitry-critical for low-side current sensing applications.
How does the TLV9064IDR's EMI rejection compare to standard CMOS op-amps?
The TLV9064IDR integrates an internal RFI/EMI filter that attenuates high-frequency interference (30MHz–1GHz) by >30dB, verified via standardized EMI immunity testing. Unlike unfiltered op-amps such as MCP6004, this feature prevents rectification of RF energy into DC offset errors-making TLV9064IDR suitable for use near switching power supplies and wireless modules without additional ferrite beads or RC filters.
Is the TLV9064IDR pin-compatible with any industry-standard quad op-amp footprints?
Yes. TLV9064IDR uses the standard SOIC-14 footprint (8.65mm × 3.90mm), matching legacy quad op-amps including LM324, TL074, and MCP6004. Pin assignments for supply (V+, V–), inputs (IN+, IN– per channel), and outputs (OUT1–OUT4) follow conventional SOIC-14 quad op-amp conventions-enabling drop-in replacement in existing designs with no PCB revision required.
What is the typical power supply rejection ratio (PSRR) of the TLV9064IDR across its operating voltage range?
The TLV9064IDR delivers a typical PSRR of ±7 µV/V (111dB) at 1.8V supply and ±80 µV/V (102dB) at 5.5V supply, measured across DC to 100kHz. This high PSRR ensures minimal supply ripple coupling into amplified signals-especially valuable in mixed-signal systems where analog sections share noisy digital rails, such as in smart appliance mainboards.
