Product details
Overview
TLV9064SIRTER from Texas Instruments is a quad-channel, rail-to-rail input/output operational amplifier optimized for cost-sensitive, low-voltage systems. It delivers 10MHz unity-gain bandwidth, ±0.3mV input offset voltage, 10nV/√Hz input voltage noise, 538µA quiescent current per channel, and operates from 1.8V to 5.5V supply. It supports shutdown mode (IQSD < 1.5µA) and is specified for –40°C to 125°C operation-ideal for motor control feedback loops in HVAC and e-bike power stages.
For engineers reviewing the TLV9064SIRTER datasheet, TLV9064SIRTER pinout, TLV9064SIRTER application, or TLV9064SIRTER equivalent, this page provides verified package mapping (WQFN-16), confirmed shutdown pin behavior (SHDN12/SHDN34), real-world capacitive load stability data (up to 100pF+), and validated alternatives for low-power, high-precision sensing in battery-powered industrial equipment.
Technical Context
The TLV9064SIRTER integrates two independent shutdown controls (SHDN12 for channels 1–2, SHDN34 for channels 3–4), enabling selective channel power gating without affecting others. Its resistive open-loop output impedance (100Ω at 10MHz) simplifies compensation with capacitive loads beyond typical op-amp limits.
Designed for single-supply operation down to 1.8V, it maintains rail-to-rail input common-mode range (V– – 0.1V to V+ + 0.1V) and output swing within 20mV of rails (at 5.5V, RL = 10kΩ), supporting precision signal conditioning in space-constrained, low-power embedded systems.
Key Specifications

|---|---|
| Unity-gain bandwidth | 10MHz - enables stable closed-loop operation up to 100kHz with gain ≥10, suitable for active filter and sensor signal chain stages. |
| Input offset voltage | ±0.3mV (typ) - ensures ≤0.6mV total error in DC-coupled low-side current sensing at room temperature. |
| Quiescent current per channel | 538µA - allows four amplifiers to operate under 2.2mA total, critical for always-on battery-powered smoke detectors. |
| Supply voltage range | 1.8V to 5.5V - supports direct interface with Li-ion (3.0–4.2V), 3.3V logic, and 1.8V microcontrollers without level-shifting. |
| Shutdown current (per amp) | 0.5µA (typ) - reduces total system standby current by >99% when unused channels are disabled. |
| Input voltage noise density | 10nV/√Hz at 10kHz - preserves SNR in 20kHz-bandwidth analog front-ends for wearable biopotential monitoring. |
| Open-loop output impedance | 100Ω (resistive, f = 10MHz) - eliminates need for isolation resistors when driving 100pF+ capacitive loads like LCD bias networks. |
Pinout & Package
RTE package: 16-pin WQFN (3.0mm × 3.0mm, 0.5mm pitch) with exposed thermal pad connected to V– for enhanced thermal performance (RθJA = 65.1°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1– (16) | Inverting input, channel 1 | Accepts differential signals referenced to V–; supports single-ended or fully differential configurations. |
| IN1+ (1) | Noninverting input, channel 1 | High-impedance node (IB = 0.5pA) minimizes loading on high-Z sensors like thermistors. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV9064IRTER | No shutdown pins; fixed quad configuration without power-gating capability. | Suitable only for always-on signal paths; cannot support dynamic power management. | Select TLV9064IRTER if system requires lowest BOM cost and all four amplifiers operate continuously. |
| OPA4316IPWR | Higher quiescent current (400µA/channel), no integrated RFI filter, wider offset (±0.5mV), but higher CMRR (103dB). | Better for precision DC measurements where EMI immunity is handled externally; less suited for noisy motor environments. | Choose OPA4316IPWR when ultra-low drift (<0.15µV/°C) and high DC accuracy outweigh low-power and EMI robustness requirements. |
Compared with TLV9064IRTER and OPA4316IPWR, TLV9064SIRTER uniquely combines shutdown control, integrated EMI filtering, and sub-1µA standby current-making it optimal for battery-powered, noise-prone applications requiring selective channel activation.

FAQ
What is the shutdown pin configuration for TLV9064SIRTER?
TLV9064SIRTER features two dedicated shutdown pins: SHDN12 (pin 6) controls channels 1 and 2, while SHDN34 (pin 7) controls channels 3 and 4. Both are active-high with thresholds of V– + 0.9V to V– + 1.1V. When pulled low, each pair draws <1.5µA total quiescent current. This dual-control architecture enables granular power management in multi-channel systems such as 3-phase motor controllers using TLV9064SIRTER.
Does TLV9064SIRTER support true rail-to-rail input and output operation?
Yes, TLV9064SIRTER supports rail-to-rail input common-mode range from V– – 0.1V to V+ + 0.1V and rail-to-rail output swing within 20mV of each supply rail (at 5.5V, RL = 10kΩ). This allows full utilization of the supply voltage in single-supply configurations-for example, interfacing directly with a 3.3V ADC without level-shifting circuitry. The specification is guaranteed across –40°C to 125°C, making TLV9064SIRTER suitable for automotive HVAC and industrial motor control applications.
What is the maximum capacitive load TLV9064SIRTER can drive stably?
TLV9064SIRTER is characterized for stable operation with up to 100pF capacitive load in unity-gain configuration. Its resistive open-loop output impedance (100Ω at 10MHz) significantly improves phase margin compared to conventional op-amps, allowing reliable use with larger loads-such as LCD bias networks or long PCB traces-without requiring external isolation resistors. Data sheet Figure 6-23 confirms <5% overshoot at 100pF, validating TLV9064SIRTER's robust capacitive drive capability in real-world layouts.
How does TLV9064SIRTER handle EMI and RFI interference?
TLV9064SIRTER integrates an internal RFI and EMI rejection filter, providing >40dB attenuation of 900MHz cellular band noise without external components. This is verified in TI's characterization reports and eliminates the need for discrete ferrite beads or RC filters in noisy environments like e-bike motor controllers or HVAC inverters. The filter is co-designed with the input stage, preserving DC accuracy and noise performance-ensuring that TLV9064SIRTER maintains its 10nV/√Hz noise density and ±0.3mV offset even under strong RF fields.
What is the thermal performance of TLV9064SIRTER in its WQFN package?
TLV9064SIRTER in the RTE (WQFN-16) package has a junction-to-ambient thermal resistance (RθJA) of 65.1°C/W and junction-to-board (RθJB) of 40.4°C/W when the exposed thermal pad is soldered to a 1-in² copper pour. Its low RθJC(top) of 67.9°C/W and bottom-side RθJC(bot) of 23.8°C/W confirm efficient heat transfer through both top and bottom surfaces. This thermal profile supports continuous operation at full load in ambient temperatures up to 125°C-critical for TLV9064SIRTER deployment in enclosed power modules and under-hood automotive systems.
