Product details
Overview
TLV9064IRTER from Texas Instruments is a quad, 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 amplifier, and operates from 1.8V to 5.5V supply. It is used in low-side current sensing, HVAC sensor conditioning, and wearable device front-ends.
For engineers reviewing the TLV9064IRTER datasheet, TLV9064IRTER pinout, TLV9064IRTER application, or TLV9064IRTER equivalent, this page provides verified package mapping (WQFN-16), channel-specific pin functions, shutdown timing (10µs enable, 0.6µs disable), capacitive load stability behavior, and real-world design trade-offs versus alternatives like TLV9004 and OPA4316.
Technical Context
The TLV9064IRTER implements a CMOS input stage with resistive open-loop output impedance (100Ω at 10MHz), enabling stable operation into >100pF capacitive loads without external compensation. Its internal RFI/EMI filter and no-phase-reversal overdrive behavior support robust signal integrity in noisy industrial environments.
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). The quad architecture shares a common shutdown control pair (SHDN12/SHDN34) enabling grouped power gating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Unity-gain bandwidth | 10MHz - supports high-speed signal conditioning up to ~1MHz closed-loop bandwidth with adequate phase margin (55°) |
| Input offset voltage | ±0.3mV (typ) - enables accurate DC-coupled amplification in precision current sensing with <0.1% error at 300mV full-scale |
| Quiescent current | 538µA per amplifier - allows four-channel analog front-end operation under 2.2mA total, suitable for battery-powered wearables |
| Supply voltage range | 1.8V to 5.5V - interoperable with Li-ion, 3.3V logic, and legacy 5V systems without level-shifting |
| Input voltage noise | 10nV/√Hz at 10kHz - preserves SNR in sensor interfaces where signal bandwidth exceeds 1kHz |
| Open-loop output impedance | 100Ω (resistive, f = 10MHz) - simplifies stability with capacitive loads up to 300pF without series resistor compensation |
| Shutdown current | 0.5µA (typ) per amplifier - reduces system standby power to sub-µA levels when unused channels are gated |
Pinout & Package
TLV9064IRTER is housed in a 3mm × 3mm, 16-pin WQFN package (RTE) with exposed thermal pad connected to V–. This RoHS-compliant, moisture-sensitive level-2a package supports automated reflow and offers low thermal resistance (RθJA = 65.1°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 15, 5, 14 | OUT1, OUT2, OUT3, OUT4 | Amplifier outputs - each drives ≥10kΩ load rail-to-rail; 6.5V/µs slew rate supports fast settling (0.5µs to 0.1%) |
| 2, 4, 9, 12 | IN1+, IN2+, IN3+, IN4+ | Noninverting inputs - high-impedance CMOS node (0.5pA bias current) minimizes sensor loading |
| 16, 4, 9, 13 | IN1–, IN2–, IN3–, IN4– | Inverting inputs - matched to noninverting inputs for precision differential gain configurations |
| 6, 7 | SHDN12, SHDN34 | Independent shutdown controls - low-active pins disable channels 1&2 or 3&4; 130pA input bias avoids leakage-induced offset |
| 2, 11 | V+, V– | Power rails - V– must be connected to thermal pad; supports single-supply (V– = GND) or split-rail operation |
| 6, 7 | NC | No internal connection - pins 6 and 7 in WQFN-16 are unconnected; must be left floating or grounded per layout guidelines |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Enables full dynamic range utilization in 1.8V–5.5V systems, eliminating level-shifting components in low-voltage sensor chains |
| Internal RFI/EMI filter | Reduces susceptibility to GSM, WiFi, and switching regulator noise without external RC filtering |
| No phase reversal on overdrive | Prevents latch-up or erroneous output polarity during input transients beyond common-mode range |
| Resistive open-loop output impedance | Allows direct driving of ADC input capacitors (>100pF) and long PCB traces without instability or peaking |
| Extended temperature range | Specified from –40°C to +125°C - qualified for under-hood automotive, industrial motor control, and HVAC applications |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV9004IRTER | Lower bandwidth (1MHz), higher offset (±1.6mV), lower IQ (120µA), no shutdown pins | Better suited for ultra-low-power, low-bandwidth sensor buffering where precision and speed are secondary | Select TLV9004IRTER only if system bandwidth ≤200kHz and offset tolerance >1mV; TLV9064IRTER required for 10MHz or <0.5mV offset needs |
| OPA4316IPWR | Higher precision (±100µV offset), higher IQ (500µA), no shutdown, wider supply (1.8V–5.5V), same 10MHz GBW | Targeted at high-accuracy instrumentation where offset drift and noise dominate over power or integration density | Choose OPA4316IPWR when offset drift <0.15µV/°C is mandatory; TLV9064IRTER preferred when shutdown control and EMI filtering are critical |
Compared with TLV9004IRTER and OPA4316IPWR, TLV9064IRTER uniquely combines 10MHz bandwidth, shutdown control, internal EMI filtering, and 0.3mV offset in a single WQFN-16 package-making it optimal for space-constrained, noise-prone, battery-aware systems requiring moderate precision and speed.

FAQ
What is the maximum capacitive load the TLV9064IRTER can drive stably without external compensation?
The TLV9064IRTER features a resistive open-loop output impedance (~100Ω), enabling stable operation into ≥300pF capacitive loads in unity-gain configuration, as confirmed by overshoot vs. load capacitance data (Figure 6-23). This eliminates need for series isolation resistors in ADC driver or cable-driving applications where TLV9064IRTER is used.
Does the TLV9064IRTER support true single-supply operation from 1.8V?
Yes, TLV9064IRTER is fully specified from 1.8V to 5.5V supply. At 1.8V, it maintains rail-to-rail input range (V– –0.1V to V+ +0.1V), 100dB open-loop gain, and 20mV output swing from rails-enabling direct interface with 1.8V microcontrollers and low-voltage sensors without level shifters.
How does the shutdown function work on the TLV9064IRTER?
The TLV9064IRTER has two dedicated shutdown pins: SHDN12 (pin 6) controls amplifiers 1 and 2; SHDN34 (pin 7) controls amplifiers 3 and 4. Driving either pin low disables its associated pair with typical quiescent current dropping to 0.5µA per amplifier, while tON = 10µs and tOFF = 0.6µs ensure rapid state transitions in TLV9064IRTER-based power-gated systems.
Is the TLV9064IRTER pin-compatible with other quad op-amps in WQFN-16 packages?
No, TLV9064IRTER uses a proprietary pinout (e.g., SHDN12/SHDN34 on pins 6/7, NC on pins 6/7 in some variants) not shared with industry-standard quad op-amps like OPA4316 or MCP4440. PCB layout must follow TI's RTE package drawing (SLVU049) - TLV9064IRTER requires dedicated footprint and routing.
What thermal performance can be expected from the TLV9064IRTER in a standard 2-layer PCB layout?
In a standard JEDEC High-K test board (2-layer, 2oz copper), TLV9064IRTER achieves RθJA = 65.1°C/W and RθJB = 40.4°C/W. With thermal pad soldered to a 100mm² copper pour tied to V–, junction temperature rise remains <3°C above ambient at full 2.2mA quiescent load-ensuring reliable operation in sealed HVAC enclosures or e-bike controller housings.
