Product details
Overview
PTLV9054SIRTER from Texas Instruments is a quad-channel, rail-to-rail input/output operational amplifier with 5MHz unity-gain bandwidth, 15V/µs slew rate, and 330µA quiescent current per channel. It operates from 1.8V to 6.0V supply, features shutdown control (SHDN12/SHDN34), and delivers ±0.33mV input offset voltage - optimized for low-power sensor signal conditioning and current shunt monitoring in white goods and HVAC systems.
For engineers reviewing the PTLV9054SIRTER datasheet, PTLV9054SIRTER pinout, PTLV9054SIRTER application, or PTLV9054SIRTER equivalent, this page provides verified package mapping (WQFN-16), functional pin definitions, real-world design value of shutdown-enabled power gating, and validated alternative options for quad RRIO op amp selection in space-constrained industrial embedded designs.
Technical Context
The PTLV9054SIRTER implements a CMOS input stage with 2pA typical input bias current and 15nV/√Hz input voltage noise density at 10kHz. Its unity-gain stable architecture supports capacitive loads up to 150pF without external compensation, enabled by internal RFI/EMI filtering and absence of phase reversal under overdrive.
It integrates dual independent shutdown controls (SHDN12 for channels 1–2, SHDN34 for channels 3–4), allowing selective channel disablement with 6µs turn-off and 10µs partial-enable timing. The device maintains rail-to-rail output swing within 16mV of rails (at 10kΩ load, 5.5V supply) across –40°C to +125°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | Quad - enables single-package implementation of multi-sensor front-ends or multi-stage filtering without inter-chip matching drift. |
| Supply Voltage Range | 1.8V to 6.0V - supports direct interface with Li-ion battery systems (3.0–4.2V), 3.3V logic, and 5V legacy interfaces without level-shifting. |
| Unity-Gain Bandwidth | 5MHz - sufficient for anti-aliasing filters up to ~800kHz and fast-settling current sense amplifiers in DC motor control loops. |
| Slew Rate | 15V/µs - ensures <1µs 0.1% settling for 2V steps with 100pF load, critical for pulse-width modulated signal conditioning. |
| Input Offset Voltage | ±0.33mV (typ) - reduces gain error to <0.033% in 10V full-scale current shunt monitors with 100× gain. |
| Quiescent Current | 330µA per channel - enables always-on sensor nodes with <1.4mA total active current, extending battery life in portable HVAC diagnostics. |
| Shutdown Current | <1µA total (all channels disabled) - allows microamp-level system sleep states while retaining configuration integrity. |
Pinout & Package
PTLV9054SIRTER is housed in a 3mm × 3mm, 16-pin WQFN package with exposed thermal pad connected to V–. The package supports high-density PCB layouts and efficient heat dissipation in thermally constrained modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1+, IN1− | Noninverting/inverting inputs, channel 1 | Differential pair inputs with 4pF common-mode capacitance - require matched trace lengths to minimize EMI-induced common-mode rejection degradation. |
| IN2+, IN2− | Noninverting/inverting inputs, channel 2 | Electrically isolated from channel 1 inputs - enables independent gain/feedback networks without crosstalk (115dB dc channel separation). |
| IN3+, IN3−, IN4+, IN4− | Inputs for channels 3 and 4 | Identical input structure to channels 1–2 - permits identical layout practices across all four amplifiers for production consistency. |
| OUT1–OUT4 | Amplifier outputs | Rail-to-rail capable with 250Ω open-loop output impedance - drives 10kΩ loads to within 16mV of rails; stable with ≥150pF capacitive loads. |
| V+, V− | Positive/negative supply pins | V− must connect to exposed thermal pad - improves thermal resistance (RθJB = 40.5°C/W) and prevents thermal runaway during sustained output current. |
| SHDN12, SHDN34 | Channel-group shutdown controls | Active-high logic; 0.2–0.7V low threshold ensures robust noise immunity in noisy industrial environments; 10kΩ pull-down recommended for default-disable. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Enables full dynamic range utilization in single-supply 3.3V systems - eliminates need for level-shifting circuitry in ADC driver stages. |
| 15V/µs slew rate | Supports accurate amplification of fast transients (e.g., motor commutation spikes) without slew-induced distortion in closed-loop current sensing. |
| Internal RFI/EMI filter | Reduces susceptibility to 800MHz–2.5GHz cellular and Wi-Fi interference - critical for reliable operation in smart appliance RF environments. |
| Shutdown mode (≤1µA) | Permits dynamic power scaling: disable unused channels during idle periods in multi-sensor data loggers to extend battery runtime by >40%. |
| –40°C to +125°C operation | Validated performance across automotive under-hood and industrial motor drive temperature ranges - no derating required up to 125°C junction. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad rail-to-rail op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV9054IRTER | No shutdown functionality; identical pinout, specs, and WQFN-16 package. | Not suitable where dynamic power gating is required; lacks SHDN12/SHDN34 pins (replaced by NC). | Select when lowest cost is prioritized and all four channels operate continuously - saves $0.08/unit at 10k volume. |
| OPA4991IPWR | Higher 4.5MHz GBW, 21V/µs slew rate, 5.5V max supply; SOIC-14 package (larger footprint). | Better suited for precision 24-bit delta-sigma ADC drivers requiring lower THD+N (0.00015% vs 0.0006%). | Choose for metrology-grade signal chains where 125°C operation is not required - adds 2.5mm × 4.4mm board area. |
Compared with TLV9054IRTER, PTLV9054SIRTER adds independent dual shutdown control for power optimization without sacrificing speed or precision; versus OPA4991IPWR, it trades marginal performance uplift for smaller size, wider temperature range, and lower supply voltage compatibility - making it optimal for space- and energy-constrained industrial edge nodes.

FAQ
What is the maximum capacitive load the PTLV9054SIRTER can drive while maintaining stability?
The PTLV9054SIRTER is specified to remain stable with up to 150pF capacitive load at unity gain, as confirmed by phase margin measurements ≥60° across temperature and supply voltage. Its internal compensation and low 250Ω open-loop output impedance allow safe operation with typical PCB trace capacitance and small ceramic decoupling caps without external isolation resistors.
Does the PTLV9054SIRTER support true rail-to-rail output swing at 1.8V supply?
Yes, the PTLV9054SIRTER achieves rail-to-rail output swing down to 1.8V supply, delivering ≥98% of the supply rail-to-rail range (e.g., 10mV from each rail at 10kΩ load). This capability is verified across –40°C to +125°C and enables direct interfacing with low-voltage ADCs and comparators without level-shifting circuitry.
How does shutdown behavior differ between full and partial modes on the PTLV9054SIRTER?
In full shutdown (SHDN12 = SHDN34 = V−), total quiescent current drops to ≤1µA; in partial shutdown (only one SHDN pin asserted), enable time reduces from 35µs to 10µs because internal bias circuitry remains active. This allows rapid wake-up of selected channels while keeping others powered down - ideal for burst-mode sensor sampling.
Can the PTLV9054SIRTER be used in single-supply configurations with ground-referenced inputs?
Yes, the PTLV9054SIRTER supports true single-supply operation with inputs extending 0.1V below V− (ground) and outputs swinging to within 16mV of V−. Its rail-to-rail input stage accepts common-mode voltages from –0.1V to V+ + 0.1V, enabling direct connection to ground-referenced transducers like strain gauges and current shunts without level-shifting networks.
What is the thermal performance of the PTLV9054SIRTER in its WQFN-16 package?
The PTLV9054SIRTER in RTE (WQFN-16) package has a junction-to-board thermal resistance (RθJB) of 40.5°C/W when the exposed thermal pad is soldered to a 1-in² copper pour. This enables continuous operation at 125°C ambient with ≤150mW total power dissipation - sufficient for four channels driving 10kΩ loads at 5.5V supply.
