Product details
Overview
PTLV9054IRTER from Texas Instruments is a quad-channel, rail-to-rail input/output operational amplifier optimized for low-voltage, high-speed signal conditioning. It delivers 5MHz unity-gain bandwidth, 15V/µs slew rate, ±0.33mV input offset voltage, 330µA quiescent current per channel, and operates from 1.8V to 6.0V supply. It is used in precision current shunt monitoring and sensor signal conditioning within white goods and HVAC systems.
For engineers reviewing the PTLV9054IRTER datasheet, PTLV9054IRTER pinout, PTLV9054IRTER application, or PTLV9054IRTER equivalent, this page provides verified package mapping (WQFN-16), confirmed quad-channel rail-to-rail I/O behavior, thermal performance data (RθJA = 65.5°C/W), shutdown timing (tON = 35µs full, tOFF = 6µs), and validated alternatives for cost-sensitive, low-power industrial sensing designs.
Technical Context
The PTLV9054IRTER implements a CMOS input stage with 2pA typical input bias current and 15nV/√Hz input voltage noise density at 10kHz, enabling high-impedance photodiode and current-sense amplifier configurations. Its unity-gain stability and internal RFI/EMI filtering support robust operation in electrically noisy environments without external compensation.
It features dual independent shutdown controls (SHDN12 and SHDN34) that reduce total quiescent current to ≤1µA when disabled, while maintaining fast enable/disable transitions (≤35µs enable, ≤6µs disable) and no phase reversal under overdrive - critical for closed-loop motor control feedback paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | Quad - supports simultaneous amplification of four analog signals (e.g., multi-phase motor current, multi-sensor array). |
| Unity-gain bandwidth | 5MHz - enables stable amplification of signals up to ~3MHz with gain ≥2, suitable for active filters and fast-settling ADC drivers. |
| Slew rate | 15V/µs - ensures ≤1µs 0.1% settling for 2V steps, meeting timing requirements in DC motor current loop control. |
| Input offset voltage | ±0.33mV (typ) - contributes ≤0.013% error in 25V full-scale shunt measurements, supporting <1% accuracy current sensing. |
| Quiescent current | 330µA per channel - allows four-channel operation at <1.32mA total, ideal for battery-backed or energy-harvesting sensor nodes. |
| Supply range | 1.8V to 6.0V - interoperates directly with 3.3V and 5V microcontrollers and ADCs without level-shifting. |
| Operating temperature | –40°C to +125°C - qualified for under-hood automotive, industrial motor drives, and appliance control boards. |
Pinout & Package
PTLV9054IRTER is housed in a 16-pin WQFN package (3mm × 3mm, 0.5mm pitch) with exposed thermal pad connected to V– for enhanced power dissipation. The package supports automated optical inspection and high-density PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1+, IN1−, IN2+, IN2−, IN3+, IN3−, IN4+, IN4− | Differential inputs (x4 channels) | CMOS inputs with ±0.1V beyond rails common-mode range; enable direct connection to resistive sensors or shunt resistors. |
| OUT1, OUT2, OUT3, OUT4 | Amplifier outputs | Rail-to-rail swing (≤16mV from rails at 10kΩ load); drives ADC inputs or downstream comparators without level shift. |
| V+, V− | Power supply terminals | Support single-supply (V− = GND) or split-supply operation; V− must connect to exposed thermal pad for thermal integrity. |
| SHDN12, SHDN34 | Shutdown control inputs | Active-high logic: tie to V+ to enable channels 1&2 or 3&4; pull to V− to disable with <1µA total IQSD. |
| NC (pins 6, 7) | No-connect terminals | Not internally bonded - must remain unconnected and unpopulated on PCB to avoid parasitic coupling. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full dynamic range utilization with 1.8V supplies and direct interfacing to 3.3V ADCs without external biasing networks. |
| Internal RFI/EMI filter | Reduces susceptibility to conducted and radiated noise in motor drive and HVAC EMI environments without adding external RC filters. |
| Unity-gain stable | Eliminates need for external compensation components in buffer, gain-of-one, or active filter configurations - reduces BOM count and layout area. |
| Low input bias current (2pA typ) | Minimizes voltage error across high-value feedback or sensor resistors (>1MΩ), preserving accuracy in photodiode transimpedance amplifiers. |
| Capacitive-load drive (150pF) | Stable operation into typical ADC input capacitance or long PCB traces without oscillation, simplifying layout for mixed-signal systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV9064IRTER | Higher 10MHz GBW, 3.5V/µs slew rate, 550µA IQ - trades speed for higher power. | Better for wideband active filters or higher-frequency sensor interfaces; less suitable for ultra-low-power always-on monitoring. | Select TLV9064IRTER when >5MHz closed-loop bandwidth is required and supply current budget allows +220µA/channel. |
| LMV324DR | Lower 1MHz GBW, 1V/µs slew rate, ±3mV VOS, 250µA IQ - older architecture, lower precision. | Acceptable for basic comparator buffers or non-critical signal conditioning where cost is primary constraint. | Choose LMV324DR only for legacy designs or cost-driven consumer appliances where 0.33mV offset and 15V/µs slew are not required. |
Compared with TLV9064IRTER and LMV324DR, PTLV9054IRTER uniquely balances 5MHz bandwidth, 15V/µs slew, and 330µA/channel IQ - making it optimal for next-generation energy-efficient motor control and sensor fusion in industrial white goods.

FAQ
What is the maximum capacitive load the PTLV9054IRTER can drive while remaining stable?
The PTLV9054IRTER maintains stability with up to 150pF capacitive load at unity gain, as confirmed by phase margin >60° in the datasheet. This supports direct connection to typical 10–100pF ADC input capacitances and short PCB traces without external isolation resistors. For loads exceeding 150pF, a series resistor (≥10Ω) between amplifier output and capacitor is recommended to preserve phase margin.
Does the PTLV9054IRTER support single-supply operation?
Yes, the PTLV9054IRTER supports true single-supply operation from 1.8V to 6.0V. Its rail-to-rail input extends 0.1V beyond both supply rails, and rail-to-rail output swings within 16mV of each rail at 10kΩ load - enabling use with ground-referenced sensors and 3.3V microcontrollers without level-shifting circuitry.
How does the shutdown function work on the PTLV9054IRTER?
The PTLV9054IRTER features two independent shutdown pins: SHDN12 controls channels 1 and 2, SHDN34 controls channels 3 and 4. Driving either pin low disables its associated pair, reducing quiescent current to ≤1µA total for all four channels. Enable time is 35µs (full shutdown) or 10µs (partial), and no phase reversal occurs during transition - ensuring safe operation in fault-recovery sequences.
What is the input offset voltage drift over temperature for the PTLV9054IRTER?
The PTLV9054IRTER exhibits ±0.5µV/°C typical input offset voltage drift across –40°C to +125°C, as specified in the electrical characteristics table. This low drift ensures minimal calibration drift in temperature-varying environments such as compressor compartments or HVAC ducts, maintaining <2µV total offset variation over full industrial temperature range.
Can the PTLV9054IRTER be used in photodiode transimpedance amplifier configurations?
Yes, the PTLV9054IRTER is well-suited for photodiode TIA applications due to its 2pA typical input bias current, 15nV/√Hz input voltage noise at 10kHz, unity-gain stability, and rail-to-rail output. These characteristics minimize dark-current error and maximize signal-to-noise ratio - especially critical for low-light detection in proximity or ambient light sensors using the PTLV9054IRTER.
