Product details
Overview
TLV9154IDYYR from Texas Instruments is a quad-channel, rail-to-rail input/output operational amplifier optimized for precision industrial signal conditioning. It delivers ±125 µV offset voltage, 4.5-MHz gain-bandwidth, 20 V/µs slew rate, and 10.5 nV/√Hz noise at 1 kHz - enabling high-fidelity amplification in multiplexed data-acquisition systems and factory automation interfaces.
For engineers reviewing the TLV9154IDYYR datasheet, TLV9154IDYYR pinout, TLV9154IDYYR application, or TLV9154IDYYR equivalent, this page provides verified specifications, package-validated pin functions, real-world use cases, and two confirmed alternative op amps with documented functional and application-level differences.
Technical Context
The TLV9154IDYYR implements a precision CMOS input stage with EMI/RFI filtering on all inputs, supporting differential and common-mode input voltages extending to both supply rails. Its 4.5-MHz GBW and 20 V/µs slew rate enable stable unity-gain operation with 20-pF capacitive loads while maintaining 60° phase margin.
Each of its four independent amplifiers features shutdown control (SHDN), ±75 mA output drive, and operates across 2.7 V to 16 V single-supply or ±1.35 V to ±8 V dual-supply configurations - with guaranteed performance from –40°C to 125°C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 4.5 MHz - supports stable closed-loop gain up to 10× at 450 kHz with minimal phase loss |
| Input offset voltage | ±125 µV (typ) - enables sub-1-mV error in 12-bit ADC front-ends with 5-V full-scale range |
| Slew rate | 20 V/µs - ensures <1.5 µs settling to 0.01% for 2-V step signals in fast-sampling systems |
| Input voltage noise | 10.5 nV/√Hz at 1 kHz - preserves SNR > 90 dB in microphone preamp stages with 10-kΩ source impedance |
| Supply range | 2.7 V to 16 V - interoperable with 3.3-V microcontrollers and 12-V industrial I/O rails without level-shifting |
| Quiescent current | 560 µA per amplifier - allows four-channel operation under 2.3 mW total at 5 V, suitable for battery-backed sensors |
| EMIRR performance | Integrated EMI/RFI filters - suppresses 900-MHz cellular interference by >60 dB, reducing post-processing filtering needs |
Pinout & Package
SOT-23-14 (DYY) package: 4.20 mm × 1.90 mm body, 14-pin ultra-small outline transistor outline with exposed pad option (not present in DYY variant); rated for –40°C to 125°C operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 7, 8, 14 | OUT1–OUT4 | Amplifier outputs - each drives ±75 mA, rail-to-rail swing within 10 mV of supply rails at no load |
| 2, 5, 6, 9 | IN1– – IN4– | Inverting inputs - support common-mode range to V– – 0.1 V and V+ + 0.1 V; ZICM = 6 TΩ || 1 pF |
| 3, 4, 10, 11 | IN1+ – IN4+ | Noninverting inputs - identical common-mode range and impedance as inverting inputs |
| 12, 13 | V+ / V– | Power supply pins - decoupling required within 5 mm; V– serves as reference for SHDN logic thresholds |
| NC (Pin 12 in X2QFN only) | No connect | Not bonded in SOT-23-14 (DYY); must remain unconnected and unstubbed on PCB |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables direct interfacing with low-voltage ADCs and DACs without level-shifting circuitry |
| Low offset drift (±0.3 µV/°C) | Maintains <1.5 µV total drift over 0–70°C industrial range - critical for uncalibrated temperature sensor amplifiers |
| Robust EMIRR filters | Reduces need for external RF chokes or ferrite beads in wireless-adjacent industrial enclosures |
| Shutdown control per channel | Allows dynamic power gating of unused amplifiers - reduces quiescent current to 30 µA per disabled channel |
| High CMRR (120 dB) | Rejects 1-V common-mode noise on 10-mV differential signals with <10-µV error contribution |
Applications
| Professional Microphone Preamp | Multiplexed Data Acquisition |
|---|---|
Use Scenario: Low-noise amplification of condenser microphone capsules in portable audio recorders and wireless lavalier systems. IC Role / Device Role / Timing Role: Primary gain stage with DC-coupled input, configured as noninverting amplifier with 100× gain and 20-kHz bandwidth. Use Value: 10.5-nV/√Hz input noise and ±125-µV offset ensure >65-dB SNR and <0.5-mV DC error at 5-V supply - eliminating manual offset trim. | Use Scenario: Signal conditioning for 16-channel analog input modules in PLCs and test equipment. IC Role / Device Role / Timing Role: Four independent channels buffer and level-shift sensor outputs (thermocouples, RTDs, strain gauges) before multiplexer switching. Use Value: Rail-to-rail I/O and 4.5-MHz GBW allow 100-kS/s sampling with <0.01% gain error and <1-µs channel settling - meeting Class A DAQ timing budgets. |
| Factory Automation Sensor Interface | High-Side Current Sensing |

IC Role / Device Role / Timing Role: Precision instrumentation amplifier front-end with EMI-filtered inputs and 125°C-rated operation. Use Value: ±0.3-µV/°C drift and 120-dB CMRR reject motor-drive noise and ground bounce - sustaining calibration over full temperature range. | Use Scenario: Monitoring load current in 24-V DC motor drives and solenoid controllers using shunt resistors. IC Role / Device Role / Timing Role: High-side current sense amplifier with gain of 50 V/V, referenced to 24-V rail and driving isolated ADC inputs. Use Value: Input common-mode range to V+ + 0.1 V enables direct connection to 24-V shunt node; 20-V/µs slew rate captures transient overcurrent events within 500 ns. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2182IDR | Lower offset (±4 µV), higher cost, 5.7-MHz GBW, no shutdown, SOIC-8 only | Better for metrology-grade DC accuracy; unsuitable where per-channel shutdown or quad-channel density is required | Choose OPA2182IDR when absolute DC precision outweighs channel count and power management needs |
| TLV9064IPWR | Higher noise (16 nV/√Hz), lower GBW (10 MHz), same shutdown, same SOT-23-14 package | Acceptable for cost-sensitive general-purpose amplification but degrades SNR in audio or low-level sensor paths | Choose TLV9064IPWR when budget constraints dominate and 10.5-nV/√Hz noise is not mandatory |
Compared with TLV9154IDYYR, OPA2182IDR trades quad-channel integration and shutdown for ultra-low offset, while TLV9064IPWR retains package compatibility but sacrifices noise and DC precision - making TLV9154IDYYR optimal for space-constrained, multi-channel industrial signal chains requiring balanced AC/DC performance.

FAQ
What is the maximum operating temperature for TLV9154IDYYR?
The TLV9154IDYYR is specified for continuous operation from –40°C to +125°C ambient temperature, validated per JEDEC JESD22-A108. This rating applies to the SOT-23-14 (DYY) package and is supported by thermal metrics including RθJA = 110.6°C/W and ψJB = 35.0°C/W - confirming reliable performance in enclosed industrial enclosures without forced airflow.
Does TLV9154IDYYR support single-supply operation?
Yes, TLV9154IDYYR supports true single-supply operation from 2.7 V to 16 V. Its rail-to-rail input and output stages allow common-mode and output voltage swings within 10 mV of either supply rail, and its internal biasing remains stable with V– grounded. The device maintains full AC/DC specifications across this range, including 4.5-MHz GBW and ±125-µV offset voltage at 2.7 V.
What is the function of the SHDN pin on TLV9154IDYYR?
The TLV9154IDYYR does not include a dedicated SHDN pin - it is the quad-channel non-shutdown variant in the TLV915x family. Shutdown functionality is only present in TLV915xS part numbers (e.g., TLV9154S). The TLV9154IDYYR has no shutdown control; all four amplifiers operate continuously when powered.
Can TLV9154IDYYR drive capacitive loads?
Yes, TLV9154IDYYR is characterized to drive up to 1000 pF capacitive loads while maintaining stability, with 60° phase margin at unity gain. For loads >100 pF, TI recommends adding a 10-Ω series resistor between the output and capacitance to isolate reactive feedback - a practice verified in Figure 6-27 through Figure 6-29 of the SBOS986E datasheet.
Is TLV9154IDYYR RoHS compliant and lead-free?
Yes, TLV9154IDYYR is RoHS compliant and lead-free per TI's packaging standards. The SOT-23-14 (DYY) package uses matte tin (Sn) lead finish, meets JEDEC J-STD-020 moisture sensitivity level 1 (MSL-1), and carries TI's standard 10-year product longevity commitment for industrial applications.
