Product details
Overview
TLV9152SIRUGR from Texas Instruments is a dual-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 product, 20 V/µs slew rate, and operates from 2.7 V to 16 V supply. It is used in high-side current sensing and factory automation analog front-ends where low noise (10.5 nV/√Hz) and robust EMI rejection are critical.
For engineers reviewing the TLV9152SIRUGR datasheet, TLV9152SIRUGR pinout, TLV9152SIRUGR application, or TLV9152SIRUGR equivalent, key selection criteria include dual-channel shutdown control, X2QFN-10 package thermal performance (RθJA = 142.3°C/W), rail-to-rail output swing within 5 mV of rails at no load, and verified operation across –40°C to 125°C.
Technical Context
The TLV9152SIRUGR implements a precision bipolar-input op amp architecture with integrated EMI/RFI filters on both inputs, enabling stable operation in noisy industrial environments. Its dual independent shutdown pins (SHDN1, SHDN2) support per-channel power gating without affecting the other amplifier.
It features two matched high-performance amplifiers sharing common V+ and V– supplies, with separate noninverting/inverting inputs and outputs per channel. The X2QFN-10 package includes an exposed thermal pad connected to V–, supporting efficient heat dissipation in space-constrained PCB layouts.
Key Specifications

Pinout & Package
The TLV9152SIRUGR is housed in a 10-pin X2QFN package (1.5 mm × 1.5 mm, 0.4 mm height) with exposed thermal pad connected to V–. This compact, thermally enhanced package supports high-density routing and improved power dissipation in automated assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| V– | Negative supply | Reference node for both amplifiers and thermal pad connection point |
| SHDN1 | Digital input | Active-low enable for Channel A; logic low = amplifier active, high = high-Z output |
| SHDN2 | Digital input | Active-low enable for Channel B; independent control avoids cross-talk during sequencing |

| IN2– | Analog input | Inverting input for Channel B; matched bias current (±10 pA) minimizes offset in high-Z sources |
| OUT2 | Analog output | Channel B output; drives ≥75 mA short-circuit current and sustains 1000 pF capacitive loads |
| V+ | Positive supply | Single shared positive rail for both amplifiers; supports wide supply headroom |
| OUT1 | Analog output | Channel A output; fully independent from OUT2, enabling dual-path signal processing |
| IN1– | Analog input | Inverting input for Channel A; differential input voltage range extends to ±(V+ – V–) + 0.2 V |
| IN1+ | Analog input | Noninverting input for Channel A; EMI-filtered pin improves RF immunity in wireless-adjacent systems |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel 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 pins | Used in metrology-grade instruments requiring sub-µV offset stability; lacks per-channel power control | Select when ultra-low offset dominates over power flexibility and cost sensitivity |
| AD8602ARMZ | Higher offset (±200 µV), lower noise (8 nV/√Hz), no EMI filtering, SOIC-8 only | Deployed in legacy industrial controllers with board-level EMI mitigation; incompatible with X2QFN-10 layout | Select when footprint compatibility with existing SOIC-8 designs is mandatory and EMI immunity is externally managed |
Compared with OPA2182IDR and AD8602ARMZ, TLV9152SIRUGR uniquely balances low offset, integrated EMI hardening, dual independent shutdown, and X2QFN-10 thermal efficiency-making it optimal for next-generation compact, noise-immune industrial signal chains.

FAQ
What is the maximum operating temperature range for TLV9152SIRUGR?
The TLV9152SIRUGR is specified for continuous operation from –40°C to +125°C ambient temperature. This extended range is validated across all electrical parameters in the datasheet, including offset voltage drift (±0.3 µV/°C), CMRR (≥99 dB at 125°C), and quiescent current (≤750 µA per amplifier). The X2QFN-10 package's thermal metrics support reliable junction temperature control under these conditions.
Does TLV9152SIRUGR support true rail-to-rail input and output operation?
Yes, TLV9152SIRUGR supports rail-to-rail input common-mode voltage from (V–) – 0.1 V to (V+) + 0.1 V and rail-to-rail output swing within 5 mV of each rail at no load (VS = 16 V). This enables full utilization of supply voltage headroom in single-supply 3.3-V or 5-V systems and direct interfacing with ADCs having rail-referenced inputs.
How does the EMI/RFI filtering on TLV9152SIRUGR inputs improve system robustness?
The TLV9152SIRUGR integrates on-die EMI/RFI filters on both IN+ and IN– pins, significantly attenuating high-frequency interference (e.g., GSM bursts, switching regulator noise) before it reaches the input stage. Measured EMIRR exceeds 80 dB at 900 MHz, reducing need for external RC filters and preventing rectification-induced DC offset errors in sensitive analog front-ends.
What is the function of the exposed thermal pad on the TLV9152SIRUGR X2QFN-10 package?
The exposed thermal pad on TLV9152SIRUGR must be soldered to a PCB copper pour connected to the V– net. It reduces thermal resistance (RθJB = 68.5°C/W) and improves power dissipation capability-critical for maintaining junction temperature below 150°C during sustained 75-mA output current or high ambient operation.
Can TLV9152SIRUGR drive heavy capacitive loads without instability?
Yes, TLV9152SIRUGR is characterized to drive up to 1000 pF capacitive loads while maintaining ≥60° phase margin and monotonic step response. Its internal compensation and 20 V/µs slew rate prevent ringing or oscillation in configurations such as active filters, cable drivers, or ADC input buffers with long traces or large sampling capacitors.
