Product details
Overview
TLV9162QPWRQ1 from Texas Instruments is a dual-channel, AEC-Q100 Grade 1 automotive operational amplifier with rail-to-rail input/output, ±210 µV typical offset voltage, 11 MHz gain-bandwidth product, and 33 V/µs slew rate - deployed in high-side current sensing, ADAS sensor signal conditioning, and HEV/EV motor control feedback loops.
For engineers reviewing the TLV9162QPWRQ1 datasheet, TLV9162QPWRQ1 pinout, TLV9162QPWRQ1 application, or TLV9162QPWRQ1 equivalent, this page delivers verified electrical specs, package-validated pin functions, automotive-grade thermal and ESD ratings, and real-world implementation context for precision analog signal chains in safety-critical vehicle systems.
Technical Context
The TLV9162QPWRQ1 implements a patented MUX-friendly front-end architecture enabling full 16 V differential input voltage tolerance without clamping diodes - eliminating transient-induced settling delays in multiplexed sensor arrays. Its dual-channel layout supports independent high-precision signal paths with matched AC/DC performance across channels.
It integrates robust EMI rejection circuitry (EMIRR > 80 dB at 100 MHz), operates from 2.7 V to 16 V single supply (±1.35 V to ±8 V dual), and maintains 110 dB CMRR over –40°C to +125°C - critical for noise-immune current sensing in powertrain and battery management subsystems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 16 V single supply (±1.35 V to ±8 V dual) - supports wide automotive battery transients and low-voltage microcontroller interfaces. |
| Gain-Bandwidth Product | 11 MHz - enables stable closed-loop operation up to ~1 MHz with G = 10, suitable for fast current loop compensation. |
| Slew Rate | 33 V/µs - ensures <0.7 µs 0.1% settling for 10 V step, critical for accurate pulse-width modulated (PWM) current measurement. |
| Input Offset Voltage | ±0.21 mV typical (±1.2 mV max over temperature) - reduces DC error in shunt-based current sensing below 0.5% full-scale. |
| Input Bias Current | ±10 pA - minimizes voltage drop across high-impedance sensor bridges and reference dividers. |
| Common-Mode Rejection | 110 dB at 16 V supply - suppresses battery rail noise in high-side sensing configurations where VCM approaches VBAT. |
| ESD Rating (HBM) | ±2500 V - meets AEC-Q100 Grade 1 requirements for robustness in manufacturing and field environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision automotive op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSV912AQDRQ1 | Lower GBW (8 MHz), higher offset (±1.5 mV), same AEC-Q100 Grade 1 rating and TSSOP-8 package. | Less suitable for >500 kHz closed-loop bandwidths or sub-1% current sensing accuracy. | Preferred when cost sensitivity outweighs need for 11 MHz bandwidth or ultra-low offset. |
| LM7332QMA/NOPB | Higher quiescent current (3.6 mA/ch), wider supply (±16 V), but lower CMRR (95 dB) and no AEC-Q100 certification. | Not qualified for automotive safety-critical systems; requires external qualification effort. | Only for non-safety automotive prototyping or industrial equivalents where AEC-Q100 is not mandated. |
Compared with TSV912AQDRQ1 and LM7332QMA/NOPB, the TLV9162QPWRQ1 delivers superior DC precision (±0.21 mV offset), higher speed (11 MHz vs 8 MHz), and guaranteed automotive qualification - making it the optimal choice for production ADAS, powertrain, and EV subsystems requiring zero requalification risk.

FAQ
What is the maximum differential input voltage specification for TLV9162QPWRQ1?
The TLV9162QPWRQ1 supports a maximum differential input voltage of 16 V - enabled by its patented MUX-friendly input architecture that eliminates conventional clamping diodes. This allows direct connection to fast-ramping signals in multiplexed battery monitoring or high-side current sensing without distortion or extended settling time. The specification is validated across –40°C to +125°C and applies to both channels of TLV9162QPWRQ1.
Does TLV9162QPWRQ1 support single-supply operation?
Yes, TLV9162QPWRQ1 operates from a single supply ranging from 2.7 V to 16 V, with rail-to-rail input and output capability. It functions correctly with V– tied to ground and V+ at 3.3 V, 5 V, or 12 V - making it compatible with standard automotive microcontrollers and sensor interfaces. Input common-mode range extends from V– to V+, and output swings within 25 mV of each rail at 16 V supply with 10 kΩ load.
What is the thermal resistance (RθJA) of TLV9162QPWRQ1 in the PW (TSSOP-8) package?
The TLV9162QPWRQ1 in the PW (TSSOP-8) package has a junction-to-ambient thermal resistance (RθJA) of 159.1 °C/W, as specified in the official datasheet's thermal information table. This value assumes standard JEDEC PCB mounting conditions (2-layer board, 1 in² copper). For high-power-density automotive layouts, derating must account for ambient temperature up to +125°C and ensure junction temperature remains ≤150°C under worst-case load.
How does TLV9162QPWRQ1 achieve EMI immunity?
TLV9162QPWRQ1 integrates on-die electromagnetic interference rejection (EMIRR) filtering, achieving >80 dB rejection at 100 MHz. This is implemented through dedicated internal filtering networks at input stages - distinct from external RC filters - and is validated per ISO 11452-4. The feature directly mitigates noise coupling from wireless modules, switching regulators, and ignition systems, preserving signal integrity in ADAS camera power supplies and radar signal chains without added BOM cost.
Is TLV9162QPWRQ1 pin-compatible with other devices in the TLV916x-Q1 family?
No - TLV9162QPWRQ1 (dual-channel, TSSOP-8) is not pin-compatible with TLV9161-Q1 (single, SOT-23/SC70) or TLV9164-Q1 (quad, SOIC/TSSOP-14). Pin count, spacing, and functional mapping differ across variants. While all share identical electrical specifications and AEC-Q100 qualification, PCB layout must be tailored to the specific channel count and package. The TLV9162QPWRQ1 pinout is fixed per Table 4-2 in the datasheet and validated for PW package only.
