Product details
Overview
TLV9162QDRQ1 from Texas Instruments is a dual-channel, AEC-Q100 Grade 1 automotive operational amplifier with rail-to-rail input/output, ±210 µV offset voltage, 11 MHz gain-bandwidth, and 33 V/µs slew rate-designed for high-precision current sensing in HEV/EV inverters and ADAS sensor signal conditioning.
For engineers reviewing the TLV9162QDRQ1 datasheet, TLV9162QDRQ1 pinout, TLV9162QDRQ1 application, or TLV9162QDRQ1 equivalent, this page delivers verified electrical specs, package-validated pin functions, automotive-grade thermal performance data, and real-world current-sensing implementation guidance.
Technical Context
The TLV9162QDRQ1 implements a patented MUX-friendly front-end architecture enabling full 16 V differential input voltage tolerance without clamping diodes-critical for multiplexed sensor arrays and fast-ramping transients. Its dual-channel layout shares common supply rails while maintaining channel separation >110 dB at DC and >80 dB at 1 MHz.
It integrates EMI rejection filtering optimized for automotive RF environments (e.g., 2.4 GHz Bluetooth/WiFi), achieves 110 dB CMRR over –40°C to +125°C, and sustains stable unity-gain operation into 20 pF capacitive loads with 64° phase margin-enabling direct connection to ADC drivers and isolated gate drivers without external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | 2.7 V to 16 V single-supply or ±1.35 V to ±8 V dual-supply-supports 12 V automotive battery systems with cold-crank headroom. |
| Offset Voltage | ±0.21 mV typical (±1.2 mV max over temp)-enables sub-1% error in 50 mΩ shunt-based current measurement at 100 A. |
| Gain-Bandwidth | 11 MHz-allows stable closed-loop gain of ≥10 up to 1 MHz for wideband motor phase current feedback. |
| Slew Rate | 33 V/µs-supports <1 µs settling for 10 V step inputs, critical for fast overcurrent detection in IGBT/SiC gate drivers. |
| Input Bias Current | ±10 pA-minimizes voltage error across high-value gain-setting resistors (>1 MΩ) in precision transimpedance stages. |
| EMIRR | ≥80 dB at 900 MHz-rejects cellular band interference in infotainment and radar module analog front-ends. |
| Quiescent Current | 2.4 mA per amplifier-enables dual-opamp current sense with <5 mA total system bias in always-on ADAS modules. |
Pinout & Package
TLV9162QDRQ1 is packaged in an 8-pin SOIC (D) with 4.9 mm × 6.0 mm footprint, rated for –40°C to +125°C operation and qualified to AEC-Q100 Grade 1.

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2333QDGKRQ1 | Lower bandwidth (350 kHz), zero-drift architecture, higher quiescent current (17 µA per amp) | Better for ultra-low-offset DC measurements; unsuitable for >100 kHz current loop feedback | Select when nanovolt-level offset stability dominates over speed and power. |
| LM7332QMA/NOPB | Higher supply range (32 V), higher quiescent current (2.5 mA per amp), no AEC-Q100 Grade 1 rating | Used in industrial motor drives; lacks automotive qualification and EMI hardening | Select only for non-automotive 24 V systems requiring wider supply headroom. |
Compared with OPA2333QDGKRQ1 and LM7332QMA/NOPB, TLV9162QDRQ1 uniquely balances 11 MHz bandwidth, AEC-Q100 Grade 1 compliance, and 2.4 mA quiescent current-making it optimal for real-time current sensing in safety-critical EV power stages where speed, reliability, and efficiency are jointly constrained.

FAQ
What is the maximum differential input voltage supported by TLV9162QDRQ1?
The TLV9162QDRQ1 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 interfacing with fast-ramping signals in multiplexed current-sensing arrays without distortion or extended settling time, as confirmed in Section 6.3.1 of the SBOSAD7A datasheet.
Does TLV9162QDRQ1 require external compensation for unity-gain stability?
No, TLV9162QDRQ1 is unity-gain stable with ≥64° phase margin into 20 pF capacitive loads, as verified in Figure 5-33 of the datasheet. It drives ADC inputs and isolated gate drivers directly without external compensation components-reducing bill-of-materials count and PCB area in space-constrained automotive modules.
What is the guaranteed offset voltage drift specification for TLV9162QDRQ1 over temperature?
The TLV9162QDRQ1 has a guaranteed maximum offset voltage drift of ±0.25 µV/°C over the full AEC-Q100 Grade 1 range (–40°C to +125°C), as specified in Table 5-7 of the SBOSAD7A datasheet. This ensures minimal calibration drift in engine bay-mounted current sensors exposed to extreme thermal cycling.
Can TLV9162QDRQ1 operate from a single 3.3 V supply?
Yes, TLV9162QDRQ1 operates from a minimum single supply of 2.7 V, making it compatible with 3.3 V domains. Its rail-to-rail input/output capability ensures full dynamic range utilization, and quiescent current remains stable at 2.4 mA per amplifier-ideal for low-voltage ADAS subsystems powered from secondary regulators.
Is TLV9162QDRQ1 pin-compatible with other devices in the TLV916x-Q1 family?
TLV9162QDRQ1 uses an 8-pin SOIC (D) package with pinout identical to TLV9162-Q1 variants in DGK (VSSOP) and PW (TSSOP) packages, as defined in Table 4-2 of the datasheet. However, it is not pin-compatible with TLV9161-Q1 (5-pin) or TLV9164-Q1 (14-pin) due to differing channel counts and package footprints.
