Product details
Overview
TLV9152QDGKRQ1 from Texas Instruments is a dual-channel, AEC-Q100 Grade 1 automotive operational amplifier with rail-to-rail input/output, ±125µV offset voltage, 4.5MHz gain-bandwidth, and 21V/µs slew rate. It operates from 2.7V to 16V supply, delivers ±75mA output current, and supports high-side/low-side current sensing in HEV/EV inverters and ADAS sensor signal conditioning.
For engineers reviewing the TLV9152QDGKRQ1 datasheet, TLV9152QDGKRQ1 pinout, TLV9152QDGKRQ1 application, or TLV9152QDGKRQ1 equivalent, key selection criteria include its AEC-Q100 qualification, low 10.8nV/√Hz noise at 1kHz, ±0.3µV/°C drift, 120dB CMRR, and robust EMIRR performance up to 1GHz for safety-critical automotive analog front-ends.
Technical Context
The TLV9152QDGKRQ1 implements a precision bipolar-input op-amp architecture optimized for DC accuracy and wideband AC response. Its dual-channel design shares common power rails (V+ and V−) while maintaining independent input pairs and outputs, enabling matched performance across channels in differential sensing configurations.
It integrates EMI/RFI filtering on both input pins to suppress interference from wireless modules and switching power supplies, and features internal shutdown logic with 3µs disable time and 8µs full-enable time-critical for dynamic power management in infotainment and ADAS subsystems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 4.5MHz - enables stable unity-gain operation up to ~4.5MHz or closed-loop gain of 10 at ~450kHz for sensor amplification. |
| Slew rate | 21V/µs - supports fast transient response in motor control feedback loops and current-sense pulse detection. |
| Input offset voltage | ±125µV (typ) - ensures <1mV error in 8-bit ADC interfaces with 2.5V reference, critical for battery monitoring accuracy. |
| Input voltage noise | 10.8nV/√Hz at 1kHz - preserves SNR in low-level thermistor or strain gauge signal chains. |
| Common-mode rejection | 120dB - rejects >100,000:1 of supply ripple and ground bounce in noisy automotive environments. |
| Supply range | 2.7V to 16V - interoperates with 3.3V microcontrollers and 12V vehicle batteries without level-shifting. |
| Quiescent current | 560µA per amplifier - allows dual-channel operation under 1.2mA total, suitable for always-on ADAS modules. |
Pinout & Package
DGK package: 8-pin VSSOP (3mm × 4.9mm), surface-mount, thermal-enhanced layout for automotive under-hood applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1+ | Noninverting input, channel 1 | Accepts high-impedance sensor signals; rail-to-rail common-mode range supports direct connection to shunt resistors. |
| IN1− | Inverting input, channel 1 | Forms feedback node for precision current-sense amplifiers; matched with IN1+ for low offset drift. |
| OUT1 | Output, channel 1 | Drives 10kΩ loads to within 5mV of rails at 16V supply; ±75mA short-circuit capability handles transient overloads. |
| V− | Negative power supply | Reference for dual-supply operation (±1.35V to ±8V) or ground in single-supply configurations (2.7V–16V). |
| IN2+ | Noninverting input, channel 2 | Independent second channel for redundant sensing or differential pair processing in safety-critical systems. |
| IN2− | Inverting input, channel 2 | Enables matched dual-path signal conditioning with <5µV inter-channel offset mismatch. |
| OUT2 | Output, channel 2 | Provides isolated output drive for secondary feedback loop or diagnostic path without cross-talk. |
| V+ | Positive power supply | Supports wide input transients; internal ESD protection clamps to rails, eliminating need for external TVS diodes. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM7332QMA/NOPB | Higher 24MHz GBW but higher 1.1mV max offset and no AEC-Q100 Grade 1 rating; 1.2mA IQ vs 1.12mA for TLV9152QDGKRQ1. | Used in non-safety-critical infotainment power supplies; not qualified for powertrain or ADAS. | Select when bandwidth >4.5MHz is required and AEC-Q100 Grade 1 is not mandated. |
| OPA2991QDGKRQ1 | Lower 1.2MHz GBW but lower 12nV/√Hz noise and same AEC-Q100 Grade 1; 560µA IQ identical; no integrated EMI filters. | Favored in ultra-low-noise battery monitoring where bandwidth <2MHz suffices and EMI immunity is managed externally. | Select when sub-12nV/√Hz noise dominates over bandwidth and EMI filtering is implemented at board level. |
Compared with LM7332QMA/NOPB and OPA2991QDGKRQ1, TLV9152QDGKRQ1 uniquely balances 4.5MHz bandwidth, ±125µV offset, AEC-Q100 Grade 1 compliance, and on-die EMI filtering-making it optimal for cost-sensitive, safety-aware automotive signal chains where board space and EMI mitigation are constrained.

FAQ
What is the operating temperature range for TLV9152QDGKRQ1?
The TLV9152QDGKRQ1 is qualified per AEC-Q100 Grade 1, supporting continuous operation from −40°C to +125°C ambient temperature. This range is validated for use in engine compartments, battery management systems, and ADAS electronic control units where thermal stress is extreme. All electrical specifications-including offset voltage, CMRR, and slew rate-are guaranteed across this full range.
Does TLV9152QDGKRQ1 support single-supply operation?
Yes, TLV9152QDGKRQ1 supports true single-supply operation from 2.7V to 16V, with rail-to-rail input and output stages enabling full utilization of the supply voltage. When powered from 3.3V or 5V, it maintains ±125µV offset and 120dB CMRR, making it ideal for MCU-interfaced sensor signal chains without negative rails.
What packaging options are available for TLV9152QDGKRQ1?
TLV9152QDGKRQ1 is offered exclusively in the DGK package: an 8-pin VSSOP (3mm × 4.9mm) with exposed thermal pad for enhanced heat dissipation. This package is RoHS-compliant, automotive-grade, and optimized for reflow soldering in high-reliability PCB assemblies used in powertrain and ADAS modules.
How does the EMI rejection feature of TLV9152QDGKRQ1 improve system robustness?
TLV9152QDGKRQ1 integrates EMI/RFI filters on both input pins, delivering >60dB EMIRR at 400MHz and >40dB up to 1GHz. This suppresses interference from cellular bands, Bluetooth, and radar emissions-reducing susceptibility-induced errors in infotainment audio paths and ADAS sensor front-ends without requiring additional board-level filtering components.
Is TLV9152QDGKRQ1 pin-compatible with other devices in the TLV915x-Q1 family?
No-TLV9152QDGKRQ1 (dual-channel, 8-pin DGK) is not pin-compatible with TLV9151-Q1 (single, 5-pin DBV/DCK) or TLV9154-Q1 (quad, 14-pin D/PW/DYY). Pinouts differ across channel counts and packages; PCB layout must be designed specifically for the DGK footprint and dual-channel pin mapping defined in Figure 4-4 and Table 4-3 of the datasheet.
