Product details
Overview
TLV9152QPWRQ1 from Texas Instruments is a dual-channel, AEC-Q100 Grade 1 automotive operational amplifier with rail-to-rail input and output, ±125 µV typical offset voltage, 4.5 MHz gain-bandwidth product, and 21 V/µs slew rate. It operates from 2.7 V to 16 V supply, delivers ±75 mA output current, and supports high-side/low-side current sensing in HEV/EV inverters and ADAS sensor signal conditioning.
For engineers reviewing the TLV9152QPWRQ1 datasheet, TLV9152QPWRQ1 pinout, TLV9152QPWRQ1 application, or TLV9152QPWRQ1 equivalent, key selection criteria include its AEC-Q100 qualification, low 10.8 nV/√Hz noise at 1 kHz, robust EMIRR performance up to 1 GHz, and dual-channel TSSOP-8 packaging for space-constrained automotive PCB layouts.
Technical Context
The TLV9152QPWRQ1 implements a precision CMOS input stage with EMI/RFI filtering on both inputs, enabling stable operation in noisy automotive environments. Its dual-channel architecture shares a common power-supply domain (V+ and V−) while maintaining channel separation >100 dB at DC and >70 dB at 1 MHz.
It features internal biasing optimized for rail-to-rail swing across the full temperature range (–40°C to +125°C), with ±0.3 µV/°C offset drift and 120 dB common-mode rejection-critical for differential sensing in body electronics and powertrain current monitoring.
Key Specifications

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSV912AQDRQ1 | Lower 1.6 MHz GBW, higher 1.1 mV max offset, no integrated EMI filters | Better suited for cost-sensitive, lower-bandwidth body electronics-not recommended for radar or inverter sensing | Select when budget constraints outweigh need for 4.5 MHz bandwidth and EMI robustness |

FAQ
What is the operating temperature range for TLV9152QPWRQ1?
The TLV9152QPWRQ1 is qualified per AEC-Q100 Grade 1 with guaranteed operation from –40°C to +125°C ambient temperature. This range is validated across all electrical parameters including offset voltage, CMRR, and output drive capability-ensuring reliability in engine control units and battery management systems.
Does TLV9152QPWRQ1 support single-supply operation?
Yes, TLV9152QPWRQ1 supports true single-supply operation from 2.7 V to 16 V. Its rail-to-rail input and output stages allow full-swing signal handling even at 2.7 V, making it ideal for 3.3 V microcontroller-based automotive modules without external level-shifting circuitry.
What is the maximum capacitive load TLV9152QPWRQ1 can drive stably?
The TLV9152QPWRQ1 is specified to drive up to 1000 pF capacitive load while maintaining ≥60° phase margin. For loads exceeding 1000 pF, external isolation resistance (e.g., 50 Ω in series with output) restores stability-verified in Figure 5-29 of the datasheet.
How does the EMI rejection feature of TLV9152QPWRQ1 improve system robustness?
TLV9152QPWRQ1 integrates on-chip EMI/RFI filters on both inputs, achieving ≥60 dB rejection at 400 MHz and >40 dB up to 1 GHz. This eliminates susceptibility to cellular, Wi-Fi, and Bluetooth interference-reducing need for board-level shielding in telematics and infotainment ECUs.
Is TLV9152QPWRQ1 pin-compatible with other dual-channel automotive op amps?
No, TLV9152QPWRQ1 uses a standard TSSOP-8 pinout (IN1+, IN1−, OUT1, V−, IN2+, IN2−, OUT2, V+) but is not pin-compatible with TSZ122 or LMV932QDRQ1 due to differing pin assignments for power and inputs. PCB layout must follow TI's recommended footprint for PW package.
