Product details
Overview
TLV9352QDGKRQ1 from Texas Instruments is a dual-channel, AEC-Q100 Grade 1 qualified automotive operational amplifier with rail-to-rail output, 3.5MHz gain-bandwidth, ±20V max supply, ±60mA output current, and MUX-friendly inputs enabling comparator-mode operation. It serves precision signal conditioning in high-voltage HEV/EV motor control and ADAS current sensing.
For engineers reviewing the TLV9352QDGKRQ1 datasheet, TLV9352QDGKRQ1 pinout, TLV9352QDGKRQ1 application, or TLV9352QDGKRQ1 equivalent, key selection criteria include its ±350µV offset voltage, ±1.5µV/°C drift, 15nV/√Hz noise at 1kHz, robust 110dB CMRR, and EMI rejection up to 94dB at 5GHz - critical for safety-critical automotive analog front-ends.
Technical Context
The TLV9352QDGKRQ1 implements a patented input protection architecture eliminating conventional back-to-back diodes, enabling full 40V differential input swing without distortion or settling delay. Its Class AB output stage delivers ±60mA drive into resistive loads while maintaining rail-to-rail output swing down to 10mV from rails at 40V supply.
It features integrated EMI filtering on both inputs, achieving 90dB EMIRR at 2.4GHz and 94dB at 5GHz - validated per TI's broadband 10MHz–6GHz test methodology. The device operates across –40°C to +125°C with guaranteed performance under 4.5V–40V single-supply or ±2.25V–±20V dual-supply conditions.
Key Specifications

|---|---|
| Gain-bandwidth product | 3.5MHz - supports stable closed-loop operation up to 100kHz with G ≥ 35, suitable for motor phase current feedback loops. |
| Slew rate | 20V/µs - enables fast transient response in overcurrent detection circuits without slew-induced distortion. | Input offset voltage | ±350µV (typ) - ensures ≤0.7mV total error in 200mV full-scale shunt-based current sensing at room temperature. |
| CMRR | 110dB (min) - rejects >100,000:1 common-mode voltage variation, critical for accurate low-side sensing in noisy 48V systems. |
| Supply range | 4.5V to 40V - supports direct connection to 12V, 24V, and 48V automotive battery rails without external regulators. |
| Output current | ±60mA - drives 67Ω loads at ±4V swing or interfaces directly with ADC reference buffers and analog switches. |
| EMIRR @ 5GHz | 94dB - suppresses interference from 5G cellular, Wi-Fi 6E, and radar bands, reducing need for external RF filtering. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM7332QMA/NOPB | Higher 24MHz GBW but higher 1.8mA IQ; no integrated EMI filtering; ±1.5mV offset. | Better for wideband active filters; less suitable for EMI-heavy infotainment PCBs. | Choose LM7332QMA/NOPB when bandwidth >10MHz is required and EMI environment is controlled. |
| TSV912IQDRQ1 | Lower 8MHz GBW; 50µV offset; 125µA IQ; no MUX-friendly inputs or 40V differential rating. | Optimized for ultra-low-power body electronics, not high-voltage motor control. | Choose TSV912IQDRQ1 only for cost-sensitive, low-speed sensor buffering where 40V input tolerance is unnecessary. |
Compared with LM7332QMA/NOPB and TSV912IQDRQ1, TLV9352QDGKRQ1 uniquely balances 3.5MHz bandwidth, 40V differential input capability, and 94dB 5GHz EMIRR - making it the only option qualified for simultaneous use in high-voltage inverter monitoring and RF-dense ADAS domains.

FAQ
What is the maximum differential input voltage specification for TLV9352QDGKRQ1?
The TLV9352QDGKRQ1 supports a maximum differential input voltage of 40V - meaning the voltage difference between IN1+ and IN1– (or IN2+ and IN2–) can reach the full supply rail span. This enables safe use as a comparator in high-side current sensing without external clamping diodes, and is confirmed in Section 5.1 Absolute Maximum Ratings and Section 6.3.1 of the datasheet.
Does TLV9352QDGKRQ1 support single-supply operation?
Yes, TLV9352QDGKRQ1 supports true single-supply operation from 4.5V to 40V. Its input common-mode range extends from (V–) – 0.2V to (V+) – 2V, and rail-to-rail output swings within 10mV of either rail at no load. This allows direct interfacing with 3.3V or 5V ADCs in 12V automotive systems without level-shifting circuitry.
What is the guaranteed operating temperature range for TLV9352QDGKRQ1?
TLV9352QDGKRQ1 is specified for continuous operation from –40°C to +125°C ambient temperature and is AEC-Q100 Grade 1 qualified. Electrical characteristics including offset voltage drift (±1.5µV/°C), CMRR (≥95dB), and quiescent current (≤850µA) are guaranteed across this full range per Section 5.3 Recommended Operating Conditions.
How does the EMI rejection performance of TLV9352QDGKRQ1 compare to standard op-amps?
TLV9352QDGKRQ1 delivers 94dB EMIRR at 5GHz - significantly exceeding typical automotive op-amps (<70dB). This is achieved via integrated input-stage RF filters, validated per TI's 10MHz–6GHz test methodology. At 2.4GHz (Wi-Fi/Bluetooth band), it achieves 90dB rejection, reducing susceptibility to radiated emissions in densely packed ADAS domain controllers.
Can TLV9352QDGKRQ1 be used in open-loop comparator configurations?
Yes, TLV9352QDGKRQ1 is explicitly designed for open-loop comparator use due to its MUX-friendly inputs, which tolerate differential voltages up to 40V and exhibit no phase reversal. The datasheet confirms reliable operation in comparator mode with hysteresis applied externally, and Figure 5-30 shows absence of phase reversal during ±20V input transitions.
