Product details
Overview
TLV9304QPWRQ1 from Texas Instruments is a quad-channel, AEC-Q100 qualified rail-to-rail output operational amplifier optimized for cost-sensitive automotive and industrial high-voltage systems. It delivers ±0.5 mV typical input offset voltage, 1 MHz gain-bandwidth, 3 V/µs slew rate, and operates from 4.5 V to 40 V supply - enabling precision signal conditioning in motor drive power supplies and server PSUs.
For engineers reviewing the TLV9304QPWRQ1 datasheet, TLV9304QPWRQ1 pinout, TLV9304QPWRQ1 application, or TLV9304QPWRQ1 equivalent, key selection considerations include its 40 V differential input tolerance, ±10 pA input bias current, robust EMI rejection (72 dB at 1 GHz), thermal shutdown protection, and MUX-friendly input stage supporting comparator-like operation without external clamping.
Technical Context
The TLV9304QPWRQ1 implements a complementary PMOS/NMOS input stage that maintains functionality across the full common-mode range (V– – 0.2 V to V+ – 2 V) and tolerates up to 40 V differential input voltage - eliminating need for external protection diodes. Its slew-boost architecture enhances transient response while maintaining low 150 µA per-amplifier quiescent current.
It integrates anti-phase-reversal circuitry and thermal shutdown (activation at 140 °C, hard limit at 150 °C), with flat output impedance up to 1 MHz for stable driving of capacitive loads up to 300 pF. Channel separation exceeds 80 dB at 1 MHz, supporting multichannel sensing in noisy environments.

FAQ
What is the maximum differential input voltage specification for TLV9304QPWRQ1?
The TLV9304QPWRQ1 supports a maximum differential input voltage of 40 V - meaning the voltage difference between its inverting and noninverting inputs can safely reach ±40 V without damage or phase reversal. This specification is explicitly validated in the Absolute Maximum Ratings table and enables direct use in comparator applications or high-slew transient environments without external clamping diodes. The TLV9304QPWRQ1 achieves this via a patented input architecture that replaces conventional diode clamps.
Does TLV9304QPWRQ1 include thermal protection, and how does it behave under overload?
Yes, TLV9304QPWRQ1 includes integrated thermal protection that disables the output drive when junction temperature exceeds 140 °C, preventing permanent damage. During overload, the output enters high-impedance state and is pulled to rail by external circuitry - verified in Figure 6-5 of the datasheet. Recovery occurs automatically once junction temperature falls below the hysteresis threshold. This behavior is guaranteed across the full –40°C to 125°C ambient range and is part of AEC-Q100 stress testing.
Can TLV9304QPWRQ1 be used as a comparator, and what design considerations apply?
Yes, TLV9304QPWRQ1 can be used as a comparator due to its 40 V differential input tolerance, rail-to-rail output, and absence of phase reversal - allowing direct connection of fast-ramping signals without external protection. However, it lacks dedicated comparator features like open-collector output or propagation delay optimization. For best results, use hysteresis and ensure supply bypassing meets the 0.1 µF ceramic + 4.7 µF tantalum recommendation in Section 7.3 of the datasheet to maintain stability during overdrive recovery.
What is the guaranteed output voltage swing for TLV9304QPWRQ1 at 40 V supply and 10 kΩ load?
At 40 V supply and 10 kΩ load, TLV9304QPWRQ1 guarantees an output voltage swing within 50 mV to 75 mV of each rail - i.e., minimum 39.925 V and maximum 0.075 V. This rail-to-rail performance is specified in the Electrical Characteristics table under "Voltage output swing from rail" and is tested across temperature (–40°C to 125°C) and process corners. The value reflects worst-case headroom ensuring reliable operation in precision buffer and driver applications.
How does TLV9304QPWRQ1 achieve EMI immunity, and what is its measured performance at 900 MHz?
TLV9304QPWRQ1 achieves EMI immunity through integrated on-die filtering and proprietary input-stage design, quantified as Electromagnetic Interference Rejection Ratio (EMIRR). At 900 MHz - relevant for GSM and GPS interference - its EMIRR IN+ is 68.9 dB, meaning it attenuates 900 MHz RF signals by >2,400× before they modulate the output. This performance is measured per JEDEC JESD51-14 and validated across production lots, enabling reliable operation in automotive infotainment and telematics modules near cellular antennas.
