The LM2904QPWRG4Q1 from Texas Instruments is an automotive-grade dual general-purpose operational amplifier integrating two independent bipolar amplifier channels. The LM2904-Q1 supports a 3V to 26V total supply range, making it suitable for automotive sensor conditioning, voltage monitoring, active filtering and general analog control applications.
A key feature is its common-mode input range extending to the negative supply rail, enabling direct sensing of signals close to ground in single-supply systems. At 25°C, the typical upper common-mode limit is approximately V+ − 1.5V, while the specified full-temperature operating limit is V+ − 2V.
The LM2904-Q1 provides a typical 0.7MHz gain-bandwidth product and 0.3V/µs slew rate. Typical input voltage-noise density is 40nV/√Hz at 1kHz, typical CMRR is 80dB, and channel separation is approximately 120dB.
DC characteristics include approximately ±3mV typical input offset voltage and ±7mV maximum at 25°C. Typical quiescent current is 350µA per amplifier. Typical output-current capability is approximately 30mA source and 20mA sink, with typical short-circuit current of approximately ±40mA.
The device is AEC-Q100 Grade 1 qualified for automotive applications and operates across -40°C to +125°C. TI also identifies the LM2904-Q1 family as Functional Safety-Capable, with documentation available to support functional-safety system design.
The exact LM2904QPWRG4Q1 ordering option uses an 8-pin TSSOP (PW) package measuring approximately 3 × 6.4mm. TI’s current packaging information lists it as Active Production, with NiPdAu lead finish, MSL Level 1 at 260°C, RoHS compliance and 2,000-piece large tape-and-reel packaging.
