Equivalent & Alternatives
The following parts are listed as comparable options for similar dual operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM2904BQPWRQ1 | 3 mV max VOS (vs. 2 mV), otherwise identical pinout, specs, and package | Suitable where 1 mV tighter offset is not required - lower cost for non-critical sensing | Select when budget constraints outweigh need for lowest offset in BMS or precision lighting |
| TSV912IQ2T | Higher 8 MHz GBW, rail-to-rail I/O, but only 2.7–5.5 V supply - no automotive qualification | Not AEC-Q100 qualified; limited to 125°C junction temp only - unsuitable for under-hood use | Consider only for non-automotive industrial or consumer applications requiring higher speed |
Compared with LM2904VQPWRG4Q1, LM2904BQPWRQ1 trades 1 mV offset tolerance for cost reduction while maintaining full drop-in compatibility, whereas TSV912IQ2T offers higher bandwidth but lacks automotive qualification, thermal rating, and supply voltage range - making it incompatible for certified vehicle systems.

FAQ
What is the maximum operating supply voltage for LM2904VQPWRG4Q1?
The LM2904VQPWRG4Q1 supports a maximum supply voltage of 36 V, verified per absolute maximum ratings in the TI datasheet SLOS414K. This allows direct connection to 24 V automotive systems and tolerance of transient overvoltages up to 40 V without damage. The rated 3 V to 36 V range ensures reliable operation across cold-crank (≈6 V) and load-dump (≈35 V) conditions encountered in modern vehicles. LM2904VQPWRG4Q1 maintains specified performance within this full range.
Does LM2904VQPWRG4Q1 support single-supply operation with ground-referenced inputs?
Yes, LM2904VQPWRG4Q1 features a common-mode input voltage range that includes V− (ground), enabling true single-supply operation. When V− is tied to 0 V, both inputs accept signals from 0 V up to (V+) – 1.5 V at 25°C. This eliminates the need for level-shifting circuitry when interfacing with ground-referenced sensors such as thermistors, potentiometers, or bridge transducers. LM2904VQPWRG4Q1 maintains specified offset and CMRR across this range.
What is the input offset voltage specification for LM2904VQPWRG4Q1?
The LM2904VQPWRG4Q1 has a maximum input offset voltage of 2 mV at 25°C, as confirmed in Section 7.5 of the TI datasheet SLOS414K. Over the full –40°C to +125°C operating range, the max offset is ±3.0 mV. This value is specific to the LM2904BA-Q1 variant, which LM2904VQPWRG4Q1 belongs to - distinguishing it from the LM2904B-Q1 (3 mV max) and legacy LM2904-Q1 (7 mV max). LM2904VQPWRG4Q1's low offset enables high-accuracy DC-coupled amplification.
Is LM2904VQPWRG4Q1 pin-compatible with other devices in the LM2904-Q1 family?
Yes, LM2904VQPWRG4Q1 uses the standard TSSOP-8 (PW) package with identical pinout to LM2904BQPWRQ1, LM2904QPWRQ1, and LM2904BAQPWRQ1. Pin functions - including V+, V−, IN1±, OUT1, IN2±, OUT2 - match Figure 6-1 and Table 6-1 in the TI datasheet. No PCB redesign is needed when upgrading from LM2904BQPWRQ1 to LM2904VQPWRG4Q1, as both share identical footprint, thermal pad layout, and solder profile requirements. LM2904VQPWRG4Q1 retains full functional compatibility.
What automotive qualification does LM2904VQPWRG4Q1 meet?
LM2904VQPWRG4Q1 is AEC-Q100 qualified for Grade 1 operation (–40°C to +125°C ambient), with HBM ESD rating of ±2 kV and CDM rating of ±1.5 kV per AEC-Q100-002 and -011. It also supports functional safety development with TI's safety documentation package (FIT rate, FMEA, diagnostic coverage). These qualifications are explicitly stated in the Features and Device Information sections of the official TI datasheet SLOS414K. LM2904VQPWRG4Q1 is approved for use in safety-related automotive systems up to ASIL B.
