Description
LM2904QDRG4Q1 is the automotive-grade, dual operational amplifier in TI’s LM2904 family. It contains two independent op-amps in an 8-pin package, designed for low-power, single-supply analog circuits. The Q1 suffix denotes AEC-Q100 (Grade 1) automotive qualification, suitable for harsh environments with an extended temperature range (-40°C to +125°C). The device supports a common-mode input range that includes ground and is not rail-to-rail on the output, so headroom near the supply rails must be accounted for. Typical uses include sensor conditioning, buffering, filtering, and small-signal amplification in automotive and general industrial applications. It is pin-compatible with other LM2904 variants and offers unity-gain stability and low quiescent current for multi-channel designs. For exact electrical characteristics (supply range, input bias, offset, slew rate, output swing), refer to the LM2904QDRG4Q1 datasheet.
Features
LM2904QDRG4Q1 features (concise):
- Automotive-grade, dual general-purpose operational amplifiers (Q1 device)
- Temperature range: -40°C to +125°C
- Wide supply voltage: 3 V to 32 V (single or dual supply)
