Differential amp for automotive high-speed signal chains
Output current capability of 100 mA per channel lets it drive multiple ADC inputs or a 50 Ω back-terminated cable directly.
A slew rate of 1500 V/µs means this amplifier can reproduce a 10 V peak-to-peak signal at frequencies up to roughly 48 MHz before slew-rate limiting begins to distort the waveform. For a 2 V peak-to-peak signal typical of modern ADC inputs, the full-power bandwidth extends well past 200 MHz. This headroom matters when the signal chain includes sharp anti-aliasing filter roll-offs or when the amplifier must settle to 12-bit accuracy within one clock cycle of a 50 MSPS or faster ADC. The 850 MHz gain-bandwidth product supports closed-loop gains up to 10 or more while still maintaining useful bandwidth above 60 MHz, which covers most automotive sensor IF and baseband signals.
Automotive temperature range and supply flexibility
The 10.1 mA supply current is a reasonable trade-off for the speed — expect to budget for it in the thermal analysis, especially at 125°C.
Package and landing pattern
The 16-VQFN (3x3 mm) package with exposed thermal pad requires a via-stitched ground pad under the package for adequate thermal dissipation.
For volume production, confirm lead time at the time of your RFQ — the spot market for automotive-grade high-speed amplifiers can tighten during industry-wide allocation cycles.
