Frequently Asked Questions
What common-mode voltage range does PINA293A3QDBVRQ1 support, and how does it compare to standard 5 V amplifiers?
The PINA293A3QDBVRQ1 supports a common-mode voltage range up to 110 V, far exceeding the typical 5 V or 26 V range of standard op-amps. This makes it suitable for 48 V automotive bus and high-voltage battery stack monitoring where rail voltages exceed 12 V to 60 V.
Which automotive system designs benefit most from PINA293A3QDBVRQ1's 140 dB CMRR specification?
Designs requiring accurate differential current measurement in noisy 48 V or 400 V EV battery systems benefit most. The 140 dB minimum CMRR ensures less than 10 µV of error per 1000 V of common-mode noise, enabling precise 1 mΩ shunt resistor current sensing across 8 to 16 cell battery modules.
Is PINA293A3QDBVRQ1 compliant with automotive reliability standards?
Yes, the PINA293A3QDBVRQ1 is AEC-Q100 qualified and designed for automotive applications with a temperature range of -40°C to 125°C. It meets the reliability requirements for Grade 1 automotive ICs used in under-hood environments and safety-critical power management circuits.
How does the SOT-23-5 package of PINA293A3QDBVRQ1 affect PCB layout in current sensing designs?
The SOT-23-5 package measures approximately 2.9 mm × 1.6 mm, allowing integration of current sense amplification in space-constrained designs. With a 5-pin layout, designers can place the amplifier within 5 mm of a 1 mΩ to 10 mΩ shunt resistor to minimize parasitic resistance and maintain measurement accuracy below 0.1%.
