Frequently Asked Questions
What is the maximum common-mode voltage supported by the PINA293A4QDBVRQ1, and why does it matter for high-side sensing?
The PINA293A4QDBVRQ1 supports a maximum common-mode voltage of 110 V, enabling direct measurement of currents on high-voltage rails in automotive battery packs and industrial inverters. This eliminates the need for additional voltage dividers or isolation circuitry, simplifying 48 V and 60 V bus current monitoring designs.
How does the PINA293A4QDBVRQ1 achieve its 160 dB typical common-mode rejection ratio?
The current-feedback architecture of the PINA293A4QDBVRQ1 provides 160 dB typical CMRR, suppressing common-mode noise by a factor exceeding 10 million. This performance level is critical for differential voltage measurements across 0.1 Ohm shunt resistors in noisy automotive powertrain environments operating at up to 110 V.
Is the PINA293A4QDBVRQ1 suitable for automotive-grade designs, and what certification does it carry?
Yes, the PINA293A4QDBVRQ1 is AEC-Q100 qualified for automotive applications, ensuring reliability across the -40°C to 125°C temperature range. Its 5-pin SOT-23 package with a 200 µV maximum offset voltage makes it a cost-effective choice for ADAS sensor front ends and EV battery management units requiring long-term measurement stability.
When would the PINA293A4QDBVRQ1 be selected over a standard instrumentation amplifier for current sensing?
The PINA293A4QDBVRQ1 is preferred when the design must sense currents at common-mode voltages up to 110 V with a minimum-footprint 5-pin SOT-23 solution. Unlike 8-pin instrumentation amplifiers, it integrates the differential gain function in a single compact package, saving 3 or more PCB pins and reducing BOM cost in automotive 48 V mild-hybrid current-sense circuits.
