Known as AS2376Q, the system is meant for filtering and management, notably in automotive functions – it’s certified AEC-Q100 Grade 1 and has automotive-grade supporting PPAPs.
Each enter and output are rail-to-rail, and operation is over 2.2 to five.5V (950μA max quiescent) and 40°C to +125°C.
Energy provide rejection ratio is usually 5μV/V. “Low voltage operation, low quiescent present and glorious PSRR makes it appropriate for direct battery-powered functions and noise-sensitive functions with noisy low-voltage rails,” in line with the corporate.
When inputs method one volt lower than the constructive rail, a differential pair of nmos transistors takes over from the trimmed pmos pair used in any respect decrease enter voltage. The npn pair doesn’t have precision traits and offset voltage is prone to undergo. Pnp enter offset trimming is optimised for greatest efficiency at half provide voltage.
Packaging is SO-8.
For extra correct automotive amplifier wants, Diodes has simply certified its AS2333 (launched in 2021) to make the AS2333Q twin chopper-stabilised rail-to-rail (out and in) precision op-amp.
Specs of the unique are sometimes 8µV enter offset, 0.02µV/°C drift over time and temperature, 120dB common-mode rejection ratio and 130dB open-loop acquire. Bandwidth is 350kHz, and it sometimes slews at as much as 0.12V/μs. Operation over 1.8V to five.5V (or ±0.9V to ±2.75V) and -40°C to +125°C.
