Diodes Incorporated introduces high-precision automotive-compliant Op Amp with input offset stabilization

August 4, 2023 /SemiMedia/ — Diodes Integrated just lately launched a precision operational amplifier (op amp) with enter offset (VOS) stabilization for automotive sign conditioning functions. The micropower AS333Q, a single-channel model of the dual-channel AS2333Q op amp, is designed for present sensing and sign detection in a broad vary of in-vehicle features, together with airbags, place sensors, car occupant detection sensors, on-board chargers (OBC) and wi-fi chargers, and battery administration techniques (BMS).

Automotive designs are more and more using brushless DC (BLDC) motors and digital management items (ECU) for superior driver help techniques (ADAS). These require precision op amps for correct analog sign conditioning. The chopper-stabilized low enter offset voltage (VOS = 8µV) and almost-zero temperature drift (0.02µV/°C) of the AS333Q allow it to take care of excessive accuracy throughout the total common-mode enter voltage vary.

As well as, the machine’s potential to deal with beyond-the-rail-to-rail common-mode inputs permits the AS333Q to assist each provide and ground-referenced inputs. The extraordinarily low 1.1µV/√Hz low-frequency noise helps to enhance signal-to-noise ratios (SNR), whereas a low quiescent present of 17μA (typical) means it may be utilized in gear that should proceed working whereas a car’s engine is off.

The AS333Q is certified to AEC-Q100 Grade 1, manufactured in IATF 16949 licensed services, and is PPAP succesful. It's obtainable within the SOT25 bundle at $0.82 in 1,000 piece portions. For extra info, please go to https://www.diodes.com/half/AS333Q.
