The micro-power AS333Q, a single-channel version of the dual-channel AS2333Q op amp, is designed for current sensing and signal detection in a broad range of in-vehicle functions, including airbags, position sensors, vehicle occupant detection sensors, on-board chargers (OBC) and wireless chargers, and battery management systems (BMS).<\/p>\n\n\n\n<p>Automotive designs are increasingly employing brushless DC (BLDC) motors and electronic control units (ECU) for advanced driver assistance systems (ADAS). These require precision op amps for accurate analog signal conditioning. The chopper-stabilised low input offset voltage (VOS = 8\u00b5V) and almost-zero temperature drift (0.02\u00b5V\/\u00b0C) of the AS333Q enable it to maintain high accuracy across the full common-mode input voltage range.<\/p>\n\n\n\n<p>In addition, the device&#8217;s ability to handle beyond-the-rail-to-rail common-mode inputs allows the AS333Q to support both supply and ground-referenced inputs. The extremely low 1.1\u00b5V\/\u221aHz low-frequency noise helps to improve signal-to-noise ratios (SNR), while a low quiescent current of 17\u03bcA (typical) means it can be used in equipment that must continue operating while a vehicle&#8217;s engine is off.<\/p>\n\n\n\n<p>The <strong><a href=\"https:\/\/www.diodes.com\/part\/view\/AS333Q\" target=\"_blank\" rel=\"noreferrer noopener\">AS333Q<\/a><\/strong> is qualified to AEC-Q100 Grade 1, manufactured in IATF 16949 certified facilities.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Diodes Incorporated releases a high-precision operational amplifier (op amp) featuring input offset (VOS) stabilisation for automotive signal conditioning applications.
