CORRECTING and REPLACING Automotive-Compliant Precision Op-Amps from Diodes Incorporated Offer Wide Dynamic Range and Low Noise Operation


Second paragraph, second sentence of release dated September 30, 2022, should read: "Its low input noise density (9.5nV/?Hz) and 0.8ÁVpp low frequency noise..." (instead of 7.5 nV/?Hz, and adding the word low before frequency).

The updated release reads:

AUTOMOTIVE-COMPLIANT PRECISION OP-AMPS FROM DIODES INCORPORATED OFFER WIDE DYNAMIC RANGE AND LOW NOISE OPERATION

Diodes Incorporated (Diodes) (Nasdaq: DIOD) is addressing the need for advanced signal conditioning in modern automotive designs by introducing two precision operational amplifiers (op-amps) aimed at different signal frequency scenarios. The low signal-to-noise ratio characteristics of the DIODEStm AS2376Q mean it is optimized for high frequency usage, such as in on-board chargers (OBCs), DC-DC converters, battery management system (BMS) implementations, pumps, airbags, position sensors and occupancy detection systems. The minimal quiescent current exhibited by DIODEStm AS2333Q, launched in August, make it highly suited to addressing functions that continue even when the vehicle is inactive.

A 5.5MHz bandwidth enables the AS2376Q op-amp to handle 50kHz signals without significant loss of signal accuracy. Its low input noise density (9.5nV/?Hz) and 0.8ÁVpp low frequency noise, coupled with rail-rail output, result in enhanced signal integrity. With 5?V (typical) offset voltage, the AS2376Q supports a wide dynamic range. Supply voltages from 2.2V to 5.5V are accepted, enabling greater design-in flexibility.

The AS2333Q op-amp has a quiescent current of just 12?A on each amplifier channel that allows it to be used in systems that have to remain live at all times. Excellent common-mode rejection ratio (CMRR) across its rail-rail input range coupled with near-zero drift over time and temperature provide long-term signal accuracy in wide common-mode rail precision applications. Its 1.8V to 5.5V supply voltage enables it to operate from 3.3V and 5V automotive rails.

The AS2376Q and AS2333Q are supplied in the SO-8 package. These devices are available at unit pricings of $0.93 and $1.56 respectively in 1000 piece quantities. Both are qualified to AEC-Q100 Grade 1, are manufactured in IATF 16949 certified facilities, and support PPAP documentation.
