Second paragraph, second sentence of release dated September 30, 2022, should read: "Its low input noise density (9.5nV/√Hz) and 0.8µVpp 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 DIODES™ 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 DIODES™ 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 0.8µVpp low frequency noise, coupled with rail-rail output, result in enhanced signal integrity. With 5μV (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 12μA 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.
