Diodes produce precision power amplifiers to automobile specifications

     Two types of precision power amplifiers (op-amps) with different signal frequencies are produced by Diodes to meet the need of advanced signal regulation in modern automobile design. The low noise ratio characteristics of DIODES AS2376Q indicate that they are optimized for high frequency applications such as on-board chargers (OBCs), DC-DC converters, battery management systems (BMS) implementations, pumps, airbags, position sensors, and occupancy detection systems.

     The 5.5MHz bandwidth enables the AS2376Q power amplifier to handle 50kHz signals without significant loss of signal accuracy. Its low input noise density (9.5nV/ OHz) and low frequency noise of 0.8µVpp, coupled with track-to-track output, enhance signal integrity. The AS2376Q features 5μV (typical) compensated voltage and supports a wide dynamic range. Supply voltage acceptance range 2.2V to 5.5V allows for greater design flexibility.

     The AS2333Q power amplifier has a static current of only 12μA on each amplifier channel, so it can be used in systems where it must always be on. Its excellent common-mode rejection ratio (CMRR) over the track-to-rail input range, combined with near-zero drift over time and temperature, provides long-term signal accuracy in wide common-mode rail precision product applications. Its supply voltage of 1.8V to 5.5V enables it to operate on 3.3V and 5V car rails.

     The AS2376Q and AS2333Q are packaged in SO-8. Both comply with AEC-Q100 Grade 1 specification, are manufactured in an IATF 16949 certified facility and support PPAP documentation.
