JAJSHU6C January 2011 – August 2019 DRV632
PRODUCTION DATA.
The DRV632 is a DirectPath line-driver amplifier that requires adequate power supply decoupling to ensure that the noise and total harmonic distortion (THD) are low. A good, low equivalent-series-resistance (ESR) ceramic capacitor, typically 1 μF, placed as close as possible to the device VDD lead works best. Placing this decoupling capacitor close to the DRV632 is important for the performance of the amplifier. For filtering lower-frequency noise signals, a 10-μF or greater capacitor placed near the audio power amplifier would also help, but it is not required in most applications because of the high PSRR of this device.
