LM4890: Gain Setting/Pairing with Door Bell Chip

Part Number: LM4890
Other Parts Discussed in Thread: LM4991, TPA6211A1, LM4871

Hi Sir/Madam,

Is LM4890 suitable to pair with door bell chip, RATO RT0302? The gain setting is about 200 but the sound is weak from speaker output.

RATO RT0302 Datasheet: 

Currently the door bell is designed with MCU as main control, controlling door bell chip, RATO RT0302, output to speaker to perform door bell sound. Any other TI solution suggested for door bell function?

Hope to hear from you soon. Thanks.
