Another applications engineer has had this same request before. the charge pump frequency cannot be modified,
However the device DRV603 is pin-for-pin compatible and has a higher typical charge pump frequency
Other Parts Discussed in Thread: PCM1789 , DIR9001 , PCM1794A , DRV603 , OPA1612 , PCM1794 Hello,
is there anywhere explanation how to interface those three devices?
I was reading something( ) about interfacing DIR9001 and DRV603 with PCM1789, but PCM1789 seems…
Part Number: DRV603 On page 10 of DRV603 datasheet at table 1 are values for various gains listed. The values in the second row for a gain of 1.5 / 2.5 are wrong! They should be 18k and 27k instead of 15k and 30k!
the third row (33k and 68k) are 2.1, but…
Other Parts Discussed in Thread: DRV632 , DRV603 The DRV632 has a !MUTE (active low) pin which puts the output in a low-impedance state when muted. The DRV632 datasheet specs Zo, the output impedance when muted, as 110mOhms. The DRV603 has an ENable input…
Other Parts Discussed in Thread: DRV603 Hello~
According to DRV603 datasheet, T A value of "ORDERING INFORMATION" and T A value of "RECOMMENDED OPERATING CONDITIONS" have different range.
I think one of those is typo.

As you know well, DRV603 and DRV632 is provide the TINA Library individually .
My question is as below.
The characteristics of these two IC 's TINA Library is whether the same or not.
Sorry to so…
Other Parts Discussed in Thread: DRV632EVM , DRV603EVM Hello~
According to DRV603EVM & DRV632EVM, it is using the 16V voltage rating for the Charge Pump Flying CAP.
Is the 16V voltage rating mendatory??
If the VDD is 3.3V, Can I use 10V or 6.3V rating instead…
You should take a look at DRV603. It is pin to pin compatible and same functionality:

Could you please share a block diagram for better understanding of your application?
You mean you need to amplify a reference voltage from 1.5V to 3V? You need to drive this from the codec for sync purposes? I'm curious why not to use a different…
