DRV632: Low Cost OPAxxxx Solution for Line Driver

Part Number: DRV632
Other Parts Discussed in Thread: OPA322, OPA134

Hi,

Could you please give us your advice since we would like to replace DRV632 with the low cost audio opamp(OPAxxxx series) ?
We are consider to apply OPAxxxx to the multi-feedback(MFB) with differential input which the pwm modulator outputs are input.
The requirements are shown as below.

<Requirements>
 - VCC : 3.0 ~ 3.6V
 - diferential input signal : pwm modulator pulse
 - load impedance : 5kΩ ~ 10kΩ
 - without mute pin
 - without shutdown pin
 - unity gain stable
 - low cost
 - filter topology : 2nd-order active low pass filter(multi-feedback)

Best regards,
Kato
