Part Number: INA1620
We are planing to drive a Head phone as per specification attached with the above circuit. Could you please suggest is the values are mentioned in the schematic able to drive the Head phone.
please suggest what are the changes required…
Part Number: INA1620 Other Parts Discussed in Thread: BUF634A , I see on the datasheet page 9 that the performance of this chip really suffers if the output amplitude is over 1Vrms. To drive certain aviation headsets to necessary high output levels (they…
Part Number: INA1620 Dear mr,
For single power supply INA1620 data-sheet recommend picture below
It mind I should connect my GND to pin5 (VEE of datasheet)
and according picture pin 3 (GND of data-sheet) stay floating.
Am I right?
Part Number: INA1620 Other Parts Discussed in Thread: PCM1796 Hi
I have a question for the application between INA1620 and PCM1796
does it need to add a OPA between the PCM1796 and INA1620?
Part Number: INA1620 Other Parts Discussed in Thread: OPA1642 , OPA1622 Dear TI Support Team,
