Part Number: PCM1770 Hi，
I want to use PCM1770 to drive headphone directly. I need to drive 1w 8ohm and add op amp. Is there any relevant mature circuit to share for reference ?
Thanks！
Part Number: PCM1770 Other Parts Discussed in Thread: PCM1774 Dear all
I want to use PCM1770 device connect with audio power amplifier for speakers, in the datasheet of PCM1770, the Basic Connection Diagram as below picture, can I use others caps insteal…
Part Number: PCM1770 Dear all
Can it connect with audio PA for speaker ? Or it only connect with Headphone ? I find when connect with PA, the signal on HOUTR or HOUTL pins will be zero.
Part Number: PCM1770 Other Parts Discussed in Thread: TPA3128D2 , , OPA333 Hi,
I have attached a schematic for my design of a sound system using the PCM1770 and TPA3128D2 . The OpAmps circuit you see in the schematic is a Single Supply Single-Ended…
Other Parts Discussed in Thread: PCM1770 Hi,
I am looking at the PCM1770 Stereo DAC with Headphone Amplifier and am having trouble interpreting the datasheet. From my understanding the power consumption of the chip is 6.5mW. So the total consumption…

My customer asks:
As I was reading through the PCM1770 data sheet about output
power it says:
stereo output power is about 13 mWrms and mono is about
26 mWrms for the headphone output. Is the stereo…
Part Number: TPA3100D2 Other Parts Discussed in Thread: PCM1770 , TPA3130D2 , TPA3129D2 , TPA3123D2 Tool/software: We need speaker amplifier with synchro input for PWM switching frequency 781.25 kHz or 390.625 kHz.
TPA3100D2 includes SYNC input, but…
Your response on the filter design is very helpful. Regarding the PCM1770, you mentioned this has a line driver for differential output. Does this mean that I would control the volume of the sound coming from the speaker by controlling the attenuation…
