Part Number: TPA6166A2
Hi Sirs, I got a problem with TPA6166 microphone amplifier measurement which needs BU's help: (1) Only 250mV full scale input on SLEEVE with CTIA configuration. (2) Lower Output LEVEL on MOUTN then our expection. 1. Test condition…
Part Number: TPA6166A2 Hi Sirs, We got -3dB corner frequency at 30Hz with TPA6166 EVM. We tried to short the lowpass filter on R1 but not improved. Is it doable to make flat frequency response from 20Hz to 20kHz with the microphone amp of the TPA6166? Would…
Part Number: TPA6166A2 Hi Sirs, The TPA6166 datasheet specifies the requirement of 22ohm@100MHz of ferrite bead on microphone input path. The "120 1.2A (such as BLM18BB220SN1)" on the datasheet seems problematic. Would you please review the specification…
Part Number: TPA6166A2 Hi Sirs, We need product line to correct the mistakes of reference design of the TPA6166 datasheet page 23 released on January, 2015. 1. Update CPVDD bypass caps from 1.0pF to 1.0uF 2. Update CPVSS bypass caps from 1.0pF to 1.0uF 3…
Part Number: TPA6166A2 Dear Ti team,
Would you let me know INL/INR allowed input range?
In my understanding, that is from CPVSS to CPVDD.
Since Charge pump circuit is implemented, that is CPVSS(-1.8V) to CPVDD(1.8V) when VDD=1.8V??
BR,
Matsuda
Part Number: TPA6166A2 Hi Sirs, Would you pls advise two specifications of the TPA6166? 1. Common mode input range of the TPA6166's microphone input signal on RING2 and SLEEVE. 2. Maximum output voltage of MOUTN
With 24dB gain and 2.6V mic bias, I got…
Part Number: TPA6166A2 Other Parts Discussed in Thread: TLV320AIC3204 , TS3A227E Dear TI support team,
Does it comply with the Android Wired Handset V1.1 specification?
Thanks.

Part Number: TPA6166A2
Hi Sirs, As title, would you pls advise CFG to bring up the TPA6166 to assert IRQ# on headsets insertion event but masked headphones event as the chart below? With Current configuration (0x04=0x0c). I got IRQ# pulses (status changes…
Part Number: TPA6166A2
Hi Sirs, As title, is the TPA6166's IRQ# an open drain or push-pull signal? We assume that it is an open drain signal because the datasheet does not specify VOH(min) and there is a 100kR pull up to 1.8V on its EVM. However, there…
Part Number: TPA6166A2 Dear TI team,
Are MOUTP/MOUTN biased by TPA6166A2?
As per our observation, it seems not biased.
I am wondering if I should insert capacitor between our audio codec mic input and TPA6166A2 MOUTP/N outout.
If not biased by TPA6166A2…
