5. FUNCTIONAL DECRIPTIONS  
5.1. SPI Serial Interface  
The GPY0050A supports SPI Mode 0 and Mode 3 waveforms.  
When CSN is low, the DIN is latched on the rising of DCLK and  
DOUT is shifted out on the falling edge of DCLK. If CSN is high,  
it will disable SPI interface, set DOUT pin in high impedance state  
and maintain the register data. When the GPY0050A is power on,  
the power on reset (POR) will set all registers to default value.

The first command bit, the ‘S’ bit, must always be high and  
indicate the start of command input. The second bit, ‘R/W’ bit,  
controls Read or Write register. The next two bits (CMM_ADDR)  
select register address. The last 4 bits (CMD_DATA) is the data  
that will be written to register.

GPY0050A  
5.2. Analog-to-Digital Converter  
The GPY0050A ADC is  
Register (SAR) ADC.  
a
12-bit Successive Approximation  
FS = Full Scale Voltage = VDD  
1LSB=VDD / ( 212 – 1 ) = VDD / 4095 Î 12bit Mode  
1LSB=VDD / ( 210 – 1 ) = VDD / 1023 Î 10bit Mode  
The ADC provides 12-bit 10-bit  
/
conversion mode operation and 8 analog input channels (see  
Figure 12). The converter digitizes the input signal form 0V to  
full-scale voltage (see Figure 13). The internal applied voltage  
reference value determines the full-scale input voltage range.  
11…111  
11…110  
11…101  
11…100  
1LSB  
The voltage reference of the GPY0050A is fixed to VDD  
.
User can operate the ADC in continuing or discontinuing  
conversion mode by CSN pin. In continuing conversion mode,  
CSN pin is always kept low. The GPY0050A requires 16-DCLKs  
per conversion (see Figure 5 & 6).  
00…011  
00…010  
00…001  
00…000  
Continuous Mode Sampling Rate = fDCLK / 16  
In discontinuing conversion mode, the ADC sampling and holding  
signal (ADC_S/H) can be controlled by CSN pin. The ADC will  
hold analog value on CSN falling edge, and need 24-DCLKs to  
finish conversion (see Figure 7 & 8). In discontinuing conversion  
mode, user can easily control sampling and holding time by CSN  
pin.

The ADC_CHSEL register is used to select ADC input channel  
(IN0 ~ IN7). The IN5 ~ IN7 pins are shared with microphone  
preamplifier block. Therefore, the MUX cannot be set to IN5 ~  
IN7 channel, when microphone preamplifier is enabled.

5.3. Microphone Preamplifier  
The GPY0050A Microphone Preamplifier consists of several  
distinct circuits: microphone bias switch (M1), first stage amplifier  
(MIC Preamplifier), second stage amplifier (OP-Amplifier) and  
AGC control circuitry, shown in Figure 14.  
set to maximum value (Gain=15 @ VDD=3.3V).  
The second stage amplifier consists of R1, R2 and OPA. The  
default gain is (1+R2/R1) = 41. Users can make a series  
resistance reduce the gain of second stage amplifier.  
When register EN_MIC is set to ‘1’, the internal switch M1 will be  
turned on and VMIC pin will be shorted to VDD. In order to  
reduce power noise, recommend RC time constant of (RVMIC×CVMIC  
Gain of second stage amplifier = 1 + R2 / (R1+ROP1)  
)
The AGC Control senses OPO pin output waveform. When “VOPO  
> VDD – 0.3” or “VOPO < 0.3”, the AGC will pump CAGC capacitor.  
The AGC voltage will rise to reduce gain of first stage amplifier  
until “VOPO < VDD – 0.3” or “VOPO > 0.3”. In order to avoid the  
noise generated by the AGC Control, recommend capacitance of  
the CAGC must be greater than 2.2uF and resistance of the RAGC  
must be greater than 470k.  
must be greater than 8ms and resistance of the RVMIC must be less  
than 2k.  
The first stage microphone amplifier (MIC Preamplifier) is  
difference input preamplifier. The gain can be varied by the AGC.  
When AGC pin voltage rises, the MIC preamplifier will reduce the  
gain. If AGC function is turned off (EN_AGC=’0’), the gain will be

7. APPLICATION CIRCUIT  
The demo board circuit of the GPY0050A is shown in Figure 15. User can easily evaluate GPY0050A performance by the demo board.  
In order to reduce power noise from other device, suggest connecting Power and GND Line from power source, adding power filter for the  
GPY0050A and don’t share power and ground line with other devices. (See Figure 16 & 17)
