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.

The GPY0050A ADC is
Register (SAR) ADC.

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.

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).

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

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 470kΩ.
must be greater than 8ms and resistance of the RVMIC must be less
than 2kΩ.
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)
