Microphone Amplifier, ETX=1
Open loop gain
Gain bandwidth product
Input noise voltage,
BW = 300 Hz to 3.4 kHz,
psophometrically weighted
Compressor, ETX = 1; 470 nF from CTC to GND (VSS)
Gain reference level = G.R.L.
(gain = 0 dB)
Gain versus input signal level
(“gain tracking”)
Attack time
= +25°C, VRF = VAF = RFOVB = 3.6V, all bits set to “0”, unless otherwise specified. Test circuit, see
Test Conditions
DAIN
DACO, without load
(CMOS-output –> full swing)
DACO, without load
(CMOS-output –> full swing)
DACO
Decrease VBAT until internal switch
between VBAT and VDD becomes high
ohmic (“off”)
Increase VBAT until internal switch
between VBAT and VDD becomes low
ohmic (“on”)
Difference between on and off threshold
DA[6:0] = 127, RBAT = 1
DA[6:0] = 27, RBAT = 1
DA[6:0] = 127, RBAT = 0
DA[6:0] = 0, RBAT = 0
VCOIN = 20 dB less than G.R.L.
VCOIN = 40 dB less than G.R.L.
VCOIN = 50 dB less than G.R.L.
VCOIN = 60 dB less than G.R.L
VCOIN = step 31.6 mV –> 126 mV,
(-30 dBV –> –18 dBV)
measure time after step, when output
voltage has 1.5 times of final value
