SPECIFICATIONS
Performance of all channels is identical, exclusive of the interchannel gain mismatch and interchannel phase deviation specifications.
Supply voltages AVDD = AVDD1 = AVDD2 = I/O supply = 3.3 V, digital supply = 1.5 V, unless otherwise noted; temperature = 25°C;
master clock (MCLK) = 12.288 MHz (fS = 48 kHz, 256 × fS mode); input sample rate = 48 kHz; measurement bandwidth = 20 Hz to 20 kHz;
word width = 24 bits; load capacitance (digital output) = 20 pF; load current (digital output) = 2 mA; high level input voltage = 0.7 × IOVDD;
and low level input voltage = 0.3 × IOVDD. All power management registers are set to their default states.
RECORD SIDE PERFORMANCE SPECIFICATIONS
Specifications guaranteed at 25°C (ambient).
