Overview
The AK2330 is an electronic volume into which 8 bit 8 channels of multiplication D/A converters are
integrated on a single chip.
The reference voltage of the D/A converter can be selected from one external path (VREF pin level)
and internal three paths (VSS, AVDD, AVDD/2) for each channel and it can be used as a normal D/A
converter or an electronic volume that attenuates signals from input pins VIN0 to VIN7. A buffer
amplifier is incorporated as the subsequent stage of the D/A converter, which provides rail-to-rail
output and a signal with a distortion of -60dB.
In operational setting, the three-wire serial system, which synchronizes serial input (SDATA)
consisting of a 4-bit address and 8-bit data with the CSN and SCLK signals, is adopted, a power
supply (DVDD) is provided separately from the D/A converter, and 3V serial control and 5V D/A
converter operation are enabled. In addition, settings can be made so that the AVDD/2 level, which
was generated internally, is output to VOUT0 to VOUT7 pins through the buffer amplifier by bypassing
the D/A converter or the buffer amplifier is powered down.
A 24-pin small and low-profile QFNJ package (4.0mm square x 0.75mm height) is employed to
achieve high-density packaging.
