AK2331

DAC Type 8-bit 4-channel

Electronic Volume

Features

• 8-bit 4 channels of built-in multiplication D/A converters

• Support for external one-path, internal three-path D/A converter reference voltages

• Built-in buffer amplifier with low distortion (-60dB typ.) and rail-to-rail operation

• Support for 3V control and 5V operation because of the three-wire serial system with

separate power supplies

• Operating voltage range: 2.6 to 5.5V

• Operating temperature range: -40 to +85°C

• Package： 16-pin QFNJ (3.0mm x 3.0mm x 0.70mm, 0.5-mm pitch)

Overview

The AK2331 is an electronic volume into which 8 bit 4 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 VIN3. 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 VOUT3 pins through the buffer amplifier by bypassing

the D/A converter or the buffer amplifier is powered down.

A 16-pin small and low-profile QFNJ package (3.0mm square x 0.70mm height) is employed to

achieve high-density packaging.
