Datasheet 10 channel in QFN Small Package 10 bit D/A Converters BU22210MUV General Description Key Specifications BU22210MUV includes 10 channels D/A converters Operating Supply Voltage Range: 2.7V to 5.5V which is high performance 10bit R-2R-type. It is most Current Consumption: 1.2mA(Typ) suitable for applications which have many adjustment Differential Non Linearity Error: 0.5LSB items, because it is small size and has many D/A Integral Non Linearity Error: 2.0LSB converter channels. Output Current Capability: 1.0mA Input is serial data transfer system with the DI, CLK and Data Transfer Frequency: 10MHz(Max) CSB terminal, and output is DO terminal enabling a Operating Temperature Range: -20C to +85C cascade connection. A built-in Initial-Zero-Hold function ensures that the output voltage of all channels are Low during power up, so that it is able to reduce parts for measure against Package W(Typ) x D(Typ) x H(Max) malfunction. And wide supply voltage range from 2.7V - VQFN016V3030 3.00mm x 3.00mm x 1.00mm 5.5V has flexibility to specification change. Features Built-in 10-channel 10bit D/A converters. Built-in Rail-to-rail output buffer. 3-wire serial interface (16 bit data). Cascade Connection is available. Built-in Initial-Zero-Hold function. QFN Small package (0.5mm pitch). Applications The various types of consumer (ex. Printer, DSC and more).
