数模转换器, RR O/P, 8 bit, SPI, 5V, ± 5V, WSOIC, 20 引脚
The from Products is a quad, serial 8bit digital to analogue DAC with rail to rail outputs in 20 pin WSOIC package. It has four separate reference inputs allowing DAC"s full-scale range to be set independently. Device communicates with microprocessors through a synchronous, full-duplex, 3-wire interface. Data is sent MSB first and can be transmitted in one 4-bit and one 8bit packet or in one 12-bit word. If a 16-bit control word is used, the first four bits are ignored. A 4-wire interface adds a line for LDAC and allows asynchronous updating. The serial clock SCLK synchronizes the data transfer. Data is transmitted and received simultaneously. The interface is compatible with MICROWIRE and SPI/QSPI. All digital inputs and outputs are TTL/CMOS compatible. A buffered data output provides for readback or daisy-chaining of serial devices.
