Микросхема AD7302BNZ, 8-битный ЦАП с параллельным входом [DIP-20]

Характеристики

AD7302BNZ, 8-битный ЦАП с параллельным входом [DIP-20]The AD7302BNZ is a dual 8-bit voltage out Digital-to-analog Converter (DAC) operates from a single 2.7 to 5.5V supply. Its on-chip precision output buffers allow the DAC outputs to swing rail to rail. The AD7302 has a parallel microprocessor and DSP-compatible interface with high speed registers and double buffered interface logic. Data is loaded to the registers on the rising edge of CS or WR and the A/B pin selects either DAC A or DAC B. Reference selection for AD7302 can be either an internal reference derived from the VDD or an external reference applied at the REFIN pin. The DAC can be simultaneously updated using the asynchronous LDAC input and can be cleared by using the asynchronous CLR input. The low power consumption of this part makes it ideally suited to portable battery operated equipment. The power consumption is less than 10mW at 3.3V, reducing to 3µW in power-down mode.
