MAX5580-MAX5585中文资料美信数据手册PDF规格书

General Description

The MAX5580–MAX5585 quad, 12-/10-/8-bit, voltag eoutput, digital-to-analog converters (DACs) offer buffered outputs and a 3µs maximum settling time at the 12-bit level. The DACs operate from a +2.7V to +5.25V analog supply and a separate +1.8V to +5.25V digital supply. The 20MHz, 3-wire, serial interface is compatible with SPI™, QSPI™, MICROWIRE™, and digital signal processor (DSP) protocol applications. Multiple devices can share a common serial interface in directaccess or daisy-chained configuration.
