SPT5400中文资料仙童半导体数据手册PDF规格书

DESCRIPTION

The SPT5400 has eight 13-bit voltage output digital-to-analog converters on one chip. It operates from ±5 V power supplies and has maximum voltage output swings of up to ±4.5 V without the addition of external components. Novel circuit topology allows for a guaranteed monotonicity of 13 bits without the need for additional circuitry. The SPT5400 has four separate reference voltage inputs, one for each pair of DACs. Four separate analog ground pins allow for separate offset voltages for each DAC pair. Each DAC can be asynchronously loaded through a common 13-bit bus into a double-buffered set of latches. All logic inputs are TTL/CMOS compatible.

The SPT5400 is available in a 44-lead PLCC package over the commercial temperature range of 0 °C to +70 °C.
