SPT5400 General 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 compo-nents. Novel circuit topology allows for a guaranteed monotonicity of 13 bits without the need for additional circuitry. The SPT5400 has four separate reference volt-age 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.
