Description

The SPT5420 contains eight 13-bit digital-to-analog CMOS converters designed primarily for automatic test equipment applications. It uses novel circuit topology to convert the 13-bit digital inputs into output voltages which are proportionate to the applied reference voltages. Each
DAC's full-scale output voltage and output voltage offset are adjustable with analog inputs (RGND, V_REFB, V_REFT).

The SPT5420 operates over an industrial temperature range of 40 °C to +85 °C and is available in a 10  x 10 mm,44-lead metric quad flat pack (MQFP) plastic package.
