GENERAL 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.
