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, VREFB, VREFT). 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. BLOCK DIAGRAM |
