It features true 16-bit linearity, with differential non-linearity of typically ±0.6 LSB and integral non-linearity of ±0.75 LSB. It has a very high-speed update rate of up to 200 MHz and is ECL compatible. It has an ultrafast settling time of 25 ns to 0.01% and 35 ns to 0.0008%. The SPT5510 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.
