Resistor Ladders Aid In D/A And A/D Conversions

Claimed to be ideal for D/A and A/D conversions, the R/2R thin-film resistor ladder networks are available in values from 10 ohms to 1 Megaohm. The networks have a TCR of ±100 ppm/°C and an absolute tolerance of ±2%. The standard configuration of the devices is as an eight-bit ladder network with a ±1/2LSB accuracy. The series is available in pin counts of 8, 14, 16, 20 and 24 and body styles that include SOIC, QSOP and 0.6, 0.5 and 0.4 die packs. Custom designs and values are also available.
