DAC08 Summary of contents
Page 1
... In many applications, the outputs can be directly converted to voltage without the need for an external op amp. All DAC08 series models guarantee full 8-bit monotonicity, and nonlineari- ties as tight as ±0.1% over the entire operating temperature range are available. Device performance is essentially unchanged over the ± ...

... APPLICATION INFORMATION REFERENCE AMPLIFIER SETUP The DAC08 is a multiplying D/A converter in which the output current is the product of a digital number and the input reference current. The reference current may be fixed or may vary from nearly zero to 4.0 mA. The full-scale output current is a linear function of the reference current and is given by ...

... useful feature of the DAC08 design is that supply current is constant and independent of input logic states. This is useful in cryptographic applications and further reduces the size of the power supply bypass capacitors. TEMPERATURE PERFORMANCE The nonlinearity and monotonicity specifications of the DAC08 are guaranteed to apply over the entire rated operating tempera- ture range ...

... This code change does not require the normal 6.2 time constants to settle to within ±0.2% of the final value, and thus settling time is observed at lower values of I DAC08 switching transients or “glitches” are very low and can be further reduced by small capacitive loads at the output ...
