OPERATION The LTC2640 is a family of single voltage-output DACs in 8-lead ThinSOT packages. Each DAC can operate rail- to-rail using an external reference, or with its full-scale voltage set by an integrated reference. 12 combinations of accuracy (12-, 10-, ...

LTC2640 OPERATION Serial Interface The CS/LD input is level triggered. When this input is taken low, it acts as a chip-select signal, enabling the SDI and SCK buffers and the input shift register. Data (SDI input) is transferred at the ...

OPERATION Power-Down Mode For power-constrained applications, the LTC2640’s power- down mode can be used to reduce the supply current whenever the DAC output is not needed. When in power- down, the buffer amplifi er, bias circuit, and reference circuit are ...
