LTC2601/LTC2611/LTC2621
16-/14-/12-Bit Rail-to-Rail
DACs in 10-Lead DFN
2601f
The LTC
2601/LTC2611/LTC2621 are single 16-, 14-
and 12-bit,
2.5V-to-5.5V rail-to-rail voltage output DACs
in a 10-lead DFN package. They have built-in high perfor-
mance output buffers and are guaranteed monotonic.
These parts establish new board-density benchmarks for
16- and 14-bit DACs and advance performance standards
for output drive, and load regulation in single-supply,
voltage-output multiples.
The parts use a simple SPI/MICROWIRE
TM
compatible
3-wire serial interface which can be operated at clock rates
up to 50MHz. Daisy-chain capability, hardware CLR and
asynchronous DAC update (LDAC) pins are included.
The LTC2601/LTC2611/LTC2621 incorporate a power-on
reset circuit. During power-up, the voltage outputs rise
less than 10mV above zero scale; and after power-up, they
stay at zero scale until a valid write and update take place.
