DESCRIPTION
16-/14-/12-Bit Rail-to-Rail
DACs in 10-Lead DFN
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 performance
output buffers and are guaranteed monotonic.
10-lead DFN package. They have built-in high performance
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, volt-
age-output DACs.
16- and 14-bit DACs and advance performance standards
for output drive and load regulation in single-supply, volt-
age-output DACs.
The parts use a simple SPI/MICROWIRE compatible 3-wire
serial interface which can be operated at clock rates up to
50MHz. Daisy-chain capability, hardware CLR and asyn-
chronous DAC update (LDAC) pins are included.

chronous 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 until a valid write and
update take place. The power-on reset circuit resets the
LTC2601-1/LTC2611-1/LTC2621-1 to midscale. The volt-
age outputs stay at midscale until a valid write and update
take place.
