LTC2606/LTC2616/LTC2626

26061626f

16-/14-/12-Bit Rail-to-Rail DACs

The LTC

and 12-bit, 2.7V-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 DACs.

LTC2606/LTC2616/LTC2626 operate in both the standard

mode (clock rate of 100kHz) and the fast mode (clock rate

of 400kHz). An asynchronous DAC update pin (LDAC) is

also included.

The LTC2606/LTC2616/LTC2626 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. The

power-on reset circuit resets the LTC2606-1/LTC2616-1/

LTC2626-1 to midscale. The voltage outputs stay at

midscale until a valid write and update take place.
