The LTC^®2600/LTC2610/LTC2620 are octal 16-, 14- and
12-bit, 2.5V-to-5.5V rail-to-rail voltage-output DACs in
16-lead narrow SSOP packages. They have built-in high
performance output buffers and are guaranteed mono-
tonic.
These parts establish new board-density benchmarks for
16- and 14-bit DACs and advance performance standards
for output drive, crosstalk 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 and a hardware CLR
function are included.
The LTC2600/LTC2610/LTC2620 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.
