The LTC
®
2604/LTC2614/LTC2624 are quad 16-,14- and
12-bit 2.5V to 5.5V rail-to-rail voltage output DACs in
16-lead narrow SSOP packages. These parts have separate
reference inputs for each DAC. They have built-in high per-
formance output buffers and are guaranteed monotonic.
These parts establish advanced performance standards
for output drive, crosstalk and load regulation in single-
supply, voltage output multiples.
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 and a hardware CLR
function are included.
The LTC2604/LTC2614/LTC2624 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 LTC2604-1/LTC2614-1
/LTC2624-1 to midscale. The voltage outputs stay at mid-
scale until a valid write and update take place.
