DESCRIPTION
Octal 16-/14-/12-Bit
Rail-to-Rail DACs in 16-Lead SSOP
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 and 20-lead 4mm × 5mm QFN
packages. They have built-in high performance output
buffers and are guaranteed monotonic.

packages. 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, crosstalk and load regulation in single-supply,
voltage-output multiples.

output drive, crosstalk and load regulation in single-supply,

The parts use a simple SPI/MICROWIRE compatible 3-wire
serial interface which can be operated at clock rates up
to 50MHz. Daisychain 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.
