The SP98608 is an ECL 10K compatible 8-bit latched
DAC. The 2.2nsec settling time allows a 450 megasample
per second conversion rate. An inherently low glitch design
is used and the complementary current outputs are suitable
for direct transmission line drive. The SP98608 design
includes a high performance band-gap voltage reference
and reference amplier.
Both current and voltage multiplying modes are availa-
ble. The input latch can be switched into transparent mode
for applications that require low through delay.
