DESCRIPTION

This Digital-to-Analogconverteris a monolithic volt-

age output converter which can accept TTL-level

digital input voltages.

The STV8438CV contains three 8-bit D/A con-

verters with a high performance on-chip voltage

reference.

Internal analog multiplexing between the signals

from the internal D/A converter and from auxiliary

analog R, G, B signals is provided. Either binary or

2’s complement inputs are available for two of the

three channels.

This device is particularly recommended for use in

video processing applications with the capability of

70Msps

data

conversion

rate with excellent

linearity.
