DESCRIPTION

This Digital-to-Analogconverteris a monolithicvoltage

output converter which can accept TTL-level

digital input voltages.

The STV8438CV contains three 8-bit D/A converters

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 particularlyrecommended for use in

video processing applications with the capability of

70Msps data conversion rate with excellent

linearity.
