Product specification

DAC08 Series

8-Bit high-speed multiplying D/A converter

August 31, 1994

723

LOGIC INPUT VOLTAGE (V)

10,000

NOTES:

B1 through B8 have identical transfer characteristics.

Bits are fully switched, with less than 1/2LSB error, at

less than

±100mV from actual threshold. These

switching points are guaranteed to lie between 0.8 and

2.0V over the operating temperature range

(VLC = 0.0V).
