x9438 Intersil Corporation, x9438 Datasheet - Page 10

• Manufacturer Part Number: x9438
• Description: Dual Digitally Controlled Potentiometer Xdcp With Operational Amplifier
• Manufacturer: Intersil Corporation

AMPLIFIER ELECTRICAL CHARACTERISTICS
(Over the recommended operating conditions unless otherwise specified.)
V+ and V- (r5V to r3V) are the amplifier power supplies. The amplifiers are specified with dual power supplies. V
is the logic supply. All ratings are over the temperature range for the Industrial (-40 to + 85°C) and Commercial (0 to 70° C)
versions of the part unless specified differently.
