X9015U

The X9015U is designed as one kind of single digitally controlled potentiometer with low noise,low power and volatile.It is a 32 tap potentiometer that is volatile.The device consists of a string of 31 resistors that can be programmed to connect the RW/VW wiper output with any of the nodes between the connecting resistors. The connection point of the wiper is determined by information communicated to the device on the 3-wire port. The 3-wire port changes the tap position by a falling edge on the increment pin. The direction the wiper moves is determined by the state of the up/down pin. The wiper position at power up is Tap #15.Also the X9015U can be used in a wide variety of applications that require a digitally controlled variable resistor to set analog values.

Features of the X9015U can be summarized as eight points:(1)3-wire up/down serial interface;(2)32 taps;(3)Vcc=2.7V-5V;(4)operating Icc=50A max.;(5)standby current=1A max.;(6)Rtotal=10k, 50k;(7)packages 8 Ld SOIC,8 Ld MSOP;(8)Pb-free plus anneal available (RoHS compliant).

The absolute maximum ratings of the X9015U are:(1)temperature under bias:-65°C to +135°C;(2)storage temperature:-65°C to +150°C;(3)lead temperature (soldering 10s):+300°C;(4)lead temperature (soldering 10s):+300°C;(5)temperature range commercial:0°C to +70°C;(6)temperature range industrial:-40°C to +85°C;(7)supply voltage (VCC):X9015U is 5V ±10%;(8)supply voltage (VCC):X9015-2.7 is 2.7V to 5.5V.
