Features & Applications
The MCP41050 series of single-channel digital potentiometer features 8-bit resolution (256 wiper steps), and an industry-standard SPI™ serial interface.
The wiper position varies linearly and is controlled via the SPI interface. The MCP41050 has a resistance value of 50 kohm, outstanding AC and DC characteristics, and consumes <1 µA during static operation. The MCP41050 is available in 8-pin PDIP and SOIC packages.
Features:
- 256 taps for each potentiometer
- Potentiometer values for 10 kΩ, 50 kΩ and 100 kΩ
- Single and dual versions
- SPI™ serial interface (mode 0,0 and 1,1)
- ±1 LSB max INL & DNL
- Low power CMOS technology
- 1 µA maximum supply current in static operation
- Multiple devices can be daisy-chained together (MCP42XXX only)
- Shutdown feature open circuits of all resistors for maximum power savings
- Hardware shutdown pin available on MCP42XXX only
- Single supply operation (2. 7 V - 5. 5 V)
- Industrial temperature range: -40°C to +85°C
- Extended temperature range: -40°C to +125°C
Applications:
- Audio equipment (volume and tone controls)
- Servo-motor control
- Battery charging and control
- Communications (line impedance matching)
- Power supplies
- Instrumentation (gain, offset adjust)
- LCD contrast control and programmable filters
