Fonctionnalités et applications

The MCP42010 series of digital potentiometer features two independent channels, 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 MCP42010 has a resistance value of 10 kohm, outstanding AC and DC characteristics, and consumes <1 µA during static operation. The MCP42010 is available in 14-pin PDIP, SOIC and TSSOP 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 MCP42XX 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
