mcp42100 is a single-channel, 8-bit digital potentiometer features 100kΩ end-to-end resistance value with an SPI serial interface. The wiper position varies linearly and is controlled via the SPI interface. The MCP42100 has outstanding AC and DC characteristics, and consumes <1 µA during static operation.
Applications for the MCP42100 digital potentiometer include 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. The MCP42100 is available in 14-pin PDIP and SOIC packages.

Mcp42100 Features
Reliable Mcp42100 Distributor in China - Rantle East Electronic
mcp42100 features two resistor networks, potentiometer or Rheostat configuration options, 8-bit 255 resistors (256 Steps) and Zero-scale to full-scale wiper operation. Mcp42100 is a full-integrated synchronous boost converter with the load disconnect built-in. The device supports output voltage up to 16 V with a 3.8-A current limit. The input voltage ranges from 2.5-V to 5.5-V supporting applications powered by a single cell Lithium-ion battery or 5-V bus.
mcp42100 uses the peak current mode with the adaptive off-time control topology. The device works in PWM operation of 1.5 MHz at moderate-to-heavy loads. At the light load conditions, the device can be configured in either auto PFM or forced PWM operation by the MODE pin connection. Mcp42100 has a soft start to minimize the inrush current during start-up. Mcp42100 features of the load disconnect during shut down and provides a output short protection of hiccup mode. In addition, the device implements output overvoltage and thermal shutdown protection.
