Description
The MCP41XX and MCP42XX devices offer a wide range of product offerings that use an SPI interface. This family of devices supports 7-bit and 8-bit resistor networks, as well as potentiometer and rheostat pinouts.
Features
• One/two resistor network
options • Potentiometer or rheostat configuration options
• Resistor network resolution
– 7-bit: 128 resistors (129 steps)
– 8-bit: 256 resistors (257 steps)
• Wiper operation from zero scale to full scale Scale
• Low Wiper Resistance: 75O (typical)
• Low Tempco:
– Absolute (Rheostat): 50 ppm typical (0°C to 70°C)
– Ratiometric (potentiometer): 15ppm typical
• Serial SPI interface (10MHz, modes 0.0 & 1.1)
– Fast read/write of wiper registers
– SDI/SDO multiplexing (MCP41X1 only)
• Resistive network terminal isolation function via:
– Shutdown Pin (SHDN)
– Terminal Control (TCON) register
• Brown-out reset protection (1.5V typical)
• Serial interface idle current (2.5uA typical)
• High voltage tolerant digital inputs: Up to 12, 5V
• Supports split rail applications
– Internal weak pull-up on all digital inputs
– Wide operating voltage:
– 2.7V to 5.5V – Device characteristics Specified
– 1.8V to 5.5V – Device operation
• Wide bandwidth operation (-3 dB):
– 2 MHz (typical) for 5.0 kO device
• Extended temperature range (-40°C to +125°C)
