The MCP4331T-104E/ST is a 7/8-bit quad SPI digital potentiometer featuring a volatile memory configuration. It offers a choice between potentiometer and rheostat configurations, with resistor network resolutions of 128 taps for 7-bit and 256 taps for 8-bit. The device is available in resistance options of 5 kOc, 10 kOc, 50 kOc, and 100 kOc, with a typical low wiper resistance of 75 Oc. The MCP4331T-104E/ST operates over a wide voltage range of 1.8V to 5.5V, with specified characteristics from 2.7V to 5.5V. It supports high-speed SPI communication at 10 MHz and includes features such as a terminal disconnect capability, brown-out reset protection, and low quiescent current of 2.5 ¬µA. The device is rated for an extended temperature range of -40¬8C to +125¬8C, making it suitable for various applications. Engineers considering this product should note its compatibility with split rail applications and high-voltage tolerant digital inputs up to 12.5V. The MCP4331T-104E/ST is packaged in a TSSOP format, facilitating integration into compact designs.
