Digital Pots Address Power Sensitive Designs

Operating from a low, 1.7V supply, the MAX5391 through MAX5393 debut as the industry's lowest voltage digital potentiometers. The dual, 256-tap, volatile digital potentiometers operate from a single 1.7V to 5.5V power supply, making them suitable for replacing mechanical potentiometers and DACs in power-sensitive applications. The MAX5391 and MAX5393 include two digital potentiometers in a voltage-divider configuration. The devices have a 5 ppm/°C ratiometric temperature coefficient and come in three different end-to-end resistance values of 10 k?, 50 k?, and 100 k?. SPI-compatible and I²C control interfaces are also available. Offered in TQFN or TSSOPs, prices start at $1.32 each/1,000. MAXIM INTEGRATED PRODUCTS, Sunnyvale, CA. (800) 998-8800.
