DACs Extend Battery Life

For portable applications where power efficiency is ever a concern, the single-channel 14-bit MAX5214 and 16-bit MAX5216 d/a converters specify a power consumption of less than 80 μA. Their power consumption can be reduced further by writing the power-down sequence into the device registers. Additionally, on power-up, the devices reset their output to zero. Offering what is called best in class for accuracy and precision, the MAX5214 and MAX5216 provide ±0.25 LSB and ±1 LSB of integral nonlinearity, respectively. Other shared features include a buffer that reduces the number of external components necessary for system design and an operating temperature range from -40°C to +105°C. Available in eight-pin μMAX packages, pricing starts at $3.89 each/1,000. MAXIM INTEGRATED PRODUCTS, Sunnyvale, CA. (800) 998-8800.
