Analog Devices / Maxim Integrated MAX5214 & MAX5216 14/16-Bit Buffered Single DACs
Analog Devices Inc. MAX5214 and MAX5216 14/16-Bit Buffered Single Digital to Analog Converters (DACs) provide power consumption of less than 80µA IQ, allowing these DACs to prolong battery life in portable applications. ADI MAX5214 and MAX5216 DACs feature best-in-class accuracy, a small package size, and low current consumption, making these devices equally attractive in 2-wire sensors where low current levels must be measured, and power efficiency is important.
The MAX5214 and MAX5216 provide ±0.25 LSB and ±1 LSB of integral nonlinearity (INL), respectively, over their wide resolution spectrum. They are ideal for high-performance systems executing repetitive tasks in numerous counts that demand the same high precision and accuracy each time. These ADI DACs integrate an internal buffer that reduces the number of external components and total space required on the PCB. Buffer integration also simplifies design in.
The Maxim Integrated MAX5214 and MAX5216 DACs are available in an ultra-small 8-pin µMAX® package and are specified over the -40°C to +105°C extended industrial temperature range.
