LOW-COST, LOW-POWER DAC FAMILY IS I2C COMPATIBLE
SUNNYVALE, CA—August 21, 2000— Maxim Integrated Products announces the MAX5360/MAX5361/MAX5362 and the MAX5380/MAX5381/MAX5382, a family of ultra-low-power, 6-bit and 8-bit voltage-output, digital-to-analog converters (DACs) in miniature 5-pin SOT23 package. These DACs with a simple 2-wire interface operate from a single +2.7V to +5.5V supply, offer rail-to-rail precision internal amplifiers, and consume ultra-low supply current (130µA typically). A 1µA shutdown current further reduces power. The devices’ small size, combined with their low power consumption, optimize them for portable and battery-powered equipment. The fast-mode, I2C™-compatible serial interface allows communication with multiple devices with reduced interconnect complexity.
Included on-chip are a current-steering DAC, a class AB buffer amplifier capable of driving resistive and capacitive loads, an internal bandgap reference (MAX5360/MAX5361 and MAX5380/MAX5381), and a proprietary deglitch circuit that eliminates power-up glitches at the DAC output. The power-on reset circuit ensures the devices power up to 0V and remain there until a valid write takes place. With their reference derived from the power supply inputs, the MAX5362 and MAX5382 give the widest dynamic output range (0 to supply). The MAX5360/MAX5361 and MAX5380/MAX5381 provide supply-independent output levels and high PSRR specifications without an external reference. Maximum linearity performance is specified at ±1LSB for all the devices.
Available in a 5-pin SOT23 package, the devices’ simple 2-wire serial interface operates at clock rates up to 400kHz. Prices start at $0.95 for MAX5380/MAX5381/5382 and $0.65 for MAX5360/MAX5361/MAX5362 (1000-up, FOB USA).
