LOW-VOLTAGE, 8-BIT QUAD DAC HAS ON-CHIP NONVOLATILE MEMORY
SUNNYVALE, CA-February 5, 2001-Maxim Integrated Products introduces the MAX5105 and MAX5106. These 8-bit, quad, nonvolatile DACs offer a low-power solution for applications such as digital gain and offset adjustments. The nonvolatile memory allows digital states to be stored for automatic return to previous states at the DAC output voltages. The MAX5106 in 16-pin QSOP is 78% smaller than comparable devices offered in larger SOIC packages.
These devices operate with +2.7V to +5.5V single supplies. The reference inputs can accept voltages from ground to VDD. These devices also feature independent high and low reference inputs, and output buffer amplifiers that swing rail-to-rail. The MAX5105/MAX5106 use 1mA of supply current and incorporate a 1µA shutdown mode to further reduce power consumption in standby mode. The MAX5105 offers the user the ability to simultaneously shut down all four DACs or to disable each DAC individually.
The DAC output settles accurately in 6µs to a full-scale code change. The MAX5105/MAX5106 are accurate to ±1LSB INL and DNL. Prices for the MAX5105 in 20-pin QSOP and the MAX5106 in 16-pin QSOP start at $2.80 (1000-up, FOB USA).
