Maxim Integrated MAX526DCNG

Description
The MAX526/MAX527 are quad 12-bit voltage-output digital-to-analog converters (DACs). They feature precision output buffer amplifiers for voltage outputs. The MAX527 operates with ±15V power supplies, while the MAX526 uses ±5V to ±12V to ±15V supplies. Offset gain and linearity are factory calibrated to provide the MAX526's 1LSB total unadjusted error (TUE). These devices have double-buffered interface logic with a 12-bit input and a 12-bit DAC register. Data in the DAC register sets the DAC output voltage. The MAX526/MAX527 have an 8-bit-wide data bus. Data is loaded into the input register using two write operations with an 8-bit LSB write load and a 4-bit MSB write load. An asynchronous load DAC (LDAC) input transfers data from the input register to the DAC register. All logic inputs are TTL and CMOS compatible.
