Description

DESCRIPTION
The DAC7512 is a low-power, single, 12-bit buffered voltage output Digital-to-Analog Converter (DAC). Its on-chip precision output amplifier allows rail-to-rail output swing to be achieved. The DAC7512 uses a versatile three-wire serial interface that operates at clock rates up to 30MHz and is compatible with standard SPI™, QSPI™, Microwire™, and DSP interfaces.
The reference for the DAC7512 is derived from the power supply, resulting in the widest dynamic output range possible. The DAC7512 incorporates a power-on reset circuit that ensures that the DAC output powers up at 0V and remains there until a valid write takes place in the device. The DAC7512 contains a power-down feature, accessed over the serial interface, that can reduce the current consumption of the device to 50nA at 5V

FEATURES
● microPOWER OPERATION: 135µA at 5V
● POWER-DOWN: 200nA at 5V, 50nA at 3V
● POWER SUPPLY: +2.7V to +5.5V
● TESTED MONOTONIC BY DESIGN
● POWER-ON RESET TO 0V
● THREE POWER-DOWN FUNCTIONS
● LOW POWER SERIAL INTERFACE WITH SCHMITT-TRIGGERED INPUTS
● ON-CHIP OUTPUT BUFFER AMPLIFIER, RAIL-TO-RAIL OPERATION
● SYNC INTERRUPT FACILITY
● SOT23-6 AND MSOP-8 PACKAGES

APPLICATIONS
● PORTABLE BATTERY-POWERED INSTRUMENTS
● DIGITAL GAIN AND OFFSET ADJUSTMENT
● PROGRAMMABLE VOLTAGE AND CURRENT SOURCES
