DAC7512

SBAS156B – JULY 2002

Low-Power, Rail-to-Rail Output, 12-Bit Serial Input

DIGITAL-TO-ANALOG CONVERTER

FEATURES

ꢀꢀmicroPOWER OPERATION: 135µA at 5V

ꢀ POWER-DOWN: 200nA at 5V, 50nA at 3V

ꢀ POWER SUPPLY: +2.7V to +5.5V

DESCRIPTION

The DAC7512 is a low-power, single, 12-bit buffered voltage

output Digital-to-Analog Converter (DAC). Its on-chip preci-

sion 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.

TESTED MONOTONIC BY DESIGN

ꢀ POWER-ON RESET TO 0V

ꢀ THREE POWER-DOWN FUNCTIONS

ꢀ LOW POWER SERIAL INTERFACE WITH

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.

APPLICATIONS

The low power consumption of this part in normal operation

makes it ideally suited to portable battery-operated equip-

ment. The power consumption is 0.7mW at 5V reducing to

1µW in power-down mode.
