Overview
DAC8532 SBAS246A – DECEMBER 2001 – MAY 2003 Dual Channel, Low Power, 16-Bit, Serial Input DIGITAL-TO-ANALOG CONVERTER FEATURES q microPOWER OPERATION: 500µA at 5V q POWER-ON RESET TO ZERO-SCALE q POWER SUPPLY: +2.
7V to +5.
5V q 16-BIT MONOTONIC OVER TEMPERATURE q SETTLING TIME: 10µs to ±0.
003% FSR q ULTRA-LOW AC CROSSTALK: –100dB typ q LOW-POWER SERIAL INTERFACE WITH SCHMITT-TRIGGERED INPUTS q ON-CHIP OUTPUT BUFFER AMPLIFIER WITH RAIL-TO-RAIL OPERATION q DOUBLE BUFFERED INPUT ARCHITECTURE q SIMULTANEOUS OR SEQUENTIAL OUTPUT UPDATE AND POWERDOWN q TINY MSOP-8 PACKAGE DESCRIPTION The DAC8532 is a dual channel, 16-bit Digital-to-Analog Converter (DAC) offering low power operation and a flexible serial host interface.
Each on-chip precision output amplifier allows rail-to-rail output swing to be achieved over the supply range of 2.
7V to 5.
5V.
The device supports a standard 3-wire serial interface capable of operating with input data clock frequencies up to 30MHz for VDD = 5V.
The DAC8532 requires an external reference voltage to set the output range of each DAC channel.
Also incorporated into the device is a power-on reset circuit which ensures that the DAC outputs power up at zero-scale and remain there until a valid write takes place.
The DAC8532 provides a flexible power-down feature, accessed over the serial interface, that reduces the current consumption of the device to 200nA at 5V.
The low-power consumption of this device in normal operation makes it ideally suited to portable battery-operated equipment and other low-power applications.
The power consumption is 2.
5mW at 5V, reducing to 1µW in powerdown mode.
The DAC8532 is available in a MSOP-8 package with a specified operating temperature range of –40°C to +105°C.
