32-Channel 14-Bit DAC with a High-Speed 3-Wire Serial Interface AD5532HS FEATURES GENERAL DESCRIPTION 2 High Integration: 32-Channel DAC in 12 12 mm LFBGA The AD5532HS is a 32-channel voltage-output 14-bit DAC Guaranteed Monotonic with a high-speed serial interface. The selected DAC register is DSP-/Microcontroller-Compatible Serial Interface written to via the 3-wire interface. The serial interface operates Channel Update Rate 1.1 MHz at clock rates up to 30 MHz and is compatible with DSP and Output Impedance 0.5 microcontroller interface standards. The output voltage range is Selectable Output Voltage 0 V to 5 V or 2.5 V to +2.5 V 0 V to 5 V or 2.5 V to +2.5 V and is determined by the offset Asynchronous RESET Facility voltage at the OFFS IN pin. It is restricted to a range from Temperature Range 40 C to +85 C V + 2 V to V 2 V because of the headroom of the out- SS DD put amplifier. APPLICATIONS The device is operated with AV = 5 V 5%, DV = 2.7 V CC CC Optical Networks to 5.25 V, V = 4.75 V to 12 V and V = +4.75 V to +12 V SS DD Level Setting and requires a stable 2.5 V reference on REF IN. Instrumentation Automatic Test Equipment PRODUCT HIGHLIGHTS Industrial Control Systems 1. 32 14-bit DACs in one package, guaranteed monotonic. Data Acquisition Low Cost I/O 2. The AD5532HS is available in a 74-ball LFBGA package with a body size of 12 mm by 12 mm.
