AD5532HS

a 32-Channel 14-Bit DAC with High-Speed 3-Wire Serial Interface AD5532HS* GENERAL DESCRIPTION FEATURES High Integration: 32-Channel DAC in 12 ؋ 12 mm2 LFBGA Guaranteed Monotonic DSP-/Microcontroller-Compatible Serial Interface Channel Update Rate 1.1 MHz Output Impedance 0.5 ⍀ Selectable Output Voltage 0 V to 5 V or –2.5 V to +2.5 V Asynchronous RESET Facility Temperature Range –40؇C to +85 ؇C APPLICATIONS Optical Networks Level Setting Instrumentation Automatic Test Equipment Industrial Control Systems Data Acquisition Low Cost I/O The AD5532HS is a 32-channel voltage-output 14-bit DAC with a high-speed serial interface. The selected DAC register is written to via the 3-wire interface. The serial interface operates at clock rates up to 30 MHz and is compatible with DSP and microcontroller interface standards. The output voltage range is 0 V to 5 V or –2.5 V to +2.5 V and is determined by the offset voltage at the OFFS_IN pin. It is restricted to a range from VSS + 2 V to VDD – 2 V because of the headroom of the output amplifier. The device is operated with AVCC = 5 V ± 5%, DVCC = 2.7 V to 5.25 V, VSS = –4.75 V to –12 V and VDD = +4.75 V to +12 V and requires a stable 2.5 V reference on REF_IN. PRODUCT HIGHLIGHTS 1. 32 14-bit DACs in one package, guaranteed monotonic. 2. The AD5532HS is available in a 74-ball LFBGA package with a body size of 12 mm by 12 mm.
