The AD660 DACPORT® is a complete 16-bit monolithic digital-to-analog converter with an on-board voltage reference, double-buffered latches, and an output amplifier. It is manufactured on the Analog Devices, Inc., BiMOS II process. This process allows the fabrication of low power CMOS logic functions on the same chip as high precision bipolar linear circuitry.
The AD660 architecture ensures 15-bit monotonicity over time and temperature. Integral and differential nonlinearity is maintained at ±0.003% maximum. The on-chip output amplifier provides a voltage output settling time of 10 μs to within ½ LSB for a full-scale step.
The AD660 has an extremely flexible digital interface. Data can be loaded into the AD660 in serial mode or as two 8-bit bytes. This is made possible by two digital input pins that have dual functions. The serial mode input format is pin selectable to be MSB or LSB first. The serial output pin allows the user to daisy-chain several AD660 devices by shifting the data through the input latch into the next DAC, thus minimizing the number of control lines required to SIN, CS and LDAC. The byte mode input format is also flexible in that the high byte or low byte data can be loaded first. The double buffered latch structure eliminates data skew errors and provides for simultaneous updating of DACs in a multiDAC system.
The AD660 is available in five grades. AN and BN versions are specified from −40°C to +85°C and are packaged in a 24-lead300 mil plastic DIP. AR and BR versions are also specified from −40°C to +85°C and are packaged in a 24-lead SOIC. The SQ version is packaged in a 24-lead 300 mil CERDIP package and is also available compliant to MIL-STD-883. Refer to theAD660SQ/883B military data sheet for specifications and test conditions.
Product Highlights

    The AD660 is a complete 16-bit DAC, with a voltage reference, double-buffered latches, and an output amplifier on a single chip.
    
    The internal buried Zener reference is laser trimmed to 10.000 V with a ±0.1% maximum error and a temperature drift performance of ±15 ppm/°C. The reference is available for external applications.
    
    The output range of the AD660 is pin programmable and can be set to provide a unipolar output range of 0 V to 10 Vor a bipolar output range of −10 V to +10 V. No external components are required.
    
    The AD660 is both dc and ac specified. DC specifications include ±1 LSB INL and ±1 LSB DNL errors. AC specifications include 0.009% THD + N and 83 dB SNR.
    
    The double-buffered latches on the AD660 eliminate data skew errors and allow simultaneous updating of DACs inmultiDAC applications.
    
    The clear function can asynchronously set the output to 0 V regardless of whether the DAC is in unipolar or bipolar mode.
    
    The output amplifier settles within 10 μs to ±½ LSB for a full-scale step and within 2.5 μs for a 1 LSB step over temperature. The output glitch is typically 15 nV-s when a full-scale step is loaded.
    




Data Sheet, Rev. B, 6/08

The AD7233 is a complete 12-bit, voltage-output, digital-to-analog converter with output amplifier and Zener voltage reference all in an 8-pin package.  No external trims are required to achieve full specified performance.  The data format is 2s complement, and the output range is -5V to +5V.
The AD7233 features a fast, versatile serial interface which allows easy connection to both microcomputers and 16-bit digital signal processors with serial ports.  When the SYNC input is taken low, data on the SDIN pin is clocked into the input shift register on each falling edge of SCLK.  ON completion of the 16-bit data transfer, bringing LDAC low updates the DAC latch with the lower 12 bits of data and updates the output.  Alternatively, LDAC can be tied permanently low, and in this case the DAC register is automatically updated with the contents of the shift register when all sixteen data bits have been clocked in.  The serial data may be applied at rates up to 5 MHz allowing a DAC update rate of 300 kHz.
For applications which require greater flexibility and unipolar output ranges with single supply operation, please refer to the AD7243 data sheet.
The AD7233 is fabricated on Linear Compatible CMOS (LC2MOS), an advanced, mixed-technology process.  It is packaged in an 8-pin DIP package.

The AD9914 is a direct digital synthesizer (DDS) featuring a 12-bit DAC targeted at operating up to 3.5 GSPS. The AD9914 uses advanced DDS technology, coupled with an internal high speed, high performance DAC to form a digitally programmable, complete high frequency synthesizer capable of generating a frequency-agile analog output sinusoidal waveform at up to 1.4 GHz. The AD9914 is designed to provide fast frequency hopping and fine tuning resolution (32 bit in standard mode, 64 bit capable using programmable modulus mode). The AD9914 also offers fast phase and amplitude hopping capability. The frequency tuning and control words are loaded into the AD9914 via a serial or parallel input/output port. The AD9914 also supports a user defined linear sweep mode of operation for generating highly linear swept waveforms of frequency, phase or amplitude. A high speed parallel data input port is included enabling high data rates for polar modulation schemes and fast reprogramming of the phase, frequency and amplitude tuning words.
The AD9914 is specified to operate over the extended industrial temperature range (see Absolute Max Ratings table found in the data sheet).
