The DAC8412 / DAC8413 are quad, 12-bit voltage output DACs with readback capability. Built using a complementary BiCMOS process, these monolithic DACs offer the user very high package density.Output voltage swing is set by the two reference inputs VREFH and VREFL. By setting the VREFL input to 0 V and VREFH to a positive voltage, the DAC provides a unipolar positive output range. A similar configuration with VREFH at 0 V and VREFL at a negative voltage provides a unipolar negative output range. Bipolar outputs are configured by connecting both VREFH and VREFL to nonzero voltages. This method of setting output voltage range has advantages over other bipolar offsetting methods because it is not dependent on internal and external resistors with different temperature coefficients.Digital controls allow the user to load or read back data from any DAC, load any DAC, and transfer data to all DACs at one time.An active low RESET loads all DAC output registers to midscale for the DAC8412 and zero scale for the DAC8413.The DAC8412 / DAC8413 are available in 28-lead plastic DIP, 28-lead ceramic DIP, 28-lead PLCC, and 28-lead LCC packages.They can be operated from a wide variety of supply and reference voltages with supplies ranging from single +5 V to ±15 V, and references from +2.5 V to ±10 V. Power dissipation is less than 330 mW with ±15 V supplies and only 60 mW with a +5 V supply.For MIL-STD-883 applications, contact your local Analog Devices, Inc. sales office for the DAC8412/DAC8413/883 data sheet, which specifies operation over the −55°C to +125°C temperature range.

The AD7874 is a four-channel simultaneous sampling, 12-bit data acquisition system. The part contains a high speed 12-bit ADC, on chip reference, on-chip clock and four track/hold amplifiers. This latter feature allows the four input channels to be sampled simultaneously, thus preserving the relative phase information of the four input channels, which is not possible if all four channels share a single track/hold amplifier. This makes the AD7874 ideal for applications such as phased-array sonar and ac motor controllers where the relative phase information is important.The aperture delay of the four track/hold amplifiers is small and specified with minimum and maximum limits. This allows several AD7874s to sample multiple input channels simultaneously without incurring phase errors between signals connected to several devices. A reference output/reference input facility also allows several AD7874s to be driven from the same reference source.In addition to the traditional dc accuracy specifications such as linearity, full-scale and offset errors, the AD7874 is also fully specified for dynamic performance parameters including distortion and signal-to-noise ratio.The AD7874 is fabricated in Analog Devices' Linear Compatible CMOWS (LC2MOS) process, a mixed technology process that combines precision bipolar circuits with low-power CMOS logic. The part is available in a 28-pin, 0.6' wide, plastic or hermetic dual-in-line package (DIP), in a 28-terminal leadless ceramic chip carrier (LCCC) and in a 28-pin SOIC.PRODUCT HIGHLIGHTS Simultaneous Sampling of Four Input Channels. Four input channels, each with its own track/hold amplifier, allow simultaneous sampling of input signals. Track/hold acquisition time is 2 µs, and the conversion time per channel is 8 µs, allowing 29 kHz sample rate for all four channels. Tight Aperture Delay Matching. The aperture delay for each channel is small and the aperture delay matching between the four channels is less than 4 ns. Additionally, the aperture delay specification has upper and lower limits allowing multiple AD7874s to sample more than four channels. Fast Microprocessor Interface. The high speed digital interface of the AD7874 allows direct connection to all modern 16-bit microprocessors and digital signal processors.APPLICATIONS Sonar Motor Controllers Adaptive Filters Digital Signal Processing
