Aquisição de Dados - Conversores Digital para Analógico (DAC)

The AD7226KNZ is an 8-bit voltage-output Digital-to-analog Converter with output buffer amplifiers and interface logic on a single monolithic chip. No external trims are required to achieve full specified performance for the part. Data is transferred into one of these data latches through a common 8-bit TTL/CMOS (5V) compatible input port. Control inputs A0 and A1 determine which DAC is loaded when WR goes low. The control logic is speed-compatible with most 8-bit microprocessors. The amplifier offset is laser-trimmed during manufacture, thereby eliminating any requirement for offset nulling. Specified performance is guaranteed for input reference voltages from 2 to 12.5V with dual supplies. It is fabricated in an all ion-implanted high speed Linear Compatible CMOS process, which has been specifically developed to allow high speed digital logic circuits and precision analog circuits to be integrated on the same chip.

The AD7568 contains eight 12-bit DACs in one monolithic device. The DACs are standard current output with seperate VREF, IOUT1, IOUT2 and RFB terminals. The AD7568 is a serial input device. Data is loaded using FSIN, CLKIN and SDIN. One address pin, A0, sets up a device address, and this feature may be used to simplify device loading in a multi-DAC environment. All DACs can be simultaneously updated using the asynchronous LDAC input, and they can be cleared by asserting the asynchronous CLR input. The AD7568 is housed in a space-saving 44-pin plastic quad flatback and 44-lead PLCC. APPLICATIONS Process Control Automatic Test Equipment General Purpose Instrumentation

Quad 8-Bit DACs with Rail-to-Rail Voltage Outputs

The AD7237A/AD7247A is an enhanced version of the industry standard AD7237/AD7247. Improvements include operation from 12 V to 15 V supplies, faster interface times and better reference variations with VDD . Additional features include faster settling times. The AD7237A/AD7247A is a complete, dual, 12-bit, voltage output digital-to-analog converter with output amplifiers and Zener voltage reference on a monolithic CMOS chip. No external user trims are required to achieve full specified performance. Both parts are microprocessor compatible, with high speed data latches and interface logic. The AD7247A accepts 12-bit parallel data which is loaded into the respective DAC latch using the WR input and a separate Chip Select input for each DAC. The AD7237A has a double buffered interface structure and an 8-bit wide data bus with data loaded to the respective input latch in two write operations. An asynchronous LDAC signal on the AD7237A updates the DAC latches and analog outputs. A REF OUT/REF IN function is provided which allows either the on-chip 5 V reference or an external reference to be used as a reference voltage for the part. For single supply operation, two output ranges of 0 V to +5 V and 0 V to +10 V are available, while these two ranges plus an additional ±5 V range are available with dual supplies. The output amplifiers are capable of developing +10 V across a 2 k(ohm) load to GND. The AD7237A/AD7247A is fabricated in Linear Compatible CMOS (LC2 MOS), an advanced, mixed technology process that combines precision bipolar circuits with low power CMOS logic. Both parts are available in a 24-pin, 0.3" wide plastic and hermetic dual-in-line package (DIP) and are also packaged in a 24-lead small outline (SOIC) package.
