AD7237JR Descrição geral
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.
Características
- Resolution: 12 bits, which means it can convert digital input codes into analog output voltages with 4096 possible levels.
- Output Voltage Range: Typically ±10V, which means it can generate analog output voltages in the range of -10V to +10V.
- Fast Conversion Rate: AD7237JR is capable of converting digital input codes into analog output voltages at a high conversion rate of up to 100 kSPS (thousand samples per second).
- Low Glitch Impulse: It has low glitch impulse, which ensures that the output voltage settles quickly and accurately after a change in the digital input code.
- Flexible Interface: It has various digital interface options including parallel, serial, and multiplexed serial interface modes, making it adaptable to different system requirements.
Aplicativo
- Process Control: It can be used in industrial control systems for generating precise analog control signals for process control applications.
- Instrumentation: It can be used in test and measurement instruments for generating accurate analog signals for calibration or testing purposes.
- Audio Systems: It can be used in audio systems for digital audio processing and sound synthesis applications.
- Communication Systems: It can be used in communication systems for generating analog signals for modulation or demodulation purposes.
