    产品信息

    描述Operating from a single 5V power supply, the ADC12048 is a 12 bit + sign, parallel I/O, self-calibrating, sampling analog-to-digital converter (ADC) with an eight input fully differential analog multiplexer. The maximum sampling rate is 216 kHz. On request, the ADC goes through a self-calibration process that adjusts linearity, zero and full-scale errors.The ADC12048's 8-channel multiplexer is software programmable to operate in a variety of combinations of single-ended, differential, or pseudo-differential modes. The fully differential MUX and the 12-bit + sign ADC allows for the difference between two signals to be digitized. The ADC12048 can be configured to work with many popular microprocessors/microcontrollers and DSPs including Tl's HPC family, Intel386 and 8051, TMS320C25, Motorola MC68HC11/16, Hitachi 64180 and Analog Devices ADSP21xx.For complementary voltage references see the LM4040, LM4041 or LM9140.特性8-Channel Programmable Differential or Single-Ended Multiplexer Programmable Acquisition Times and User-Controllable Throughput Rates Programmable Data Bus Width (8/13 bits) Built-in Sample-and-Hold Programmable Auto-Calibration and Auto-Zero cycles Low Power Standby Mode No Missing Codes Key Specifications (fCLK = 12 MHz) Resolution: 12-Bits + Sign 13-Bit Conversion Time: 3.6 μs, Max 13-Bit Throughput Rate: 216 ksamples/s, Min Integral Linearity Error (ILE): ±1 LSB, Max Single Supply: +5 V ±10% VIN Range: GND to VA+ Power ConsumptionNormal Operation: 34 mW, MaxStand-By Mode: 75 μw, Max All trademarks are the property of their respective owners.
