1 / 37 page ADC12048 www.ti.com SNAS105B – APRIL 2000 – REVISED MARCH 2013 ADC12048 12-Bit Plus Sign 216 kHz 8-Channel Sampling Analog-to-Digital Converter Check for Samples: ADC12048 1 FEATURES DESCRIPTION Operating from a single 5V power supply, the 2 • 8-Channel Programmable Differential or ADC12048 is a 12 bit + sign, parallel I/O, self- Single-Ended Multiplexer calibrating, sampling analog-to-digital converter • Programmable Acquisition Times and User- (ADC) with an eight input fully differential analog Controllable Throughput Rates multiplexer. The maximum sampling rate is 216 kHz. On request, the ADC goes through a self-calibration • Programmable Data Bus Width (8/13 bits) process that adjusts linearity, zero and full-scale • Built-in Sample-and-Hold errors. • Programmable Auto-Calibration and Auto-Zero The ADC12048's 8-channel multiplexer is software cycles programmable to operate in a variety of combinations • Low Power Standby Mode of single-ended, differential, or pseudo-differential • No Missing Codes modes. The fully differential MUX and the 12-bit + sign ADC allows for the difference between two signals to be digitized. APPLICATIONS • Medical Instrumentation The ADC12048 can be configured to work with many popular microprocessors/microcontrollers and DSPs • Process Control Systems including Tl's HPC family, Intel386 and 8051, • Test Equipment TMS320C25, Motorola MC68HC11/16, Hitachi 64180 • Data Logging and Analog Devices ADSP21xx. • Inertial Guidance For complementary voltage references see the LM4040, LM4041 or LM9140. 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 Consumption – Normal Operation: 34 mW, Max – Stand-By Mode: 75 μw, Max 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. 2 All trademarks are the property of their respective owners.
