1 / 52 page  ADC12130, ADC12132, ADC12138 www.ti.com SNAS098G – MARCH 2000 – REVISED MARCH 2013 ADC12130/ADC12132/ADC12138 Self-Calibrating 12-Bit Plus Sign Serial I/O A/D Converters with MUX and Sample/Hold Check for Samples: ADC12130, ADC12132, ADC12138 1 FEATURES DESCRIPTION NOTE: Some device/package combinations are 2 • Serial I/O (MICROWIRE, SPI and QSPI obsolete and are described and shown here for Compatible) reference only. See our web site for product • Power Down Mode availability. • Programmable Acquisition Time The ADC12130, ADC12132 and ADC12138 are 12- • Variable Digital Output Word Length and bit plus sign successive approximation Analog-to- Format Digital converters with serial I/O and configurable input multiplexer. The ADC12132 and ADC12138 • No Zero or Full Scale Adjustment Required have a 2 and an 8 channel multiplexer, respectively. • 0V to 5V Analog Input Range with Single 5V The differential multiplexer outputs and ADC inputs Power Supply are available on the MUXOUT1, MUXOUT2, A/DIN1 and A/DIN2 pins. The ADC12130 has a two channel APPLICATIONS multiplexer with the multiplexer outputs and ADC inputs internally connected. The ADC12130 family is • Pen-Based Computers tested and specified with a 5 MHz clock. On request, • Digitizers these ADCs go through a self calibration process that • Global Positioning Systems adjusts linearity, zero and full-scale errors to typically less than ±1 LSB each. KEY SPECIFICATIONS The analog inputs can be configured to operate in • Resolution 12-bit plus sign various combinations of single-ended, differential, or pseudo-differential modes. A fully differential unipolar • 12-Bit plus sign conversion time 8.8 μs (max) analog input range (0V to +5V) can be • 12-Bit plus sign throughput time 14 μs (max) accommodated with a single +5V supply. In the • Integral Linearity Error ±2 LSB (max) differential modes, valid outputs are obtained even when the negative inputs are greater than the positive • Single Supply 3.3V or 5V ±10% because of the 12-bit plus sign output data format. • Power Consumption The serial I/O is configured to comply with NSC – +3.3V 15 mW (max) MICROWIRE. For voltage references, see the – +3.3V power down 40 μW (typ) LM4040, LM4050 or LM4041. – +5V 33 mW (max) – +5V power down 100 μW (typ) 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.
