See our web site for product availability. • Programmable Acquisition Time The ADC12030, and ADC12H030 families are 12-bit • Variable Digital Output Word Length and plus sign successive approximation Analog-to-Digital Format Converters with serial I/O and configurable input multiplexers. The ADC12034/ADC12H034 and • No Zero or Full Scale Adjustment Required ADC12038/ADC12H038 have 4 and 8 channel • Fully Tested and Ensured with a 4.096V multiplexers, respectively. The differential multiplexer Reference outputs and ADC inputs are available on the • 0V to 5V Analog Input Range with Single 5V MUXOUT1, MUXOUT2, A/DIN1 and A/DIN2 pins. The ADC12030/ADC12H030 has a two channel Power Supply multiplexer with the multiplexer outputs and ADC • No Missing Codes over Temperature inputs internally connected. The ADC12030 family is tested with a 5 MHz clock, while the ADC12H030 APPLICATIONS family is tested with an 8 MHz clock. On request, these ADCs go through a self calibration process that • Medical Instruments adjusts linearity, zero and full-scale errors to less • Process Control Systems than ±1 LSB each. • Test Equipment The analog inputs can be configured to operate in various combinations of single-ended, differential, or KEY SPECIFICATIONS pseudo-differential modes. A fully differential unipolar • Resolution 12-bit plus sign analog input range (0V to +5V) can be accommodated with a single +5V supply. In the • 12-bit plus sign conversion time differential modes, valid outputs are obtained even – ADC12H30 family 5.5 μs (max) when the negative inputs are greater than the positive – ADC12030 family 8.8 μs (max) because of the 12-bit plus sign output data format. • 12-bit plus sign throughput time The serial I/O is configured to comply with NSC – ADC12H30 family 8.6 μs (max) MICROWIRE. For voltage references see the LM4040, LM4050 or LM4041. – ADC12030 family 14 μs (max) • Integral Linearity Error ±1 LSB (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.
