Quick Detail:
Self-Calibrating 12-Bit Plus Sign Serial I/O A/D Converters with MUX and Sample/Hold
Description:
The ADC12130, ADC12132 and ADC12138 are 12-bit plus sign successive approximation A/D converters with serial I/O and configurable input multiplexer. The ADC12132 and ADC12138 have a 2 and an 8 channel multiplexer, respectively. The differential multiplexer outputs and A/D inputs are available on the MUXOUT1, MUXOUT2, A/DIN1 and A/DIN2 pins. The ADC12130 has a two channel multiplexer with the multiplexer outputs and A/D inputs internally connected. The ADC12130 family is tested with a 5 MHz clock. On request, these A/Ds go through a self calibration process that adjusts linearity, zero and full-scale errors to typically less than ±1 LSB each.
The analog inputs can be configured to operate in various combinations of single-ended, differential, or pseudo-differential modes. A fully differential unipolar analog input range (0V to +5V) can be accommodated with a single +5V supply. In the differential modes, valid outputs are obtained even when the negative inputs are greater than the positive because of the 12-bit plus sign output data format.
The serial I/O is configured to comply with the NSC MICROWIRE™. For voltage references, see the LM4040 or LM4041.
Applications:
- Serial I/O (MICROWIRE, SPI and QSPI Compatible)
- 2 or 8 channel differential or single-ended multiplexer
- Analog input sample/hold function
- Power down mode
- Programmable acquisition time
- Variable digital output word length and format
- No zero or full scale adjustment required
- 0V to 5V analog input range with single 5V power supply
