ADC12L030/ADC12L032/ADC12L034/ADC12L038  
3.3V Self-Calibrating 12-Bit Plus Sign Serial I/O A/D  
Converters with MUX and Sample/Hold  
General Description  
Features  
n 0V to 3.3V analog input range with single 3.3V supply  
n Serial I/O ( MICROWIRE and SPI Compatible)  
n 2 or 8 channel differential or single-ended multiplexer  
n Power down mode  
NOTE: These products are now obsolete.  
The ADC12L030 family is 12-bit plus sign successive ap-  
proximation A/D converters with serial I/O and configurable  
input multiplexers. These devices are fully tested with a  
single 3.3V power supply. The ADC12L032, ADC12L034 and  
ADC12L038 have 2, 4 and 8 channel multiplexers, respec-  
tively. Differential multiplexer outputs and A/D inputs are  
available at the MUXOUT1, MUXOUT2, A/DIN1 and A/DIN2  
pins. The ADC12L030 has a two channel multiplexer with the  
multiplexer outputs and A/D inputs internally connected. On  
request, these A/Ds go through a self calibration process  
n Programmable acquisition time  
n Variable digital output word length and format  
n No zero or full scale adjustment required

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 +3.3V) can be accommodated with a single  
+3.3V 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 two’s compliment  
output data format.  
15 mW (max)  
40 µW (typ)  
Applications  
n Portable Medical instruments  
n Portable computing  
The serial I/O is configured to comply with NSC’s  
n Portable Test equipment  
MICROWIRE and Motorola’s SPI standards. For voltage  
references, see the LM4040, LM4050 or LM4041 data  
sheets.  
The ADC12L032 and the ADC12L034 are not recommended  
for new designs and are presented for reference only.
