FEATURES  
DESCRIPTION  
NOTE: These products are now obsolete.  
23  
0V to 3.3V Analog Input Range with Single  
3.3V Supply  
The ADC12L030 family is 12-bit plus sign successive  
approximation 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, respectively. 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 that adjusts linearity, zero and full-  
scale errors to less than ±½ LSB each.

APPLICATIONS  
Portable Medical Instruments  
Portable Computing  
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.  
Portable Test Equipment  
KEY SPECIFICATIONS  
Resolution: 12-bit Plus Sign  
12-bit Plus Sign Conversion Time: 8.8 µs (min)  
12-bit Plus Sign Sampling Rate: 73 kHz (max)  
Integral Linearity Error: ±1 LSB (max)  
Single Supply: 3.3V ±10%  
The serial I/O is configured to comply with TI's  
MICROWIRE and Motorola's SPI standards. For  
voltage references, see the LM4040, LM4050 or  
LM4041 data sheets.  
Power Consumption, Active: 15 mW (max)  
Power Consumption, Power Down: 40 µW (typ)  
The ADC12L032 and the ADC12L034 are not  
recommended for new designs and are presented for  
reference only.
