FEATURES  
DESCRIPTION  
NOTE: Some device/package combinations are  
obsolete and are described and shown here for  
reference only. See our web site for product  
availability.  
2
Serial I/O (MICROWIRE, SPI and QSPI  
Compatible)  
Power Down Mode  
Programmable Acquisition Time  
The ADC12130, ADC12132 and ADC12138 are 12-  
bit plus sign successive approximation Analog-to-  
Digital 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 ADC 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 ADC  
inputs internally connected. The ADC12130 family is  
tested and specified with a 5 MHz clock. On request,  
these ADCs go through a self calibration process that  
adjusts linearity, zero and full-scale errors to typically  
less than ±1 LSB each.  
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  
APPLICATIONS  
Pen-Based Computers  
Digitizers  
Global Positioning Systems  
KEY SPECIFICATIONS  
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.  
Resolution 12-bit plus sign  
12-Bit plus sign conversion time 8.8 μs (max)  
12-Bit plus sign throughput time 14 μs (max)  
Integral Linearity Error ±2 LSB (max)  
Single Supply 3.3V or 5V ±10%  
Power Consumption  
The serial I/O is configured to comply with NSC  
MICROWIRE. For voltage references, see the  
LM4040, LM4050 or LM4041.  
+3.3V 15 mW (max)  
+3.3V power down 40 μW (typ)  
+5V 33 mW (max)  
+5V power down 100 μW (typ)
