2.375V to 5.25V, 4-Wire Touch-Screen  
Controller  
General Description  
Features  
The MXB7843 is an industry-standard 4-wire touch-  
screen controller. It contains a 12-bit sampling analog-  
to-digital converter (ADC) with a synchronous serial  
interface and low on-resistance switches for driving  
resistive touch screens. The MXB7843 uses an external  
reference. The MXB7843 can make absolute or ratio-  
metric measurements. The MXB7843 has two auxiliary  
ADC inputs. All analog inputs are fully ESD protected,  
eliminating the need for external TransZorb™ devices.

o ꢂ-Wꢄre Toucꢆ-Screen InterfGce  
o RGtꢄometrꢄc Conversꢄon  
The MXB7843 is guaranteed to operate with a single  
2.375V to 5.25V supply voltage. In shutdown mode, the  
typical power consumption is reduced to under 0.5µW,  
while the typical power consumption at 125ksps  
throughput and a 2.7V supply is 650µW.

Low-power operation makes the MXB7843 ideal for bat-  
tery-operated systems, such as personal digital assis-  
tants with resistive touch screens and other portable  
equipment. The MXB7843 is available in 16-pin QSOP  
and TSSOP packages, and is guaranteed over the  
-40°C to +85°C temperature range.
