Controllers Include DAC and Keypad Controller  
General Description  
Features  
The MAX1233/MAX1234 are complete PDA controllers in  
a 5mm × 5mm, 28-pin QFN package. They feature a  
12-bit analog-to-digital converter (ADC), low on-resis-  
tance switches for driving resistive touch screens, an  
internal +1.0V/+2.5V or external reference, 2°C accu-  
rate, on-chip temperature sensor, direct +6V battery mon-  
itor, keypad controller, 8-bit digital-to-analog converter  
(DAC), and a synchronous serial interface. Each of the  
keypad controllers’ eight row and column inputs can be  
reconfigured as general-purpose parallel I/O pins (GPIO).  
All analog inputs are fully ESD protected, eliminating the  
need for external TransZorb™ devices.  
o ESD-Protected Analog Inputs  
15kV IEC 1000-4-2 Air-Gap Discharge  
8kV IEC 1000-4-2 Contact Discharge  
o Single-Supply Operation  
+2.7V to +3.6V (MAX1233)  
+4.75V to +5.25V (MAX1234)  
o 4-Wire Touch-Screen Interface  
o Internal +1.0V/+2.5V Reference or External  
Reference (+1.0V to AV  
)
DD  
o SPI™/QSPI™/MICROWIRE™-Compatible 10MHz  
The MAX1233/MAX1234 offer programmable resolution  
and sampling rates. Interrupts from the devices alert the  
host processor when data is ready, when the screen is  
touched, or a key press is detected. Software-  
configurable scan control and internal timers give the user  
flexibility without burdening the host processor. These  
devices consume only 260µA at the maximum sampling  
rate of 50ksps. Supply current falls to below 50µA for  
sampling rates of 10ksps. The MAX1233/MAX1234 are  
guaranteed over the -40°C to +85°C temperature range.  
Serial Interface  
o 12-Bit, 50ksps ADC Measures  
Resistive Touch-Screen Position and Pressure  
Two Auxiliary Analog Inputs  
Two Battery Voltages (0.5V to 6V)  
On-Chip Temperature  
o 8-Bit DAC for LCD Bias Control  
o 4 × 4 Keypad Programmable Controller Offers Up  
to Eight GPIO Pins  
Applications  
o Automatic Detection of Screen Touch, Key Press,  
Personal Digital Assistants  
and End of Conversion  
Pagers  
o Programmable 8-, 10-, 12-Bit Resolution  
o Programmable Conversion Rates  
Touch-Screen Monitors  
Cellular Phones  
o AutoShutdown™ Between Conversions  
MP3 Players  
Portable Instruments
