ES51992  
11,000 Counts ADC  
Description  
Features  
Max. 11,000 counts resolution  
ES51992 is an 11000-count dual-slope analog-  
to-digital converter (ADC). The conversion  
rate and buzzer frequency can be selected or  
decided by an external microprocessor. The  
conversion rate can be varied from 1.6 time/sec  
to 128 times/sec under 4MHz/12MHz crystal  
oscillation clock. Besides, ES51992 also  
provides multi-channels input, low battery  
detection, power-down mode, 50/60Hz line  
noise rejection selection, and I/O port level  
selection for flexible design.  
Conversion rate selectable by MPU  
command: 1.6/s Æ 128/s  
Input signal full scale: 110mV  
50/60Hz line noise rejection selectable by  
MPU command  
Low battery detection  
Multiple input channels for ADC  
3-wire serial bus and EOC signal for MPU  
I/O port  
-3V power operation with internal charge  
pumping circuit  
MPU I/O power level selectable by external  
control pin  
Zero calibration for eliminating offset error  
On-chip buzzer driving and frequency  
selectable by MPU command  
Support sleep mode by external CS(chip-  
select) pin  
Application  
Clamp meter  
Thermometer  
Portable instrumentation
