The TLC1225I and TLC1225M converters are  
manufactured with Texas Instruments highly  
efficient Advanced LinCMOS technology. The  
TLC1225I and TLC1225M CMOS analog-to-  
digital converters (ADCs) can be operated with a  
single 5-V supply or with ±5-V supplies. The

5-V supply operation, grounding IN– corresponds  
to standard unipolar conversion. For ±5-V supply  
operation, grounding IN– corresponds to  
standard bipolar conversion. Conversion is  
performed via the successive-approximation  
method. The TLC1225x outputs the converted data in a parallel word and interfaces directly to a 16-bit data bus.  
Negative numbers are given in the 2s-complement data format. All digital signals are fully TTL and CMOS  
compatible.  
This converter uses a self-calibration technique by which seven of the internal capacitors in the capacitive array  
of the A/D conversion circuitry can be automatically calibrated. The internal capacitors are calibrated during a  
nonconversion capacitor-calibrate cycle in which all seven of the internal capacitors are calibrated at the same  
time. A conversion period requires only 24 clock cycles. Self calibration requires 300 clock cycles. The  
calibration or conversion cycle can be initiated at any time by issuing the proper command word to the data bus.  
The self-calibrating technique eliminates the need for expensive trimming of thin-film resistors at the factory and  
provides excellent performance at low cost.  
†
The conversion period is the reciprocal of the conversion rate and includes the access, sample, setup, and A/D conversion times.
