GENERAL DESCRIPTION  
PRODUCT HIGHLIGHTS  
The AD977/AD977A is a high speed, low power 16-bit A/D  
converter that operates from a single 5 V supply. The AD977A  
has a throughput rate of 200 kSPS whereas the AD977 has a  
throughput rate of 100 kSPS. Each part contains a successive  
approximation, switched capacitor ADC, an internal 2.5 V  
reference, and a high speed serial interface. The ADC is factory  
calibrated to minimize all linearity errors. The AD977/AD977A is  
specified for full scale bipolar input ranges of 10 V, 5 V and  
3.3 V, and unipolar ranges of 0 V to 10 V, 0 V to 5 V and  
0 V to 4 V.  
1. Fast Throughput  
The AD977/AD977A is a high speed, 16-bit ADC based on  
a factory calibrated switched capacitor architecture.  
2. Single-Supply Operation  
The AD977/AD977A operates from a single 5 V supply and  
dissipates only 100 mW max.  
3. Comprehensive DC and AC Specifications  
In addition to the traditional specifications of offset, gain  
and linearity, the AD977/AD977A is fully tested for SNR  
and THD.  
The AD977/AD977A is comprehensively tested for ac param-  
eters such as SNR and THD, as well as the more traditional dc  
parameters of offset, gain and linearity.
