DESCRIPTION  
Onboard Reference Buffer  
High-Speed Parallel Interface  
The ADS8402 is a 16-bit, 1.25 MHz A/D converter with an  
internal 4.096-V reference. The device includes a 16-bit  
capacitor-based SAR A/D converter with inherent sample  
and hold. The ADS8402 offers a full 16-bit interface and an  
8-bit option where data is read using two 8-bit read cycles.  
Power Dissipation: 155 mW at 1.25 MHz Typ  
Wide Digital Supply  
The ADS8402 has a unipolar differential input. It is  
available in a 48-lead TQFP package and is characterized  
over the industrial –40°C to 85°C temperature range.
