SBAS020D JANUARY 1996 REVISED OCTOBER 2006  
16-Bit, 10µs Sampling, CMOS  
ANALOG-to-DIGITAL CONVERTER  
FEATURES  
DESCRIPTION  
100kHz min SAMPLING RATE  
STANDARD ±10V INPUT RANGE  
86dB min SINAD WITH 20kHz INPUT  
±3.0 LSB max INL  
The ADS7805 is a complete 16-bit sampling, Analog-to-  
Digital (A/D) converter using state-of-the-art CMOS struc-  
tures. It contains a complete 16-bit, capacitor-based, Suc-  
cessive Approximation Register (SAR) A/D converter with  
Sample-and-Hold (S/H), reference, clock, interface for micro-  
processor use, and 3-state output drivers.  
DNL: 16 Bits No Missing Codes  
SINGLE +5V SUPPLY OPERATION  
PIN-COMPATIBLE WITH 12-BIT ADS7804  
The ADS7805 is specified at a 100kHz sampling rate and  
ensured over the full temperature range. Laser-trimmed  
scaling resistors provide an industry-standard ±10V input  
range while the innovative design allows operation from a  
single +5V supply, with power dissipation under 100mW.  
USES INTERNAL OR EXTERNAL  
REFERENCE  
FULL PARALLEL DATA OUTPUT  
100mW max POWER DISSIPATION  
0.3" DIP-28 AND SO-28  
The ADS7805 is available in a 0.3" DIP-28 and an SO-28  
package. Both are fully specified for operation over the  
industrial –25°C to +85°C range; however, they will function  
over the –40°C to +85C temperature range.
