SBAS022C – NOVEMBER 1992 – REVISED FEBRUARY 2006  
Low-Power, 16-Bit, Sampling CMOS  
ANALOG-to-DIGITAL CONVERTER  
FEATURES  
DESCRIPTION  
35mW max POWER DISSIPATION  
The ADS7807 is a low-power, 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, clock, reference, and microprocessor inter-  
face with parallel and serial output drivers.  
50µW POWER-DOWN MODE  
25µs max ACQUISITION AND CONVERSION  
±1.5LSB max INL  
DNL: 16 bits “No Missing Codes”  
86dB min SINAD WITH 1kHz INPUT  
The ADS7807 can acquire and convert 16 bits to within  
±1.5LSB in 25µs max while consuming only 35mW max.  
Laser trimmed scaling resistors provide standard industrial  
input ranges of ±10V and 0V to +5V. In addition, a 0V to +4V  
range allows development of complete single-supply sys-  
tems.  
±10V, 0V TO +5V, AND 0V TO +4V INPUT RANGES  
SINGLE +5V SUPPLY OPERATION  
PARALLEL AND SERIAL DATA OUTPUT  
PIN-COMPATIBLE WITH THE 12-BIT ADS7806  
USES INTERNAL OR EXTERNAL REFERENCE  
0.3" DIP-28 AND SO-28  
The ADS7807 is available in a 0.3" DIP-28 and SO-28, both  
fully specified for operation over the industrial –40°C to  
+85°C temperature range.
